New multi-zone power amp from NAD2 June 2010
The four-channel C245BEE provides a host of system building options, optional bi-amplification and multi-zone compatibility. The latest launch from NAD, the C245BEE can be used to bi-amp stereo speakers, add surround channels to a home cinema, or power music zones to a whole house audio system.
When used with NAD’s C165BEE preamplifier, the C245BEE is said to deliver "more than enough power to drive virtually any loudspeaker", as well as the option to bi-amplify. Connected to the Zone Output of an NAD AV Receiver, the C245BEE can also send different music programs to remote speakers.
Designed by NAD engineer emeritus Bjorn Erik Edvardsen, the C245BEE is rated at 35W/per channel, Minimum Continuous Power, into 4 or 8 ohms, with all channels driven simultaneously, for 20Hz-20kHz, with 0.03% THD (NAD Full Disclosure Power). It can also handle 55W, 85W and 100W Dynamic Power into 8, 4 and 2 ohms, respectively; and 2 x 90W Minimum Continuous Power into 8 ohms in bridge mode.
The C245BEE has three options for powering up: a front panel switch, a 12V trigger control (supported by many companion NAD products), and a signal-sensing ‘auto’ turn-on. In Standby mode, it draws less than 1W thanks to a separate high-efficiency power supply. A ‘vacation’ switch completely disconnects the power.
Each input has a ‘loop out’ feature allowing multiple C245BEEs to share the same signal, which is said to be ideal for elaborate custom installation projects. Pairs of channels can be switched on and off with Speaker A and B switches on the front panel.
Additional refinements include a short signal path from input to output, gold-plated sockets, multi-way binding post speaker outputs, and a detachable IEC power cable.
