azur 840W

Connections

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. Your loudspeaker may have more than one pair of connecting terminals; LF (Low Frequency) and HF (High Frequency). For single-wiring it is recommended to connect to the LF terminals. The metal strip connecting the low-frequency terminals to the high-frequency terminals must not be removed (only to be removed for a bi-wiring system).

ENGLISH

Unbalanced stereo connections

The diagram below shows the 840W connected to an 840E using the Unbalanced Audio inputs via phono/RCA connectors, single wired to a pair of loudspeakers.

When using unbalanced (phono/RCA) connections, the Left and Right Input Type switches on the 840W must be in the ‘Unbalanced’ position.

Note: In this configuration the 840W must be set to Stereo mode.
