  1. POWER Switch: Turns the amplifier ON or OFF.
  2. TONE / DIRECT Switch: Selects between Tone control mode (Treble and Bass knobs active) and Direct mode (tone controls bypassed for a flat frequency response).
  3. TREBLE Knob: Adjusts the high-frequency response.
  4. BASS Knob: Adjusts the low-frequency response.
  5. VOLUME Knob: Controls the overall output volume.

Rear Panel Connections

  1. AUDIO INPUT (RCA): Connect your audio source (e.g., PC, MP3 player, phone) using RCA cables.
  2. SPEAKER IMPEDANCE 4-8Ω: Connect your passive speakers to these terminals. Ensure correct polarity (+ to + and - to -).
  3. POWER INPUT (DC 12-13.5V): Connect the external DC power adapter (not included).

Setup Guide

  1. Connect Speakers: Connect your passive speakers to the "SPEAKER IMPEDANCE 4-8Ω" terminals on the rear panel. Ensure the positive (+) terminal of the amplifier connects to the positive (+) terminal of the speaker, and the negative (-) terminal of the amplifier connects to the negative (-) terminal of the speaker. Incorrect polarity can affect sound quality.
  2. Connect Audio Source: Use an RCA cable to connect your audio source (e.g., PC, MP3 player, smartphone via adapter) to the "AUDIO INPUT" RCA jacks on the rear panel.
  3. Connect Power: Connect a compatible DC 12-13.5V 3A power adapter (not included) to the "POWER INPUT" jack on the rear panel. Then, plug the power adapter into a wall outlet.
  4. Initial Power On: Ensure the VOLUME knob is set to minimum before turning on the amplifier.

Operation

  1. Power On: Press the POWER switch on the front panel to turn on the amplifier. The power indicator light will illuminate.
  2. Adjust Volume: Slowly turn the VOLUME knob clockwise to increase the sound level to your desired listening volume.
  3. Tone Control:
    • Set the TONE / DIRECT switch to TONE position to enable bass and treble adjustments.
    • Use the BASS knob to adjust the low-frequency response.
    • Use the TREBLE knob to adjust the high-frequency response.
  4. Direct Mode: Set the TONE / DIRECT switch to DIRECT position to bypass the tone control circuit. This provides a flat frequency response, often preferred by audiophiles for a more "pure" sound.
  5. Power Off: When finished, turn the VOLUME knob to minimum, then press the POWER switch to turn off the amplifier.

Maintenance

  • Cleaning: Use a soft, dry cloth to clean the exterior of the amplifier. Do not use liquid cleaners or aerosols.
  • Ventilation: Ensure the amplifier has adequate ventilation. Do not cover the ventilation slots.
  • Storage: If storing the amplifier for an extended period, disconnect it from the power source and store it in a cool, dry place.
  • Avoid Moisture: Keep the amplifier away from water and excessive humidity.
