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.

Here you can adjust the listening settings of the amplifier to personal preference. The menu system is easy to navigate and control, simply by using the input select buttons to turn a feature on (solid circle) or off (no circle) and the volume control knob to increase/decrease settings. Balance Mode Volume Volume Mode Press the Mode button to enter Balance mode. BALANCE will appear on the display and can be adjusted using the volume control. Press the Mode button again to return to Volume mode or wait 5 seconds for the 840A to automatically exit Balance mode. Bass and Treble Volume Bass Treble Direct Adjust the volume control knob on the front panel (or using the remote control). `OdB' indicates maximum volume while lower volume settings progress into the negative range. This can also be changed to volume units (0-72) in the System Configure menu. Speaker A/B Speaker A/B These controls allow subtle adjustments to the tonal balance of the sound. Press to release and rotate to adjust (press back in when desired settings found). These controls only modify the sound through your loudspeakers and the Pre-Out sockets; they do not affect the signals sent through the Tape Out connections. With a well produced CD and a good system the tone controls are unnecessary and can be switched out by the Direct switch. [. . . ] Ensure that your tape deck/turntable is not too close to the amplifier. There is no sound Make sure the unit is not in Standby mode. Check that 'TAPE MON' is not switched on (unless tape input is required). Make sure unit is not in mute mode. Unable to make or play tape recordings Check that TAPE MON and TAPE OUT have been connected correctly. There is weak bass or diffused stereo imaging Ensure that speakers are not wired out of phase. Message on display flashing See section on CAP5 protection system. There is no sound on one channel Ensure that balance control is in the correct position. Check interconnects. 22 Azur Class XD integrated amplifier 840A Class XD integrated amplifier TECHNICAL SPECIFICATIONS 840A Power Output THD (unweighted) 120W RMS into 8 Ohms 200W RMS into 4 Ohms < 0. 0015% 1 kHz at 80% of rated power < 0. 015% 20 Hz - 20 kHz at 80% of rated power Frequency Response S/N ratio (ref 1W/8 Ohm) Input impedances 10 Hz - 50 kHz +/- 1 dB > 83 dB Input 1 (balanced) 10 kOhm Inputs 2-7 68 kOhm Tape Input 68 kOhm > 110 at 1 kHz 800W This guide is designed to make installing and using this product as easy as possible.
