ARC Audio IDX Music Mixer User Manual


 
1. Front Output: Simply connect to the amplifier driving the front speakers. This is a full
range output so if you plan to run it hard you should use a crossover at this point.
2. Rear Output: Just like it sounds, this is connected to the rear amp.
3. Input: Main Input should be a full range signal from the head unit. If you are using the
Sub Direct Input the signal could be crossover but the EQ will function better if you feed it a
full range signal.
4. Sub "Direct Input": This is where things get a little tricky. If your deck has a sub woofer
output with any kind of advanced feature you may wish to use the Sub Direct Input. This
input bypasses the EQ section and feeds signal to the Master Volume and to the Sub Out. In
this way all you features still work
.
5. Sub Output: Connect to your Sub woofer amp or amps.
6. Power Connector: 12 Volt +, Remote and Ground. We recommend using a dedicated 12
Volt+ from the battery and a fresh ground. Remember this EQ has an 8-volt output. It takes
a good amount of current to run.
7. Input Gain: Most modern head units have between 4 and 8-volt outputs. With this input
level the XEQ gains should be left at +0dB. Only use the +6dB and +12dB in extreme
conditions were you just can't get enough gain from the head unit.
8. Sub Input Gain: I know it's tempting to add a bit more gain to the Sub input but this isn't
the place to do it. I most cases it should match the input gain
.
9. Sub Crossover Switch: The XEQ has a 12dB Sub woofer crossover. This feature can be
bypassed by setting the switch to "Full". Warning: The Sub Out will now be Full Range.
10. Sub "Direct Input" Switch: Bypasses the EQ and routes the sub signal directly to the
"Sub Out" allowing the use of the advanced features in your head unit.
11. Sub EQ Bypass: With this switch it is possible to bypass the EQ for the sub out. This
could be helpful for tuning your mid bass woofers without making any changes to the sub
woofers. This switch must be in "Bypass" mode if you are using the "Sub Direct In".
12. Sub Frequency Control: Be sure to make your final adjustments to the Sub crossover
before you mount the unit into the dash of your car. You will need to complete your tuning
first.
13. Master Volume: Controls all Output including the "Sub Out". It is very handy to have
one volume under your thumb for "Fast" and easy control.
14. Clip Indicator: Use these as a guide. If the clip lights are flashing you're in the 'Danger
Zone" If the system can't get loud without the Clip lights flashing, reevaluate your gain
setting.
15. EQ Frequency Controls: If you know what an EQ does, you most likely know what
these do. We've crammed 7 bands into the XEQ, for ultimate control at your fingertips.
16. Fader: Full front/rear control to keep the people in the back seat happy.
17. Sub Volume: Or Sub Out level, gives you total control of the Sub Gain at any time.
