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 FOLLOWINGGUIDELINES:!

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 area-s.

Setting the unit

What’s what

To adjust the switch, use a flathead screwdriver if needed.

FREQ (cut off frequency) controlCut off frequency selectable from 40 Hz to500 Hz if the LPF/HPF select switch is set toLPForHPF

GAIN (gain) controlAdjusting gain controls CHANNEL A(channel A) and CHANNEL B(channel B) help align the stereo output to the Pioneer amplifier. Default setting is the NORMAL position. 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.!

  • If using only one input plug, set the gain controls for speaker outputs A and B to the same position.
  • 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

LPF (low-pass filter)/HPF (high-pass filter) select switch

Switch the settings based on the connected speaker.!

  • When the Subwoofer is connected: Select LPF. This eliminates high range frequency and outputs low range frequency.!
  • When the full range speaker is connected: Select HPF or OFF.HPF eliminates  low range frequency and output high range frequency. OFF outputs the entire frequency range.

INPUT SELECT (input select)

switch Select 2CH for two-channel input and4CHfor four–channel input.

POWER/PROTECT indicator

The power indicator lights up to indicate power ON.!

  • If something is not normal, the indicator turns red.

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 impro-per 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 pre out 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

Above illustration shows NORMAL gain setting

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
