(see Figures 10 & 11)
5.4.1 Stereo/mono switch
Located on the motherboard of the input module, this switch selects between NORMAL
STEREO, DUAL MONO, or BRIDGED MONO operation.
For NORMAL STEREO operation, use CH 1 and CH 2 inputs. For DUAL MONO or BRIDGED
MONO operation, use CH 2 input only. See the section on bridged operation for more information.
5.4.2 Clipping eliminator switch
You can bypass the clipping eliminator circuit with this switch (located just to the right of
the input panel). Turning the switch OFF deactivates the clipping eliminator and allows the
amplifier to clip when driven beyond its maximum output capability. The clipping eliminator
is operational at the point of manufacture (switch in the up position). For more information
on how the clipping eliminator circuitry works, see Section 4.9.
5.4.3 Input connectors
There are two input connectors per channel which enable three different types of input
connectors to be used. A combination 1/4" TRS (Tip-Ring-Sleeve)/XLR input connector on
the input module allows for either a 1/4" TRS input or a XLR input. A quick connect terminal
block input is also on the input module and is wired in parallel with the TRS/XLR input
connector. This allows for easy connection of stripped wires to a connector which is
provided. Two parallel input connectors allow for simple connection of parallel amplifiers.
Note
When in mono mode, use CH 2 input only.
