" phone

jack. Can be connected to an unbalanced aux-level
input of a mixer, guitar amp or tape recorder.

17  AC POWER: IEC-type connector for 120-240V AC

50/60 Hz power input. No adjustment for mains 
voltage/frequency is necessary.

18 POWER CABLE CLAMP: Use provided cable clamp

to secure the plug in the chassis connector.

19 GROUND TERMINAL: Case grounding screw, if 

needed.

Rear Panel Controls and Functions (Fig. D)

Antenna “A” / Antenna “B”

12  INPUT JACKS: BNC-type antenna connectors for “A” 

and “B” Tuners in both receivers. Attach antennas
directly, or extend them with low-loss antenna cable.
See the “Antennas” section on page 3 for more details.

13  OUTPUT JACKS: Provide RF distribution to other

receivers operating in the same frequency band. Each
output should be connected to only one other antenna
input, without “daisy-chaining.” (Using two additional
ESW-R220 dual receiver units provides a total of six
channels in three rack spaces with a single pair of
antennas.)

Receiver 1 / Receiver 2

14  GROUND LIFT SWITCH: Disconnects the ground pin 

of the balanced output (15) from ground. Normally, the
switch should be to the right (ground connected). If
hum caused by a ground loop occurs, slide switch to
the left.

15  BALANCED AUDIO OUTPUT JACK: XLRM-type connec-

tor. A standard 2-conductor shielded cable can be used
to connect the receiver output to a balanced micro-
phone-level input on a mixer or integrated amplifier.

Front Panel Controls and Functions (Fig. C)

1   POWER SWITCH: Press switch On and the Channel

Designator Displays (5) will light.

Receiver 1 / Receiver 2

Controls and operation of the two receivers are identical.

2  AF LEVEL INDICATOR: Indicates the audio modulation

level of the received signal. The LEDs light up from left 
to right.

3

RF LEVEL INDICATOR: Indicates the strength of the RF
signal received from the transmitter.

4

TUNER OPERATION INDICATOR: Indicates which Tuner
(A or B) has the better reception and is in operation.
Lights only when receiving an ES transmitter’s signal.

5

CHANNEL DESIGNATOR DISPLAY: Indicates the current 
channel setting.

6

CHANNEL SET BUTTON: Hold this button in and
press “Up” or “Down” to change the channel shown
in the Channel Designator Display.

7

CHANNEL SELECTOR “DOWN” SWITCH: Changes
the channel designator, decreasing from 99 to 00.
“Rolls over” from 00 to 99.

8

CHANNEL SELECTOR “UP” SWITCH: Changes the
channel designator, increasing from 00 to 99. “Rolls
over” from 99 to 00.

9

“PHONES” LEVEL CONTROL: Adjusts the level of 
the headphone jack only; it does not affect receiver
audio output.

10 HEADPHONE OUTPUT:

4

" TRS phone jack. Plug in 

a “stereo” headphone to monitor receiver signal.

11  MOUNTING ADAPTERS: For mounting the receiver in 

any standard 19" rack. Attach to receiver with screws 
supplied.
