1073® OPX Introduction 1
The 1073® OPX is an 8 channel Microphone, Line and instrument preamplifier
with optional digital interface. The unit is housed in a 2 unit 19’’ rackmount
enclosure. The 1073 OPX has 8 1073 preamps featuring 8 Genuine 1073
transformer-coupled microphone/line preamplifiers with Marinair®
transformers on the input stages and an electronically balanced output stage.
The 1073 OPX DI Input is transformer-less Class-A design which allows for +30
to +60dB of gain, front mounted dual concentric inputs allow for easy
connection to electronic instruments.
The 1073 OPX is a fully digitally controlled preamplifier unit which enables
remote use and full recall capability via the proprietary 1073 OPX remote
control software.
Most functions of the 1073 OPX can be controlled directly from the front
panel or by remote control using a Mac or PC with the Neve® Remote-
Control software. This provides a simple and elegant solution for users of
DAW, broadcast or live sound reinforcement systems.
Up to 8 1073 OPX units can be connected to the remote -control computer,
giving up to 64 Mic Pre-amps or Line Level inputs, all controlled from a single
point. The unit always powers up with all settings, levels and states as they
were at power-down.
The digital option enables the device to be used as a Dante enabled Audio-
over-IP preamplifier with both Primary and Secondary network capability. In
addition, the digital card USB port enables the 1073 OPX to function as a
primary standalone audio interface for any DAW enabled computer.
The 1073 OPX has both an analogue and digital monitor return path. This
function allows the device to be used as both an analogue monitoring system
and as a primary audio interface for any MAC/PC DAW system.

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)

9
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 preamp.
Set phase by pressing and holding the IP button, it will illuminate
red to indicate 180° phase flip.
The D.I circuit within the 1073 OPX is a transformer-less class-A design. This
uses an FET transistor to reduce the impedance to 680Kohms, perfect for
guitars, basses and keyboards. When connecting an instrument directly to
the unit using the D.I, 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 preamp gain to get the desired
tone and level.

the 1073 OPX as a primary audio device.
DANTE PRI/ DANTE SEC: Primary and secondary Dante audio-over-iP
connections to connect the 1073OPX as a Dante-enabled device.

13
Monitoring 1
The 1073 OPX rear panel has two female XLR connectors labelled
MONITOR IN L and MONITOR IN R. These can be used to feed a
monitor path from your audio interface into the 1073 OPX unit. The
Signal is fed into the units MON audio path and can be attenuated by
-35dB via the HP LEVEL control. This signal is then fed to both the
headphone output on the front of the unit and to the MONITOR OUT
Land MONITOR OUT R outputs on the rear of the unit. This signal
path can be used to feed a monitor Loudspeaker set.
Latency Free Monitoring 1
The 1073 OPX monitor path can be fed from a combination of preamp
or monitor inputs signal sources. This makes the unit capable of
latency free monitoring, allowing operators to record overdubs by
listening to the input source directly pre-DAW. Users can blend the
mic, line or D.I preamp signals directly with the monitor or digital
monitor signal for quick latency-free monitoring.
When the unit is powered down, the monitor input selection is
remembered for the next time the unit is powered up.
The Diagram to the left shows the connections of each individual
preamp output into the monitor path. The outputs are connected as
stereo pairs with 1, 3, 5, 7 connected to the LEFT MON/DMON path
and 2, 4, 6, 8 connected to the RIGHT MON/DMON path. This
configuration allows for accurate latency-free stereo imaging at the
signal source. If a mono signal is required when monitoring either a
single preamp output or combination of signals, simply press the
MONO button.
Activating MONO will convert all monitor path signals into mono,
including MON and DMON
Pressing and holding the HP LEVEL control and then pressing any
channel gain encoder will add the selected preamp channel into the
units monitor MON or DMON signal path. Multiple preamp inputs can
be selected at any time to form stereo pairs or mono signals
monitored in the left or right monitor path. The different signals being
inputted into the HP Monitor path are indicated by LEDS on the HP
LEVEL control section. MONO can be activated at any time.

14
To add preamp signals into the monitor path-
Press and hold the HP Level control
Then press GAIN POT of the preamp channel you with to monitor.
Add additional signals by repeating the process.
Multiple monitor indicator LEDs will display which signals are
being fed to the monitor path.
When mono is selected manually by the operator, the incoming
MON (Monitor) or DMON (Digital Monitor) signal will also become
mono.
Example 1- MON is selected and channel 1 gain encoder pressed. This
activates channel 1 preamp output into the Left monitor path.
However, since the MONO button has also been pressed both
preamp output 1 and the monitor (MON) signal will both be heard in
both headphones and monitor our left and right in mono.
Example 2 –MON is selected and channel 1 and channel 2 encoders
have been pressed. Since these can now form a stereo pair of preamp
inputs, they have been added into the monitor path as channel 1 to
Left Monitor, channel 2 to right monitor.
Example 3 –DMON is selected (fed from digital USB or DANTE) and
channel 1&2, 3, 7&8 are selected. In this example two stereo pairs of
preamp inputs (1 & 2 and 7 & 8) and one mono preamp 3 have been
added into the monitor path. Since we now have two stereo pairs and
one mono source, channel 3 signal will monitor through the LEFT HP
LEVEL output and MONITOR OUT L only. MONO can be selected by
the operator if several preamp inputs are selected and added into the
monitor path.

15
Summing 1
The Monitor output XLR connectors at the rear of the unit follow the
front HP LEVEL monitor signal selection. This function gives users the
ability to use the unit as a 4x stereo analogue input summing mixer.
Users can pass audio signals through the 1073 line-level transformer-
coupled preamplifiers, combining them into the monitor path through
the Left and Right Monitor output XLRs on the rear of the unit. This
stereo signal can then be fed into the DAW and recorded back as a
summed stereo track.
Due to the hard wiring of the unit, odd numbers are fed to the Left
monitor output and Even numbers are fed to the Right monitor
output.
Preamp Outputs 1, 3, 5, 7 > MONITOR OUT L
Preamp Outputs 2, 4, 6, 8 > MONITOR OUT R
Any combination of up to 4 stereo pairs of input signals can be
summed together by using this technique.
Individual mono signals will appear in either the left or the right
only.
MONO can be activated by the user which will sum both left and right
output signals together to be sent equally to both Left and Right XLR
outputs.

16
