1. Introduction
Congratulation in owning one of these state-of-the-art PLL Synthesized 16 channels frequency
agile VHF high band (SDR-2716) professional wireless receivers. According to their frequency
range, these receivers are
designed to be matched with ITEC VHF high band PLL Synthesized transmitters (handheld or
beltpack).
The standard combinations are as follow:
SDR matches WT, or WM
As this is a shared operating manual of SDR-2716, we suggest you to read this
operating manual thoroughly in order to familiarize with each part of function before using.

2.1.1. Receiver Installation
For best operation, the receiver should be at least 1m
above the ground and at least 1m away from a wall or
metal surface to minimize reflection. The transmitter
should also be at least 1m away from a wall or metal
surface to minimize reflection. The transmitter should
also be at least 1m away from the receiver, as shown
in Fig.1.
Keep antennas away from noise source such as
motors, automobiles, neon light as well as large metal
objects.
Fig. 1
2.1.2. Audio output connection
There are two audio outputs on the back of the Diversity SDR receivers. Mic-level balanced and
Line-level unbalanced. Use shielded audio cable for the connection between the receiver and the
mixer. If the mixer / amp is a 1/4“ phone jack, connect a cable from the 1/4“ unbalanced audio
output from the receiver to the mixer / amp. If the mixer has an XLR input, connect a cable from
the balanced XLR audio output from the receiver to the mixer input. Audio output connection is as

2.1.3. Rack Mounting
SDR series are 1/2 19“ casing design and the specially designed 19“ rack mount adapter (MP-50)
is available as optional purchase for customers‘ installation request. The installation instructions
are shown as Fig. 3.
Fig. 3
2.1.4. RF Interference
If you encounter receiving interference (from other than an operating TV station), often it can be
overcome by adjusting the receiver‘s squelch control, as described on 5.2 (below).Please note that
wireless frequencies are shared with other radio services. According to FCC regulations, wireless
microphone operations are unprotected from interference of other licensed operations in the band.
If any interference is received by any Government or non-Government operation, the wireless
microphone must cease operation. The above statement is valid in the U.S.A.
2.1.5. Receiver Squelch control
The squelch control on the back panel of the receiver is preset at the factory, but can be adjusted
if you must use the system in a high RF interference area. If there is audio output from the receiver
when your transmitter is OFF, adjust the squelch control so the system will receive the signal from
your transmitter but squelch or eliminate the unwanted background RF noise. This adjustment
can cause a reduction in usable range of the
wireless transmitter, so set the control to the lowest position which reliably mutes the unwanted RF
signal.

These two microphones require 3 pieces of „AA„ size
batteries to operate.Please insert the batteries according
to the correct polarity indication. Remove the cover to
open the battery compartment as indicated in Fig.4.
Caution
Many batteries are known to have leakage problem of conductive and corrosive liquid. Please observe the rule to remove the batteries if they are not to be used for a period of a few days.
Due to various unstandardized sizes ( diameters ) of „ AA „ batteries, this battery compartment is
designed to accommodate the most commom Alkaline batteries only.

4.1. Channel selection and gain
Channel selector and gain adjustment are hidden in the designated cover in the front as shown in
Fig. 7. To make channel selection and gain adjustment, please press the designated cover and flip
it open. Channel selection can be made by rotating the selector with a small screw driver.Gain adjustment for Lavalier and Headset microphones can be done by adjusting the MT switch, whereas
GT switch is for the gain adjust of electric Guitar and other high impedance line level inputs.
