Mode 5 — Factory default reset: With power on, press and hold the reset button
until the reset LED blinks 3 times (~9 seconds). Release then momentarily (<1 second)
press the reset button to return the DMP128 to factory default conditions. If the second
momentary press does not occur within one (1) second, the reset is exited.
The default (reset) state of the device is:
• All mix-points are set to 0dB gain and muted
• Input 1 is routed to Output 1
• Input 2 is routed to Output 2
• Input 3 is routed to Output 3
• Input 4 is routed to Output 4
• Input 5 is routed to Output 5
• Input 6 is routed to Output 6
• Input 7 is routed to Output 7
• Input 8 is routed to Output 8
• All outputs active (unmuted, 100% volume).
• No inserted or active DSP processing.
• All audio inputs are set to 0dB gain and muted.
• All preset and group master memory is clear (empty).
Digital I/O Ports
The four 6-pole 3.5 mm captive screw connector Digital I/O ports provide twenty
configurable digital input or output ports designed to connect to various devices such
as motion detectors, alarms, lights, LEDs, buttons, photo (light) sensors, temperature
sensors, relays (requiring ≥30 mA), and others.
All ports are tied to a common ground (one common ground for each 6-pole connector),
but can be individually configured to operate in one of two modes: digital input or digital
output.
The ports are configured using DSPConfigurator. Each port can be configured to monitor
or drive TTL level digital signals (see DigitalI/OPorts on page88).
