Operation

Controls
Level switch.	This sets the input sensitivity of the unit. The +4 position is intended for
	professional use and means that full power is reached with an input level of
	+4dBm (balanced). The -10 position is intended for semi-professional or
	domestic use and means that full power is reached with an input level of
	-10dBm (unbalanced).
HF Trim	This control allows the high frequency level to be adjusted. The HF Trim
	circuit is a low-Q equaliser which reaches a maximum range of 6dB @ 15kHz
	(see graph).
LF Trim.	This control allows the low frequency level to be adjusted. The LF Trim circuit
	is a low-Q equaliser which reaches a maximum range of 6dB @ 50Hz (see
	graph).

The trim controls are intended to allow the user to make some adjustment of the speaker response to accommodate personal tastes and variations in acoustic environment.

Indicators

There are two LED indicators on the front baffle of the BM15A.

The right hand one is the power/fault indicator. On switching the unit on this will shine red for about five seconds and then turn green to indicate normal operation. If for any reason the amplifier protection circuitry is engaged the LED will turn back to red.
