FRONT PANEL CONNECTIONS/CONTROLS 200/2 - 300/2

1.High Level Input Connector - Accepts 1v to 10v input from the headunit’s speaker output.

2.RCA Output Jacks - These pass through RCA jacks can be used to send the input signal to a second amplifier.

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

4.Input Gain Adjustment - Controls amplifier sensitivity and is used to match the input level of the ampli- fier to the output level of the signal source.

5.Crossover Selection Switch - Controls the type of filter for the on-

board active crossover. FLAT does not attenuate any frequencies and is for full-range speaker systems. HPF attenuates low frequencies and is used for mid-range speakers and tweeters. LPF attenuates high frequencies and is used for subwoofers speakers.

6.Bass EQ Switch - Adds an additional 8 db of boost to the speaker output when on.

7.Status LED - Will light GREEN to indicate the amplifier is on and operating normally, and will be off if the amplifier shuts down due to short circuit, DC offset, or over- heating detected by on-board protection circuitry.
