CPhantom Power indicators (MIC +48V) — These green LED indicators light solid when +48 V phantom power is placed on the corresponding mic/line input. Phantom power is not adjustable.

ATTENTION:

•Condenser microphones require phantom power. Dynamic microphones do not require power.

•Never set an unbalanced dynamic microphone to +48V. Doing so can damage the microphone. For condenser mics, verify the mic will safely operate at +48 VDC.

•When a line level source is connected, be certain the +48V phantom power is off (unchecked).

GLAN — The LAN connector has a green LED that lights solid to indicate proper connection to an active LAN and a yellow LED that blinks to indicate data activity.

HReset — The reset actuator initiates system resets (see Reset Actuator and LED Indicator on page 12).

IPower/Reset LED — The green LED indicator adjacent to the reset button duplicates the front panel LED operation (see Reset Actuator and LED Indicator on page 12).

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 and rear power indicator LEDs flash 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 HTML Operation on page 120), using the Firmware Loader in the DSP Configurator program (see DMP Software on page 14), or using

the Extron standalone Firmware Loader software application available on the included disc or at www.extron.com.
