Feedback, No or Low Audio | Nady Systems SW-1KU guide

Cautions and Troubleshooting

Feedback

Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement.

Please also note the pickup pattern characteristics of the microphone selected. Unidirectional mics are more resistant to feedback. However, they pick up sound sources best that are directly in front of the mic. Also mics that are farther from the sound source require more acoustic gain and thus are also more prone to feed back than close-source mics such as handheld.

No or Low Audio

If you are not getting audio through the system, carefully re-check all setups. Especially note that the receiver and transmitter must be set to operate on the same RF channel. For BT-1KU bodypack transmitter, also confirm that the Power Off/Mute/On Switch (38) is not in the Mute position. The receiver’s Unbalanced Line Level Out (17) is adjustable so make sure the Volume (11) is set properly.

RF Interference and Finding Open Channels

If you encounter slight receiving interference when the transmitter is far from the receiver (from other than an operating TV station on the same frequency), often it can be overcome by adjusting the receiver‘s Squelch Control (16) (see Adjusting the Squelch). If receiving interference on a selected channel with the transmitter off, you must reprogram the receiver and transmitter to a different channel.

Programming the HT-1KU/BT-1KU to the Selected Channel

To reprogram, you must first find an open channel. To do this, follow the operating procedure outlined in Selecting the 8W-1KU Volume Level / Group / Channel. With the associated transmitter off, scroll through the groups/channels to find one that shows no received signal on the receiver’s RF Signal Meter (12) (no bars). Also, there must be no bars either on each of the three immediately adjacent channels both above and below the selected channel for optimum interference-free operation (i.e. in a field of seven adjacent channel total— with the channel used in the middle). If operating multiple 8W-1KU Series systems simultaneously, repeat this procedure with every new channel being selected, with previously tuned systems all on, both transmitters and receivers.

Please note that wireless frequencies are shared with other radio services. According to FCC regulations, wireless microphone operations are unprotected from interference from other licensed operations in the band. If any interference is received by any Government or non-government operation, the wireless microphone must cease operation or change frequencies. The above statement is valid only for use in the U.S.A.

Note: More bars in the Received Signal (12) icon indicate good signal strength in operation with the transmitter on, but more than 1 bar showing with the transmitter off also indicates the presence of likely RF interfering signals at that location. If this happens, select a different GRP/CH. One bar or less is ideal for interference-free operation.
