Direct Input Bussing

There are independent Direct Input Bus DIP switches for each channel on the A1240. These
DIP switches are located directly below the BUS L/R DIP switches and are labeled 1-12.
Their purpose is to allow the creation of summed mono signals without having to use addi-
tional patch cables. For example, if A1240 Input #1 is being fed a monaural signal, and Input
#2 needs to receive that same signal, slide the DIP switch labeled "1" to the left, (ON) position
for both channels 1 and 2. Direct Input Bussing is for channel pairs only (1/2, 3/4, 5/6, 7/8,
9/10, 11/12). In other words, Channel 3 can only be sent to Channel 4, and Channel 4 can only
be sent to Channel 3.

The example below shows the use of the Left (odd numbered) inputs. The Right (even-
numbered) inputs can also be used. Make sure to set the DIP switches correctly, as shown
below, depending on whether Right or Left inputs are being utilized.
