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 DMP128 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 0dB 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 0dB 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 DSPConfigurator. Each port can be configured to monitor
or drive TTL level digital signals (see DigitalI/OPorts on page88).
