Stereo Inputs
Channels 7 and 8 provide two inputs for each channel. These are intended for stereo use‚ as each
input (Left‚ Right) has a fixed assignment to the Left and Right output buses. Additionally‚ a sum of
both inputs is fed simultaneously to the Aux output bus. Although you cannot change the distribution
of these inputs‚ you can determine if they are stereo or mono. The Mode switch‚ when enabled‚ will
sum both connectors‚ feeding both to the Left and Right outputs simultaneously. These connectors
accept nominal levels of -10 dBV.

The cabling for these connectors should be of the standard‚ consumer unbalanced shielded type. If you are using a 2-
conductor shielded cable‚ make sure to connect the negative side of the signal to the shield. Note: Unbalanced signal
sources should be located within approximately 6' of the SMR™821a.
The Mode switch selects either Stereo mode or Mono mode
individually for channel 7 or 8. In Stereo mode‚ the Left input
signal feeds the Left mix bus and the Right input signal feeds the
Right mix bus via the front panel Level control. In Mono mode‚
the summed Left and Right signals feed both the Left and Right
mix buses. This allows for only one input to be used to feed
stereo mix buses. Additionally‚ it allows for Left and Right
outputs of the source to be summed without a Y-cable. In
either mode‚ a summed mono signal feeds the Aux mix bus.
