7.1. MX-6224D Digital Mixer Amplifier 2x240W
[Front]
1. Power switch
Turns on and off the main power.
2. Sleep indicator
Lights green when the power switch is ON and
the unit is placed in sleep mode.
3. Microphone volume controls
Adjust each microphone input.
4. AUX 1 and 2 volume controls
Adjust the AUX 1 and 2 inputs.
5. Outside zone output switch
Turns on and off the outside zone output.
6. Outside zone output indicator
Lights red when sound is output from the Outside
zone output terminals (34).
7. Room zone output switch
Turns on and off the room zone output.
8. Room zone output indicator
Lights green when sound is output from the Room
zone output terminals (33).
9. Protection indicator
Lights red when the following situations are
detected.
• Built-in digital amplifier failure
• Overcurrent flow inside the unit
• Overheat inside the unit
• Speaker output failure
• Excessive input of low frequency signals
10. Peak level indicator
Lights red when the output sound level reaches
the peak level (0 dB) referenced to 0 dB at rated
output (100 V).
In general use, each volume should be set below
the point where the red indicator (0 dB) begins to
light.
11. Signal level indicator (–20 dB)
Lights green when the power amplifier's output
level is –20 dB referenced to 0 dB at rated output
(100 V).
12. Low frequency control (80 Hz)
Turn the control knob clockwise to enhance low
frequencies and counterclockwise to weaken
them. The frequency is flat at the center position.
Note
This Equalizer control will not affect the AUX 1
and 2 inputs.
13. Middle frequency control (2.5 kHz)
Turn the control knob clockwise to enhance middle
frequencies and counterclockwise to weaken
them. The frequency is flat at the center position.
Note
This Equalizer control will not affect the AUX 1
and 2 inputs.
14. High frequency control (12 kHz)
Turn the control knob clockwise to enhance the
high frequencies and counterclockwise to weaken
them. The frequency is flat at the center position.
Note
This Equalizer control will not affect the AUX 1
and 2 inputs.
15. Effect control
Adjusts effect response.
Turn the control knob clockwise to strengthen the
response of the effect selected by the Effect preset
type selection switch (16), and counterclockwise
to weaken it.
Turning the control fully counterclockwise
provides no effect response.
