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)

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 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.

AD/DA USB/Dante card (Optional) 1
The 1073OPX USB/DANTE card provides a digital interface for the 1073OPX
and has 8 A/D preamplifier converters and 2 D/A monitor converters. By
default, the post-gain amplified signal from the Mic/Line input is routed to
the A/D inputs. If this digital board is not fitted, then the Sample Rate and
Sync Source LEDs on the front of the unit will not light or function.
Word Clock In: The BNC connector provides an input to the internal sample
rate clock for synchronisation to external devices.
Word Clock Out: The BNC connector provides an output from the internal
sample rate clock for synchronising external devices to the 1073OPX internal
clock.
H/R: The digital headroom selector toggles the DMON stereo digital input
and Preamplifier 1 to 8 digital outputs headroom from +18dBu, +24dBu or
+26dBu.
USB AUDIO: Provides USB B connection for MAC or PC enabling use of the
1073OPX as a primary audio interface.
DANTE PRI/ DANTE SEC: Primary and secondary Dante audio-over-iP
connections to connect the 1073OPX as a Dante-enabled device.

14
Monitoring 1
The 1073OPX 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 1073OPX 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 L and MONITOR OUT R outputs on the rear of
the unit. This signal path can be used to feed a monitor Loudspeaker set in
the control room or a performer cue mix system in the live room.

15
Latency Free Monitoring 1
The 1073OPX monitor path can be fed from a combination of preamplifier
output and monitor input signal sources. This enables latency free
monitoring of preamp signals, allowing operators to record overdubs by
listening to the input source directly pre-DAW. Users can blend the mic, line
or DI preamplifier 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
preamplifier 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 preamplifier 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 (for more than 1 second) and
then pressing any channel gain encoder will add the selected preamplifier
channel into the units monitor MON or DMON signal path. Multiple
preamplifier inputs can be selected at any time to form stereo pairs or mono
signals monitored in the left or right monitor path. The signals being fed into
the HP Monitor path are indicated by LEDs on the HP LEVEL control section.
MONO can be activated at any time.
To add preamplifier signals into the monitor path-
Press and hold the HP Level control (for more than 1 second)
Then press GAIN POT of the preamplifier channel you wish 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, the incoming MON (Monitor) or DMON
(Digital Monitor) signal will also become mono.

16
Example 1 1
MON is selected and channel 1 gain encoder has been pressed. This
activates channel 1 preamplifier output into the left monitor path. However,
since the MONO button has also been pressed, both preamplifier output 1
and the monitor (MON) signal is sent as MONO to the headphone left and
right and monitor (MONITOR OUT L & MONITOR OUT R) outputs.
Example 2 1
MON is selected and preamplifier gain 1 and 2 encoders have been pressed.
Since these signals can now form a stereo pair of preamplifier inputs, they
have been added into the monitor path as
Channel 1 - Left
Channel 2 - Right
Both signals can now be monitored in the headphone and monitor outputs
in stereo.
Example 3 1
DMON is selected (fed from digital USB or DANTE) and preamplifier channel
1&2, 3, 7&8 are selected. In this example two stereo pairs of preamplifier
inputs (1 & 2 and 7 & 8) and one mono preamplifier 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 at any time, but all stereo
signals will be converted to MONO through the 1073 OPX Headphone and
Monitor outputs.

17
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 input analogue summing mixer. Users can pass audio
signals through the 1073 line-level 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.
Preamplifier Outputs 1, 3, 5, 7 > MONITOR OUT L
Preamplifier 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.

18
1073OPX Remote Control Software 1
The 1073OPX proprietary Remote-control software application can be run
