◆ 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.
