Tandem mode
In tandem mode two or four of the amplifiers inputs are linked together. To use only one input signal to
drive inputs A or B press the (A+B link/bridge) switch and connect a signal to inputs A or B.
In this configuration loudspeaker 1 would then be connected 1 and -1, and loudspeaker 2 across
+2 and -2 of the OUTPUT A, B Speakon connector.
To use only one input signal to drive inputs C and D press the (C+D link/bridge) switch and connect a
signal to inputs C or D, loudspeaker 3 would be connected 1 and –1 and loudspeaker 4 across
+2 and -2 of the OUTPUT C, D Speakon connector.
To use only one input signal to drive all four channels, press “IN” the A+B link/bridge switch, the C+D
link/bridge switch, and the link B+C switch.
All attenuators are active, allowing you to set different levels for each channel. Note that only the inputs
are connected in parallel. This is NOT a parallel output mode.
Never connect either output terminal to
ground or in parallel.
You can use the remaining input connectors to parallel off “Daisy-chain” signal to other amplifiers.
NOTE: Always turn off the Link switches when using the amplifier for dual Bi-amping.

Bridge mono mode
Bridge mode is used to deliver increased power to the loudspeakers.
Using the MA200Q in bridge mode reduces the number of output
channels from
four
to
two
. The nominal impedance of the load must be
more than 3 ohms. To bridge channels A and B set the A+B link /bridge
switch to “IN” and use either input connector A or B. Both the A and B
level attenuators must be in the same position, we recommend they are
used in the 0dB fully clockwise position. The loudspeaker load will now be
connected to +1 and -2 on the OUTPUT A, B connector. (+1 should be
connected to the [+] positive terminal of the loudspeaker and -2 to the [-]
negative terminal of the loudspeaker) Channels C and D are bridged in
the same way using the C+D link/bride switch, the output appearing on
the OUTPUT C, D connector (pins +1 and -2).
