NOTE: The dual (+) and (-) sub-out terminals of the PA400.1, PA600.1 and PA1200.1 are paralleled internally, and the combined load impedance should be taken into consideration when connecting multiple subwoofers.

PARALLEL SYNCED GAIN

CONNECTIONS/SETTINGS

Refer to Figure 5 for wiring details.

1.Input Signal—Connect these RCA jacks as described in the Front PanelConnection section of this guide.

2.SLAVE/MASTER Switch—

•Set the SLAVE/MASTER switch on the master amplifier to the MASTER position.

•Set the SLAVE/MASTER switch on the slave amplifier to the SLAVE position.

•Setting the SLAVE/MASTER switch on both amplifiers will automatically set the I/O RCA jack configuration according to each amplifier’s slave or master designation.

NOTE: One master amplifier can control up to three SLAVE amplifiers in this combination. Multiple identical MASTER/ SLAVE combinations can be added to any given system.

3.Phase Switch—Set the phase switches of all synced amps to the same position (all at 0° or all at 180°).

ENGLISH

4.To Achieve Safe, Optimal Performance—The LPF, Bass EQ, and Subsonic Filter controls on all synced amps must be set to the same position.

5.Signal Connection—Connect an RCA cable between the OUT RCA jack of the master amplifier and the SLAVE IN RCA jack of the slave amplifier as shown

in the Figure 5.

6.Subwoofer Speaker Connection—In this amplifier combination, each amplifier must drive its own separate subwoofer(s). Connect the speaker terminals of each amplifier to any combination of one or more subwoofers that results in nominal impedance between 1 and 4 ohms. Make sure that each amplifier sees the same speaker impedance.

WARNING: The amplifier’s gain control is bypassed com- pletely in SLAVE mode. DO NOT move the MASTER/SLAVE switch to SLAVE position when the amplifier is connected and playing. DO NOT connect any signal source to the amplifier in SLAVE mode that exceeds 200mV.

COMBINING AMPLIFIERS

The Polk 600.1 and 1200.1 subwoofer amplifiers have the capability of connecting two or more amplifiers of the same power rating together in a master/slave combination for increased power with accurate level matching. They are the Parallel Synced Gain and External Synced Bridged combinations.

WARNING: DO NOT attempt to combine amplifiers of different power ratings. These amplifier combinations work correctly only if the MASTER and SLAVE amplifiers are identical models.

PARALLEL SYNCED GAIN

In this MASTER/SLAVE combination the master amplifier pre-amp controls remain active and the slave amplifier pre-amp is bypassed. This allows the master amplifier to control gain, filter, and sub-level on both amplifiers. This combination allows the amplifiers to drive their own separate subwoofer(s) while being synced together via an in-phase audio pre-amp signal from the master amplifier. Wiring connections to the amplifier subwoofer outputs

in this combination should be standard in-phase configura- tions, creating a parallel speaker connection. (Refer to Parallel Synced Gain section of this guide for amplifier and speaker connection diagrams.)

NOTE: One master amplifier can control up to three slave amplifiers in this combination. Multiple identical MASTER/ SLAVE combinations can be added to any given system.

EXTERNAL SYNCED BRIDGED

In this MASTER/SLAVE combination the master amplifier pre-amp controls remain active and the slave amplifier pre-amp is bypassed. This allows the master amplifier to control gain, filter, and sub-level on both amplifiers. This combination allows the amplifiers to drive common sub- woofer loads while being synced together via an out-of- phase audio pre-amp signal from the master amplifier. In this subwoofer wiring configuration the master ampli- fier sends the positive signal to the subwoofer while the slave amplifier sends the negative signal, making an externally bridged speaker connection. (Refer to External Synced Bridged section of this guide for amplifier and speaker connection diagrams.)

NOTE: Amplifiers in this combination can only be connected in matched pairs. Multiple matched pairs may be added

to drive separate subwoofer loads in a given system.

COMBINED AMPLIFIERS

GAIN AND FILTER SETTINGS

NOTE: You MUST set the Subsonic, EQ, and other filter settings on the masteramplifier to the same positions to achieve safe, optimal results. Adjustment guidelines are discussed in the Crossover and Gain Adjustment section of this guide.
