Introduction Congratulations! You have just chosen the premium in car audio equipment. ZAPCO has well established its place as the technological leader in the car audio industry. Because of this, you can rest assured that you have the best car audio components in the world.
The cable supplied with your SEQ is comprised of seven wires. These seven wires are terminated on one end in a connector designed to be inserted into the back of the SEQ. The other wire ends have been left unterminated.
ADDITIONAL GROUND CONNECTIONS: To ensure proper system grounding the following additional connections must be made. RCA Shields & SEQ case must be connected to case of source unit. RCA Shields - Signal Ground from amplifier inputs (connect wire from RCA Shields @ amplifier input to case of source unit)*...
Operation and Calibration A. Input gain controls provide adjustable gain of 6dB to 26dB. B. Input clipping detector flashes whenever input signal is within +/- 1dB of clipping (super-bright LED). C. Volume control: high-quality conductive plastic potentiometer. D. Output clipping detector: indicates the onset of output clipping. E.

If the input gain adjustment is set too high, the internal circuitry of the SEQ and/or system amplifiers may distort. There are two clipping indicators, one for input stage clipping and one for output clipping.
1/4” socket-head screws and nylon shoulder washers. Once the equalizer is swiveled to the desired angle (the SEQ may be mounted with the bracket either above or below it) tighten the socket-head screws using a 3/16” allen wrench.
Once we issue you a return authorization number, please write it in a highly visible area on the package. Zapco will not accept any packages that do not have a valid return authorization number clearly marked on the outside of the package.
