will ﬂash for ﬁve seconds or press the Set

button to conﬁrm the selection and the

display will return to the main menu. For

detail how to IR Sync the TX, see IR Sync

Programming in Programming sections of

HT-1KU and BT-1KU transmitter sections.

Adjusting the Squelch

In normal operation, each 8W-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 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 (2) 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 8W-1KU 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

8W-1KU receiver has one Unbalanced Audio

Out (17) (adjustable Line level) SUM audio

output and eight 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 a 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 approximately +4dB 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.
