IGURE
Power
The 875D MKII utilizes four highly-efficient Bang & Olufsen
ICEpower
®
digital amplifiers that provide 65 watts RMS per
channel @ 8 ohms x 8 Channels. The ICEpower's high
efficiency produces eight channels of high power in a 2U high
package with very little heat generation. This expands
installation options, improves long-term reliability, provides
significant energy savings over conventional amplifier
designs, and helps reduce the system's carbon footprint.
BBE
®
Sound Enhancement
The Sonamp 875D MKII incorporates BBE sound enhance-
ment. The BBE process improves the presence and detail
of speakers, especially at lower listening volumes. This
improves the sound quality of your music, especially
distributed audio systems playing background music. BBE
also restores clarity and definition (or focus) to spoken
voices, which makes paging systems easier to understand
without having to run them at high volumes. Each zone in the
875D MKII has individual controls that let you set the
BBE enhancement for that zone to +6dB, +3dB or OFF.
The factory default setting is +3dB.
Inputs and Triggers
Multiple audio input connections (Direct, L/R & Aux) and
buffered line outputs make your 875D MKII extremely
flexible, so you can connect the amplifier in a variety of ways
depending on your particular system's configuration.

875D MKII 8-CHANNEL AMPLIFIER
The Illustrations on pages 12 – 17 show the 875D MKII being
used in several different possible system configurations. Each
zone has its own 12V input and output triggers and
defeatable auto-on signal sensing that can automatically turn
the amplifier ON. Recessed front-panel controls are tamper-
resistant and let you adjust each channel's input level and
each zone's auto-on sensitivity. Front-panel LEDs tell you if
the 875D MKII's power is on or off, if each Zone is on or off,
and the BBE status and fault status for each zone.
Serial Control Capability
The 875D MKII's RS-232 input lets you use a variety of third-
party serial control systems to control the amplifier.
The serial control provision lets you control almost all of
the 875D MKII's functions, and it also lets you monitor the
amplifier's operation from a remote location.
