The Safety of Your Ears is in Your Hands
Get the most out of your equipment by playing it at a safe level—a level that lets the sound come through clearly without annoying blaring or distortion and, most importantly, with–out affecting your sensitive hearing. Sound can be deceiving. Over time, your hearing “comfort level” adapts to higher volumes of sound, so what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.
ESTABLISH A SAFE LEVEL:
- Set your volume control at a low setting.
- Slowly increase the sound until you can hear it comfortably and clearly, without distortion.
- Once you have established a comfortable sound level, set the dial and leave it there.
BE SURE TO OBSERVE THE FOLLOWING GUIDELINES:
- Do not turn up the volume so high that you can’t hear what’s around you.
- Use caution or temporarily discontinue use in potentially hazardous situations.
- Do not use headphones while operating a boat; the use of headphones may create a traffic hazard and is illegal in many areas.
About This Product
This product is a mono amplifier for subwoofer. If both L (left) and R (right) channels are connected to the RCA input of this product, output is mixed because this product is a mono amplifier.

Important (Serial number)
The serial number is located on the bottom of this unit. For your own security and convenience,be sure to record this number on the enclosed warranty card.
Setting the Unit
To adjust the switch, use a flat head screwdriver if needed.
- POWER/PROTECT indicator
The power indicator lights up to indicate power ON.
- If something is not normal, the indicator turns red,
2. GAIN (gain) control
If the output remains low, even when the stereo volume is turned up, turn the controls to a lower level. If distortion occurs when the stereo volume is turned up, turn these controls to a higher level.
- For use with an RCA equipped stereo(standard output of 500 mV ), set to the NORMAL position. For use with an RCA equipped Pioneer stereo, with maximum output of 4 V or more, adjust level to match that of the stereo output.
- For use with an RCA equipped stereo with output of 4 V, set to the H position.
- If you hear too much noise when using the speaker input terminals, turn the gain control to higher level.
3. LPF (low-pass filter) cut off frequency control
You can select a cut off frequency from 40 Hz to 240 Hz.
4. SUBSONIC FILTER Switch
When turned ON, frequencies of 30 Hz and below are cut.
Setting gain properly
- Protective function included to prevent malfunction of the unit and/or speakers due to excessive output, improper use or improper connection.
- When outputting high volume sound etc.,this function cuts off the output for a few seconds as a normal function, but output is restored when the volume of the head unit is turned down.
- A cut in sound output may indicate improper setting of the gain control. To ensure continuous sound output with the head unit at a high volume, set amplifier gain control to a level appropriate for the preout maximum output level of the head unit, so that volume can remain unchanged and to control excess output.
- Despite correct volume and gain settings,the unit sound still cuts out periodically. In such cases, please contact the nearest authorized Pioneer Service Station.
Gain control of this unit
Preout level: 2 V ( Standard: 500 mV )
Preout level: 4 V
Above illustration shows NORMAL gain setting.
Setting the unit
Relationship between amplifier gain and head unit output power
If amplifier gain is raised improperly, this will simply increase distortion, with little increase in power.
Signal waveform when outputting at high volume using amplifier gain control
If the signal waveform is distorted due to high output, even if the amplifier gain is raised, the output power will change only slightly.
