OVERDRIVE Series Class D Monoblock Amplifier
SR1-3500D / SR1-5000D / SR1-7500D
Features & Functions:
Power Connection:
For your convenience high current barrier strip terminals are provided which
allows the use of heavy gauge terminals and wire without splicing.
B+/+12V. Connect the +12V pole of the battery.
GND. Connect the chassis ground of auto.
REM. Connect to the remote turn-on lead of your head unit.
Note:
Improper wiring connections can seriously damage amplifiers, accessories,
or speakers, please follow instructions carefully.
Disconnect the battery positive (+) before making any power connections to the
amplifier.
Make sure all connections are clean and secure and use grommets when going
through the firewall and other metal bodywork.
Always use the proper size fusing, with a fuse at the battery and the
amplifier. (not supplied)
**Input Connection:
**
Connect the pre-amp( low-level) outputs from your source unit or crossover to
the RCA jacks labeled “input” on the amplifier. Be sure to route all signal
cables away from power lines and use high-quality RCA cables to insure good
signal transfer and to avoid noise from entering the system.
In the Mono mode, connect the left and right RCA plugs from the source
unit to their appropriate input jacks.
In the Bridged mode, Monoblocks Together for Double Power
**Output connection:
**
Again, high current barrier strip terminals are provided for connection to the
loudspeaker system.
Connect the subwoofer speaker+ lead to the + terminal and the subwoofer
soaker-lead to the terminal.
Note: Mono mode is designed for 1-8 ohm loads. If connecting two
subwoofer speakers, the unit will not support a 1-ohm load.
**Connect two Subwoofer Systems:
**
Connect the two pairs of output terminals to corresponding subwoofer speakers:
Connect one subwoofer System :
2nd speakers connection
TROUBLESHOOTING
No Audio
- Low or no remote turn-on voltage: check remote connections at the amplifier and source unit.
- Blown amplifier fuse: replace with a new fast-blow fuse (same rating).
- Power wires not connected: check battery and ground wiring at the amplifier and check the battery connections.
- Speaker leads shorted: check speaker continuity to the ground; it should not show common ground.
- Speakers not connected or are blown: check speaker connections at the amplifier; measure coil impedance.
Distorted audio
- Gain is not properly set or the speaker cones are damaged.
- Review the instructions for setting the gain. Inspect each speaker cone for signs of damage, such as a frozen cone, burning smell, etc.
