Inputs and Outputs
Top-Mounted Controls: The
XA2125 amplifier features convenient, top-mounted controls for quick access.
Internal Crossovers: The
internal crossover is a 12dB/octave filter selectable for high-pass, full-
range, or low-pass operation. Each channel has a separate control that allows
you to independently adjust the crossover frequency from 40Hz to 400Hz.
The amplifier includes a control that allows you to boost bass from 0 to
+12dB, centered at 45Hz.
Control: The remote gain control knob can be
mounted in the front of the vehicle and is wired to the amp via the included
cable (with phone type jacks at both ends). The remote control is 1.008"
tall, 2.542" wide, and 1.748" deep (2.092" including the knob).
RCA Preamp Outputs: The
gold-plated preamp output jacks provide a convenient source for daisy-chaining
an additional amplifier without running an extra set of RCA cables from the
front of the vehicle to the amplifier location. These RCA jacks output a
Protection Circuitry: Thermal,
short circuit, low impedance, and DC offset circuits are used to help protect
the amplifier from damage and ensure reliable operation.
