TOA W-906A UL 6-Channel In-Wall Mixer and Power Amplifier, 60W

The TOA W-906A Mixer Power Amplifier controls and mixes up to six independent input signals plus two inputs with use of an expanding kit WE-2. The W-906A delivers up to 60 watts of output power. Twenty one optional accessory modules are available to allow the W-906A amplifier to be configured for a variety of applications. Edge connectors on the rear of the units permit TOA modules to be easily inserted for use.

Modules include the M Series microphone preamplifiers, available with muting, remote volume control, voice gate and compressor options. The U Series auxiliary preamplifiers, available with muting, remote volume control and compressor options. The B Series bridging transformers, available with muting option, the L Series line matching transformers, available with muting option, the S Series signal generator modules and the I-01S Exes interface paging module. Also available are the T-01S module featuring 600-ohm balanced output capability and the T-02S module featuring auxiliary input and balanced line output for music-on-hold.

The W-906A Mixer Power Amplifier has a built-in one-octave graphic equalizer with 9 bands to tailor sound system frequency response to room acoustics, reducing feedback tendencies and improving intelligibility. A built-in compressor circuit is provided to protect the output level from distortion as a result of excessive input and keep it constant. The compressor’s threshold level can be adjusted.

The W-906A Mixer Power Amplifier has output terminals to match 4- or 8-ohm speaker systems, or a speaker distribution system may be connected to the 25 or 70-volt terminals. User’s (blank) space is provided for additional functions to be made by the customers. The expanding kit (optional) may be loaded in this space when the number of inputs is increased. Protection against tampering is assured by means of a keylocked hinged door.

The W-906A can be mounted in any 4" wall with use of the BX-9F Flush Mounting Back Box. Wall mounting is also possible with use of the BX-9S Surface Mounting Box.
