Thank you fortpurchasing AZDEN’S “PERFORMANCE SERIES“ wireless system. This manual oovells th
3 l lDRH, 3 l IDR, 221R, 21 IR and ZOOR receivers and the SZBT (Lavaliere), 31XT (Plug-in XLR), SlHT
(Handheld), 3lLT (Lavaliere) and 3llT (Instrument) transmitters.
Receiver Descriptions
The SllDRH True Diversity VHF Half-Rack Receiver:
The 311DRH contains two separate receivers, each operating on the same frequency. The incomip signal is
constantly monitored by a diversity circuit, which switches automatically to the receivenwiththgx' nger RF
signal. This allows wireless performance that is virtually dropout free, even under the m h ‘ condi-
tions. The receiver features l/4-inch as well as XLR output jacks with volume and squelc
(1) Power LED and Orr/Off switch.
Afier plugging in the 3 I l DRH depress the On/Olf switch to turn unit on and illuminate the Power LED. See
#5 for more details, l '
(2) Antenna A-B LEDs.
When the transmitter is turned on and is in reception range of the receiver, either the A or B LED will light up
GREEN, depending on which receiver circuit is getting the strongest signal from the transmitter. Flickering
from the A to B LED is a normal function of the system. i
(3) Radio Frequency level and Audio level LEDS.
The 3] IDRH has two 5-segrnent LED displays to show the strength of both the incoming FM carrier and the
audio signal level, The receiver will perform best if the RF level is kept between the fourth and fifih LED.
Dips to the third LED may happen occasionally and are tolerable. The audio level LEDs will show the incom-
ing audio signal from »26dB to +5dBi The'fifih LED is red and will come on ifthe audio component of the
incoming signal is approaching distortion,
(1)
(4) Antenna connections.
On the 31 IDRH the, antennas are connector mounted.(BNC) so that the supplied antennas can be disconnected
and/or remoted using coax cable if needed.
(5) 12-Volt Input
Plug the supplied’AC adaptor into the l2-volt input on the receiver and then into a 110-120 VAC electrical
outlet. Use only the adaptor supplied (BC-26U) as other adaptors may damage the receiver.
(6) Output Adjustment.
Rotate this knob clockwise to increase, or counter-clockwise to decrease volume level.
(7) Output (unbalahced)
Using a suitable audio’oable (not supplied), connect the l/4-inch phone jack end to the audio output on the
receiver and connect the other end of the cable to the suitable mic/line input of an audio mixer or amplifier.
(8) Output (balanced).
Using a suitable audio cable (not supplied) connect the XLR connector to the audio output on the receiver, and
connect the other end of the cable to the suitable mic/line input of an audio mixer or amplifier:
(9) Rack cars.
If you wish to use the 31 lDRH in a standard 19" rack by itself you can use the HR-l rack kit and attach the
rack ears using the four supplied machine screws (two per side near front) as shown. If you wish to use the
131le in a standard 19" rack with another 3] lDRI-l or a 41 lDRH you can use the HR-Z rack kit and attach
the rack ears using the four supplied machine screws (on the outer sides of each unit) as shown. Also attach
the joining plate (supplied) underneath the two units by screwing in the supplied machine screws We also
suggest that you remove the “feet” from the bottom of the receivers for the proper clearance required in a
standard rack. (see diagram.)
00) Squelch adjust.
Thisadjusts the point at which the receiver will shut off or “squelch” the incoming RF signal when it be-
comes too weak. Turning the control counter-clockwise raises the threshold, allowing more signal to enter
while turning the control clockwise lowers the threshold, letting in less signal.

OPERATING THE SYSTEM
Do not place the receiver on a metal surface, and avoid obstructionsrbetween the receiver and transmitter.
since this could degrade the performance of the equipment,
First, make sure that the power to all your components is turned off. Cannect an audio cable from the output of
(11)
the receiver to a mic/line input on your audio mixer or amplifier. Plug the receiver’s AC adaptor into the l2V
input jack on the receiver, and then plug it into the llO—IZO VAC electrical outlet. With the volume of your
mixer or amplifier set to minimum level, turn your system’s power on. Turn on the transmitter(s). Make sure
all LEDs on the receiver and transmitter(s) are operating as described in the preceding pages. Now set the
receiver‘s volume to the midway point and adjust the volume level on your mixer or amplifier.
32BT, 31LT & 31XT: With someone talking into the microphone, turn the volume on the mixer or amplifier
to the desired level. If there is too much, or not enough gain, lower or raise the volume on the receiver. If the
sound is distorted, lower the input gain on the transmitter.
3 lHT: With someone talking or singing into the microphone, turn the volume control on the mixer or ampli-
fier to the desired leveL lfthet'e 15 too much, or too little gain, adjust the volume on the receiver. If the sound
is distorted move memicrophone further away from the sound source
31th Plug the cableiinto a guitar or bass. Set the instmment volume to the midway point. While playing the
instrument adjust the volume an the mixer or amplifier to the desired level. If there' is too much, or too little
gain, adjust the volumeton thereaewer. If the sound IS distorted lover the input gain on the 31 IT With the
system now operating, move around the performing area to make sure no problems, such as feedback or RF
signal loss occur.
NOTES:
- Do not use or store the system in areas of high temperature or humidity.
- Do not use the system near a broadcast station, airpon, or airplanes, as it may cause interference. If you are
interfering with other transmissions, you must turn the system off.
- These systems contain no'user-serviceable parts. lf any unauthorized service is performed, it may void the
warranty.
FCC NOTES:
AZDEN 32BT, 31HT, LT, IT, and XT, conform to Parts 74 & 90 of the'FCC rules. The receivers conform to
part 15 of the FCC rules You should contact the FCC office near you‘for the proper filing forms.
