Applications. It operates on dual 2.3/2.8 or 3.3/3.8 MHz selectable frequencies - ideal for high quality audio programs such as music, theater and audio description. The WIR TX90 will accept any line level, balanced or unbalanced audio inputs, and includes adjustable tone and volume control. Infrared receivers detect the trans- mission and convert the light signals back into audio signals.
RX22-4 receiver, in single channel mode, the WIR TX90 can achieve a coverage area of 28,000 ft (2,600 m ). In four channel mode, the WIR TX90 divides its power among the four signals to achieve a coverage area of 11,000 ft (1,022 m ).

TFP 027-02: 230VAC, UK Mains Plug NOTE: The WIR TX90 transmits when a baseband signal is present, and will shut off immediately when no baseband signal is present. This auto shut-off feature preserves the life of the infrared LEDs and reduces power consumption.
The WIR TX90 offers two sets of carrier frequencies for Channel A and Channel B: 2.3 and 2.8MHz or 3.3 and 3.8MHz. The WIR TX90 is preset to 2.3 and 2.8 MHz, which are the most commonly used. Move the slide switch to select a pair of operating frequencies.
Make sure the input audio signal is connected to the WIR TX90. To adjust the audio input level, first activate the channel(s) you want to adjust by pressing the “CHANNEL” button, then press the “VOLUME” button.
For larger facilities, additional emitter panels can be used to increase the overall coverage area. In these cases, we recommend using the WIR TX9 slave emitter in tandem with the WIR TX90. The WIR TX90 can drive multiple WIR TX9 emitters at one time. Each TX9 emitter will require its own power supply.
AFETY CAUTION! Williams Sound receivers are designed to amplify sounds to a high volume level which could potentially cause hearing damage if used improperly. To protect your hearing and the hearing of others: Make sure the volume is turned down before putting on the earphone or headphone before adjusting the volume to a comfortable level.

If none of the receivers work, check to see if the power and audio input cable are connected to the transmitter and that the WIR TX90 “Power On” and Channel A or B “On” indicator is illuminated. Check to see if the transmitter is connected properly to the sound system. The audio level indicators should flash on channels that are selected.
