NOTE:
For best results, connect both negative speaker terminals on the master amp to both
negative terminals on the slave amp using at least 12 AWG cable.
FUNCTIONS
1.
LINE IN (RCA)
The RCA style input jacks are for use with source units that have RCA line level outputs. A
source unit with a minimum of 250mV is required for proper operation.
However, this input will accept levels up to 6Vrms.
2.
High Level Input
If you are installing by using a high level . you do not need to connect to the remote.
To hear a better sound quality, you must connect the high-level ground wire to the headunit ground.
3.
Phase Shift
Phase Shift Switch ( 0 or 180 degrees): Allows you do change the phase of your subwoofer from 0
to 180 degrees to compensate for timing differences between drivers.
4.
Thru-Out
The LINE OUT allows you to build multiple amplifiers systems without having to use splitter cords
to distribute the signal. Now it is simply a matter of bringing one set of RCAS into the fist amplifier,
then using the line out RCA jacks as the feed to the next amplifier.
5.
Bridgeable Mode
Master Mode
For bridging into a single speaker load, to do this you must utilize the MASTER/SLAVE switch
settings. For the MASTER amplifier, set the switch setting to MASTER. This will route the signal
through RCA to the other (slave) amplifier. On the slave amplifier set this switch to the SLAVE
position. Refer to Auxiliary Output Configuration section of this guide. Set the PHASE switch on
the slave amp, move the phase switch from 0 to 180, exactly opposite of the master amp.
Refer to the Phase Switches section of this guide.
Slave Mode
On the slave amplifier be sure to turn off all crossovers. For the speaker connections, connect
the positive (+) speaker lead from the speaker to the positive (+) speaker terminal of the master
amplifier. On the negative (-) speaker connection, take the negative (-) speaker terminal of the
master amplifier and connect it directly to the negative (-) speaker terminal of the slave
amplifier. The remaining positive (+) speaker terminal of the slave amplifier must be connected
to the negative (-) speaker lead from the speaker. The impedance of the speaker must not
exceed 2Ω. See diagram below.
