Setting Up
Mains Power Connections
Mains power is applied via a fused IEC inlet. The unit must be earthed. The voltage selector
switch is used to match the unit to the mains voltage in your territory. The mains fuse must be
the correct value for the voltage selected, 115V requires a T3.15A fuse while 230V requires a
T1.6A fuse. The ‘T’ signifies a slow blow type fuse.
You must ensure that the correct voltage and fuse have been selected before
switching the unit on.
Audio Connections
Audio input is via a female XLR connector. The input is electronically balanced with +ve on
pin 2, -ve on pin 3 and ground on pin 1. If your signal source is unbalanced it is usual to
connect the unused signal pin (i.e. Pin 3) to ground. This is normally done inside the
connecting cable. For best results use only good quality screened cables and connectors.

Positioning
The BM6A is designed primarily as a ‘nearfield’ monitor and would normally be positioned
1-3m from the listener. They can be mounted on stands or on the meter bridge of the console
(providing this is substantial enough). For best results the speakers should be ‘aimed’ at the
listener in both vertical and horizontal planes.
In any situation ensure that there is adequate space for ventilation around the heatsink.
