Do I need a CL-SSI to sum multiple channels?
No, the FiX™ 82 has built in channel summing with automated level adjustments.
Does the FiX™ 82 allow manual adjustments to the signal?:
Yes. You can apply 10 bands of user-defined Graphic EQ to each output signal. You can also reverse polarity on any input to compensate for any wiring errors. You can also mute any inputs for troubleshooting and calibration optimization. These adjustments can be done using the TüN™ 2.0 Software on a laptop as long as the firmware update procedure has been done.
How do I connect a 4-channel amplifier or multiple amplifiers to the 2-channel output?:
Read our article on Connecting Amplifiers, for more information.
Where do I find the wiring schematics for my vehicle?:
To find the proper wires to connect the FiX™ 82 to, it is recommended to acquire a vehicle wiring diagram. Even with the diagram it’s highly recommended to test all wires. Read for more info on Locating and Testing Wires.
Do I Need to Use the FiX-LSA-4?:
Only if the factory amplifier demonstrates "load sensing" behavior. This type of behavior may include the amplifier muting, distortion, or poor sound quality, especially in the upper frequency range. If muted, meter the amplifier outputs to verify that there is no signal before installing the FiX-LSA-4. Read more about the FiX-LSA-4 here.
Can I Bypass the EQ?:
Yes. Press the Bypass EQ/Calibrate Button for one (1) second. The Calibration Status LED’s will alternate Green/Amber as verification. Bypass EQ mode will last for 5 minutes or until the button is pressed again. You can also bypass in the TüN™2.0 software by clicking bypass for each individual output or by clicking "Bypass All" which bypasses calibration for both outputs.
Why are the Signal Status LED’s flickering Red?:
Input clipping is present. Turn down the volume at your OEM source unit.
When using the hands free system in my vehicle, why are people on the other end complaining about hearing an echo?:
Activate Handsfree Mode by pressing in the DRC-100 knob (optional).
Do I need to use all outputs of my factory source unit or amplifier?
No. To give FiX™ the best chance to calibrate use as few inputs as possible to make a full-range signal. Avoid using center-channel speakers and if using a FiX™ 82, do not use rear speaker signal with the front signal. It is not uncommon to only need one pair of inputs for calibration.
