Nady Systems SW-1KU Operating the BT-1KU Bodypack Transmitter, Instrument Use BT-1KU/GTonly

at -10dB for LT/HM and 0dB for GT. These settings are optimal for most applications.

For normal operation, the transmitter should have the same Group/Channel as displayed on the receiver. The default factory setting is Group 01 (Receiver 1) and 02 (Receiver 2), 03 (Receiver 3) and 04 (Receiver 4), Group 05 (Receiver 5) and 06 (Receiver 6), 07 (Receiver 7) and 08 (Receiver 8) for all receivers. After programming is finished, close the battery compartment door, ensuring that it latches. The BT-1KU is now ready for use.

Note: If you are using multiple transmitters at the same location, set up the first transmitter and leave it ON and keep it 3 ft. away from the receivers. Then start AUTO-SCAN on the second receiver. This avoids duplicate selection of the same channel as already selected for the first receiver.

If you are not satisfied with a channel after scanning, repeat again anytime for selecting another free channel.

Operating the BT-1KU

Bodypack Transmitter

During normal operation with the unit powered on, the transmitter power level can be changed by sliding the RF Power Switch

(44)to “H” to increase the transmitted RF power (for longer range) or to “L” to decrease the RF power (reduced range). This is a useful feature as the “L” setting increases battery life and also optimizes the number of channels that can be used simultaneously in a given location. Use this setting for normal use not requiring maximum operating range. A range walk test before use will determine which setting is best for your application.

The Power Off/Mute/On Switch (38) has three positions and functions as a power on/off and an audio mute on/off switch. After the unit is powered on, slide the power switch to the “ON” position to un-mute the audio.

With Power Off/Mute/On switch in either in “MUTE” or ON” position the receiver’s RF Signal Meter (12) and one Diversity A or B

(3)indicator should now be on, indicating a received signal from the transmitter. When ready to transmit audio, slide the power switch to “ON” position to un-mute. To mute, slide the power switch to “MUTE” again. Adjust the volume of the receiver per Connecting Audio Outputs section above.

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

The RF Signal meter and the Diversity A/B indicator on the receiver’s LCD display should be “On” in normal operation.

Instrument Use (BT-1KU/GT only)

Secure the connection of the GT (instrument) cable by lining up the slot of the 3.5mm mini locking Input Jack (37) connector and turning the ring to securely lock in. When ready to play, slide the Power Off/Mute/On Switch (38) to “ON” position to un-mute the audio. Adjust the volume lower on the receiver’s Unbalanced Audio Output (17) for one-to-one unity gain with a hardwired cord or select up to an added

4-5dB boost by leaving the receiver volume to maximum for normal use with guitars and bass guitars. Note this function is best when using two transmitters for switching during performance as these is only a single mixed output from the two receivers. If an individual output per receiver is desired, use the XLR Mic Outputs (15), noting that those are only fixed Mic level outputs.

Note: The audio level should be adjusted on the instrument as when using a hard-wired cord. For most applications the transmitter’s Input Volume Level (32) should be set at 0dB for optimal performance. Use attenuation levels (-10dB, -20dB, -30dB) only for higher output instruments, such as bass guitars with active pickups, and then only if needed for cleaner sound.
