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.
