1. Rackmounting the Receiver
TherearetwooptionsavailableforrackmountingtheEnc-DUETreceiver:
singly or side‑by‑side with another Enc Series receiver.
a. Single mounting: Remove the receiver SIDE MOUNT CLIP (1) from each side of
thereceiver(asshown)andslideintheoptionalERM-12 RACK EARS (9).
b. Side-by-side double mounting: After removing the SIDE MOUNT CLIPS (1) from
bothEnc receivers, join the two receivers with the EJC-2 JOINING CLIP (10)
and attach the ERM-22 RACK EARS (12) as shown.
(Note: Do not mount the receiver in a rack directly above an amplifier or
other source of high heat — this could degrade the performance of the
Enc-DUET. Always ensure adequate airflow and heat dissipation in
any rack configuration.)
2. Powering the Receiver
Plug the 12V AC/DC ADAPTER (15) provided into the DC INPUT JACK (11) on the
back of the receiver. Then plug the power supply into an AC outlet.
(Note: Any 12V DC source with 400mA capability can also be used.)
Press the POWER SWITCH (8) once to turn on the receiver. The POWER ON LED (7)
will now light and the receiver is operational.
3. Antennas
The Enc-DUET receiver is supplied with TELESCOPIC ANTENNAS (16), one each for
ChannelAandChannelB.Theseshouldbeextendedfullytoobtainmaximum
range.Optimalantennapositionis45degreesfromthereceiver(at90degrees
fromeachother).Formaximumrange,itisalwaysbesttomaintainalineofsight
(noobstructions)betweenthereceiverantennasandthetransmitteratalltimes
whenever possible.
4. Mute (Squelch) Adjustment
In normal operation, the MUTE CONTROLS (2) foreachchannel(A&B)shouldbeset
fully counterclockwise to the factory preset minimum RF level. However, in areas of
highRFactivity,themutes(orsquelches,astheyaresometimescalled)mayneedto
beadjustedtocompensatefortheadverseconditionsinaparticularlocation.If,with
the transmitter off, one or more LEDs of the receiver's 5 LED RF LEVEL DISPLAYS (4) for
thatchanneltransmitterickerorstayon,thesquelchcontrolforthatchannelshould
beturnedclockwiseuntiltheLEDsextinguish.Whenthesquelchisproperlyadjusted,
the RF LEVEL LED displays will only light when that channel transmitter is turned
on. Turning the squelch control too far clockwise will reduce the range, but yield a
quietermute(squelch)function.Whenthe5 LED RF LEVELdisplayextinguishes,the
transmitter for that channel is out of range for that given location, and the user should
move closer to the receiver to re‑establish the radio link.
