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

DIVERSITY

The R200 Series receivers utilize patented Se-

cure-Phase

diversity circuitry that provides the

strongest, cleanest signal possible. Unlike other

diversity circuits that switch antennas, Secure-

Phase

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.

R200 SERIES COMPONENTS
R200 Secure-Phase

Diversity UHF Receivers

Secure-Phase

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
