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.
