Output connections - Unbalanced

The 840E features both balanced (XLR) and unbalanced (RCA/Phono) output connections. For the best quality we recommend you use the balanced output with power amplifiers that feature this connection (such as our own 840W Class XD power amplifier).

The diagram below shows the 840E pre-amplifier connected to an Azur 840W power amplifier and 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.

840E

Before making any connections to the 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).

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