General Description; Features; Handling Precautions - Toa WT-4800 Mode D'emploi

2. GENERAL DESCRIPTION

The WT-4800 Wireless Tuner is designed for use on the UHF band, and suitable for vocal or speech
reinforcement applications. It features a compander circuit which minimizes the influence of ambient noise.

3. FEATURES

• 64 different operating frequencies (4 banks x 16 channels)
• Optimized PLL-synthesizer drastically minimizes the oscillation frequency drift resulting from the ambient
temperature changes.
• The Scan function indicates available idle channels and is useful when changing the operating frequency.
• The LCD screen indicates the current operating frequency, as well as RF and AF levels.
• Antenna distribution outputs and audio cascade inputs facilitate connection of another unit to build a dual-
channel system.
• Compact size and high reliability

4. HANDLING PRECAUTIONS

• Make sure that the power switch is switched OFF after use.
• When mounting in an equipment rack, select the position which does not expose the unit to high
temperature.
• When installing, keep the unit as far away as possible from fluorescent lamps, digital equipment, personal
computers, and other equipment which generate high frequency noise.
• Only the same bank wireless systems can be used in the same location. Avoid using the systems in
combination with those of different banks because interference or noise could be generated.
• Wireless tuners to be installed in the same location must differ from each other in channel number. Setting
them for the same channel number could result in noise. Wireless microphones must be identical to wireless
tuners in both bank and channel numbers.
• When using two or more wireless microphones, keep them at least 50 cm away from each other to avoid
malfunctions or noise.
• Keep the wireless microphone at least 3 m away from the receiving antenna. Using the microphone in close
proximity to the antenna could result in malfunctions or noise.
• Be sure to connect at least two receiving antennas (one each for Channels A and B).
