System vs set
Because the terms system and set can be used interchangeably, thereby
causing confusion, this manual refers to a set as a single mated pair of
one transmitter and one receiver. Whereas a system is the collection of
multiple wireless sets and antenna distribution items.
Set
A pre-packaged combination of receiver, receiver antenna, receiver
power supply, transmitter, transmitter input device, and other supplied
accessories. For example, if you purchased an RE3-ND76-5L, the
manufacturer considers it a set. Also it is the basic hardware
combination of a mated transmitter and receiver.
SET
A multi-purpose menu navigation key which functions as an enter key, a
menu advance key, an item select key, and a save or store key.
Scroll
To navigate up and down menus or item options using the ▲ and ▼
buttons.
Group
A predefined combination of intermodulation-free frequencies.
Channel
As it relates to frequencies within a group, it is the exact frequency a set
can be tuned to.
As it relates to a multi-channel system, it is the quantity of unique paired
transmitters and receivers. For example, a multi-channel system
consisting of eight receivers and eight mated transmitters is said to be
an eight channel system.
Intermodulation
The adverse reception interference that occurs when two or more non-
coordinated frequencies produce harmonics which disrupt reception of
one or more channels.
SYNC
The operation of synchronizing a receiver’s transmitter data to the
mated transmitter.
RX
Abbreviation for receiver.
TX
Abbreviation for transmitter.
RF
Abbreviation for radio frequency. RE3 is an RF wireless microphone set
operating in the UHF radio spectrum.
UHF
Abbreviation for ultra-high frequency, and is the term when applied to
wireless microphone products as the portion of radio spectrum shared
with UHF television signals between 470MHz and 865MHz. Those limits
vary by country where used.
MHz
Abbreviation for megahertz denoting frequencies measuring in the
millions of cycles per second. A common reference for wireless
microphones using this shortened numerical expression could be
