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 652.725MHz (six-hundred fifty-two
million, seven hundred twenty-five thousand cycles per second).
Multi-channel
system
A system made up of two or more sets where each set is tuned to a specific
frequency (channel) which does not interfere with the operation of other
