ZACHRY CAR AUDIO CONTROL FUNCTIONS 1. SPEAKERS Connect speakers/subwoofers to these terminals. Be sure to check wire for proper polarity. Never connect the speaker cables to chassis ground. 2. +12 Volt Power Connect this terminal through a FUSE or CIRCUIT BREAKER to the positive terminal of the vehicle battery or the positive terminal of an isolated audio system battery.
11. Hi-pass filter (Full range) This knob controls the frequencies played for the front channels. Low frequencies can be cut out from OFF to 200Hz. At OFF position, none low frequency cut out, that means full pass. 12. X-over mode and frequency Control (Full range) These controls allow control over the frequencies played for the rear channels. There is an option for Low Pass, Full Range or High Pass. In LP or HP mode, the crossover frequency can be tuned from 50Hz to 750Hz by the frequency knob. 13.

Mono amplifier wiring (Multi-woofer load) Zachry K1200D FUSE REMOTE signal Source Unit RCA signal K1200D Digital Car Amplifier *Equivalent parallel woofer load cannot be less than the minimum load rating. The 2 negative terminals are paralleled inside the amplifiers, as are the 2 positive terminals. These are monoblock amplifiers, not multi-channel amplifiers. Minimum load for Zachry K1200D is 1 ohm.
ZACHRY CAR AUDIO CONNECTING THE AMPLIFIER 1. Select cable and fuse according to the following table. 2. Connect the amplifiers ground cable to a close, bare metal part of the frame or chassis. Use a nut and bolt, NOT a screw! The ground cable must be at least the same size as the +12volt cable. 3. Connect the remote terminal to remote output of the head unit using 16 gauge (or heavier) wire. 4.

ZACHRY CAR AUDIO TROUBLE SHOOTING Symptom Possible Remedy Amplifier will not power up Check to make sure you have a good ground connection. Check that there is battery power on the (+)terminal . Check all fuses, replace if necessary . Make sure that the Protection LED is not illuminated. Protection LED Comes on Check for short circuits on speaker leads. Check the speaker load not beyond the minimum load. Remove speaker lead, and reset the amplifier.
