GTR AMPLIFIERS CHAPTER 2: INSTALLATION AND WIRING What’s in the box: 1 amplifier 2 spare fuses (X3 GTR-7535, GTR-1001; X1 GTR-102) 1 cabin-mounted control panel (GTR-102, GTR-104 and GTR-7535 models) 4 RCA adapters (X2 GTR-102, GTR-601, GTR-1001) 1 REM adapter (GTR-102 and GTR-104 models) 4 screws Owner’s Manual Precautions: IMPORTANT: Disconnect the vehicle’s negative (–) battery terminal before beginning the installation. • Wear protective eyewear when using tools.
GTR AMPLIFIERS 1. Speaker output connectors: Connect speakers to terminals observing proper polarity: connect each speaker’s positive (+) lead to the appropriate positive (+) terminal, and negative (-) lead to the appropriate negative (-) terminal. • The GTR-102 features L+, L-, R+, and R- terminals ◆ For 2-channel operation connect the left speaker to the L+ and L- terminals, and right speaker to the Front R+ and R- terminals.
GTR AMPLIFIERS For 3-channel operation connect the stereo speakers to the Front terminals as described above. Connect the single speaker’s + lead to the Rear L+ terminal, and the - lead to the Rear R- terminal. For 2-channel (bridged) operation connect one speaker’s + lead to the Front L+ terminal, and the - lead to the Front R- terminal. Connect the other speaker’s + lead to the Rear L+ terminal, and the - lead to the Rear R- terminal.
GTR AMPLIFIERS 4. Remote (GTR-601, GTR-1001, GTR-7535): Connect an 18awg wire from the “Remote Out” lead of the source unit to the REM input. This lead detects signal and instructs the amplifier to turn on. (See 12. REM below for remote connection info for the GTR-102 and GTR-104 models.) GTR REM input power block +12V REM GND 5. Front and rear inputs and outputs (RCA): • If your source unit offers preamp outputs, connect to the FRONT, REAR, and/or SUB inputs using RCA patch cables.
GTR AMPLIFIERS 12. REM (GTR-102, GTR-104): Connect an 18awg wire from the Remote Out lead of the source unit to the included connector, and then plug the connector into this input (see illustration below). The REM lead detects signal and instructs the amplifier to turn on/off. GTR remote lead connector Remote turn-on lead from source unit In addition to REM inputs that turn on the amp, there are REM outputs that can be used to turn on other amps.

GTR AMPLIFIERS 28. Clari-Fi button: Press this button to engage Clari-Fi, which automatically applies the appropriate amount of Sound Restoration technology required by the signal coming into the amp, whether through high-level inputs, low-level inputs, or wirelessly. Leave Clari-Fi engaged since it automatically detects and restores compressed music files and will have no effect on uncompressed sources.
GTR AMPLIFIERS Setting the input level controls To match your amplifier’s input sensitivity (gain) to your source unit’s output level, we recommend the following procedure: A. Turn both input level controls counterclockwise to MIN (minimum). B. Play a dynamic music track through your source unit. Turn the source unit’s volume control to the 3/4 position. C.
GTR AMPLIFIERS CHAPTER 5: TROUBLESHOOTING PROBLEM: No audio and POWER INDICATOR is off. CAUSE and SOLUTION: No voltage at BATT+ and/or REM terminals, or bad or no ground connection. Check voltages at amplifier terminals with VOM. PROBLEM: No audio and PROTECT INDICATOR flashes every 4 seconds. CAUSE and SOLUTION: DC voltage on amplifier output. Amplifier may need service. PROBLEM: No audio and PROTECT INDICATOR is on. CAUSE and SOLUTION: Amplifier is overheated.
