Analog Inputs

The Digital Recording Console 02R is equipped with 24 individual analog
input connectors. The first sixteen channels, 1 through 16, are monophonic
input channels designed for microphone to line level signal inputs. The last
eight channels, 17 through 24, are stereo pairs designed for line level
signals only.
In addition, the first eight channels not only have selectable input
connectors, XLR-type or phone, but they also have an insert connector,
allowing you to patch external signal processors before the input signal is
converted to digital.
For monitoring the output of a stereo tape recorder or another similar
analog device, the 02R also has two pairs of 2TR IN phone connectors.

Phantom Power

Phantom power provides a +48 VDC power source for condenser type
microphones. It is applied to the XLR-type connectors (INPUT A) for input
channels 1 through 8. The phantom power switch for each channel is used
to turn it ON and OFF. Phantom power is applied to each individual input.
Phantom power can only be applied to the XLR-type connectors
(INPUT A) for input channels 1 through 8. Select those connectors with the
A/B switch: up for A, down for B.
With phantom power set to ON, non-phantom powered microphones,
dynamic microphones, and balanced line-level sources can still be
connected to INPUT A connectors for input channels 1 through 8.
However, be careful with unbalanced sources.
