RTA SERIES II

መግቢያ

የእውነተኛ ጊዜ የድምጽ ተንታኝ (አርቲኤ) ሁለት አይነት መረጃዎችን በግራፊክ የሚያሳይ የድምጽ መለኪያ መሳሪያ ነው።

1. The frequency response of an audio system or device, and
2. The frequency response of the listening environment.

ይህ ዓይነቱ መረጃ የፒኤ ስርዓትን ለማመጣጠን፣ የግብረመልስ ትኩስ ቦታዎችን ወይም "አንጓዎችን" ለማግኘት በማጠናከሪያ ሁኔታዎች ውስጥ እና የሌሎች የድምጽ መሳሪያዎችን ድግግሞሽ ምላሽ ለማስተካከል በጣም ጠቃሚ ነው።
RTAs that show both the entire audible frequency spectrum (20 Hz to 20 kHz) and its entire dynamic range (loudness from 0 dB to 120 dB) are called spec-trum analyzers. RTAs that show portions of the dynamic range are called “window” RTAs.

ስለ ዶድ RTA
DOD ኤሌክትሮኒክስ RTA Series II የመስኮት አይነት RTA ነው። የሚሰማውን ፍሪኩዌንሲ ስፔክትረም (ከ20 ኸርዝ እስከ 20 ኪሎ ኸርዝ) ይሸፍናል፣ እና ለሚሸፍናቸው 31 የድምጽ ድግግሞሽ ባንዶች አምስት የ LED ደረጃ መለኪያ አለው።
የRTA Series II የተስተካከለ የድምጽ መለኪያ ማይክሮፎን ያካትታል። ይህ ማይክሮፎን በ 40 ጫማ ገመድ የተገጠመለት ሲሆን ይህም የድምጽ ስርዓቱን ግምገማ በሚያደርጉበት ጊዜ ማይክሮፎኑን በበርካታ ቦታዎች በማጠናከሪያ ቦታ ላይ ለማስቀመጥ ያስችልዎታል. ይህ ማይክሮፎን ብቻ በ RTA ፓነል ፊት ላይ ባለው ጃክ ውስጥ መሰካት አለበት። ሌሎች ማይክሮፎኖች ሊበላሹ ወይም የተሳሳቱ ንባቦችን ሊሰጡ ይችላሉ።
የ RTA ስሜታዊነት የግቤት ደረጃ መቆጣጠሪያን በመጠቀም ሊስተካከል ይችላል፣ እና የ RTA መስኮት የ Resolution ማብሪያ / ማጥፊያን በመጠቀም ሊሰፋ ወይም ሊጠብ ይችላል። ይህ ማብሪያ / ማጥፊያ የ LED ማሳያ ክልልን በዲቢ በአንድ LED እንዲመርጡ ያስችልዎታል። በ LED ደረጃ (ለ 1 ዲቢቢ ሰፊ መስኮት) ወይም 4 ዲቢቢ በ LED ደረጃ (ለ 3 ዲቢቢ ሰፊ መስኮት) 12 ዲቢቢ መምረጥ ይችላሉ ።

The DOD RTA Series II also has its own internal pink noise generator and level control. Pink noise is defined as an audio signal that contains all frequencies at equal energy levels. For this reason, pink noise sounds a lot like static. Pink noise is useful when setting up P.A. systems and audio systems when you need to see the frequency response of the system.

በክፍሉ የኋላ ክፍል ላይ ከሌሎች የመለኪያ ማይክሮፎኖች ጋር ለመጠቀም ረዳት የማይክሮፎን መሰኪያ እና ለሮዝ ጫጫታ ጄኔሬተር የውጤት መሰኪያ አለ። ሮዝ ጫጫታ ሲጠፋ፣ ምልክቱ በRTA በኩል እንዲዞር እና በአፈጻጸም ጊዜ ክትትል እንዲደረግበት ይህ መሰኪያ እንደ የድምጽ ውፅዓት ሆኖ ይሰራል። እንዲሁም በሲስተሙ ውስጥ መሳሪያዎችን በቀጥታ ለመተንተን የሚያስችል የግብዓት መሰኪያ አለ.

የፊት ፓነል መቆጣጠሪያዎች

• የኃይል መቀየሪያ Applies power to the RTA.
• LEDs አሳይ፡ Each vertical column of LEDs displays the signal level within that frequency band. Each frequency is on a 1/3rd octave ISO centered point from 20 Hz to 20kHz.
• የግቤት ደረጃ ቁጥጥር፡- This control sets the input level from the calibrated microphone input jack, the line level input jack, or the auxiliary microphone input jack. Use this control to set the response of the display to a useful range.
• የጥራት መቀየሪያ: This push-push switch selects the size of step between LEDs to either 1 dB or 3 dB. This effectively widens or narrows the window that the RTA shows, giving you a wider or narrower view of the incoming sig-nal.
• Pink Noise Switch: This push-push switch turns the pink noise generator on or off. To prevent damage to your audio system, be sure to turn down your audio system’s gain control before turing on the pink noise generator.
• Pink Noise Level Control: This rotary potentiometer sets the output level of the pink noise generator. To prevent damage to your audio system, be sure to set this control to minimum before turning on the pink noise generator.
• Calibrated Microphone Input Jack: This jack supplies power to the calibrat-ed microphone. Plug only the calibrated microphone provided with the RTA into the jack on the front panel of the RTA. Other microphones may be dam-aged or give inaccurate readings.

የኋላ ፓነል መቆጣጠሪያዎች

Auxiliary Microphone Input Jack: A female XLR-type connector intended for use with microphones other than the calibrated microphone provided with theRTA. This jack accepts low impedance microphones.

• Line Input Jack: This is a 1/4-inch phone jack that may be connected to unbalanced line level sources.
• Line Output/Pink Noise Output Jack: A 1/4-inch phone jack that provides connection to unbalanced line level inputs. Engaging the pink noise switch on the front panel causes the pink noise generated by the RTA to be output through this jack. Adjust the level for the pink noise generator with the rotary potentiometer on the front panel of the RTA. Disengaging the pink noise switch on the front panel allows this jack to act as a pass-through to the sig-nal introduced at the line input jack.

የትግበራ ማስታወሻዎች
RTA ን ከመጠቀምዎ በፊት ለመረዳት ጥቂት ጠቃሚ ሀሳቦች እዚህ አሉ።
አርቲኤ መለኪያ መሳሪያ ነው። ድምጹን አይነካውም ወይም አይለውጥም. በድምጽ ስርዓት ውስጥ አስፈላጊውን የድግግሞሽ ምላሽ ለውጦችን ለማድረግ፣ ግራፊክ አመጣጣኝ ወይም ፓራሜትሪክ አመጣጣኝ ሊኖርዎት ይገባል። አርቲኤ የሚለካው በ1/3ኛ octave ጭማሪዎች ውስጥ በመሆኑ፣ በስርዓቱ ውስጥ 1/3ኛ octave ግራፊክ አመጣጣኝን መጠቀም በጣም ቀላል ነው፣ ለምሳሌ DOD's 231 Series II፣ 431 Series II፣ ወይም 831 Series II።
ፓራሜትሪክ አመጣጣኝ እንዲሁ ጠቃሚ ነው። የፓራሜትሪክ አመጣጣኞች ግን እንደ ግራፊክ አመጣጣኞች ለመጠቀም ቀላል አይደሉም።

ማስታወሻ፡- A lot of “fixing” can be done by simply repositioning the microphones and speakers in a system.
RTA በድምጽ ስርዓትዎ ውስጥ የድግግሞሽ ምላሽ ችግሮችን እንዲያገኙ ያግዝዎታል፣ እና አመጣጣኝን በመጠቀም እነዚህን ችግሮች ያርሙ። ድምጹን ማስደሰት የሚጀምረው የስርዓተ-ፆታ ችግሮችን ካስተካከሉ በኋላ ነው, እና ጥሩ ልምድ ባለው ጆሮ ይከናወናል. “ጠፍጣፋ” ሲስተሞች በአብዛኛዎቹ የማጠናከሪያ ሁኔታዎች ለአድማጩ በጣም የሚያሸማቅቁ ወይም ብሩህ ይመስላሉ፣ ስለዚህ ስርዓቱ የተሻለ ድምጽ እንዲኖረው የእኩል አድራጊው መቼት ሁልጊዜ ይቀየራል።
When measuring the sound in an enclosed sound reinforcement application, use more than one microphone location. This is because speaker dispersion characteristics vary greatly as you move around the room (particularly with multiple driver systems). If you find that different areas of the room behave differently, try to average the settings on the equalizer to correct the room as a whole.

ስርዓቱን በሮዝ ድምጽ ማፈንዳት አያስፈልግዎትም። ማንኛውንም የድባብ ክፍል ጫጫታ (እንደ የአየር ኮንዲሽነሮች ወይም የትራፊክ ጫጫታ ያሉ) ለማሸነፍ ከ RTA በቂ ደረጃ ይጠቀሙ። የ RTA ትብነት ከፍ ያለ መሆን አለበት ስለዚህ ሮዝ ጩኸቱን ሲያጠፉ በክፍሉ ውስጥ ባለው ጫጫታ ከ LEDs ውስጥ አንዳቸውም አይበሩም።
ከ 3 Hz በታች በሆኑ ድግግሞሾች ላይ ባለ 500 ዲቢ ጥራት ቅንብርን ይጠቀሙ። የሮዝ ጩኸት ከፍተኛ ምላሽ በ1 ዲቢቢ ጥራት ቅንብር ውስጥ መንሳፈፍን ያስከትላል፣ ይህም በፍጥነት ለማረም አስቸጋሪ ያደርገዋል። ከ 1 Hz በላይ ድግግሞሾችን ለመለካት የ500 ዲቢ ጥራት ቅንብርን ይጠቀሙ።

የመደበኛ ማጠናከሪያ ስርዓት ዋና ዋና ተናጋሪዎችን ማመጣጠን
በመጀመሪያ የተስተካከለውን ማይክሮፎን ከ 3 እስከ 4 ጫማ ከዋናው ድምጽ ማጉያዎች ፊት ለፊት በድምጽ ማጉያው ዘንግ ላይ ያድርጉት። በዚህ ወሳኝ ርቀት ውስጥ በስርዓቱ ላይ የመጀመሪያውን ማስተካከያ እንዲያደርጉ ይህ በተለይ ከቤት ውስጥ ስርዓት ጋር በጣም አስፈላጊ ነው (የክፍሉ አከባቢ መነቃቃቱ የስርዓቱን ምላሽ የመነካካት እድል ከመፈጠሩ በፊት)።
ስርዓቱን ላለማፈንዳት ጥንቃቄ በማድረግ ሮዝ ጫጫታ ማመንጫውን ያብሩ። የስርዓቱን ግብአት ዝቅ ማድረግዎን ያረጋግጡ፣ ከዚያ የሮዝ ጫጫታ ደረጃን ወደሚሰማ የመለኪያ ደረጃ ይጨምሩ። የግራፊክ አመጣጣኝን በመጠቀም የስርዓቱን ምላሽ በተቻለ መጠን ጠፍጣፋ እንዲሆን ያስተካክሉ።
ስርዓቱን በቅርብ መስክ ላይ ካስተካክሉ እና ካረሙ በኋላ የተስተካከለ ማይክሮፎኑን ወደ ክፍሉ ያንቀሳቅሱት ይህም ከድምጽ ማጉያዎቹ የተለመደ የማዳመጥ ርቀት። ማይክሮፎኑን ከድምጽ ማጉያዎቹ ሲያንቀሳቅሱ ሁለት ነገሮችን ያስተውላሉ፡-

1. The high frequency response of the system will fall off, usually starting at about 10 kHz.
2. When there are other structures nearby, one or more peaks or dips will appear in the low end.

The high frequency roll off is caused by absorption of high frequencies in the air. Don’t adjust the highs any more by measurement. The highs can be adjusted by ear using program material you’re familiar with. Be sure to check several positions in the room and compromise the equalization/attenuation setting for the best possible sound. This may be done either with the equalizer or by aiming the tweeters of the main speakers differently.

ዝቅተኛ ድግግሞሽ ዳይፕስ እና ቁንጮዎች ከክፍል ጋር የተገናኙ ናቸው, እና በተወሰነ ደረጃ ሊስተካከሉ ይችላሉ. ማናቸውንም እርማቶች ከማድረግዎ በፊት የከፍታዎቹ እና የዲፕስ አቀማመጥ ምን ያህል ጥገኛ ሊሆኑ እንደሚችሉ ለማወቅ የተስተካከለ ማይክሮፎኑን በክፍሉ ውስጥ ማንቀሳቀስዎን ያረጋግጡ። በክፍሉ ውስጥ የት እንደሚገኙ ሲያውቁ, ምን ያህል ድግግሞሾች እንደሚከሰቱ እና የእነሱ ampበሥርዓት፣ በአመጣጣኝ ልታያቸው ልትሞክር ትችላለህ።
Finally, play some program material with which you’re familiar and set the sys-tem’s response to your taste.

Another method for equalizing a monitor system uses the stage microphones without the RTA’s calibrated microphone. Most reinforcement type microphones are not flat in their frequency response. This procedure, however, takes the stage microphone’s response into account as you equalize the system.

• Use the system’s own microphones to sampየድምጽ መስኩ በ stage using the pink noise generator signal. Have someone stand in front of the microphone or place their hand in front of the microphone so that you can see what effect it may have on the system’s feedback and overall sound.
• This is the best way to minimize feedback and get the highest sound level from the monitors, but you will sacrifice some sound quality.
• Once you’ve equalized the system with one of the above procedures, the following setup will help you find the howls and ringing that inevitably occur as you use the system (this procedure can be used for both monitors and mains).
• Use a mono or auxiliary output or loop through the RTA to your speakers.
• Adjust the level input to the RTA so that the “+” LEDs flash on signal peaks. Set the resolution of the RTA to the 3 dB range.
• After feedback occurs, watch the RTA. The last frequency band to decay is where the feedback is occurring. This frequency may then be notched out using the equalizer.

844 SERIES II

መግቢያ
The DOD 844 Series II Quad Noise Gate consists of 4 independent noise gates in a single rack space unit. Threshold, release time, and attenuation (0 dB to 90 dB) for each gate are user controllable. Special features include a Key input for gating, or “keying”, from a signal other than the input. A control out-put is also provided for triggering other devices with a 5 volt pulse from the selected channel when the input for that channel rises above the threshold. Monitoring the operation of the 844 is made simple with front panel LEDs that indicate the operating status of each channel (lit when input signal is being gated).

መጫን
Install the 844 in a rack with the provided rack screws. Route the AC cord away from audio lines to a convenient outlet. Connections to the input and output jacks are made using balanced tip-ring-sleeve or unbalanced 1/4″ tip-sleeve phone plugs.
FOR BALANCED CONNECTION: wire the plug as follows:

አፕሊኬሽን
The 844 Series II Quad Noise Gate can be used in a variety of situations. The  most typical use is a standard noise gate. With the Key Source switch set to INT and the Attenuation control set to 90 dB, the unit will attenuate the input signal when its level falls below the threshold level. The release control (fade time) can be set to begin the attenuation very slowly or very quickly as desired.

• Set the Attenuation to 90 dB and set the threshold so that the gate only opens when the drum is struck. Less attenuation may be needed if the effect of the gate is too noticeable.
• Switch the Key Source control to Ext. The detector will now ignore the high frequency signals (in this case, the cymbals), and will allow the drum signal though only when the drum is struck.

ለ example, if the signal appearing at the channel input of the gate is a sus-tained guitar chord, the resulting output would be the chord sound “played” to the rhythm of the drum machine. Using this technique can produce some interesting results. Try using different Key sources to trigger the gate. You may find something you like.
The Control output is a unique feature of the 844 Series II. This output can be used to trigger a drum machine or sequencer in time with whatever is input into either the channel input or the Key input, offering a quick means of syn-chronizing other equipment to the input.

መቆጣጠሪያዎቹ እና ተግባሮቻቸው እንደሚከተለው ናቸው-

• የበሩ ወሰን The Gate Threshold controls the level at which the 866 will allow the input signal through to the compressor section of the unit. If the signal level is below the threshold, no signal is allowed to pass. The red LED  will light whenever the signal is being gated. To disable the gating action, set the Gate Threshold control to the full counter-clockwise position (the gate control is fully independent of all other controls on the 866).
• ግቤት Gain: The Input Gain control allows you to adjust the signal level to the compressor. This control directly affects the setting of the Gate Threshold control and the Compressor Threshold control, and is active even when the Compress switch is in the out position. With the Input Gain control set to 0 dB, over 20 dB of headroom is available to the compressor.
• Compressor Threshold: This control sets the level at which the compressor begins to act. The Input Gain control affects the Compressor Threshold set-ting by changing the overall level that the compressor sees. When used in combination with the Input Gain control, the Compressor Threshold control can be adjusted to accommodate a wide range of signal levels.
• ምጥጥን Determines the amount, or ratio, of compression applied to the incom-ing signal. A ratio of 1:1 means that no compression is applied; a ratio of less than 10:1 is generally considered compression; a ratio of more than 10:1 is generally considered limiting; a ratio of ∞:1 allows no signal above the Compressor Threshold level setting.
• ጥቃት፡- This control adjusts the speed with which the compressor reacts to an increase in input signal level above the threshold. Shorter attack time set-tings will cause the compressor to react more quickly to transients, giving an added measure of protection to sensitive equipment. Longer attack times allow more of the transient to pass, yielding a more natural sound while still compressing the dynamic range of the signal.
• መልቀቅ፡- The Release control adjusts the speed with which the compressor reacts to a decrease in input signal level above the threshold. Faster release time settings can cause a sudden increase in noise on peaks for some pro-gram material as the compressor lets go. This effects is known as “breath-ing”. Increasing the Release time setting will help minimize breathing.
• ውፅዓት Gain: Determines the output level of the compressor. This is useful when making up for gain lost in the compression process. The output level is active only when the Compress switch is depressed.

• Compress: The compress switch activates the compressor when depressed.
• የስቲሪዮ ማገናኛ፡ Depressing the Stereo Link switch links the two compressor channels for stereo operation. In stereo mode, the compressor will react to either channel, while reducing gain in both channels. Both channels of the 866 are identical in control and function EXCEPT when placed in the stereo mode. In stereo mode, the channel 1 controls become the master controls for both channels, while the Input Gain controls remain independent for each channel.

የኋላ ፓነል ግብዓቶች እና ውጤቶች እና ተግባሮቻቸው እንደሚከተለው ናቸው ።

• ግቤት: The inputs of the 866 will accept line level signals, either balanced or unbalanced. A 1/4″ tip-ring-sleeve phone jack and an RCA phono jack are pro-vided for each input. Using the 1/4″ input jack disconnects the RCA input jack.
• ውጤት፡ The outputs of the 866 will drive either balanced or unbalanced lines. A 1/4″ tip-ring-sleeve phone jack and an RCA phono jack are provided for each output. Both the 1/4″ phone jacks and the RCA jacks may be used at the same time.
• የጎን ሰንሰለት ግቤት: Allows access to the signal detector circuit of the com-pressor, permitting control of the compressor with another signal for such applications as “ducking”. When used with the Side Chain Output, the original input signal can be modified for applications such as “deessing”. Inserting a plug into this jack opens the internal side chain path so that the detector will only respond to the signal at this jack. In the stereo mode, both channels of the compressor react as one.
• Side Chain Output: The Side Chain Output is the buffered output normally fed to the detector. It is used in conjunction with the Side Chain Input to modify the detector signal for special applications such as “ducking” and “deessing”. For these applications, the Side Chain Output signal is sent to a signal processor and returned through the Side Chain Input.

The Compressor Threshold controls the point above which the compressor begins to reduce the gain. For compression, the Compressor Threshold is set low, so that even low level signal will activate the compression. For limiting, the Compressor Threshold is set high so that all of the dynamics of the signal are preserved, but extremely high levels are reduced to protect ampliifiers, ድምጽ ማጉያዎች, ወይም ቴፕ ሙሌት ለመከላከል. በዚህ መተግበሪያ ውስጥ ጠቋሚው ከመነሻው በታች ያለውን የምልክት ደረጃ ለውጦችን ችላ ይላል።

The 866 features a “soft knee” compression curve for more natural sounding compression. This means that as the signal level approaches the threshold setting, the compressor starts to react. The ratio, or slope, of the gain reduction continues to increase gradually as the signal passes above the threshold until it reaches the final gain slope set by the Ratio control. This feature makes the compressor’s operation less obtursive by easing into full com-pression. As you increase the compression Ratio, the “knee” gets sharper, and the gain reduction increases more rapidly with increased signal. Protective limiting requires a high compression Ratio setting, so that full compression is reached quickly.
The time it takes for the detector to react to an increase in signal level is deter-mined by the Attack control setting. To preserve some of the transient punch of a signal, the Attack time should be set fairly high. This allows the user to compress the overall dynamic range of a signal while still preserving the natural, open feel of the sound. For limiting, the Attack time should be short, so that potentially damaging transients don’t get past the limiting protection of the compressor.

Release time is the opposite of attack time. The Release time setting deter-mines the amount of time the detector takes to react to a decrease in signal level and to release the action of the compression. Faster release times will help preserve the original dynamics of the signal, but may cause a problem in some program material. This effect is called “pumping” or “breathing” . As the compressor lets go of the signal, the level of the signal (and the noise floor) is allowed to rise. When the next transient hits, the signal level is pushed down again according to the Attack time setting. Breathing can be minimized using longer Release times, which smooth out the action of the compressor.
Once a signal has crossed the threshold, the compressor must be told how much to reduce the gain. The Ratio control determines the amount of gain reduction, expressed as a ratio, adjustable from 1:1 (no gain reduction) to ∞:1 (the signal is not allowed to rise above the Threshold level). Compression ratios express the ratio between the input signal level and the desired output level. A compression ratio of 2:1 means that for an increase of 2dB above the threshold input signal, the compressor output will rise only 1 dB. At a ratio of 5:1, an input increase of 5dB above the threshold will yield an output increase of 1 dB, and so forth. The setting of the Ratio control is dependent upon the  application in which the compressor is to be used.

Hiss and signal processor idling noise are common sound reinforcement problems. The more signal processors there are in line with the program material, the more noise is produced at the final output stage. For this rea- son DOD has incorporated a noise gate in the 866. A gate acts like a compressor in reverse. When a signal crosses the gate threshold, it is allowed to pass unaffected. When the signal level falls below the gate threshold level,  the signal gain is attenuated, effectively shutting it off. The Gate Threshold control of the 866 allows the user to adjust the threshold level of the noise gate. When the control is in the fully counter clockwise position, the noise gate is inactive and all signals will pass through.
The Output Gain control allows the user to make up for gain lost in the com-pression process and to set the output level of the compressor for compatibility with other equipment.

The uses for a compressor don’t end with compression and protective limit-ing. Applications such as “ducking”, “deessing”, and “de-thumping” can be achieved with equal ease, and their uses are many.

The voice and crowd signals are then mixed together. For this type of application, the com-pression ratio is kept fairly low with long attack and release times.

The Side Chain output is provided so that the controlling signal (not the pro-gram material) may be modified before reaching the detectors.
The most common use of this technique is for deessing. A d-esser reduces the high frequency sibilance in the “s”s and “t”s of speech to prevent tape saturation or high frequency driver damage. Connect the Side Chain Output to an equalizer whose output is connected to the Side Chain Input of the 866.
The areas where most of the “ess” energy is located are between 2.5 kHz and 10 kHz. If these areas are boosted on the equalizer, the gain of the program material will be reduced more by the compressor because of the excess gain  in that frequency range, thus reducing the sibilance of the program material. Attack and Release times should be set fairly short, and the compression ratio should be below 8:1.
