1. Front Input: This is the default input. If you are using one input (2 CH.) connect
your RCAs here.
2. Rear Input: Use the rear inputs for 4-channel operation. In this configuration you
can have faded front and rear front your hear unit.
3. Front Output: Front output in name only. If you're using the IDX in 3-Way this will
be your High Pass x-over. This is a High Pass only crossover.
4. Rear Output: The rear output can be set as High Pass, Low Pass or Band Pass.
To use the Band Pass mode you will need to set both High Pass and Low Pass
switches on top of the unit. With both turned on the output will switch to Band Pass.
Note: For this to work the High Pass will have to be set at a lower frequency then the
Low Pass. The Low Pass will filter out the high frequencies above the Band Pass.
The High Pass will filter out the low frequencies below the Band Pass. Confusing?
Look at the little lines printed below the controls. This will help give you a good
mental picture of what's happening.
5. Sub Output: The Sub Output gets its signal by combining the front and rear
inputs. If you're using the 2 Channel input option, your entire signal will come from
the Front Channel input.
6. Power Connector: 12 Volt +, Remote and Ground. We recommend using a
dedicated 12 Volt+ from the battery and a fresh ground. Remember this Crossover
has an 8-volt output. It takes a good amount of current to run.
7. Input Mode Switch: Select between 2 Channel or 4 Channel input. When in 2
Channel Mode the IDX will turn off the Rear Channel input and only except input from
the Front input to drive all the output channels.
8. Front Crossover Switch: High Pass or Full Range. Turns the crossover on or off.
9. Rear Hi Pass Switch: Turns on the rear High Pass. When you use this with the
Rear Low Pass the output becomes a Band Pass.
10. Rear Low Pass Switch: Same as above.
11. Sub Sonic Filter Switch: The IDX is equipped with a variable Sub Sonic Filter.
12. Sub X-Over Slope Switch: 12 or 24dB
13. Front X-Over X10 Switch: It is impossible to accurately adjust a crossover with a
frequency range from 15Hz to 5000Hz. Even the tiniest turn would make a huge
change. For this reason we have added a X10 or 10 times switch. When this switch
is activated the frequency will be 10 Times that marked on the face. 50Hz becomes
500Hz. 500Hz becomes 5000Hz.

14. Front X-Over Gain: Each crossover has its own gain. This will make up front
tuning much easier. You will only need to make basic adjustments to your amp gains.
15. Front Frequency Control: 15Hz to 500Hz (150Hz to 5000Hz in X10 mode). This
should cover most speaker combinations.
16. Clip and Power Lights: To ease tuning the clip lights will begin to flash just
before the output clips. This will help insure the amps receive a clean unclipped,
undistorted signal.
17. Rear High Pass X10 Switch: Same as the Front X10 Switch.
18. Rear High Pass Control: Controls the High Pass Frequency. It is also use to
remove the low frequencies when in Band Pass.
19. Rear X-Over Gain: Same as the front Gain.
20. Rear Low Pass Control: Controls the Low Pass Frequency. It is also use to
remove the high frequencies when in Band Pass.
21. Rear Low Pass X10 Switch: Same as Rear High Pass X10 but for the Low Pass
control.
22. Sub Sonic Filter Control: Removes the lowest frequencies from the bass signal.
These frequencies are the hardest to reproduce by an amp. Rarely can they even be
heard by the human ear. In some cases, when you use a ported box, the woofers can
be damaged by frequencies below the port tuning frequency. These are just 2
reasons to use a Sub Sonic Filter.
23. Sub X-Over Gain: This is the one control most likely to be turned up all the way.
Don't worry, the clip light will tell you when you are getting into trouble.
24. Sub Frequency Control: Unlike the other frequency controls, this one does not
have a X10 switch.
25. Phase Shift Control: "Timing is everything". I a typical install the mid bass
speakers are in the front of the car between 3 to 5 feet from you ear. The sub woofer
is all the way in the back, 9 to 12 feet way. Sometimes more. The Phase Shift can be
used to compensate for this difference in distance by causing the sound from both
speakers to arrive at your ear at the same time. This can really help bring the bass up
front making the system sound more like a live performance.
