Directed Electronics A1004 Bass EQ - allows 8dB additional base boost on sub channel D2205

5.Line Out Switch (D2205) - three positions:

sum L/R—left front and rear and right front and rear channels are summed.

sub L+R—set the switch to this position when using an additional D1200 amplifier connected in Parallel mode.

sub 180°—set the switch to this position when using an additional D1200 amplifier connected in External Bridge mode.

6.Gain - controls amplifier sensitivity and is used to match the input level of the amplifier to the output level of the signal source. (front and rear on A1004 and D2205.)

7.Bass EQ - allows 8dB additional bass boost (A802 and A1004).

8.X-Over HPF, Flat, LPF - the HPF attenuates low frequencies and is used with mid-range speakers and tweeters. Full does not attenuate any frequencies and is for full range speaker systems. LPF attenuates high frequencies and is used for subwoofers.

9.X-Over Freq - adjusts the crossover point (50-500Hz) for the on-board active crossover.

10.Remote - optional accessory which allows the level to be adjusted remotely (usually located for control by the vehicle’s driver).

11.Subsonic - the OFF position takes the filter out of the system, the IN position places the the filter into the system (D2205).

12.Sub Gain - subwoofer channel gain adjustment.

13.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.

14.LED/Fan - allows connection of an optional LED light bar or optional cooling fan for the amplifier.

15.LPF - sets high frequency limit of subwoofer channel (D2205).

16.Bass EQ - allows 8dB additional base boost on sub channel (D2205).

17.Sub Input/Line Out - selects RCA jacks (4) (Sub/Line Out) as either Subwoofer Input or Line Output.
