[. . . ] Pre-Amplifier User's manual 2 azur 840E Your music + our passion ENGLISH Important safety instructions For your own safety please read the following important safety instructions carefully before attempting to connect this unit to the mains power supply. They will also enable you to get the best performance and prolong the life of the unit: 1. Install in accordance with the manufacturer's instructions. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. [. . . ] Any noise voltages that appear identically on both lines (these are called common-mode signals) are cancelled by the subtraction. Make sure the Balanced/Unbalanced switch for Inputs 1 and 2 are set to the connection type you wish to use.

For this feature to work the units must be connected together by RCA/phono leads. Connect the Control Bus Out from the 840E to the Control Bus In on the 840W. Continue the chain to other Azur models if it is required to sync more units (refer to the 840E's own manual for more information as this requires some setup). Note: The 840E features a Trigger Out which can alternatively be used to control the 840W's Standby/On status if desired. Again, the procedure is simply to connect the two units together (using a 3. 5mm to 3. 5mm mono mini-jack lead in this case). Control Bus is the recommended method when using an 840E and other Cambridge Audio equipment with Control Bus In/Out. Trigger In/Out can be useful if the 840W (and indeed 840E) is desired to be controlled by other equipment that features trigger outputs (Custom install and/or Multi-Room Systems etc). 840W Loudspeaker Terminals - Right Impedance 4 - 8 ohms Please ensure that loudspeaker terminals are fully tightened Veuillez s'assurer que les bornes de l'enceinte sont entièrement serrées IMPORTANT!Refer to Manual for more information.

The Control Bus sockets are colour-coded orange. 840E ENGLISH Troubleshooting There is no power Ensure the AC power cord is connected securely. Ensure the plug is fully inserted into the wall socket and is switched on. Check fuse in the mains plug or adaptor. An IR Emitter Input is also provided that allows modulated IR remote control commands to be received electrically by the unit. [. . . ]
