Details
Regulated 12VDC power supply required to power the module. When mounted externally
connect the amplifier's trigger wire to AMP Vcc+ . When connected internally, connect either the
amplifier's trigger wire or the amplifier's positive power supply rail to AMP Vcc+ and amplifiers
Ground to Amp GND. If all these are not possible connect the modules own power supply
+12VDC using a jumper wire to AMP Vcc+. Delay can be adjusted from 500ms to 1second by
changing capacitor C5 to twice its uF. Connect your amplifier positive output to Amp OUT and
amplifier negative output to AMP GND. Connect your speaker positive to SPEAKER and negative
to SPKR Gnd.
For bridged amplifiers use two modules as the amplifiers negative output terminal is also hot.
Do not connect the amplifier's negative output terminal to the module's AMP GND in a bridged
amplifier.
The module will give you long term speaker protection service if used correctly. There are no
special requirements for earthing the module and can be earthed as per your procedure in
relation to chassis.
