Xtant optional accessory modules are easily and quickly

ules snap into place on the amplifiers PC board when the top of the unit is

tomizing performance for your unique applications.
PARAMETRIC EQUALIZATION MODULE – PQM 1
The PQM-1 is a precision tuning instrument, designed to be
adjusted with the use of a Real-Time-Analyzer. This true,
fully adjustable, one band parametric equalizer provides
individual frequency, Q/bandwidth, and +/- 18dB gain adjust-
ment controls. By utilizing one of three (3) frequency modules included, any
frequency from 20 Hz to 20kHz can be chosen. The “Q” ranges from 1 to 10
in value, allowing a wide variety of bandwidth adjustment to address the
subtle tuning requirements common to mobile audio systems. All 2-channel
Xtant amplifiers can accept one PQM-1. All 3/4-channel amplifiers will
accept two PQM-1 modules if desired (one PQM-1 per 2 channels of input).
BASS BOOST MODULE-LFQ45
The LFQ 45 is designed to add, 4, 8, or 12 dB of Bass Boost to any
sound system powered by an Xtant amplifier(s).
The LFQ 45 will enhance the bass performance of any sub-
woofer system, sealed or ported. However, if you are using the LFQ 45 with
a ported enclosure, be sure that the 45 Hz center frequency is at or above the
vent tuning frequency or damage may occur to the speaker.
