1073OPX Introduction 1
The 1073OPX is an eight-channel Microphone, Line, and Instrument preamplifier
featuring Marinair® transformer-coupled microphone preamplifiers. Housed in a
2 unit 19’’ rackmount enclosure with an optional digital interface, the 1073OPX is the
ideal preamp for any studio setup, allowing engineers, producers, and artists to
expand their recording capabilities, and access the legendary Neve sound.
The 1073OPX DI Input is a transformer-less Class-A design offering +30 to +60dB of
gain and accessed through front-mounted XLR/TRS combi inputs for fast, high-quality
instrument recording.
This digitally controlled preamplifier has Total Recall™capability via the proprietary
1073OPX remote control software. Every control and setting can be adjusted
remotely via the Neve® Remote-Control software which can be installed onto any
compatible MAC or PC computer. This software provides a simple and elegant
remote-control system for users of digital audio workstations, production suites, or
live sound reinforcement systems.
Up to eight 1073OPX units can be connected and controlled remotely, giving up to 64
Mic Preamplifiers, Line Level, or DI inputs, all managed from a single computer. The
unit always powers up with all settings, levels and states as they were at power-down.
Two optional Digital Cards provide AD/DA conversion for all eight preamps and digital
monitor returns over three available formats –Dante/USB/ADAT. The USB/DANTE
card allows the 1073OPX to be used as a Dante enabled Audio-over-IP preamplifier
with both Primary and Secondary network capability and the USB port enables the
1073OPX to function as a primary standalone audio interface for any DAW enabled
computer. The USB/ADAT card provides the same USB functionality with added ADAT
connectivity, allowing the 1073OPX to operate as an expansion preamp for ADAT-
enabled audio interfaces.
A unique feature of the 1073OPX is its analogue and digital monitor return path. This
feature allows the device to be used as an analogue monitoring system feeding studio
loudspeakers, cue mix systems as a primary audio interface with complete I/O for any
MAC/PC DAW enabled computer.

Rack Mount Instructions 1
Elevated Operating Ambient- If installed in a closed or multi-unit
rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore,
consideration should be given to installing the equipment in an
environment compatible with the maximum ambient temperature
(30°C) specified by the manufacturer.
Reduced Air Flow - Installation of the equipment in a rack should be
such that the amount of air flow required for safe operation of the
equipment is not compromised.
Mechanical Loading - Mounting of the equipment in the rack should
be such that a hazardous condition is not created by improper or
uneven mechanical loading.
Reliable Earthing - Reliable earthing of rack-mounted equipment
should be maintained. Particular attention should be given to
supply connections other than direct connections to the branch
circuit (e.g. use of power strips).
Installation en Baie (rack) 1
Température en service élevée – si l’installation est effectuée dans
un endroit clos et/ou multi-rack, il se peut que la température
localisée soit plus élevée que la température ambiante. Dans ce cas,
il faudra faire attention à ce que l’environnement soit compatible
avec la température ambiante maximale (30°) spécifiée par le
fabricant.
Aération réduite –l’installation de l’appareil dans une baie devra être
réalisée afin de permettre une circulation d’air suffisante pour que le
fonctionnement de celui-ci ne soit pas compromis.
Installation mécanique – l’installation de l’appareil dans un rack
devra être réalisée afin d'éviter une position qui s'avèrerait
dangereuse dans le cas d'une installation instable.
Mise à la terre convenable – la mise à la terre dans le cas d’une
installation en baie/rack doit être maintenue. Une attention
particulière devra être portée pour toute connection indirecte (par
exemple utilisation d’une multiprise)

Configuring the 1073OPX 1
To operate the 1073OPX, configure as follows:
Ensure the unit is switched off.
Connect the PSU to the mains supply.
Connect the supplied power adaptor (PS12221) to the rear 5-pin DIN
input.
Connect your mic/line or DI input source/s to the front of the unit. Separate
mic/line inputs MIC I/Ps 1-8 and LINE I/Ps 1-8 are available on the rear of the
unit on D-sub connectors. These inputs follow the DB-25 standard pin
configuration. Monitor inputs MONITOR IN L and MONITOR IN R are available
on the rear XLRs of the unit. On the front of the unit, Mic inputs use the XLR
combo connectors; Line and DI inputs both use the 6.35mm jack on the combo
connectors.
Connect the line output/s O/Ps 1-8 into your system. The outputs are
available on the rear D-sub connector. This uses the DB-25 standard pin
configuration.
Connect monitor outs if required via XLR cables at the rear of the unit
labelled MONITOR OUT L and MONITOR OUT R
Connect headphones to the front ¼’’ jack connector at the front of the
unit.
Switch on the unit. it will default to the last-used setting. Set front panel
controls as required.
Select front or rear input source by pressing the FNT button.
Select Input MIC/LINE/DI by pressing the IP button.
Set the phantom power +48v, 80Hz high pass filter, -25dB PAD and LoZ
impedance as required for each preamplifier.
Set phase by pressing and holding the IP button, it will illuminate red to
indicate 180° phase flip.
The DI circuit within the 1073OPX is a transformer-less class-A design. This uses an
FET transistor to increase the impedance to 650Kohms, perfect for guitars, basses
and keyboards. When connecting an instrument directly to the unit using the DI,
set the level at +40db gain and adjust gain levels from this point. If the signal is
distorted at 40dB then use the -25dB pad to reduce the incoming signal and then
add preamplifier gain to get the desired tone and level.

Front Panel 1
POWER: Switches the unit on or off. The button will light when the unit is
ON
HP LEVEL: Controls the volume of the headphones and rear monitor outputs
and attenuates from -35 to 0dB. Pressing the HP LEVEL control knob will cycle
through the monitor sources indicated by the adjacent LEDs:
Off/cut; No LED illuminated.
Channel-1 only; mono by default unless the MONO button is deselected; 1/2
LED RED
Channel-2 only; mono by default unless the MONO button is deselected; 1/2
LED GREEN
Channels 1 (left) and 2 (right); stereo by default unless the MONO button is
selected; 1/2 LED YELLOW
[this sequence repeats for channels 3/4 5/6 7/8]
MON - Monitor input; stereo by default unless the MONO button is selected,
routes the stereo Monitor input at the rear of the unit to the stereo monitor
output and to the headphone output Post-HP level control.
DMON –The Digital Monitor input is only available when the optional digital
monitor card has been inserted into the unit; once installed this option will
become available on the front panel. DMON is stereo by default unless the
MONO button is selected. DMON routes the digital stereo monitor signal from
the connected DAW/Computer through the D/A converter and to the stereo
monitor XLR outputs and headphone output post-HP level control.
Monitor source select is reflected in both the headphone output and the
monitor output at the rear of the unit.
MONO: Toggles between mono or stereo monitoring. The button will light
when mono is selected.
GAIN: Adjusts the sensitivity (gain) of the selected input in 1dB increments.
The sensitivity is indicated on the dual 7-segment display.
+48V: Applies 48V phantom power to the microphone input (front or rear,
whichever is selected). The button will light when phantom power is active.
This button is only available when mic input source is selected. Selecting a
different input source will automatically switch off phantom power.
