Stereo Power Amplifier
The new Sonamp 875D SE is a hybrid 8-channel amplifier that combines the efficiency of digital amplification with proven analog
power supply technology, delivering unprecedented efficiency, compactness and high-end sound quality in an extremely flexible
and useful package. Serial volume commands add flexibility for second zone use.
Class T digital amplification with Digital Power Processing® allows the 875D SE to deliver high power (75 watts @ 8 ohms and 140
watts @ 4 ohms x 8 channels) in an exceptionally small (2U rack height) package, with all the musical sound quality Sonamps have
become known for. Unlike conventional digital amplifiers, the 875D SE’s Class T circuitry allows it to operate with any of its four
pairs of channels in a bridged mode, providing 300 watts x 4 channels into 8-ohm loads. Four independent power supplies (one
for each zone) use trusted analog technology to assure that each zone will receive plenty of current regardless of how hard any
other zones are being driven.
Serial control capability allows the 875D SE to be directly controlled by a variety of top-line 3rd-party control systems. In addition
to controlling volume and an extensive array of operational features, the serial query provision also allows the 875D SE’s operation
to be monitored from a remote location.
The Sonamp 875D SE incorporates BBE Sound Enhancement that improves presence and detail of speakers, especially at lower
power listening volumes. This makes it particularly effective at improving the sound quality of distributed audio systems playing
background music. BBE also restores clarity and definition (or focus) to spoken voices, making paging systems easier to understand
without having to run them at high volumes.
The 875D SE’s multiple input connections (Direct, L/R & Aux) and buffered line outputs provide the connection flexibility that
Sonance dealers have come to expect. Each zone has its own 12V input and output triggers and defeatable auto-on signal sensing
that help maximize power management for the channel configuration in use at any time. Recessed front-panel controls allow
tamper-resistant adjustment of each channel’s input level, and of each zone’s auto-on sensitivity.
Features
Extensive serial control capability gives you the ability to integrate the 875D SE into any number of top-level control
systems, providing
• global, zone-specic or channel-specic commands for volume and muting
• commands for setting BBE Sound Enhancement
• automatic temperature and fault alerts
• query commands allow the user to poll the amplier so it will report its operating conditions back to the monitoring station
