1. PRODUCT DESCRIPTION & WARNINGS

DSP-88R is a digital signal processor essential to maximize the acoustic performance of your car audio sys­tem. It consists of a 32-bit DSP processor and 24-bit AD and DA converters. It can connect to any factory
system, even in vehicles featuring an integrated audio processor, since, thanks to the de-equalization func­tion, DSP-88R will send back a linear signal.

It features 7 signal inputs: 4 Hi-Level, 1 Aux Stereo, 1 Phone and provides 5 PRE OUT analog outputs. Each
output channel has a 31-band equalizer available. It also features a 66-frequency electronic crossover as
well as BUTTERWORTH or LINKWITZ filters with 6-24 dB slopes and a digital time delay line. The user can select
adjustments that allow him or her to interact with DSP-88R through the remote control device.

WARNING: A PC provided with Windows XP, Windows Vista or Windows 7 operating system, 1.5 GHz mini-

mum processor speed, 1 GB RAM minimum memory and a graphics card with a minimum resolution of 1024
x 600 pixels are required to install the software and setup the.

2- Before connecting DSP-88R, carefully read this manual. Improper connections may cause damage to the
DSP-88R or to the speakers in the car audio system.

4.1 Primary Wire Harness
HIGH LEVEL / SPEAKER LEVEL INPUTS
The primary wire harness includes appropriately color-coded 4-channel hi-level signal inputs to connect
speaker level signal from the head unit. If the head unit low-level RCA outputs are equal or greater than
2V RMS, you can connect it to the high-level inputs. Use the input gain control to appropriately match the
input sensitivity to the head unit output level.

POWER SUPPLY CONNECTIONS
Connect constant 12V+ power to the yellow 12V+ wire and ground to the black GND wire. Be sure the po­larity is as indicated on the wire. A misconnection may result in damage to DSP-88R. After applying power,
wait at least 10 seconds before turning on.

REMOTE IN / OUT CONNECTIONS
Connect the amplifier turn-on of the head unit or switched/ACC 12V power to the red REM IN wires. Con­nect the blue REM OUT wire to the remote turn-on terminal of the amplifier and/or other devices in the
system. REM OUT features a 2 second delay to eliminate noise pops.

any amplifiers are turned on. The head units amplifier turn-on must be connected to REM IN, and REM OUT
should be connected to the remote turn-on terminal of the amplifier(s) or other devices in the system.

HANDS-FREE BLUETOOTH MODULE INPUT
The primary wire harness also features connections for a hands free Bluetooth module. Connect the au­dio +/- outputs of the hands-free Bluetooth module to the pink color PHONE +/- wires of the primary wire
harness. Connect the mute trigger output of the hands-free Bluetooth module to the orange color PHONE
MUTE - wire of the primary harness. The mute control is activated when the mute trigger receives ground.
The PHONE MUTE terminal can also be used to enable the AUX input. In this case, the PHONE +/- inputs are
inactive.

DSP-88R must be switched on before

MUTE IN
The outputs of DSP-88R can be muted when starting the engine by connecting the brown MUTE IN wire to
the ignition starter turn-on. The MUTE IN terminal can be used to enable the AUX IN input. In this case the
output mute function, set by default, will be disabled.
