POWER AMPLIFIER OWNER'S MANUAL
1. Gain Controls – These controls are used to match the input sensitivity of the amplifier to the particu-
Input Panel Layout
lar source unit that you are using. The controls are factory set to 1Vrms. Note: The separate gain control for
front and rear channels.
2. RCA Input Jacks – These RCA input jacks are for use with source units that have RCA or Line Level
Outputs. An independent set of jacks are provided for front and rear stereo inputs. A source unit with a
minimum level of 200mV is required for proper operation. The use of high quality twisted pair cables is rec-
ommended to decrease the possibility of radiated noise entering the system.
3. Input Select 2CH/4CH – This switch, is used to match the amplifier's input to the source unit's output
so all four channels of the amplifier are driven. If your source unit has 2 outputs (a left and right) connect them
to the amplifier's front channel inputs, and place the input select switch in the 2CH position. If your source unit
has 4 outputs, (left front, left rear, and right front, right rear) connect them to the amplifier inputs and place the
input select switch in the 4CH position. In the 4CH position, the fader on your source unit will operate.
4. Frequency Control – This control is continuously adjustable from 40Hz through 200Hz. Factory setting
is at 40Hz.
5. Crossover Select – This switch determines what type of signal comes out of the amp. If you select high
pass, the crossover slope is 12dB/stereo. If you select low pass, your crossover slope will be 24dB/mono.
Available crossover frequencies are 40-200Hz.
6. Thunder EQ – This equalization circuit is used to enhance the low frequency response of the vehicle's inte-
rior. With up to 18 dB of boost and centered at 40Hz, the Bass EQ can be adjusted to meet your own personal taste.
7. RCA Output Jacks and Switch – These RCA outputs allow for a signal to be sent to other amplifiers
in a daisy-chain configuration.. You can select whether the signal should be high pass , low pass or full
range. In low pass mode, the RCA outputs allow for multiple bass amplifiers to be level controlled using one
EBC. The RCA output jacks provide a line level full-range summed output of the Right Front/Right Rear and
Left Front/Left Rear input signals.
