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 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.

Before you start

Section

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.

sociated with accessories sold with the product may expose you to chemicals listed on proposition 65 known to the State of California and other governmental entities to cause cancer and birth defect or other reproductive harm. Wash hands after handling.

! This unit is for vehicles with a 12 V battery and

negative grounding. Before installing in recreational vehicles, trucks or buses, check the battery voltage.

! When installing this unit, make sure to con-

nect the ground wire first. Ensure that the ground wire is properly connected to metal parts of the car’s body. The ground wire of the one of this unit must be connected to the car separately with different screws. If the screw for the ground wire loosens or falls out, it could result in fire, generation of smoke or malfunction.

! Be sure to install the fuse to the battery wire. ! Always use a fuse of the rating prescribed.

The use of an improper fuse could result in overheating and smoke, damage to the product and injury, including burns.

! Check the connections of the power supply

and speakers if the fuse of the separately sold battery wire or the amplifier fuse blows. Determine and resolve the cause, then replace the fuse with and identical equivalent.

! Always install the amplifier on a flat surface.

English

Do not install the amplifier on a surface that is not flat or on a surface with a protrusion. Doing so could result in malfunction.

! When installing the amplifier, do not allow

parts such as extra screws to get caught between the amplifier and the automobile. Doing so could cause malfunction.

! Do not allow this unit to come into contact

with liquids. Electrical shock could result. Also, damage to this unit, smoke, and overheating could result from contact with liquids. The surfaces of the amplifier and any attached speakers may also heat up and cause minor burns.

! In the event of any abnormality, the power

supply to the amplifier is cut off to prevent equipment malfunction. If this occurs, switch the system power off and check the power supply and speaker connections. If you are unable to determine the cause, please contact your dealer.

! Always disconnect the negative * terminal of

the battery beforehand to avoid the risk of electric shock or short circuit during installation.

! Do not attempt to disassemble or modify this

unit. Doing so may result in fire, electric shock or other malfunction.

Setting the unit

Section

What’s what

Front side

Rear side

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 FREQ (cut off frequency) control

Cut off frequency selectable from 40 Hz to 500 Hz if the LPF/HPF select switch is set to LPF or HPF.

3 GAIN (gain) control

Adjusting gain controls CHANNEL A (channel A) and CHANNEL B (channel B) helps align the car stereo output to the Pioneer amplifier. Default setting is the NORMAL position. If output remains low, even when the car stereo volume is turned up, turn controls to lower level. If distortion occurs when the car stereo volume is turned up, turn these controls to 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 car stereo

(standard output of 500 mV), set to the NORMAL position. For use with an RCA

3 2

equipped Pioneer car stereo, with maxi-

English

mum output of 4 V or more, adjust level to match that of the car stereo output.

! For use with an RCA equipped car stereo

with output of 4 V, set to the H position.

4 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 con-

nected: Select HPF or OFF. HPF eliminates low range frequency and output high range frequency. OFF outputs the entire frequency range.

5 INPUT SELECT (input select) switch

Select 2CH for two-channel input and 4CH for four–channel input.

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 preout maximum output level of the head unit, so that volume can remain unchanged and to control excess output.

Section

Setting the unit

! 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: 2V (Standard: 500 mV)

Preout level: 4V

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

Signal waveform distorted with high output, if you raise the gain of the amplifier the power changes only slightly.
