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 blar-

ing 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 dis-

tortion.

!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.

Before you start

If you experience problems

Should this product fail to operate properly,

please contact your dealer or nearest author-

ized Pioneer Service Station.

To adjust the switch, use a flathead screwdri-

ver if needed.

1 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.

! Bass boost level setting applies only to

CHANNEL B (channel B) output.

! For instruction of connecting the bass

boost remote control to the amplifier, see

the .Connection diagram

3 GAIN (gain) control

Adjusting gain controls (chan-CHANNEL A

nel A) and (channel B) helpsCHANNEL B

align the car stereo output to the Pioneer

amplifier. Default setting is the NORMAL

position.

Before you start Setting the unit

If the output remains low, even when the car

stereo volume is turned up, turn the con-

trols to a lower level. If distortion occurs

when the car 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 car stereo

(standard output of 500 mV), set to the

NORMAL position. For use with an RCA

equipped Pioneer car stereo, with maxi-

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 position.H

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.

!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 gain set-NORMAL

ting.

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.

Setting the unit

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.
