Xtant RM-12 User manual

RM MODULES
Designed for use with the X Series Amplifiers
Increase Tuning Options and Staging
Speaker Level Attenuation: Via Resistors
Number of Resistors:  per module
Levels of Attenuation:
RM-4 = 4 dB
RM-12 = 12 dB
Inserting an RM module onto its associated port
activates the “passive speaker terminals” located
on the X Series amplifiers The RM  & RM 
resistor modules are designed to provide two
different levels of speaker attenuation

INSTALLING AN RM MODULE

INSTALLING AN RM MODULE
STEP 2: Selecting an RM Mo ule
INSTALLING AN RM MODULE
STEP 3: Plugging-in the RM MODULE
A Turnoff amplifier Remove amplifier cover and
locate the two RM Module receptacles
B Align the RM Module and press it onto the port
by applying downward pressure There is no
polarity that needs to be observed Be sure that
the connectors are fully seated
C Turn amp on and audition the system If further
ad ustment is necessary turn amp off
and exchange the RM Module for a higher or
lower value
WWaarrnniinngg::the RM Modules will become HOT during
normal use To avoid burns caution should be
taken when exchanging an RM Module
A Remove the RM Module from the packaging
and inspect the circuit board
B Locate the two connectors soldered on the
bottom of the circuit board See illustration 
C Simply align the two connectors with the two
circuit board mounted receptacles located on
the “X” Series amplifiers and plug the RM Module
into place by applying downward pressure
The RM Modules serve two purposes First they
activate the “passive speaker terminals” on the
Xtant amplifiers and secondly they add  or 
dB of attenuation to the speakers attached to
the “passive speaker terminals” Normally the
rear fill speakers are attached to the
“passive speaker terminals” but any speakers
(ie tweeters / center channel) that you desire
to attenuate (turn down) may be attached to
these terminals The appropriate module is
dependent upon speaker efficiency and the
distance of the listener to the speakers In a
mini or standard pickup truck where the rear
speakers are in relatively close proximity the
higher value RM  may be appropriate In a
sedan or coupe the RM  may be better suited
The modules are easily interchanged and a little
experimentation will help you determine the
best value
