System Overview
The 7100DX Quad-RAK dual tuner diversity UHF wireless microphone system is designed
for applications where multiple wireless microphones will be used simultaneously in a
single venue. The system integrates several features to provide a compact, single rack-
high package; which includes multiple wireless microphone receivers, antenna combiner,
rack mounting and internal power supply.
The Quad-RAK receiver contains up to four modular 100-channel UHF receivers
operating in a single rack space. An active antenna combiner is also included, allowing
all four receivers to operate from a single pair of antennas. Each receiver has 100
preset user selectable frequencies in a micro frequency range of 25MHz. Five macro
frequency groups ranging from 620 MHz to 745MHz are available. Other features
include clear channel scan, tone squelch, and low battery indicators on both
transmitter(s) and receiver(s). Each receiver is available with either the TX-BP900 belt-
pack or the TX-HM900 handheld transmitter (or both).
IMPORTANT NOTE: To take full advantage of the features the
7100DX has to offer, as well as its applications, please take time to read
through the entire manual.
Your 7100DX Quad-RAK documentation package consists of a User’s Manual and a Quick
Start Guide. The User’s Manual has two comprehensive sections,
Controls and
Functions
and Operating Instructions. For an experienced user, follow the steps on
the Quick Start Guide to get your 7100DX Quad-RAK up and running in a matter of
minutes.
