8.2	Microphone/line controls
	Use the volume controls (9) to individually control the sound level of microphone/line inputs 1
	through 4.
8.3	Music controls
8.3.1	Volume control
	Use the music source volume control (8) to control the sound level of the selected music
	source.
8.3.2	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.
8.4	Output controls
8.4.1	Master volume control
	Use the master volume control dial (4) to collectively control the sound level of all outputs,
	except the emergency announcement/signal.
