Features:
POWER STATUS LED
- This bio-color LED illuminates green when power is on and no problems are present. If one of the protection circuits comes on, it will change to red.
PHASE SHIFT
- Use this switch to help compensate for time alignment problems in the system. Such problems usually result from having the subwoofer at a different distance from the listener than the other speakers in the system.
AUTO POWER ON
- The AUTO POWER ON(ON/OFF) is for high level (speaker-level) connections. When the switch is in the “ON” position, the subwoofer AUTO POWER ON when there is signal input. If the amplifier detected no signal input, the amplifier will auto turn off. If you prefer to use the remote turn on/off connection, the switch is in the OFF position.
LOW PASS FILTER
- This control permits you adjust the frequency range you want the subwoofer amplifier to receive. The subwoofer will reproduce all sound BELOW the frequency you set.
BASS BOOST
- The BASS BOOST feature will increase the sound level in the bass frequencies.
INPUT GAIN CONTROL
- Turn the head unit on (and the subwoofer wil turn on via the remote connection), Tum the head unit volume to about 2/3 full level. Slowly turn up the subwoofer input gain control until you hear a small amount of distortion. Then reduce the level until the distortion is completely gone. Level the control at this setting.
REMOTE LEVEL CONTROL
- Attach the included remote level control to control the volume level of the subwoofer independently.
HIGH LEVEL (speaker low) INPUTS
- If your head unit does not have RCA outputs you can use the speaker outputs for the audio source for the subwoofer. Use the supplied cable and wire harness and connect the outputs properly as shown in the connection diagram in this manual.
LOW LEVEL RCA INPUTS
- Low level inputs are the recommended way to introduce the audio signal to the subwoofer if RCA outputs are present on your head unit or other signal source (such as a sound processor).
FUSE
- Do not use a fuse with a different value and NEVER replace the fuse with a wire or coin. K. POWER INPUT TERMINAL The terminal is using for power source and tum ON/OFF
