| Second generation proprietary Class XD technology |
| 120W per channel into 8 Ohms or 200W per channel into 4 Ohms |
| Oversized low flux toroidal transformers |
| Completely separate pre-amp and power amp toroidal transformers and circuits make the 840A effectively a pre and power amplifier combination in one chassis |
| Sophisticated resistor ladder and relay based attenuator for extremely accurate volume/balance control |
| Two pairs of very high current output transistors per channel in revised configuration for improved integration with Class XD |
| Twin rectifiers and separate transformer taps for dual mono operation of the left and right power amplifiers |
| RS232 port, IR emitter In and Control Bus In/Out for seamless integration with custom install systems |
| A-BUS™ / Incognito™ Ready connections compatible with Cambridge Audio’s new Incognito multi-room keypads or other A-BUS compatible keypads allow the 840A to form the hub of a simple but highly effective 3 zone multi-room system |
| Fixed level inputs allow the 840A to provide the front channel amplification when integrated with home cinema systems that use an AV processor |
| Cambridge Audio proprietary CAP5™ protection system |
| 8 inputs one with balanced XLR connections in addition to single ended phono/RCA |
| Nameable inputs |
| Backlit LCD screen |
| Extruded aluminium side panels and solid aluminium front panel plus an ultra rigid, acoustically dampened chassis |
| Navigator style Azur remote which also controls o iPod™ track skip and volume functions o Azur CD players o Cambridge Audio’s Incognito keypads o Discrete commands for custom install use |
| Available in silver or black |
