• Güç Düğmesi: Geçiş yapar ampAmplifikatörün gücü açık veya kapalı.
• Phase Control (0° - 180°): Adjusts the phase of the subwoofer output relative to the main speakers. This helps to ensure that the subwoofer's sound waves align correctly with those of the main speakers, preventing cancellation or reinforcement issues at the crossover frequency.
• FREQ (Crossover Frequency) Control: Sets the upper frequency limit for the subwoofer. Frequencies above this setting will be filtered out. Adjustable from approximately 40Hz to 120Hz.
• GAIN (Ses Seviyesi) Kontrolü: Adjusts the overall output level of the subwoofer amplifier. Use this to balance the subwoofer's volume with the rest of your audio system.

4.2 Arka Panel Bağlantıları ve Kontrolleri

The rear panel houses all the input and output connections, along with additional settings for advanced configuration.

• HI LEVEL OUT (Speaker Level Output): Passes the full-range audio signal from the HI LEVEL IN to your main speakers.
• LINE IN (RCA Input): Standard RCA stereo inputs for connecting to the pre-out or line-out of your receiver or audio source.
• LINE OUT (RCA Output): Passes the audio signal from the LINE IN to another amplifier veya ses cihazı.
• LFE INPUT (RCA Input): Dedicated input for connecting to the LFE (Low-Frequency Effects) output of an AV receiver. This bypasses the amplifier's internal crossover, relying on the receiver's bass management.
• BASS BOOST (Level & Freq):
  • Level (0dB to 12dB): Adjusts the intensity of the bass boost.
  • Freq (25Hz to 50Hz): Selects the center frequency at which the bass boost is applied.

6.2 Kontrollerin Ayarlanması

Optimal sound quality depends on proper adjustment of the amplifier's controls to match your subwoofer and listening environment.

• GAIN (Volume): Start with the GAIN control at its minimum setting. Play some audio with significant bass content. Slowly increase the GAIN until the subwoofer's output blends seamlessly with your main speakers. Avoid setting the gain too high, as this can lead to distortion.
• FREQ (Crossover Frequency):
  • Eğer kullanıyorsanız LFE GİRİŞİ, this control is bypassed. Set your AV receiver's subwoofer crossover frequency.
  • Kullanıyorsanız HAT GİRİŞİ or YÜKSEK SEVİYE, adjust the FREQ control to blend the subwoofer's output with your main speakers. A good starting point is typically 80Hz-100Hz, but this may vary depending on the size and frequency response of your main speakers. Smaller main speakers usually require a higher crossover frequency.
• PHASE (0° - 180°): The phase control helps to ensure that the subwoofer's sound waves are in sync with your main speakers.
  • Play music with a consistent bass line.
  • While listening from your primary listening position, slowly adjust the PHASE control from 0° to 180°.
  • Stop at the position where the bass sounds the loudest and most impactful. If the bass sounds weak or hollow, try adjusting the phase.
• BAS KUVVETLENDİRME: Use the BASS BOOST controls (Level and Freq) to fine-tune the low-frequency response.
  • Frekans: Select the specific low frequency (25Hz to 50Hz) you wish to boost.
  • Seviye: Adjust the amount of boost (0dB to 12dB) at the selected frequency. Use sparingly to avoid muddy or boomy bass.

7. Bakım

• Temizlik: Bağlantıyı kesin amplifier from power before cleaning. Use a soft, dry cloth to wipe down the exterior. Do not use liquid cleaners or aerosol sprays.
• Havalandırma: Ensure that the ventilation openings are not blocked by dust or debris. Periodically check and clean if necessary to maintain proper airflow.
• Depolamak: Eğer depolanıyorsa ampUzun süre kullanacaksanız, güç kaynağından ayırın ve doğrudan güneş ışığından ve aşırı sıcaklıklardan uzak, serin ve kuru bir yerde saklayın.
