User manual CAMBRIDGE AUDIO AZUR 840W

[. . . ] azur 840W ENGLISH Class XD power amplifier User's manual 2 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 from and prolong the life of the unit: 1. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. [. . . ] Please ensure that the loudspeaker terminals have been tightened completely to provide a good electrical connection. It is also possible for the sound quality to be affected if the screw terminals are loose. When Mono mode has been selected, switches the 840W between BiAmped Mono and Bridged Mono. 7 Control Bus In - Allows un-modulated commands from multi-room systems or other components to be received by the unit. The 840W can also be switched between On and Standby mode by connecting the Control Bus output of an 840E pre-amplifier to the Control Bus input of the 840W. Refer to the `Power syncing' section of this manual for more information. 8 Audio input types The 840W features either unbalanced (phono/RCA) or balanced (XLR) input 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 (in-phase); Pin 3 - Cold (phase-inverted). Use the Left and Right Input Type switch (Item 4) to select the connection type you wish to use. When using either the balanced or unbalanced input, make sure that no cables or equipment are connected to the unused input, as this may degrade operation. The unused input does not need to be terminated and this should not be done. 2 Trigger In, Out/Thru For Custom Install use, the 840W can be turned on and off (i. e. brought in and out of Standby mode) by the presence of 5-12V DC at the Trigger input. A trigger input will also produce an internally generated 12V DC trigger output at the Output/Thru connection. Turning the 840W on from the front panel also produces a 12V DC trigger output at the Output/Thru connection. This can be used to turn on/Standby other connected power amplifiers or other equipment if desired. Refer to the `Power syncing' section of this manual for more information. 9 IR (Infra-Red) Emitter In Balanced Audio Allows modulated IR commands from multi-room systems or IR repeater systems to be received by the unit. 10 For connection to the balanced XLR outputs of suitable pre-amplifiers that have this kind of output (such as our own 840E model). The preamplifier used should be capable of providing at least 1V rms of output per phase (i. e. 3 AC power socket Once you have completed all connections to the unit, plug the AC power cable into an appropriate mains socket then switch on. 11 Unbalanced Audio For connection to the normal (single ended) RCA/Phono outputs of a suitable pre-amplifier (such as our own 840E model).
