Supplied CM12LFilter Module
Product Description: The CM12Lis a 12 dB per octave low pass filter network. This supplied mod-
ule is designed to be plugged into any accessory port tower on the 301a amplifier. Frequency adjust-
ment is via a 12 pin, plug-in resistor SIP (Single In-line Package). A 90 Hz SIP is factory installed and
an additional 13 crossover frequency SIPs are available from your Authorized Xtant Dealer.
Adding Accessory Modules: The 301a is equipped with three accessory docking ports. Two ports
are dedicated to the amplifier and are labeled Amp Vert/Horiz Acc. Port and Amp Vert. Acc. Port.
The third is dedicated to the RCA output signal and is labeled Line Out Vert. Acc. Port. Xtant offers
two types of accessory modules which are designed for either “Horizontal” or “Vertical” mount-
ing. The docking port labeled Amp Vert/Horiz Acc. Port will accept any of the modules, while the
ports labeled Vert will only accept modules designed for vertical mounting. The following is a list
