Power Cycle

Current mixing and audio processor settings, the current state of the device, are saved in
nonvolatile memory. When the unit is powered off, all settings are retained. When the
unit is powered back on, it recalls settings from the nonvolatile memory. If a configuration
was in process during the power down, these saved mix, audio level, and audio DSP
processor settings become active.
On power up the unit performs a self-test. The front power indicator LED flashes during
the test, then light solid when the unit is available for operation or programming.

Firmware Updates

The firmware of the DMP 64 can be updated through Ethernet, USB, or RS-232
connection. The user can obtain new firmware from the Extron website, or from an Extron
Applications Engineer via e-mail. After obtaining the new firmware, upload it to the unit
via the served web pages, (see

Phantom Power indicators (MIC +48V) — These green LED indicators light when
+48 V phantom power is placed on the corresponding mic/line input. Phantom power
is not adjustable.
NOTE: Condenser microphones require phantom power. Dynamic microphones
do not require power.
When a line level source is connected, be certain the +48V phantom
power is off (unchecked).
CAUTION: Never set an unbalanced dynamic microphone to +48V. Doing so
may damage the microphone. For condenser mics, verify the mic
will safely operate at +48 VDC.
LAN — The LAN connector has a green LED to indicate proper connection to an active
LAN and a yellow LED that blinks to indicate data activity.
Reset — The reset actuator initiates system resets. See
later in this chapter for additional information.
Power/Reset LED — The green LED indicator adjacent to the reset button duplicates
the front panel LED operation. See
additional information.
