FiX®: Calibration Failure Troubleshooting
If you are seeing any sequence of the Calibration Status LED’s flashing RED, the FiX® 82 or FiX® 86 has failed to properly calibrate. Failed calibrations run in TüN® Software will also list the cause for a calibration's failure. Please read below for causes and possible troubleshooting solutions.
| Calibration Error Code | Possible Cause | Possible Solution |
|---|---|---|
| 1 Short Red Flash: Calibrated response not flat | OEM soure unit tone/EQ controls not set flat | Verify OEM soure unit tone controls are set to ZERO/FLAT or "Centered" and turn off any source unit EQ or DSP Modes |
| Reversed polarity at one or more inputs | Double-check wiring of "OEM Analog Inputs" | |
| 2 Short Red Flashes: Incomplete audio spectrum | Disconnected or incorrect input connections in multi-way system | Connect input plugs, 1-pair at a time and check for green "Input Status" LED's when playing Calibration Track |
| Use RTA to view output spectrum to identify response gap for correction. Attempt to "Fill the gap" by substituting a different L/R channel pair and recalibrate | ||
| 3 Short Red Flashes: Delay Compensation Failure | Poor connection integrity | Double-check "OEM Analog Input" plugs for open or loose connections |
| Elevated OEM system noise floor | Disconnect any redundant input plugs already carrying audio content available via other input plugs and recalibrate | |
| Recalibrate at a lower (or higher) OEM source unit volume setting | ||
| 4 Short Red Flashes: No/Low Input Signal Level | OEM source unit volume set too low | Increase OEM source unit volume and recalibrate |
| FiX®: Valet Mode is engaged | Ensure Valet mode is not active (Signal Status LED's off, LED on DRC-100 knob slowly flashes green) | |
| Too low or missing signal from OEM inputs | Make sure Input Status LED's are green during audio playback. With multiple inputs, insert input connectors one at a time (input channels 1/2, 3/4, 5/6, 7/8) while playing the Calibration Track and confirm both L & R Signal Status LED's are green during playback | |
| Verify the OEM outputs are "on". The OEM source unit may need to "see" a speaker load to turn on. | May need to install a FiX-LSA-4 (sold seperately) to activate OEM amplifier outputs |
