INTRODUCTION
The Gates 994 6158 002 Stereo Control Console is a versatile and
efficient ten channel audio control center especi.ally designed to
fill the need for such equipment created by the establishment of
FM stereo broadcasting.
This console provides for the nixing cueing, and moni toring of a
variety of program sources.
These sources include microphones,
turntables, tape recorders, remote pickups, and networks.
These
signals are fed to the two stereo channels in the transmitting
system.
Due to the flexibility of the console, other combinations of out·-
put feeds are also possible.
.Provisions are inCluded for the ad·-·
dition of a third. output channel so that, simultaneously with the
Fl'I
stereo program feed, a compatible signal (combination of left
and right) may be fed to the
A.."1
transmitter.
This third channel
may also be used to broadcast a completely different monophonic
signal to the
Al"I
transmitter.
\men stereo programs are not being
broadcast, the two output channels of the console may be used t;o
feed a monophonic signal to two transmitters simultaneously, or
two completely different programs may be handled at once.
Microphone input sl-,i tching is arranged so that a single microphone
can feed both channels for isolated monophonic announcements on
stereo broadcasting.
Or, two microphones can be used for stereo
announcements.
Stereo monil;oIing of ooth bhe program output and
the audition bus is provided, as w·e.lI as an external stereo monj.·-,
tor ampli.fier input.
More details on the operation of the console may be found in the
section of this book titled OP'G'RATION.
The console is completely transistorized and self,-contained except
for the power transformer, which h8.s been placed externally to
minimize hum pickup in the console and the earphone jack panel.
Breaki.ng and jumpering of all major circuits allows full use of
normal ling jack fields, with all comlections brought out to ter'--
minal blocks for ease of installation and fu'ture circ'.lcit
check-.
ing.
Three speaker muting and warning light relays are supplied
with provisions included for the add.ition of a fourth relay.
Compensation of si.gnal levels by the use of fixed pads throughout
the console minimizes the necessity of readjusting gain controls
\'I"hen switching from one c ircui t to another.
The cue,-intercom system provides cueing of turntable and tape
sources as well as intercom faci.lities between the control room
and each of the studios as v,el1 as the remote lines.
The cue-
intercom system is interlocked with the speaker muting relays
so that cueing and intercom signals cannot inadvertently get on
the air.
