Our take on the NAD C 245BEE

by Jim Richardson
NAD

Clean power for a range of applications

This versatile, space-saving amp provides the superior sound and excellent value NAD is known for. Use it to power music zones in your multi-room audio system, bi-amp stereo speakers, or add surround channels to your home theater system.

Handy hook-up options

With three turn-on options (front panel switch, 12V trigger control, or signal-sensing), this amp easily adapts to any type of installation. Multiple C 245BEEs can share the same input signal, giving you the capacity to configure music zones that perfectly suit your listening spaces.

It's all about sound quality

While its versatility sets it apart, the audio performance of C 245BEE is very much in line with the rest of NAD's Classic Series. The power supply features a custom toroidal transformer that minimizes noise and helps to control unwanted speaker cone movement. In the absence of background noise, the subtle details of your music emerge, enriching your listening experience.

Features

Overview: The C 245BEE is a flexible 4-channel amplifier, divided into two discrete 2-channel amps in one chassis (A and B). Each side is individually bridgeable, so it can be used to power four speakers, three speakers, or two speakers.

Discrete Inputs: The A and B channels have separate inputs; both also have Loop Through outputs for connecting another amplifier. The output is identical to the corresponding input.

Auto Turn-on: The C 245BEE can be turned on automatically one of two ways; +12 volt trigger from another component or by sensing an input signal. The automatic function can also be turned off so the amp is turned on/off manually using the front panel switch.

Controls

Rear Panel:

  • Bridge Mode: switch between stereo and mono amplifier output; the A and B channels have individual mode switches
  • 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 0.45" wide, and bare wire up to 12 gauge; there are four speaker outputs, A (left and right) and B (left and right)
  • Signal Inputs: two sets of stereo RCA inputs, A channels and B channels
  • Line Outputs: two sets of stereo RCA inputs, A channels and B channels; output is identical to the corresponding input
  • 12 Volt Trigger: 3.5mm jack; 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)

Great Amp at a good price

Written By AndrewM, Windsor, Ontario on Wednesday, June 19, 2013
Crutchfield Customer Review (What's this?)
 
I bought this amp to support my Turntable. I have a Rega RP3 going into a Bellari phono pre-amp which in turn is now connected to the NAD C 245BEE. This replaced an older sony integrated amp that was pretty much dead. I currently have it powering a pair of Infinity floor speakers that I inherited from my dad. Hook up was extremely easy. Immediately as soon as we put on an album we noticed a much robust and clear sound. Mid range is excellent and it definitely has the power to full a large room. We don't ever turn the preamp over 20% of full volume. Only downside i can see is that I feel i need a more roust preamp which will allow a bit more contol of treble and bass.
Pros:
easy set up powerful great sound
Cons:
not really a con but need the proper supporting preamp.
