5.2 Microphone/line controls
Use the volume controls (7) to individually control the
sound level of microphone/line inputs 1 through 4.
5.3 Music controls
5.3.1 Source selection
Use the music source selector (8) to select one of the
connected music sources.
5.3.2 Volume control
Use the music source volume control (9) to control the
sound level of the selected music source.
5.4 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, but also have a
powerful contour that addresses problems found in real
situations.
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 5.1, numbers 4 and 10) to change the tone.
5.5 Output controls
5.5.1 Master volume control
Use the master volume control dial (5) to collectively
control the sound level of all outputs, except the
emergency announcement/signal.
Note
Users can create custom labels for the
microphone/line inputs and description of the
music sources. These labels can be attached to
the mixer amplifier at position numbers 2 and 3
(see figure 5.1). Colored pins can also be
inserted at various positions around the dial
controls to indicate the favorite settings for a
particular application.
