5. High pass x-over frequency control - This control is used to select the desired high pass x-over frequency. The
frequency can be adjusted between 40Hz and 800Hz.
6. Frequency multiplier switch for high pass x-over - This switch is used to multiply the selected high pass fre-
quency x10 resulting in a selectable high pass frequency between 400Hz and 8kHz. When this switch is pressed the
selcted high pass x-over frequency is multiplied by 10.
7. Low pass x-over switch - This switch is used to switch on and off the active low pass x-over of the amplifier.
When this switch is pressed the x-over is switched on, when this switch is depressed the x-over is switched off.
8. Low pass x-over frequency control - This control is used to select the desired low pass x-over frequency. The
frequency can be adjusted between 40Hz and 800Hz.
9. Frequency multiplier switch for low pass x-over - This switch is used to multiply the selected low pass frequency
x10 resulting in a selectable low pass frequency between 400Hz and 8kHz. When this switch is pressed the selcted
low pass x-over frequency is multiplied by 10.
** Note: It is also possible to create a band-pass x-over on this amp to drive midrange speakers actively. To create
a band-pass x-over both the high and low pass x-overs need to be switched on. The desired pass band can then
be selected using the high pass frequency control to set the lower x-over point and the low pass frequency control
to set the higher x-over point.**
10. Speaker Terminals – Be sure to observe speaker polarity throughout the system. Failure to wire the speakers
in proper phase could result in a loss of bass response and/or poor overall sound quality. Caution: COUSTIC COM-
PRESSOR amplifiers are not recommended for loads below 2 ohms stereo or 4 ohms bridged.
11. Fuse - For convenience, all COUSTIC COMPRESSOR amplifiers utilize ATC type fuses. For continued protection
in the event that a fuse blows, replace the fuse only with the same value.
Caution : The power fuse on the amp is for protecting the amp against overdrive. To protect the vehicle’s electrical
system, an additional fuse is required within 30cm of the battery on the 12V+ cable.
12. Power Terminal – This is the main power input for the amplifier and must be connected directly to the positive
terminal of the car battery for the amplifier to operate properly. Use caution when running this cable through the
vehicule. Try to avoid running this cable along side the input RCA cables, antenna cabling, or other sensitive equi-
pment as the large amount of current flowing through this cable can induce noise into your system. It is also very
important to have a tight connection to ensure maximum performance. We recommend to use 10mm2 or larger
power wire with the COUSTIC COMPRESSOR C200 amplifier.
13. Remote Terminal – The Amplifier can be turned on by applying 12 volts to this terminal. Typically this voltage is
supplied by a wire from the source unit marked “remote” or “electric antenna”.
14. Ground Terminal – A good quality ground is required for your Amplifier to operate at peak performance. A short
length of cable the same gauge as your power cable should be used to attach the ground terminal directly to the
chassis of the vehicle. Always scrape or sand any painted surfaces to expose bare metal where the ground wire
will attach.
15. Input selection switch 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 (left and right) connect them to
the amplifier’s channel 1 + 2 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 all the amplifier inputs and place the input
select switch in the 4CH position. In the 4CH position, the fader on your source unit will function.
