Standby mode is a low power mode where the power consumption is less than 10 Watts. The unit should be left in Standby mode when not in use.
azur 840W The 840W features both balanced (XLR) and unbalanced (RCA/Phono) output connections. For the best quality we recommend you use the balanced output with pre-amplifiers that feature this connection (such as our own 840E Pre-Amplifier). Before making any connections to loudspeakers, make sure all power is turned off and only use suitable interconnects (e.g. banana plugs). Ensure that the positive (+) and negative (-) connections are matched.
Power syncing (On/Standby control) 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).
azur 840W The 840W features Mono and Bi-Amped Mono settings that allow two (or more) 840Ws to be used as mono-blocs for high end systems. Below is an example using two 840Ws in Bi-Amped Mono with an 840E. Important 840W settings Only use the Left Inputs on the 840W for Bi-Amped operation. In this configuration the Stereo/Mono switch on the 840W must be set to ‘Mono’ and the Mono mode switch must be set to ‘Bi-Amp’. In Bi-Amped Mono mode each 840W drives one speaker.
Custom installation (C.I.) use Technical specifications Control Bus The 840W features a Control Bus input/output IR Emitter In In Out that allow un-modulated remote control commands (positive logic, TTL level) to be received electrically by the unit and looped to another unit if desired. These control commands are typically generated by custom installation (multi-room) systems or remote IR receiver systems. The Control Bus sockets are colour-coded orange.
