adjusting the Squelch
In normal operation, each 4W-1KU
QUAD 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 LED
Diversity a/B Indicators
(2)
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, the receiver signal
and the
RF Signal Meter (12)
and one of the
LED Diversity A/B Indicators is 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 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 4W-1KU QUAD receiver has an
aF Peak
leD (3)
display for each receiver and each
works independently per channel. The AF Peak
LED occasional flickering green on normal or
loud inputs to the transmitter is normal. If the
AF Peak LED lights green continuously, you
might overload the system. Decrease the
audio level input to the transmitter or overload
distortion sound may result.
Connecting the audio Outputs
The 4W-1KU QUAD receiver has one
Unbalanced audio Out (17)
(adjustable Line
level) SUM audio output and four
Balanced
Mic Out (15)
(fixed level) XLR jacks and each
output works independently per receiver.
The Unbalanced Audio Out is controlled
by
(Up) or (Down) Buttons
(7)
for volume
control and the receiver
Sum Volume Meter
(11)
will indicate the level selected. For
unbalanced output, plug an ¼” mono (Tip/
Sleeve) audio cable into the
Unbalanced
audio Out (17)
and plug the other end into
your mixing board or amplifier. When
using the BT-1KU instrument transmitter
system, connect the Unbalanced Audio Out
directly to your instrument amp or preamp.
At maximum receiver volume setting, as
indicated by the Sum Volume Level display,
the system output is approxi4dB
higher than a direct cord-to-amp connection.
Note that all 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 Balanced Mic Out sockets must be
used. However, 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 each
receiver and plug the other end into your
mixing board or amplifier inputs accordingly.
Note:
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 4W-1KU QUAD 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 four receiver unit, four
transmitters on separate frequencies can be
utilized, one with each receiver.
