Channels 7 and 8 provide two individual 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 con-

nectors accept nominal levels of -10dBV.

The Mode switch selects either Stereo mode or Mono mode individ-

ually for Channel 7 or 8. In the 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 the Mono mode, the

summed Left and Right input signals feed both Left and Right mix

buses. This allows for only one input to be used to feed the 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.

The cabling for these connectors should be of

the standard, consumer un-balanced 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 approx-

imately 6’ of the SMR-821.
