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.
