4.1 አቀማመጥ

The placement of your subwoofer significantly impacts its performance. Experiment with different locations to find the best sound for your room. General guidelines:

• የማዕዘን አቀማመጥ ፦ Often provides the most output and impact, but can sometimes lead to boomy or uneven bass.
• የክፍሉ ፊት ለፊት፦ Placing the subwoofer near your front speakers can improve integration and soundstage coherence.
• የመሃል ግድግዳ አቀማመጥ፡ Can offer a more balanced bass response than corner placement.
• በርካታ ንዑስ-ዋውፈርዎች፦ Using two or more subwoofers can provide smoother bass distribution throughout the listening area.

Ensure the subwoofer is placed on a stable, level surface. The included rubber feet help isolate vibrations.

4.2 ግንኙነቶች

Before making any connections, ensure all audio components are powered off.

1. LFE Input (Recommended for Home Theater):
   Connect a single RCA cable from the LFE or Subwoofer output of your AV receiver/processor to the LFE IN jack on the DN12. This connection bypasses the subwoofer's internal low-pass filter, allowing your receiver to manage bass management.
2. Line In (Stereo RCA):
   For stereo systems or receivers without an LFE output, connect RCA cables from the pre-out (left and right) of your amplifier/receiver to the LINE IN (Left/Right) jacks on the DN12. In this configuration, the subwoofer's internal low-pass filter will be active.
3. High Level Input (Speaker Level):
   የእርስዎ ከሆነ amplifier does not have LFE or line-level outputs, connect speaker wires from the main speaker outputs of your amplifier to the HIGH LEVEL INPUT (Left/Right) binding posts on the DN12. Ensure correct polarity (+ to + and – to –).

4.3 የኃይል ግንኙነት

Once all audio connections are made, connect the supplied power cord to the AC power input on the subwoofer and then to a wall outlet. The subwoofer is designed for corded electric power.

5.1 ማብራት / ማጥፋት

The DN12 features a power switch on the rear panel with three settings:

• በርቷል ንዑስ ሰሪው ያለማቋረጥ በርቷል።
• ራስ-ሰር የድምጽ ምልክት ሲገኝ የንዑስ ድምጽ ማጉያው በራስ-ሰር ይበራል እና ከእንቅስቃሴ-አልባነት ጊዜ በኋላ ወደ ተጠባባቂ ሁነታ ይገባል።
• 12V ቀስቅሴ፡ The subwoofer powers on/off in conjunction with a 12V trigger signal from a compatible device (e.g., AV receiver).

5.2 Controls (Rear Panel & Remote)

The following controls are available on the rear panel and via the remote control:

• ድምጽ Adjusts the overall output level of the subwoofer. Start with a moderate level and adjust to blend with your main speakers.
• ዝቅተኛ ማለፊያ፡ Sets the upper frequency limit for the subwoofer. This is typically set between 80Hz and 120Hz, depending on your main speakers' low-frequency extension. If using the LFE input, this control is usually bypassed by the receiver's bass management.
• ደረጃ፡ Adjusts the phase of the subwoofer output (0 to 360 degrees) to ensure it aligns acoustically with your main speakers. Experiment with settings to achieve the most coherent bass.
• EQ: Selects between three equalization modes: ጠፍጣፋ (neutral response), ጥልቅ (extended low-frequency response), and ጮክ ብሎ (increased output for maximum impact).
• ማሳያ Controls the brightness or turns off the front panel display.

5.3 የመጀመሪያ ማዋቀር እና ማስተካከያ

After connecting and powering on, perform the following steps:

1. Set the subwoofer volume to a low level.
2. If your AV receiver has an auto-calibration system (e.g., Audyssey, MCACC, YPAO), run it according to your receiver's instructions. This will automatically set volume, phase, and crossover frequency.
3. If calibrating manually, play familiar audio content and adjust the subwoofer's VOLUME, LOW PASS, and PHASE controls until the bass blends seamlessly with your main speakers without being overly prominent or lacking.
