®

 audio streaming and telephony support

The three full-range, multi-channel GTR amplifiers (102, 104 and 7535 models) feature Bluetooth

®

 

connectivity for wireless audio streaming from phones and other devices. You can receive phone calls 
through your car audio system, just by touching a button on an included control panel.

Clari-Fi

™

 audio restoration technology

Clari-Fi

™

, a proprietary DSP technology, is incorporated in the GTR-102, GTR-104 and GTR-7535 

amplifiers, analyzes music files and improves highly compressed digital music files in real time. A predictive 
algorithm restores audio content that is discarded in the compression process. Clari-Fi

™

 works with all 

playback devices and audio sources. It extends high-frequency bandwidth, restores the natural warmth of 
vocals and widens the sound stage. In short, Clari-Fi

™

 gives your digital music back its soul.

Party Mode wireless pairing
The GTR-102, GTR-104 and GTR-7535 amplifiers offer Party Mode, a multi-pairing capability that enables 
Bluetooth

®

 devices to stream audio individually. When Party Mode is selected from the cabin-mounted 

control panel, anyone in the car can drive the music.

Cabin-mounted control panel

The GTR-102, GTR-104 and GTR-7535 multi-channel amps come with a wired control panel that 
incorporates an omni-directional microphone and puts a range of functions at your fingertips. You can 
activate Bluetooth

®

 pairings, accept and end phone calls, select Party Mode and cancel Clari-Fi

™

. 

Class D amplification

Every GTR amplifier, including the full-range models, is a Class D. These high-efficiency, low-heat amps 
generate a lot of power without drawing much current, and feature small footprints. 

Full-range line outputs

The full-range GTR amplifiers (GTR-102, GTR-104 and GTR-7535) include full-range line outputs. 
This enables them to pass the audio signal to additional amps that power subwoofers, increasing your 
system configuration options.

Upgradable firmware 

GTR amplifiers incorporate a mini-USB port that enables you to easily upgrade firmware.

ADAS Input

The full range GTR amps feature an ADAS input which overrides the audio signal when connected to ADAS 
accessories.  In addition, ADAS alert routing location can be assigned during amplifier setup using the 
panel mounted control.
