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, without 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 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 motorized vehicle; the use of headphones may create a traffic hazard and is illegal in many areas.

About This Product

Setting the unit

What’s what

PIONEER GM-D8601 500W Mono Class D AMP 1

PIONEER GM-D8601 500W Mono Class D AMP 2

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

  1. 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 output remains low, even when the car stereo volume is turned up, turn controls to a lower level. If distortion occurs when the car stereo volume is turned up, turn these controls to a higher level. For use with an RCA-equipped car stereo (standard output of 500 mV), set to the NORMAL position. For use with an RCA-equipped Pioneer car stereo, with a maximum output of 4 V or more, adjust the level to match that of the car stereo output. For use with an RCA-equipped car stereo with an 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 a 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. BASS BOOST REMOTE (bass boost level remote control) jack
    By connecting the Bass boost level remote control to the jack on the main unit, you will be able to select a bass boost level from 0 dB to 18 dB. For instructions on connecting the bass boost remote control to the amplifier, see the Connection diagram on page 7.

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 the 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 a continuous sound output with the head unit at a high volume, set the amplifier gain control to a level appropriate for the preset maximum output level of the head unit, so that volume can remain unchanged and 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.

CAUTION

  • Never shorten any wires, the protection circuit may malfunction.
  • Never wire the speaker negative cable directly to the ground.
  • Never band together multiple speaker’s negative cables.
  • If the system remote control wire of the amplifier is connected to the power terminal via the ignition switch (12 V DC), the amplifier will remain on with the ignition whether the car stereo is on or off, which may exhaust the battery if the engine is at rest or idling.
  • Install and route the separately sold battery wire as far as possible from the speaker wires. Install and route the separately sold battery wire, ground wire, speaker wires, and the amplifier as far away as possible from the antenna, antenna cable, and tuner.

Connecting the speakers
This amplifier can be connected to two speakers in parallel. Connect the speaker leads to suit the mode according to the figure shown below.

Precautions for parallel connection

  • When wiring two speakers in parallel, make sure that the synthetic impedance is from 1 W to 8 W to prevent the amplifier from catching fire, generating smoke, and/or being damaged.
  • When connected in parallel with the synthetic impedance of less than 1 W, as a normal function, this amplifier may automatically be set on mute if outputting high-volume sound. Turn down the volume until the mute function is canceled.
