EXTERNAL SYNCED BRIDGED CONNECTIONS/SETTINGS

1.Input Signal - Connect these RCA jacks as described in the Front Panel Connection 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 auto- matically set the I/O RCA jack configuration according to each amplifiers slave or master designa- tion.

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.

3.Remote Sub Level Control - Connect the Remote Sub Level control to the master amplifier only. The master amplifier gain control is used to set the overall gain for both amplifiers, and then the Remote Sub Level control can adjust the gain of both amplifiers.

4.Signal Connection - Connect an RCA cable between the BRIDGE OUT RCA jack of the Master amplifier and the SLAVE IN RCA jack of the Slave amplifier as shown in Figure 6.

5.Subwoofer Speaker Connection - In this amplifier combination the Subwoofer speaker terminals of both amplifiers drive common subwoofer(s). Use the following speaker connection diagram when connecting the subwoofers to the amplifiers. Connect the amplifiers speaker terminals to any combina- tion of one or more subwoofers that results in a nominal impedance between 2 and 4 ohms. DO NOT connect loads of less than 2 ohms when connecting to amplifiers in the External Synced Bridged combi- nation.

WARNING: Two wires of 12AWG minimum must be connected between the negative sub out termi- nals of the master and slave amplifiers.
