Rockford Fosgate 5.3x manual High Level Inputs

◆High Level Inputs

The high level inputs on the Rockford Fosgate amplifiers convert the speaker line outputs (high level) to preamp line inputs (low level). This allows amplifier compatibility with a variety of source units as well as the ability to integrate into factory systems without the need for external adapters.

THE RESULT: Allows compatibility with factory and aftermarket source units.

◆XCard Crossover

The 5.3x amplifiers utilize internal active crossovers. These cross- overs have many performance advantages such as using discrete components for exact frequency adjustments which are far superior to potentiometers. Additionally, the XCard can be configured for high-pass, low-pass and full range operation. With slight modifica- tion, many crossover frequencies and slope configurations can be achieved.

THE RESULT: Increased system design flexibility with a precise electronic crossover without the limitations of conventional poten- tiometer designs.

◆Signal Switching Network

The Signal Switching Network allows the RCA input signals to be distributed to the amplifier channels in many different configura- tions. Among the many possible configurations, one setting uses a single RCA (L mono) to feed the subwoofer channel, thus simplifying connections needed.

THE RESULT: Allows input signals to be distributed to amplifier channels in many different configurations.
