MPS 409 Setup Guide (Continued)
In separate-combine mode, only one input selection is allowed from the
HDMI/DVI groups along with a single input selection from the VGA/YUV group
and another from the Video group. So there will only be three front panel input
LEDs lit in combined mode rather than four when in separate switcher mode.
To enable combined switcher mode:
Press and hold the Mode button (VGA/YUV Input #1) for three seconds, then
press and release the Combine DVI/HDMI button (DVI input #2). The Combine
DVI/HDMI button LED indicates if combined switcher mode is on (when lit)
or off. The Single and Separate button LEDs indicates whether it is in single
switcher mode or separate switcher mode. When the Mode button is released,
the LED resumes input indication.

Setup and Operation — Optimizing the Audio
For optimal audio quality, the audio input levels can be adjusted individually. In addition, the microphone
and program output levels can be adjusted separately using the front panel controls. Program output and
microphone levels are independent from each other. Muting program audio does not mute the microphone
input.
Setting the Input Audio Level
1. Simultaneously press and hold the Program Audio Mute and MIC Mute
buttons until the two mute LEDs flash three times, then release both
buttons.
2. Press a Video Input button for the audio to be adjusted (video input #1
is shown). If an input button is not pressed, the switcher times out and
exits audio level adjustment mode.
3. In audio adjustment mode, when an input button is pressed, the front
panel input LEDs indicate the current gain/attenuation setting. Factory
default is 0 dB (all LEDs off). Rotate the Program Audio volume knob
clockwise to increase and counterclockwise to decrease the audio level. The
front panel LEDs display the level setting as the knob is adjusted (see
Audio Gain/Attenuation Adjustments in the MPS 409 User Guide).
4. Once the desired level is achieved, to adjust another input, select it within
three seconds. If audio adjustments are complete, to exit the gain/attenuation
mode:
a. Do not press any front panel buttons for at least three seconds, or
b. Press the Program Audio Mute and MIC Mute buttons.
At any time during the adjustments, if the front panel buttons are not pressed or
the program knob is not rotated within three seconds, the switcher times out and
the gain/attenuation mode is exited.
Setting the Program Output Audio Level
1. Turn on all equipment and select an input with an audio signal present.
2. Turn on program audio by pressing the Program Audio Mute button (the LED
goes out).
3. Using the Program Audio volume control (right), adjust the volume of the
audio amplifier connected to the Program Audio Out connector to achieve
the desired sound level.
Setting the Microphone Level
1. Turn on all equipment and select an input with an audio signal present.
2. If the program audio output level has not been adjusted, do so before setting
the microphone level.
3. If phantom power is required for the microphone, be certain it is on.
4. Turn on the microphone by pressing the MIC Mute button (the LED goes out).
5. Talk into the microphone in a normal voice and adjust the Mic volume knob
(right) to the desired sound level.
