Design and Features
Power
The Sonamp® 875D SE is a hybrid amplifier that combines digital amplification with analog power supplies. Its Class T amplifier with Digital Power Processing™ technology delivers the high efficiency of digital (Class D) amplification with the superior sound quality of analog (Class
AB) amplifiers. This allows the 875D SE to deliver high power (75 watts RMS per channel @ 8 ohms x 8 Channels) in an exceptionally small (2U rack height) package. And unlike conventional digital amplifiers which cannot operate in bridged configuration, the 875D SE’s Class T circuitry allows you to operate it with any of its four pairs of channels in a bridged mode, providing 300 watts x 4 channels into an

Each zone in the 875D SE has individual controls that let you set the BBE enhancement for that zone to +9dB, +6dB or OFF. The factory default setting is +6dB.
Inputs and Triggers
Multiple audio input connections (DIRECT, L/R & AUX) and buffered line outputs make your 875D SE extremely flexible, so you can connect the amplifier in a variety of ways depending on your particular system’s configuration. The Illustrations on pages 15 – 20 show the 875D SE being used in several different possible system configurations. Each zone has its own 12V input and output triggers and defeatable
