Operation is subject to the condition that this device does not cause harmful interference. Operation is subject to the following conditions: 1) This device may not cause harmful interference and 2) this device must accept any interference received, including interference which may cause undesired operation. The circuits inside the receiver and transmitter have been precisely adjusted for optimum performance and compliance with federal regulations. To do so will void the warranty, and may cause improper operation. · For use only where there is no channel 13: Multi-channel Systems Following are groupings of frequencies suggested for multi-channel wireless systems. · For use where TV channels 7, 9, 11 and/or 13 are operating: 8D-8M-8S-10C-10J-10W-12L-12S-12V Traveling frequencies T2, T3 and/or T8 may be used with any of the above frequencies except for: 8D, 8M and 10C. · For use where TV channels 8, 10 and/or 12 are operating: 7G-7I-9F-9Q-11G-11S-13Q or 7G-7I-9F-11G-11S-13B-13Q RECEIVER Receiving System Image Rejection Signal-to-noise THD Sensitivity Audio Output Unbalanced Balanced Dual independent receivers, automatic switching diversity reception 60 dB . 80 dB at 10 kHz deviation (IEC-weighted) 1% (10 kHz deviation @ 1 kHz) 10 µV for 60 dB S/N (IEC-weighted) 350 mV (at 1 kHz, ±10 kHz deviation, 10k ohm load) 220 mV (at 1 kHz, ±10 kHz deviation, 10k ohm load) 1/4" phone jack XLRM-type 12-18V DC, 350 mA, with provided AC adapter 16. 93" (430. 0 mm) W x 1. 92" (48. 8 mm) H x 7. 28" (185. 0 mm) D 5. 5 lbs (2. 5 kgs) Two whip antennas, rack mount adapters, AD1205A AC adapter PWS-MIC HANDHELD TRANSMITTER Traveling frequencies T2, T3 and/or T8 may be used with any of the above frequencies with no interference problems. ACCESSORIES PWS-RMA Rack-mount antenna kit brings antenna inputs to the front of receiver for ease of setup. This indicates that maximum transmitter modulation without significant distortion has been reached. (When using a microphone, return the GT control setting to minimum. ) After adjusting input levels, return the screwdriver to its clip and reinstall the battery cover. No further transmitter gain adjustments should be needed, as long as the input device and the acoustic input level are not changed. PWS2000 SERIES VHF DIVERSITY RECEIVER Fig. C HANDHELD TRANSMITTER Unscrew the lower body cover and slide it downward, exposing the screwdriver and gain trimmer (Fig. Remover the screwdriver and gently turn this gain trimmer control to its full counter-clockwise position. With acoustic input to the microphone at typically-loud levels, carefully turn the trimmer control clockwise while watching the receiver's AF Peak indicator. This indicates that maximum transmitter modulation without significant distortion has been reached. Return the screwdriver to its clip and close and secure the lower body. (Make certain that the white "battery keeper" arm is inside the body. ) No further transmitter adjustments should be needed, as long as the acoustic input does not change significantly. Fig. [. . . ] If the receiver output is set too low, the overall signal-to-noise ratio of the system may be reduced. Adjust the output level of the receiver so the highest sound pressure level going into the microphone causes no input overload in the mixer, and yet permits the mixer level controls to operate in their"normal" range (not set too high or too low). Remove the battery if the transmitter is not to be used for a period of time. In multiple-system applications, set the battery-save switches on "L" (low) is possible, to reduce the chance of intermodulation problems. REAR PANEL CONTROLS AND FUNCTIONS 8. [. . . ]
