Modes of Operation, Effects Loop, Output Feeds

Operation

Effects Loop

The effects loop connectors act as an insertion point for outboard signal processing equipment when the M-Class is operating in either the 70V Mono or Dual Mono modes. In these modes, the inputs and front panel controls form a 2:1 mixer. Connect

the Effects Loop Out to the input of the external signal processing equipment. Connect the Effects Loop In to the output of the external signal processing equipment. Inserting

an RCA jack into the Effects Loop In connector will automatically disconnect the input module signals from the power amp stage so it can be routed through the external equipment. Removing the jack from the Effects Loop In connector will reestablish the direct connection of the input modules to the power amp stage. The Effects Loop signals are quasi-balanced, which means that they are intended for use with unbalanced equipment but will improve the noise immunity. However, it is still a good practice to keep these connections as short as pos- sible.

Output Feeds

Two different output feeds are provided that can supply signal to other amplifiers and audio equipment. Both outputs are designed to feed high-impedance, unbalanced inputs

of external equipment.The outputs are also quasi-balanced for better noise immunity, but connection lengths for these outputs should still be kept as short as possible.The Pre-EQ Output Feed provides the signal before any external signal processing effects it.

The Post-EQ Output Feed provides a signal that has been affected by the external signal processing equipment and lo-cut filter. Depending on the application, it may be more desirable to use the externally-processed signal rather than the raw version of the signal.

Modes of Operation

Stereo Mode

Placing the 3-position switch to its left most position puts the amplifier in the stereo mode of operation.The amplifier supplies two independent channels of low-impedance amplification in

this mode (see Stereo Mode Block Diagram).These channels can

be used to supply left and right audio for stereo installations of 2 separate zones of amplification with different audio programs.

When using the supplied BAL1S input module in this mode, the

input applied to the "A" input will be controlled by the "A" level control and the output will be available on the "A" channel speaker terminals. Likewise for the "B" channel.When using other modules, there are jumper set- tings that allow those modules to apply signal to the "A" or "B" channels, or both. See the application examples for more information on how to use the two audio buses.
