PCI card has a connector to link to the Digi 001 interface and also has a pair of ADAT
optical connectors for multichannel digital input and output (I/O). Each optical connector
can either carry eight channels of 24-bit digital audio or be switched using the software
for use as an additional two-channel S/PDIF interface.
The I/O interface provides eight analog audio inputs and outputs with 24-bit converters,
S/PDIF digital audio input and output, a stereo headphone jack socket, a footswitch jack
socket, and a pair of MIDI In and Out sockets. The total number of audio inputs and
outputs is 18—counting the eight ADAT digital channels, the two S/PDIF digital
channels, and the eight analog channels.
The MIDI In and Out connectors let you use the Digi 001 as a basic 16-channel MIDI
interface for Mac or PC. The headphone jack socket lets you connect a pair of stereo
headphones to monitor whatever audio you have routed to analog outputs 1 and 2 using
the PT LE software. The footswitch jack lets you connect a footswitch to control the
QuickPunch and MIDI punch-in and punch-out recording features.
The 001’s microphone preamps will accept a wide range of microphone types, including
high-quality “condenser” models that require “phantom” power. Dynamic microphones
(such as the popular Shure SM58) don’t need power, but professional studio models
(such as the AKG C414) need 48 V that the preamplifier can send through the
microphone cables into the microphone, rather than through separate power cables—
hence the name “phantom” power.
