5.2 Microphone/line controls
Use the volume controls (9) to individually control the
sound level of microphone/line inputs 1 through 6.
5.3 Music controls
5.3.1 Source selection
Use the music source selector (11) to select one of the
connected music sources.
5.3.2 Volume control
Use the music source volume control (12) to control the
sound level of the selected music source.
5.4 Tone control
5.4.1 Introduction
The unique tone controls provide separate control for
mic/line inputs and music inputs so that the voice on
the microphones can be specifically optimized for
excellent speech or singing. Correspondingly, the tone
controls for background music provide the most
appropriate music reproduction.
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.
5.4.2 Microphone/line tone control
The tone control for the microphone and line inputs
boosts warmth in voices without boosting rumble, and
cuts rumble without loosing warmth in the low
frequencies. In the high frequencies, the tone control
boosts sparkle without adding sharpness, but when
cutting is first, cuts harshness and sharpness without
reducing clarity.
Use the Hi (high) and Lo (low) tone controls (see
figure 5.2, numbers 3 and 10) to collectively change the
tone of microphone/line inputs 1 through 6.
5.4.3 Music tone control
The tone control for the music inputs boosts deep bass
first without making the sound boomy, and cuts rumble
without loosing warmth in the low frequencies. In the
high frequencies, the tone control is similar to the
microphone inputs, with slightly different frequencies to
suit music reproduction.
Use the Hi (high) and Lo (low) tone controls (see
figure 5.2, numbers 5 and 13) to change the tone of the
selected music source.
Note
Users can create custom labels for the:
microphone/line inputs, description of the music
sources, and audio output zones 1 and 2. These
labels can be attached to the mixer amplifier at
position numbers 2, 4, and 6 (see figure 5.2).
Colored pins can also be inserted at various
positions around the dial controls to indicate the
favorite settings for a particular application.
