System Operation W-1KU Receiver Buttons Function The Power Button (12) is used to turn the receiver on or off. When the button is pressed, the lit blue backlight on the LCD Display (2) indicates the receiver is on. Press the Power button again to turn off the receiver. The backlight on the LCD will turn off indicating the receiver is off. At power-off the W-1KU receiver will store the last settings entered and re-display them at power-on. It can be reprogrammed to any new Group/Channel, or Volume level.
Installing Antennas Install antennas by connecting the two Antennas (19) included with your system to the two RF Connectors (18) located on the back of your W-1KU receiver. The optimal positions of the antennas are 45 degrees from the receiver and 90 degrees from each other. For maximum range, it is always best to maintain a line-of-sight (no obstructions) between the receiver antennas and the transmitter at all times whenever possible.
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: 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 W-1KU receiver is now operational and ready to use.
a radio signal on the same channel as the receiver. The Signal Strength and Diversity Indicators on the receiver’s LCD display will then light up, indicating that the IR link is completed. If no action is taken during the three seconds of active data transfer, the receiver and the transmitter units do not link and transmitter’s previous program channel remains unchanged. Note: The IR link is infrared light and thus works best when this data transfer is accomplished in a light-shielded or darker environment.
be on, indicating a received signal from the transmitter. Adjust the volume of the receiver per Connecting Audio Output. Note: Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement. Note: The RF Signal meter and the Diversity A/B indicator on the receiver’s LCD display should be “On” in normal operation.
more at three seconds, indicating that the IR transmission is over. Upon successful data transfer (usually in less than two seconds) the transmitter’s backlight will light up and the transmitter will transmit a radio signal on the same channel as the receiver. The Signal Strength and Diversity Indicators on the receiver’s LCD display will then light up, indicating that the IR link is completed.
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 (42) 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.
Specifications SYSTEM OVERALL SPECIFICATIONS Operating Frequency Range 672MHz-697MHz (US) Freq. Synthesized (1000 channels switchable) 25kHz/step PLL system frequency stability <0.005% Frequency Response 30Hz-18kHz +/-3dB Dynamic Range 120dB Harmonic Distortion <0.
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.
Miscellaneous Tips • For optimum operation with external antennas, low loss RF shielded cable should be used and the length of the cable should not exceed 10’ (3 m). • The receiver antennas should be kept away from any metal surfaces whenever possible as they can reflect away or shield the incoming RF signal. • If the receiver’s volume control is set too high, it may overdrive the input of the attached audio mixer, causing distortion.
