accept balanced or unbalanced mono mic or line level signals and provide phantom
power. Mic/line inputs provide gain settings to accommodate consumer (– 10 dBV)
and professional (+ 4 dBu) operating line level sources, plus mic level sources. Up to
eight mono mics or line inputs, balanced or unbalanced in any combination can be
connected to these inputs, (see figure 2).

ATTENTION:
• For unbalanced audio, connect the sleeves to the ground contact. DO NOT
connect the sleeves to the negative (–) contacts.
• Pour l'audio asymétrique, connectez les manchons au contact au sol. Ne PAS
connecter les manchons aux contacts négatifs (–).

captive screw connectors each provide five
configurable digital input or output ports allowing
connection of up to twenty various devices such
as motion detectors, alarms, lights, LEDs, buttons,
photo (light) sensors, temperature sensors, and other
devices.
Digital I/O ports monitor or drive TTL level digital signals. The inputs can be configured
to operate in one of two modes: digital input or digital output. In output mode, the
device can source up to 250 mA at +5 V. In Input mode, voltages greater than 1 V
indicate a logic 'high' signal while voltages less than 1 V indicate a logic 'low'.
All digital I/O 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
NOTE: These ports can be configured via the DSP Configurator (see
Digital I/O Ports on page 89).
