level of the Principal Grand relative to the main
loudspeakers regard-less of whether the High-Level or
the Line-Level inputs are used.

stronger or louder position, it may be necessary to
lower the overall volume of the Principal Grand.

Principal Grand in an always On- position while the
Auto-Position automati-cally places the Principal Grand
into standby when there is no signal for 15 minutes.
