FRONT PANEL CONNECTIONS/CONTROLS
1.RCA Input Jacks - Accepts line level outputs from head units or signal processors at voltages between 150mV and 7.5 volts.
2.RCA Line Output Jacks - These pass through RCA jacks can be used to send the input signal to a second amplifier.
3.Slave/Master Switch (D1200/D2400 only) - Controls whether the amplifier is a slave or master when connected in combined amplifier configurations. (Refer to the Combined Amplifiers section of this guide.)
4.Gain Control - Controls the ampli- fier’s sensitivity and is used to match the input level of the ampli- fier to the output level of the signal source.
5.Subsonic Switch - The subsonic filter attenuates frequencies below 30Hz by 24dB per octave.
6.Bass EQ Switch - Adds 8dB of bass boost to the subwoofer when selected.
7.Remote - Controls the subwoofer amplifier gain, from a remote loca- tion 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.
8.LPF Control - Controls low pass filter cutoff from 30Hz to 250Hz.
9.Phase Switch - 0° or 180° selec- table for switching the phase output to the woofer.
10.LED/FAN Connector - Allows connec- tion of an optional LED light bar or optional cooling fan for the amplifier.
11.Status LED - Will illuminate GREEN to indicate the amplifier is on and operating normally, and will be illu- minated RED if the amplifier shuts down due to short circuit, DC offset, or overheating detected by on- board protection circuitry.
