DIGIDESIGN
PRE
Remote Controllable, World-Class 8-Channel Mic Preamp
PRE is an eight channel, remote
controllable microphone preamplifier
designed to complement the 192 kHz
capabilities and world-class
converters available to Pro Tools|HD
systems. Featuring 8 discrete,
matched-transistor, hybrid mic-
preamp
circuits, PRE can accept nearly
any input signal, easily accommodating
mic, line, and direct instrument (DI)
level inputs on all eight channels. PRE’s
MIDI In, Out and Thru ports allow you
to control PRE’s front panel functions remotely via the Pro Tools software interface or Digidesign control surfaces. This
allows you to place PRE anywhere in your studio (closer to the mic source) as well as instantly recall settings with your
session. All of PRE’s function are also available in stand-alone mode, making the same high-end sonic quality available for
non-Pro Tools applications and all standard MIDI controllers.

FEATURES
Inputs and Outputs
◆ Eight high-performance,discrete matched
transistor hybrid microphone pre-amplifi-
cation circuits can accommodate nearly
any input source.
◆ Each channel features support for XLR mic
as well as 1/4˝ direct instrument (DI) and
line level inputs on the rear panel.Two of
the 1/4˝ line/inst inputs are also duplicated
on the front panel for easy access.
◆ Input gain for each channel is variable
from 0 dB to +69 dB, in approx. 3 dB steps.
◆ Switchable 75 Hz @ 18 dB/octave high pass
filter, phase (polarity) reverse,48 V (phan-
tom power) and an 18 dB pad for each
channel.
◆ Selectable impedance matching for opti-
mizing mic, line or instrument inputs
◆ Separate 1/4˝ send and return insert points
are provided for each inputs allowing you
to access your favorite outboard processor.
◆ All eight channels are output via DB25
connector. This allows easy, uncluttered
interfacing between PRE and your Pro
To ols interface or other mixer/recorder.

Remote Control
◆ MIDI In/Out/Thru ports accommodate
remote operation via Pro Tools software
and Digidesign control surfaces.
◆ Remote control via Pro Tools allows you to
instantly recall all settings on a session by
session basis and create mix templates with
all routing and control.
◆ Remote operation also allows you to keep
PRE near the audio source and away from
the computer environment.
Additional Features
◆ A built in oscillator, with a 1/4˝ output
connector offers a convenient way of cali-
brating to other peripherals, such as the 96
I/O and 192 I/O audio interfaces.
◆ All features are also supported in stand-
alone mode, including remote control via
MIDI, making PRE an ideal analog front
end for any recording system.
◆ Up to nine PREs are supported through
software for up to 72 channels of remote-
controlled Mic Preamp channels.
