Overview:

Our flagship integrated amplifier delivers power, finesse and astonishingly low distortion!

Quite literally in a class of its own, the new CAMBRIDGE AUDIO 851A Class XD integrated amplifier is designed to offer power, finesse and astonishingly low distortion. At its heart lies our own proprietary Class XD technology, which has been refined and enhanced since its inception in the 840 series, allowing even greater musical detail to be delivered to your speaker

Like all Cambridge Audio products, the 851A adheres to our three core values: stunning performance, ease of use and incredible value.

  • Capable of delivering an enormous 120 watts of high-quality power, it benefits from two audiophile-grade toroidal transformers: one for the sensitive preamp section and one for the power stages allowing the 851A to deliver its immense output without stress
  • This incredible speaker-taming amount of power can be precision-controlled with another innovation found in the 851A - the new fully balanced silicon gate volume control, which gives very fine adjustment across the volume range and highly accurate channel-balancing.
  • Because everyone's needs are different, the 851A offers two main types of connectivity: the more commonly found RCA/Phono inputs, plus two pairs of fully balanced XLR connections. Our matching 851C upsampling CD player also features both types of connection, allowing you to connect your system in the very highest quality possible.
  • Speaking of flexibility, you can even control your iPhone, iPad or iPod using the 851 Series remote control when they're docked in our matching iD100 digital dock.
  • Unlike many high end amplifiers which excel in one area over another, we believe the 851A offers the perfect combination of high performance, flexibility and ease of use. It's designed to take your listening experience to an entirely different level and we invite you to audition our best amplifier to date at your nearest Cambridge Audio specialist.

Class XD

  • Class-XD configurations, whilst retaining the high power levels required for truly dynamic performance. It was conceived by our London-based engineering team to combine the best of both worlds from Class A and Class A/B amplifier operation.
  • Class XD (crossover displacement), gives the benefits of pure Class A operation at low levels and eliminates the distortion associated with conventional Class B operation as the fragile audio signal passes though the zero crossing point from transistor to transistor. Distinct from Class AB, XD technology feeds a controlled current into the output stage in such a way that the usual Class B crossover points no longer occur either side of zero volume - the worst possible position in terms of distortion – but displaced to a point where the transfer functions of the transistors are better matched, at a significant output level where it is less audible. The system operates outside of the feedback loop so is not directly involved in the signal amplification itself.
  •  The result is a smooth and linear transition between the two key operating modes, Class A and B.
  • The benefits of this approach give the sonic refinements of Class A operation and the uncompromising efficiency and power of Class B operation. In fact, the new 851A delivers a gigantic 120 watts per channel - enough for the most demanding speaker set-up.

Features:

  • 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
Front Panel Features:

1.Standby/On - Switches the unit between Standby mode (indicated by dim power LED) and On (indicated by bright power LED). Standby is a low power mode where the power consumption is less than 0.5 Watts. The unit can be left in Standby mode when not in use

2. Phones - Allows for the connection of stereo headphones with a ¼” Jack plug.Headphones with an impedance of between 32 and 600 ohms are recommended. When the headphones are connected, the loudspeaker relays are released switching off the output to the loudspeakers (speakers A and B).

3.Speaker A/B - Press to scroll through the speaker sets connected to the loudspeaker terminals on the back panel (speaker sets A, B or A and B). This can be used for listening to an extra set of loudspeakers in another room

4. Mode - Press to switch between Volume and Balance modes. Press and hold to enter the 851A System Configure menu.

5.Infrared sensor - Receives IR commands from the supplied Azur remote control. A clear unobstructed line of sight between the remote control and the sensor is require

6 & 7. Source select buttons - Push the appropriate input selection button to select the source component that you wish to listen to (highlighted by a solid circle on the display). The signal selected is also fed to the Rec Out sockets so that it may be recorded. The input should not be changed whilst recording (but the recorded signal can be checked using the Rec input).

8.Display - LCD used to control the 851

9.Bass and Treble - Press to release and rotate to allow subtle adjustments to the tonal balance of the sound

10. Direct - This control gives the audio signal a more direct path to the power amplifier stage of your amplifier, bypassing the tone control circuits for the purest possible sound quality

11. Volume - Use to increase/decrease the level of the sound from the outputs of the amplifier. This control affects the level of the loudspeaker output, the pre-amp output and the headphone output. It does not affect the Tape Out connections.

Remote Control Features:

  • Standby/On - Switches the 851A (and 851C) between On and Standby  mode.
  • Volume Up/Down - Volume adjustment
  • Source - Press to cycle through the 851A inputs.

3.AC power socket - Once you have completed all connections to the amplifier, plug the AC power cable into an appropriate mains socket then switch on. Your amplifier is now ready for use

4.Loudspeaker terminals - Two sets of loudspeaker terminals are available, A (main loudspeaker terminals) and B (secondary loudspeaker terminals). Both sets of speakers can be turned on and off independently. Connect the wires from your left channel loudspeaker to the Left + & - terminals, and the wires from the right channel loudspeaker to the Right + & - terminals. In each case, the red terminal is the positive output and the black terminal is the negative output

5.IR (Infrared) Emitter In - Allows modulated IR commands from multi-room systems to be received by the amplifier. Commands received here are not looped out of the Control Bus

6.RS232C - The RS232C port allows external serial control of the 851A for custom install use.  This port can also be used by Cambridge Audio service personnel for software updates

7.Control Bus

  • In - Allows un-modulated commands from multi-rooms systems or other components to be received by the unit.
  • Out - Loop out for control bus commands to another unit. Also allows the 851A to control some Cambridge Audio units.

8.Preamp Out - Connect these sockets to the inputs on an external power amplifier(s) or active subwoofers etc.

9.Rec In - Connect to a tape deck or to the analogue output sockets on a MiniDisc, portable digital music player or CD recorder using an interconnect cable from the recorder’s Line Out sockets to the amplifier’s Rec In sockets

  • Rec Out- For connection to the line level inputs of Tape Recorders or other analogue recording apparatus

10.Source 1 & 2 Audio inputs - These inputs feature either unbalanced (phono/RCA) or balanced (XLR) connections. The balanced connection is the higher quality option and can reject noise and interference in the cable when used with other equipment that supports this function. An XLR connector is wired Pin 1 - Ground; Pin 2 - Hot (inphase); Pin 3 - Cold (phase-inverted)

11.Sources 3-7 - These inputs are suitable for any ‘line level’ source equipment such as CD players, DAB or FM/AM tuners etc
