Volume control
Use the music source volume control (8) to control the sound level of the selected music

Tone control
The tone controls are not standard bass and treble controls: they can be used as a traditional
tone control with high and low control.
The tone control for the low frequencies boosts deep bass first without making the sound
boomy, and cuts rumble without loosing warmth in the low frequencies.
Use the Hi (high) and Lo (low) tone controls (see
Figure 8.1
, numbers 3 and 7) to change the
tone.

Master volume control
Use the master volume control dial (4) to collectively control the sound level of all outputs,
except the emergency announcement/signal.
CAUTION!
Before applying power, always check the voltage indicator plate at the rear of the unit.
