Setting The Unit; Connecting The Unit - Pioneer PRS D3000SPL Owner's Manual

Setting the Unit

Bass Boost Frequency Control
You can select a bass boost frequency
from 40 to 120 Hz with the bass boost
control.
Gain Control
If the sound level is too low, even when
the volume of the car stereo used along
with this power amplifier is turned up,
turn gain control on the front of the
power amplifier clockwise. If the sound
distorts when the volume is turned up,
turn the gain control counter-clockwise.
• When using with an RCA equipped car
stereo (standard output of 500 mV), set
to the NORMAL position. When using
with an RCA equipped Pioneer car
stereo with max. output of 4 V or
more, adjust level to match the car
stereo output level.
• For synced amplifier's gain control,
see the "Setting the Gain for Synced
Amplifier" section.
MODE SELECT Switch
You can select amplifier's sync mode
from MASTER, SYNC and SYNC INV.
For the position of the MODE SELECT
switch, see the "Connecting the Speaker
Wires" section.
Bass Boost Level Control
Bass boost level control can boost the
level around the frequency selected by
the bass boost frequency control from 0
to 12 dB.
Cut Off Frequency Control for LPF
You can select a cut off frequency from
40 to 240 Hz.
Power Indicator
The power indicator lights when the
power is switched on.
Subsonic Select Switch
The subsonic filter cuts inaudible fre-
quencies below 20 Hz to eliminate
unwanted vibrations and minimize
power loss.

nal can be connected to the auto-antenna relay control terminal. If the car
stereo does not have a system remote control terminal, connect the male ter-
minal to the power terminal through the ignition switch.
