Front Panel Operation
NOTE:
For operation details for all models, see the MLS 608 D Series User Guide, available at
www.extron.com
.
a
Power/reset status LED — This LED lights green when power is applied, and amber when in standby mode. It also indicates
the reset mode when the reset button is being operated (see below).
b
Reset button — In order to reset the MLS switcher to one of two available reset modes via the front panel, press and hold
this recessed button in and observe the LED for confirmation of unit resetting.
Reset Mode 1, Use factory firmware — To reset temporarily to the factory default firmware, press and hold the reset
button in while applying power to the unit.
NOTES:
• After a Mode 1 reset, update the firmware to the latest version. DO NOT use the factory firmware resulting
from the reset. Factory firmware must be re-uploaded if that is the version to be used.
• If you do not want to update the firmware, recycling the power reinstates the firmware version used before
the Mode 1 reset.
Reset Mode 5, Reset to factory default — To reset the device to factory defaults (with the exception of the firmware),
press and hold in the reset button for approximately 9 seconds, until the LED blinks three times (once at 3 seconds,
6 seconds, and 9 seconds), and then release.
Within 1 second press and release the reset button once (<1 second). Nothing will happen if the momentary press
is not made within 1 second.
c
Front panel mini USB configuration port — Connect a computer to this port, using a mini USB cable (not supplied), for
configuration, control, and firmware upgrades.
NOTE:
For details of device configuration via software, SIS commands, and firmware updating for all models, see the
DSP Configurator Help file or the MLS 608 D Series User Guide, both available at
www.extron.com
.
d
Source selection buttons — Use these buttons to select or switch between inputs. The button lights amber to indicate which
input is active.
e
Program volume adjustment knob — Use this to set or adjust the program output
volume (attenuation, from -100 dB to 0 dB) as desired. The LEDs indicate the volume
level (all off at -100 dB, all on at -4 to 0 dB). Rotate the knob clockwise to increase
volume, counter-clockwise to decrease volume. See table at right for LED/dB values.
f
Mic volume adjustment knob — Use this knob to set or adjust the volumes of the two
mic inputs (see page 1,
j
) as desired. The LEDs indicate the volume level.
Rotate the knob clockwise to increase volume, counterclockwise to decrease volume.
NOTE:
The system and microphone volume settings and adjustments
can be made using Extron DSP Configurator program or via SIS
commands. See the MLS 608 D User Guide for details
