Frequently Asked Questions - LC7i PRO AudioControl
What is the AudioControl LC7i PRO used for?
The LC7i PRO is a line output converter that allows you to connect a factory stereo to aftermarket amplifiers by converting speaker-level signals to high-quality RCA preamp outputs with signal summing capabilities.
How do I power the LC7i PRO?
Connect the blue wire to a switched 12V source and the black wire to chassis ground. The unit can also turn on via GTO signal sense when audio is detected.
Can I sum signals from front and rear speakers?
Yes, the LC7i PRO can sum up to six channels into two RCA outputs using internal jumpers. This is useful for retaining fader control.
What is the GTO feature?
GTO (Great Turn On) automatically turns the converter on and off based on audio signal presence, eliminating the need for a remote turn-on wire.
How do I adjust the output level?
Use the input gain controls on the side of the unit. For remote level control, connect an optional AudioControl ACR-1 (sold separately).
What is the maximum input voltage?
The speaker-level inputs can handle up to 30V RMS (approximately 75W typical), making it compatible with most factory systems.
Will the LC7i PRO work with a factory amplified system?
Yes, it can accept high-voltage inputs from factory amps. Ensure the input gain is set correctly to avoid clipping.
How do I troubleshoot no sound output?
Check power connections (12V and ground), verify signal input connections, ensure GTO is not disabled, and inspect the gain setting. Also test with a known good source.
Can I use the LC7i PRO with an aftermarket radio?
While designed for factory integration, it can also be used with aftermarket radios if speaker-level outputs are used. However, most aftermarket radios have preamp outputs already.
What is the warranty period?
AudioControl provides a 5-year limited warranty from the original purchase date. Retain your receipt for warranty claims.
