35W mixer amplifier with 3 inputs applicable for systems demanding a broad range of features and high energy efficiency. 2 outputs power amplifier zones are provided, 35W (zone 1) and 2W (zone 2). Zone 1 mixer is located on the front-panel providing user level and tone controls for the 35W amplifier output. The tone controls adjust the equalization at the zone 1 amplifier output. The zone 2 mixer on the rear panel provides level trimmers normally set by the installer to provide music-on-hold and/or for background music in a small zone equipped with an 8ohms speaker.
