Gravity GR-BASS2.0 Digital Bass Processor

The Gravity GR-BASS2.0 is a digital bass processor designed to restore and enhance low-frequency information in a vehicle audio signal. It is intended for factory or aftermarket systems that need more defined bass response without changing the source unit. By working in the signal path, it gives an installer a dedicated way to shape bass before the signal reaches downstream equipment.

This processor is suited to listeners who want stronger low-end presence while retaining control over the character of the bass. Its bass restoration and bass maximization functions are designed to add back low-frequency content that may be reduced in the original recording or playback chain. The result is a system tuning tool focused on fuller, more controlled bass reproduction.

The GR-BASS2.0 incorporates a bass equalization circuit and a PFM subsonic filter. The filter helps reduce extremely low-frequency content that can use unnecessary subwoofer excursion and amplifier power. This makes the processor a practical option for systems using subwoofers where bass level and low-frequency management need separate adjustment.

With a maximum input level of 15V RMS and a maximum output level of 13.5V peak, the processor is specified for use in higher-voltage car-audio signal paths. Its stated 10 Hz to 100 kHz frequency response, 0.003% THD rating, and greater-than-60 dB balanced input noise rejection support clean signal handling. Gold-plated contacts are used to support dependable signal transfer at the connections.

A dash-mount remote control is included for convenient bass adjustment from the front of the vehicle. The main unit also features illuminated controls, an illuminated logo, and a bass maximizer indicator for easier visibility in low-light installations. Its compact 9-inch-wide chassis can be integrated as part of a bass-focused upgrade alongside compatible source, amplifier, and subwoofer components.

Design & Installation

The GR-BASS2.0 uses a compact chassis measuring 9 inches wide, 6-1/2 inches deep, and 2-3/4 inches high. Its design includes gold-plated contacts, illuminated control knobs, an illuminated logo, and a bass maximizer indicator. A high-headroom PWM power supply is specified for the processor.

Install the processor in the system signal path and leave access to its controls for initial tuning. The included dash-mount remote is intended to be positioned where bass adjustment can be made conveniently while seated in the vehicle. Use a properly fused installation, following the product instructions and the requirements of the connected audio system.
