Usb Configuration Port (Front Panel); Front Panel Indicators - Extron electronics DMP 128 User Manual

usB configuration Port (Front Panel)

A front panel configuration port uses an Extron USB A Male to USB Mini B Male
Configuration Cable, 26-654-06 for connection to a PC computer USB port.
The USB 2.0 port uses a mini type-B connector to connect to a host computer for
control. The DMP 128 USB driver must be installed prior to using the port (see

Input Indicators — Stacked red (signal clipping) and green (signal present) LEDs for
inputs 1 through 12 . Each stack represents one input channel.
The green signal LED varies in brightness corresponding to the real-time input or
output signal level (see item d , below). It begins to light at – 60 dBFS increasing
in steps to full intensity as the signal level increases. When the signal level reaches
– 3 dBFS or above, the red clipping LED lights and remains lit as long as the signal
remains above – 3 dBFS. When it falls below that level, the red LED remains lit for 200
milliseconds, after which the display resumes real-time monitoring of the signal level.
Output Indicators — Stacked red (signal clipping) and green (signal present) LEDs
for outputs 1 through 8. Each LED stack represents one output channel.
