DESCRIPTION
The Electro-Voice R100 is a series of VHF wire-
less systems that combine EVs legendary quality
and reliability with high value. The R100 Series
transmitters and receivers operate in the VHF fre-
quency range between 174.100 and 185.350 MHz
(channels 7 8 in the TV band) on single frequen-
cies. The well-designed audio circuitry ensures
high signal-to-noise ratio with accurate sound
quality.
SECURE-PHASE
tm
DIVERSITY
The R100 Series receivers utilize patented Se-
cure-Phase
tm
diversity circuitry that provides the
strongest, cleanest signal possible. Unlike other
diversity circuits that switch antennas, Secure-
Phase
tm
utilizes the signal from both antennas at
all times to increase signal strength, minimize
dropouts and lower the potential for interference.
If the signal from the transmitter changes phase
or polarity (a common cause of dropouts), the cir-
cuit adjusts the phase angle between the two an-
tennas receiving circuits to prevent cancellation.

External AC power adapter minimizes noise
and makes voltage changes easy if necessary.
Power can also be supplied from a 12-volt bat-
tery or filtered power supply.
Permanently attached, specially-tuned anten-
nas are easy to position
RCV: VHF microphone receiver has smooth,
accurate response
GRV: VHF guitar receiver is specially designed
to handle the transients of a guitar
The R100 Series receivers are easy to set up and
operate. The only controls are the adjustable out-
put level and squelch controls. The antennas are
permanently attached telescoping types that are
easy to position and are tuned to the range of op-
eration. An optional rack-mount kit allows two sys-
tems to be mounted in a single rack space.
