Introduction
The Multi-Rx
TM
was designed to provide a flexible way to monitor and control the
receive audio of multiple receivers. The Multi-Rx
TM
works with any radios
including VHF/UHF scanners and transceivers and HF receivers and
transceivers. The Multi-Rx
TM
provides selective monitoring of one to six radios
while allowing the operator to position the audio from each radio at distinct
locations in the audio field. Additionally, all radios can be muted (silenced) at the
push of a button. Provision is included for manual or automatic control of an
external digital or audio tape recorder. Any combination of the six radios can be
recorded and you can even record both sides of a QSO (provided your
transceiver has a “monitor” function). A unique
Spatial
mode lets you use only
two speakers but gives spatial separation of the audio from each radio which is
equivalent to having 6 individual speakers, one for each radio. In the
Normal
mode, receive audio can be selectively positioned left, right or center in the audio
field.
The Multi-Rx
TM
will benefit just about any ham shack. Its flexibility and versatility
make it ideal for contest stations, emergency operations, satellite stations,
repeater sites, mobile communications vans and any radio communications
environment.
Connecting to the NCS-3240 Multi-Switcher
For complete station control, the Multi-Rx
TM
was designed to connect to the NCS-
3240 Multi-Switcher. The Multi-Switcher provides microphone switching for
transmitters as well as other functions. When both are used together, complete
transmit and receive control of multiple radios is achieved including automatic
muting of all radios when transmitting. There is also the ability to mute all radios
except the one being used. This feature is useful in HF setups where the
operator wants to monitor the transmitted audio using a radio’s built-in “monitor”
function.
NCS provides a full range of cables for connecting the Multi-Rx
TM
to the Multi-
Switcher as well as microphone cables for most radios. Consult the NCS
website or call NCS to determine the correct cables for your specific
configuration.
