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

Use the music source selector (8) to select one of the 
connected music sources.

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

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.
