Product Information

Amplifiers with a small footprint and big impact. GTR mono and full-range, multi-channel amplifiers deliver the efficiency and power you expect from Class D amps—and the performance you expect from JBL. Each model in the lineup will accept either high-level or low-level inputs, allowing the JBL Stadium amplifiers to be added to virtually any car audio system, including factory installed systems. The 2-, 4- and 5-channel amplifiers offer Bluetooth® audio streaming, exclusive Clari-Fi™ music restoration technology that analyzes and improves the audio quality of compressed files in real time, a multi-pairing Party Mode that lets anyone in the car stream music, and a cabin-mounted control panel. GTR amplifiers give you the power to shape your car audio experience in new ways.

GTR-1001 Features:

Bluetooth® audio streaming and telephony support

The two full-range, multi-channel GTR amplifiers 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-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-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 multi-channel amps come with a wired control panel that incorporates an omnidirectional 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 include full-range line outputs. This enables them to pass the audio signal to additional amps that power subwoofers, increasing your system configuration options.

High-Level Low Level Inputs

The GTR-1001 will accept both high level and low level inputs which allow for interface to both factory head units and aftermarket head units. A simple switch is provided to properly set the input level correctly. To ease installation from high-level inputs, proprietary bare wire to RCA connector adapters are included.

Variable Electronic Crossover

The GTR-1001 has a built-in variable electronic crossover which allows for precision tuning of your subwoofer. Tuning is available from 32Hz-320Hz. Their crossovers are low-noise and easily adjustable using a small slotted screwdriver versus finger controlled crossovers to ensure the setting stays put.

Variable Bass Boost Control

Looking for a little extra thump, the GTR-1001 comes equipped with a variable bass boost control which allows you to tune your box based on type and location.
