Power, Ground and Remote Trigger

1. Power Connector – The LC7i PRO requires constant +12V power and a

good ground to operate properly. Connections should be made with 16

to 14 gauge wire.

+12V - Connect this to a constant +12V source, like the positive battery

terminal. Fuse at 2 amps.

Ground - Connect to the negative terminal of the battery, a ground bus,

or a verified ground.

Rmt Out - Connect the LC7i PRO +12V remote output to your amplifier's

remote input.

Rmt In - When Trigger Mode, explained below, is set to Rmt In, connect

this to your +12V remote trigger. When using GTO or Audio trigger, no Rmt

In connection is necessary.

2. Trigger Mode – The Trigger Mode switch controls how the LC7i PRO turns

on and off. The default and favorite position is GTO.

Rmt In - This is the traditional way to turn on the LC7i PRO and gives you

more control of exactly when the unit will turn on. Most common places

to connect the remote input are from the ignition of the vehicle, fuse

box, or some other +12V source that turns on and off with the key.

GTO™ - DC offset and Class D switching frequencies are high-falutin

technical terms that mean the LC5i PRO can sense when the head unit or

amplifier is on, not necessarily when audio is being sent to the LC5i PRO.

Use GTO Signal Sense mode when your factory sound system outputs a

DC offset or has a Class D amplifier.

Audio - When this mode is selected, the LC7i PRO will ONLY turn on

when you start playing an audio source from the head unit. If you turn

the head unit on, but DON'T play audio, the LC7i PRO will not turn on

3. Ground Isolation – This handy switch allows the you to change how the

LC7i PRO is grounded. Sometimes when installing car audio equipment,

"ground buzz" or "alternator whine" will creep into the audio path, wreak-

ing havoc on your listening experience. There are 3 positions; GND, ISO,

and 200 ohms. The unit ships from the factory in the ISO position.

GND - Power ground and audio ground are tied together.

ISO - Power ground and audio ground are separate.

200Ω - There is 200 ohms of resistance between power ground and

audio ground
