Page 4: System Overview
YSTEM VERVIEW The Williams Sound WIR TX10 Infrared Transmitter uses invisible infrared (IR) light waves to broadcast speech or music to wireless infrared receivers. The TX10 accepts a balanced or unbalanced line level audio input and emits an invisible infrared 95 kHz or 250 kHz frequency throughout the listening area. Infrared receivers detect the transmission and convert the light signals back into audio signals. -

Important: Remember to point the transmitter towards the listening audience! Remember: opaque objects block infrared light. Thus, transmitters cannot be concealed behind opaque walls, curtains, etc. Neither should transmitters be used in areas of extreme high or low temperatures, humidity, or chemical environments. ® Williams Sound Helping People Hear... - Page 7 FIG 3b: Vertical Beam Spread Minimum receiver RANGE when operating with a TX8 or TX10 transmitter in Single Channel Mode.

The TX10 must be supplied power from a Limited Power Source as defined by EN 60950:1992; Clause 2.11. Units operated from 120 VAC must use Williams Sound part number TFP 010. Units operating from 230 VAC must use Williams Sound power supply part number TFP 027/UK. - Page 12 UDIO OURCE ONNECTION The WIR TX10 accepts audio signals from balanced or unbalanced line level outputs, transmitting audio with excellent fidelity. Therefore, be sure to connect its input to the highest quality audio source your system can offer. Step 1: Determine the length of cable needed to reach from the audio source to the TX10 Transmitter.

- Page 14 UDIO NPUT The WIR TX10's input circuit is constructed with a differential amplifier, providing better performance than that available using a transformer. It is fully protected from RFI/EMI. Both balanced and unbalanced line level signals can be accommodated. The minimum acceptable level is approximately 100 mV, and the maximum level before clipping is approximately 10 V.
