Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.

Features
Soft Clipping: NAD's Soft Clipping circuit gently limits
the output of the C 275BEE to minimize audible distortion when the amplifier
is over-driven. While Soft Clipping can be left on at all times to reduce the
likelihood of audible distortion from excessive volume settings, you can also
turn the circuit off for critical listening if you prefer.
Bridgeable: The C 275BEE can be bridged to a single channel,
more than doubling the power output. When bridged, the minimum recommended
speaker impedance is 8Ω.
A/B Speaker Terminals: The amplifier features A & B speaker
terminals to power two pair of loudspeakers. The amplifier supports 4Ω speakers
when only one pair is connected, however, when two pair of speakers are connected
a minimum impedance of 8Ω is recommended.
Input Select: A switch on the rear panel allows you to set
the input to Fixed or Variable. In the fixed position the input signal is routed
directly to the amplifier; typically used in single amp systems, or when
multiples of the same amp are used. The variable position allows you to adjust
the input level before amplification, useful when matching output levels in a
multi-amp system, bi-amping speakers, or extending the volume control range of
the preamp.
Auto Turn-on: The C 275BEE can be turned on automatically
one of two ways; +12 volt trigger from another component or by sensing an input
signal.
Controls
Rear Panel:
- Input Select: choose Fixed
or Variable (variable allows volume adjustment
using the Input Level dial)
- Input Level: rotary dial;
adjusts volume to match another amplifier
- Bridge Mode: switch between
stereo and mono amplifier output
- Soft Clipping: turn the Soft
Clipping circuit on/off
- Power: master power switch
- +12V/Input Sensing: choose
+12 volt trigger or signal sensing to automatically
turn the amp on
Connections
Rear Panel:
- Speakers: the speaker binding
posts will accept single banana plugs, pin connectors,
spade lugs up to 0.625" wide, and bare wire up
to 10 gauge; there are four speaker outputs, A (left
and right) and B (left and right); when powering two
pair of speakers a minimum impedance of 8Ω is
recommended
- Signal Input: stereo RCA input
jacks
- 12 Volt Trigger: turn the amp
on/off along with another device that has a +12 volt
trigger output
- AC Input: 2-pole IEC power input
for use with included cord (or optional upgraded cord)
