DESCRIPTION
The Electro-Voice R200 is a series of UHF wire-
less systems that combine EVs legendary quality,
reliability and high value. The R200 Series trans-
mitters and receivers operate in the UHF fre-
quency range between 710.100 and 721.350 MHz
(channels 54-55 in the TV band) on single fre-
quencies. The well-designed audio circuitry en-
sures excellent signal-to-noise ratio with accurate
sound quality.
SECURE-PHASE
tm
DIVERSITY
The R200 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.

diversity for maximum range
and reliability
Clean, undistorted sound reproduction using
proprietary compander circuitry
Audio output via rear-mounted XLR-type 3-pin
mic level or front-mounted, adjustable line level
¼-inch connector
May be rack mounted with optional kit
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
RCU: UHF receiver specially designed to re-
produce all the nuances of the voice
GRU: UHF guitar receiver specially designed to
handle the transients of a guitar
The R200 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.
HTU Handheld Transmitter
Electro-Voice BK-1 (HTUC) cardioid condenser
microphone transducer or Electro-Voice N/
D157 (HTUD) cardioid N/DYM dynamic trans-
ducer.
Separate LEDs for power on and battery status
for easy monitoring of operational modes.
Separate power and audio mute switches for
operational flexibility.
Wide-range gain control allows approximately
40 dB of adjustment.
Special soft-touch finish and ergonomically
designed handle makes holding comfortable
and secure.
Up to 10 hours of operation on a 9-volt alkaline
battery.
Bodypack Transmitters
Two models are available:
BPU: UHF bodypack with TA4F connector al-
lows the user the freedom of microphone se-
lection. Standard microphones include the
Electro-Voice ULM20 cardioid condenser
lavalier microphone and the HM2 headset mi-
crophone. The TA4F connector allows connec-
tion of any dynamic or condenser microphone
that can be biased with 5 volts dc phantom.
BGU: UHF guitar bodypack with hardwired
cable and ¼-inch connector with specially de-
signed audio circuitry to handle guitar tran-
sients
Separate on/off and large mute switches for
operational flexibility
LED battery condition indicator gives quick
indication of battery strength
