英国 Cambridge Audio/剑桥Azur 851A 合并功放
Azur 851A Integrated Class XD amplifier 特点
Class XD™ amplification designed to eliminate crossover distortion at low signal levels
New balanced volume topology controllable in 1dB steps, giving very fine control, and superbly accurate channel balance
Audiophile grade oversize toroidal transformer and substantial extruded heatsink allowing 2 x 120 Watts RMS into 8 Ohms or 2 x 200W into 4 ohms.
Separate transformer taps for left and right channels, twin rectifiers and separate PSUs for dual mono operation of the left and right power amplifiers
A separate toroidal transformer supplies the preamp making the 851A effectively a Pre and Power amp combination in one box
CAP5 protection technology for trouble free operation
Acoustically damped full metal chassis with thick brushed aluminium front panel
Customisable front panel display
Balanced and unbalanced analogue audio inputs for superior connectivity
RS232 controllable
Eco-friendly <0.5W Standby power consumption
Available in black and silver finishes
