your hearing!
• Keep all electronics away from moisture, dust, extreme heat or extreme vibrations.

Electronic connections
Connect 12V DC from a constant battery source to a +12V slip-on spade terminal
11
and install a one (1) amp fuse in line.
Connect the SX7’s GROUND to a good chassis ground, near where the unit
2
is mounted, or to the case of the head unit.
Connect the SX7’s REMOTE TURN-ON lead to the remote turn-on lead of the
3
head unit, and install a 1/2 amp fuse in line. (A relay should be used if turning on more than one component, such as EQ’s, crossovers or amplifiers.)
Connect stereo RCA cables from the head unit’s left and right front outputs
4
to the left and right inputs of the SX7.
Connect stereo RCA cables from the left and right Low, Mid and High outputs
5
of the SX7’s to the corresponding left and right inputs of your amplifiers.
Turn the unit on, and adjust the input gain on the SX7 to match the output
6
of the head unit (1/2, or at center position, is about 1 V). Be careful not to overdrive the input of your amplifier(s) or signal processor(s). Use clip detectors to adjust output.
Adjust each of the 7 rotary equalizer controls +/- 12 dB to acheive the desired
7
sound characteristics.

Used to turn power on and off to the SX7.
This LED is illuminated when the unit is properly powered, grounded and the remote power has been turned on.
The frequency control adjusts the range of the signal delivered to the Sub channel. The gain control adjusts the level of that signal.
This is used to reverse the phase of the subwoofer channel to the other channels in the system for proper signal alignment.
The frequency control adjusts the range of the signal delivered to the Mids channel. The gain control adjusts the level of that signal.
The frequency control adjusts the range of the signal delivered to the Highs channel The gain control adjusts the level of that signal.
RCA cables are used to connect the input signal from a head unit or other source.
Connect to power source as follows:
+12v: Connect a red wire of at least 12 gauge to
the car battery or other power source.
GROUND: Connect a black wire of at least 12 gauge to car chassis for ground connection.
