5.2Microphone/line controls
Use the volume controls (9) to individually control the sound level of microphone/line inputs 1 through 6.
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 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.
5.3Music controls
5.3.1Source selection
Use the music source selector (11) to select one of the connected music sources.
5.3.2Volume control
Use the music source volume control (12) to control the sound level of the selected music source.
5.4Tone control
5.4.1Introduction
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.
5.4.2Microphone/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 desired, 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.
5.4.3Music 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.
