FRONT PANEL CONNECTIONS

1.RCA Input Jacks - Accepts line level outputs from head units or signal processors at voltages between 150mV and 8 volts.

2.RCA Sync Out/ Slave In Jack

Sync Out - This RCA jack sends a Synced or in-phase gain matched output signal to a slave amplifier when connected in the Parallel Synced Gain combination. It is a Synced output when the slave/master switch is in the MASTER position only.

Slave In - This RCA jack accepts input from a master amplifier. It is for use in the Parallel Synced Gain and External Synced Bridged combi- nations. It is a slave input when the slave/master control switch is in the SLAVE position only.

3.RCA Bridge Output Jack - This output sends an out-of-phase signal to a slave amplifier when connected in the External Synced Bridged combi- nation. (Refer to the Combined Amplifiers section of this guide)

4.Slave/Master Switch - Controls whether the amplifier is a slave or master when connected in combined amplifier configurations. (Refer to the Combined Amplifiers section of this guide.)

5.Remote Sub Level Control - Controls the subwoofer amplifier gain controls from a remote location for ease of adjustment during listening.

Warning: DO NOT connect a level control knob from other manufacturers to the Remote Sub Level Control of any Directed amplifier. Even though the connectors fit properly, the control knob and connector pin positions may be different and the amplifier will be damaged.
