SYSTEM DESCRIPTION
The Shure SC Series wireless microphone system is a frequency-
selectable, diversity system operating in the VHF band between 169 and
216 MHz. Each SC Series system is capable of operating on eight different
frequencies (four different frequencies for SC systems operating in the
traveling band). Digital frequency control enables the system to produce a
clean signal, which allows up to 12 SC Series wireless systems to be
operated simultaneously in a single installation.

SYSTEM FEATURES
Frequency Agility
An eight position switch in both the transmitter and receiver allows the
system operating frequency to be changed should interference occur,
preventing the need to exchange units or re-crystal existing systems in
order to change frequencies.
Tone Key Squelch
A separate, inaudible signal is sent along with the transmitter carrier
frequency. When this tone is not present (e.g., the transmitter is either
turned off or out of range) and the tone key squelch switch on the receiver
is enabled, the receiver remains muted, and unwanted noise is prevented
from entering the system. In addition, by eliminating the popping sound
often heard when a wireless system is turned on or off, tone key squelch
allows the ON/OFF power switch on an SC transmitter to also function as
a system "mute" switch.
Transmitter Battery Fuel Gauge
When activated, a multicolor, five LED array illuminates to show how
much life remains in the transmitter battery. This allows the user to know,
rather than guess, when to change the battery.
Diversity Receiver (half-rack size), with rack mounting
