Key Features
• Amplification for premium sound from a reliable, high
quality Class-D amplifier provides optimized performance and
premium sound quality through the use of internal digital signal
processing
• Installation made simple with set up done locally from the
front and rear panels of the amplifier—no computer is required
• Opti-voice® paging provides smooth automatic transition
between the music and page signals
• End-user friendly front panel allows users to connect
devices easily, make tonal adjustments or select between
two sources.Optional wall mountable Bose Volume control
with A/B switch userinterface allows volume and source
selection controls to be placed awayfrom the amplifier for user
convenience
