Connections

The 651W features both balanced (XLR) and unbalanced (RCA/Phono) output connections. For the best quality we recommend you use a balanced output
with pre-amplifiers that feature this connection (such as our own Stream Magic 6).
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).
