The power and performance of four stereo amps

Now that you've installed a whole-home audio system — maybe you've got speaker pairs in the kitchen, bedroom, home office, and backyard for great listening everywhere — you need power. Now, you could invest in four separate stereo amplifiers, but the cost would be high and four independent components would take up a large amount of space and generate unnecessary heat. Combining the power and performance of four independent stereo amplifiers into one compact component, Sonance presents the 875D SE digital amplifier. With its 75W x 8 channels (four stereo pairs) and digital power amplification, the 875D SE fuels your whole-home audio with clean, high-fidelity power.

Digital bridging

For unique whole-home audio applications where you need to drive serious power to only a couple of channels, the Sonance 875D SE offer Class T digital power amplification with Digital Power Processing. Class T circuitry allows the 875D SE to operate with any of its four pairs of channels in a bridged mode, providing up to 300W 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.

Sound enhancement with BBE

The Sonamp 875D SE incorporates BBE Sound Enhancement, improving the presence and detail of speakers, especially at lower 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. Each zone in the 875D SE has individual controls that set the BBE enhancement to +9dB, +6dB or OFF.

Connectivity options

The 875D SE's multiple input connections (Direct, L/R & Aux) and buffered line outputs provide the connection flexibility that Sonance owners have come to expect. Each zone has its own 12V input and output triggers and defeat-able 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.

Take control

Serial control capability (via RS-232) allows the 875D SE to be directly controlled by a variety of top-line 3rd-party control systems. In addition to controlling an extensive array of operational features, the serial provision also allows the 875D SE?s operation to be monitored from a remote location. Front-panel LEDs provide Power ON/OFF indication for the amplifier, and Zone ON/OFF, BBE ON/OFF and Fault status indication for each zone.
