Balanced connections in an audio system are designed to reject electrical noise, from power wiring etc, and also the effects of noise currents flowing through ground connections. The basic principle of balanced interconnection is to get the signal you want by subtraction, using a three-wire connection. One signal wire (the hot or in-phase) carries the normal signal, while other (the cold or phase-inverted) carries an inverted version. The balanced input senses the difference between the two lines to give the wanted signal. Any noise voltages that appear identically on both lines (these are called common-mode signals) are cancelled by the subtraction. An additional advantage is that the connection effectively carries twice the signal level and so improves the signal-to-noise ratio. The 840A and 840C are designed to work at their highest performance when a balanced interconnect is used; high quality stereo XLR to XLR interconnects should be used. 840A Power On Off Multi-Room Input 1 Balanced Audio Right Right Input 1 Left Left Left Input 2 Input 3 Input 3 Input 2 IR3 GND RS232C www. cambridge-audio. com Power Rating: 230V AC ~ 50Hz Max Power Consumption: 800W Manufactured in an ISO9002 approved facility Right _ A Power AC Loudspeaker Terminals Impedance 4 - 8 ohms Right _ N2409 B _ 840C Power On Off azur 840C Upsampling Compact Disc Player Max Power Consumption: 40W Caution Risk of electric shock.
