GAIN (6V ~ 0.2V)
Matching the output voltage of the headunit's RCA
line-outs to OKUR amplifiers' input section.
SUBSONIC FILTER (10Hz ~ 50Hz @ 24dB/Oct)
Control the high Pass point for the speaker outputs
to eliminate extreme low frequencies that can
damage your speakers.
BASS BOOST (0~9dB @ 45Hz)
It boosts the bass 0 ~ 9dB
REMOTE LEVEL CONTROL PORT
This port is for connecting remote gain level control
LOW PASS FILTER (35Hz ~ 10KHz @ 24dB/Oct )
Controls the low pass point for the speaker outputs.
PHASE (0 ~ 180 degree )
It controls phase from 0 ~ 180 degree.
3. INSTALLATION
In case you install the amplifier by yourself, please read owner's manual very carefully before your installation
Please take all steps into consideration or, you can have DB Drive or DB Research's authorized dealer to check
installation and set your car audio systems.
3-1. MOUNTING PREPARATION
Disconnect the negative ( - ) battery cable before mounting your amplifier or making any connections. Check
the battery and alternator ground ( - ) connections. Make sure they are properly connected and free of
corrosion before selecting a mounting location. Please take some concerns into consideration with cooling
efficiency and safety.
3-2. MOUNTING PREPARATION
The A7PRO2.5K amplifier uses a specially designed heat radiation heatsink to avoid excessive heat
from circuitry. But for better heat dissipation, it is good to find the mounting location where you can install
vertically with the heatsink fins and better air flow around heatsink.
For the safety, You have to find a dry and well ventilated location and make sure any cables and drilling car
equipment are not interfere with mounting location. Be sure the mounting location and drilling of pilot cables
will not present a harzard to any cables, control cables, fuel lines, fuel tanks, hydraulic lines or other vehicle
systems or components.
3-3. +12V, GND, REM CONNECTION.
12V ( POWER CONNECTION )
Before mounting amplifier, disconnect the negative ( - ) wire from battery to protect any accidential damage to
amplifier and audio system. A7PRO2.5K use minimum 4 gauge cables.
Connect the power cables to power terminal labeled as +12V. A7PRO2.5K is not equipped with fuses so you
need to install external fuses.
In order to install external fuses, connect one end of fuse holder to the power cable and the other end of
fuse holder to positive battery within 18in of the same cable gauge. This fuse location will protect the system
and the vehicle against the possibility of a short circuit in the power cable.
Be sure to use fuses and fuse holders adequate for the current draw application.
+12V (POWER CONNECTION)
This must be connected to the fuse positive terminal
(+12V) of the battery.
Recommenede wire is 4 gauge or thicker
Check the battery voltage.
GND ( GROUND CONNECTION )
It is connected to the Negative or ground cables of
the vehicle.
Recommenede wire is 4 gauge or thicker
REM (REMOTE)
It is connected to switched +12V with a trigger cable
coming from the head unit.
SPEAKER OUTPUTS
It connects amplifier's terminal to subwoofer
speakers.
Minimum speaker wire is 12 gauge.
Minimum impedance is 1 ohm for single unit.
Linked connection's minimum impedance is 2 ohm.
