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.Phase Switch - Set the phase switches of all synced MASTER amps to 0°. Set the phase switches of all synced SLAVE amps to 180°. The master and slave amps must be set to the opposite phase mode in order for External Synced Bridged operation to work.
4.In order 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 jacks of the Master amplifier and the INPUT RCA jack of the Slave ampli- fier as shown in Figure 6.
6.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.
WARNING: The amplifier’s gain control is bypassed completely 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.
