Power LED
— The Power LED lights to indicate power is on. If
AC voltage is available, power is on. When power is first
applied, all front panel LEDs flash to indicate that the power up
sequence was accomplished satisfactorily.
2
Outputs button and LED —
The Outputs button toggles
between output 1 and output 2. The Outputs LED indicates the
selected output.
3
Input buttons and LEDs —
The input 1 through input 6 buttons
select an input for output. The input 1 through input 6 LEDs
indicate the selected input.
As a secondary function, the input 5/
and input 6/
buttons
increase and decrease the amount of audio gain for a selected
input and the input 1 through 5 LEDs indicate the audio level of
the selected input. See
Audio gain and attenuation
in this chapter.

I/O configuration/save button and LED
— The I/O Conf/Save
button has two functions, selecting between video and audio
and selection of audio gain and attenuation mode. The I/O
LED identifies which function is selected.
Video and/or audio selection
— When pressed and
released
,
the I/O button cycles through video and audio, audio only, and
video only selected for configuration (figure 3-2). The I/O LED
is off when this function is enabled, and the Video/+dB and
Audio/-dB LEDs (5) report the video and audio input selection.
Audio gain and attenuation mode
— When pressed and
held
,
the I/O button selects or deselects audio gain and attenuation
mode, in which the operator can adjust the audio gain and
attenuation. The I/O LED blinks when this function is enabled,
and the Video/+dB and Audio/-dB LEDs are part of the audio
level display for the selected input. See
Audio gain and
attenuation
in this chapter.

Video/+dB and Audio/-dB LEDs
— The function of the Video/
+dB and Audio/-dB LEDs varies depending on whether the
I/O Conf/Save button is selecting between video and audio or
if the switcher is in audio gain and adjustment mode.
Video and/or audio selection
— The Video/+dB and Audio/
-dB LEDs indicate whether video, audio, or both are selected for
display and/or selection. If audio is broken away and video
and audio are selected for display, the Audio/-dB LED blinks.
Audio gain and attenuation mode
— The Video/+dB and
Audio/-dB LEDs indicate the polarity of the audio level setting.
See
Audio gain and attenuation
in this chapter.
Front Panel Operations
Plug in all system components and turn on the input devices
(such as DVD players, laserdisc players, VCRs, and DSS
receivers) and the output devices. Set the input devices to
output video using each device’s own operating instructions.
Creating ties
A
Tie
is an input-to-output connection. An input can be
tied
to
both outputs. (An output can never be
tied
to more than one
input.)
Create video and/or audio ties using the front panel buttons as
follows:
You cannot create a tie from the front panel if the
MAV 62 is in audio gain and attenuation mode (if the
I/O LED is blinking). If the I/O LED is blinking, press
and
hold
the I/O Conf/Save button until the I/O LED
goes out.
