OVERVIEW

Each R-5 audio console is supplied with ten stereo line inputs; each
input can accept two stereo line signals which are accessed by an A/B input
selector switch at the top of the channel. Note there are two possible gain
settings provided for each A and B input: +4dBu (professional level
balanced inputs—the factory default) or an alternate –10dBu setting for low
level "consumer-type" equipment (the –10dBu setting is activated by wiring
jumpers in each channel's upper LOGIC connector; see top of page 3-5).
Each channel has its own CUE switch, allowing material to be previewed
prior to airplay; the CUE function is automatically deactivated when the
channel ON switch is pressed. At this point the channel signal is routed (at
the level set by the linear fader) to whichever console output busses have
been selected via the three ASSIGN switches (PGM, AUD and/or TEL)
Stereo line inputs also have built-in control circuitry that enables the
console operator to START and STOP external source machines by pressing
channel ON and OFF switches. Additionally, the channel's OFF switch
indicator LED can be controlled by a remote source machine, allowing it to
function as a flashing READY lite to show the operator when a machine is
cued up and ready to begin play. Finally, stereo line input channels may be
automatically turned off by the remote source machine (typically when it
has reached end-of-play). Detailed wiring information for these control
functions may be found on pages 3-5 and 3-6.
