Adjusting the Squelch
In normal operation, each 2W-1KU receiver’s
Mute Control (16) works independently and
should be adjusted clockwise (CW) to the
minimum RF squelch setting at which the
RF Level Meter (12) and one of the Diversity
Indicators (8/13) will remain on while your
transmitter is in normal use, up to the
maximum operating range anticipated in use
for your application. However, in areas of
high RF activity, the Mute control may need
to be adjusted counterclockwise (CCW).
If the transmitter is off and the RF Signal
Meter (12) and Diversity Indicators (8/13) are
flickering or stay on continuously, the Mute
level should be adjusted higher level CCW
(counterclockwise for less mute sensitivity
level) to stop the flickering. Be careful not
to adjust a too high CCW setting as this
may reduce the operating range to below
what is needed. A range walk test will help
in selecting the proper level. If the range
is not critical, note that a counterclockwise
(maximum mute) setting will also yield
a quieter mute function, which might be
desired in certain applications. The Mute
level is factory preset at clockwise (CW) for
maximum sensitivity and operating range
(i.e. clockwise (CW) for minimum squelch
level—maximum usable range).
Audio Level and Peak LED Indicator
The 2W-1KU receiver has two 5-segment
AF/Peak LEDs Displays (5) and each works
independently per receiver. The AF/Peak
LEDs light up sequentially, indicating
the level of the audio signal from the
transmitter. Occasional flickering of the
top (red) Peak LED on loud inputs to the
transmitter is normal. If the Peak LED lights
continuously decrease the input audio level
to the transmitter or overload distortion
may result.
Connecting the Audio Outputs
The 2W-1KU receiver has one Unbalanced
Audio SUM Out (18) adjustable line level
audio output and two Balanced XLR Mic
Out (17) fixed level jacks and each works
independently per channel. The Unbalanced
Audio Out is controlled by (Up) or
(Down) Buttons (4). The receiver Volume
Display (12) will indicate the level selected.
For unbalanced output, plug a ¼” mono
(Tip/Sleeve) audio cable into the Unbalanced
Audio Out jack and plug the other end into
your mixing board or amplifier. When using
the BT-1KU instrument transmitter system,
connect the Unbalanced Audio SUM Out
directly to your instrument amp or preamp.
At maximum receiver volume setting, as
indicated by the Volume display, the system
output is approximately +4dB higher than a
direct cord-to-amp connection.
Note: Both receivers’ output will be mixed together
as per the individual receivers’ volume settings
as selected by the up/down volume controls.
If separate signals are required for each instrument
then the XLR outputs must be used, however, note
they are not line level or adjustable. The SUM out
is best utilized for switching between separate
transmitters during performance with only one audio
signal at a time fed to the instrument amplifier.
For balanced output, plug an audio cable with an
XLR connector into the XLR Balanced Mic Out
socket for each receiver and plug the other end into
your mixing board or amplifier inputs accordingly
As when making any connection, make sure
the amplifier or mixing board volume is at the
minimum level before plugging in the receiver
to avoid possible sound system damage.
Your 2W-1KU receiver is now operational
and ready to use. Once you have completed
the above steps, proceed to the following
instructions for the HT-1KU handheld or
BT-1KU instrument transmitter.
Note: Only one transmitter can be used with one
receiver. It is not possible to use two transmitters
on the same frequency and mix the output of
these transmitters into one wireless receiver.
However, as this is a two receiver unit, two
transmitters on separate frequencies can be
utilized, one with each receiver.
