OPTIONAL ACCESSORY MODULES
Xtant optional accessory modules are easily and quickly
installed by your Authorized Xtant Dealer. The upgrade
modules snap into place on the amplifiers PC board when the top
of the unit is removed. These accessories enhance your entire system, expand-
ing and customizing performance for your unique application.
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 gain adjust-
ments. Any frequency from 20 Hz to 20kHz can be chosen.
The “Q” ranges from 1 to 10 in value, providing a wide range
of adjustment to address the subtle tuning requirements common with most
mobile audio systems.
24 DB / OCTAVE CROSSOVER MODULE – CM 24X
The CM-24X is a 24 dB per octave “Linkwitz - Riley”
crossover filter. The CM-24x module improves loudspeak-
er polar response while its steeper slope provides
enhanced system design flexibility.
12 DB / OCTAVE FILTER MODULES – CM 12H & CM12L
The CM12H and CM12L are 12 dB per Octave “Butterworth” filter networks
dedicated to either a High-Pass function (CM12H) or Low-Pass function
(CM12L). Each module is designed to be plugged into any accessory port on
Xtant’s 301a and 302a amplifiers. Frequency adjustment is via a 12 pin plug-
in resistor SIP (Single In-line Package) and 13 different frequency SIPS are
available from your authorized Xtant Dealer.
RESISTOR MODULES – RM4, RM8, RM12 & RM16
The RM 4, 8, 12 & 16 resistor modules are designed to activates
the “passive speaker terminals” on the 302a while providing
four different levels of attenuation for the speakers con-
nected to these terminals. The RM 4 module offers 4 dB of
attenuation, the RM 8 offers 8 dB of attenuation, the RM 12
offers 12 dB of attenuation and the RM 16 offers 16 dB of
attenuation.
