ITEC 5100 WIRELESS SYSTEM

With the ITEC 5100 you have a modern and professional wireless microphone system in the UHF domain
available. The receivers (as the module receiver and the integrated 19” version) are true diversity receivers,
ensuring a high operating distance and an undisturbed reception without short-term loss of communication.
The innovative “pilot tone technique” offers a reliable protection against interferences caused by jamming
transmitters and prevents switching noise during on-off operations of the sender.

1. Introduction

Congratulation in owning one of these state-of-the-art Synthesized 100 channels frequency agile UHF high
band professional wireless receivers.

The system contains the following components:

Receiver Module Receiver Hand-held Transmitter Pocket Transmitter
ITEC SDR-5100 ITEC SDR-5100M WM-5100 WT-5100

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 refl ection. The
transmitter should also be at least 1m away from
a wall or metal surface to minimize refl ection. 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, Spotlights with serious connection unit,
neon light as well as large metal objects.

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 Fig.2.

2.1.3. Rack Mounting

The ITEC SDR-5100 receiver is suitable for installations within 19” racks. For this purpose 2 different mounting
adapters are available (see picture 3 and 4)

Picture 4: Installation kit for two receivers (consisting of 2
short angle brackets and a union joint)

Picture 3: Installation kit for one receiver (consisting of a short and a long angle bracket)

2.1.4. Volume adjustment, channel selection and squelch set-up

2.1.4.1 Lock / unlock operation

In case the receiver is locked (as shown in the display), an unlock operation is required, before any adjustments
of the set-up are possible. Press the PgUp or the PrDn button for several seconds: After carrying out
the adjustments the locked mode can be reached in the same way again.
