5.4.3Tandem 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 across +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 across +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.

5.4.4Bridge 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).
