MX SERIES MULTI ZONE AMPLIFIER OWNER’S MANUAL
Typical Mode
MX Series amplifiers can be configured as the main amplifier for an audio distribution system or home theater system.
When used with an audio distribution preamp or matrix processor, each zone can independently drive one of several
different sources by using each zone’s individual line audio inputs. If the specify zone needs a higher power, please just
use Bridged mode.
When MX 1280 or MX 1680 is working as a home theater amplifier, the amplifier could support up to a 7.1 or 5.1surround
system, and recommend using the Bridged mode to have the higher outputs.
Bridged Mode
When the amplifier is in Bridged Mode operation, a single channel (the left) is used to provide a higher power mono
output.Use one channel pair to amplify the left channel by connecting the left audio signal to the L input of a channel
pair, setting the Stereo/Bridge switch to “Bridge” and connecting the speaker as indicated below. Use a second channel
pair for the right channel by connecting the right audio signal to the L input of a second channel pair, setting the Stereo/
Bridge switch to ”Bridge” and connecting the speaker as indicated above. Note: The three position switch needs to be
set to “Line In” on both zones that are wired for Bridged Mode.
Wiring Instructions - Bridged Mode
• Turn off the amplifier and connect an 8-ohm minimum load.
• Set the Stereo/Bridge switch to Bridged Mode.
• Follow the Bridge mode markings on the back of the amplifier:
Connect the negative lead (-) of the speaker cable to the R– terminal.
Connect the positive lead (+) of the speaker cable to the L+ terminal.
• Apply the Line In from audio source to the Left Line In connector.
• Power on the amplifier.
