1073N Channel Amplifier Issue 1.4
1073N Channel Amplifier Introduction
The original Ne e 1073 channel amplifiers are ery popular sounding mic
pre's and are considered by many to capture the ery essence of the Ne e
sound. In manufacture since the early 1970s, the Class A design offers 3
bands of EQ with one fixed high frequency and a high pass filter.
The 1073N retains the same basic circuitry as the original 1073 while
utilizing modern manufacturing techniques to make it more affordable
While the 1073N can be used in any situation that the 1073 classic module
can be used, it features additional connecti ity which allows it to be used
as a stand-alone module.
These 45 series modules are the same as the original designs, and contain
many of the original components
Confi urin the 1073N for Stand-alone use
To use the 1073N without a rack or console, configure as follows:
u Set the EXT LVL CTRL switch to NO: Setting this to yes would route
the audio out of the back connector and there would be no audio output
from the 1073N.
u Set the 5k1 Termination switch to YES: This terminates the high
pass filter correctly where an external le el control is not present.
u Connect the supplied 48V power adaptor (PS10500) to the 48V input.
u Connect your mic/line or DI input source
- Mic input uses the XLR input of the XLR combo connector
- Line input uses the ¼ inch jack input of the XLR combo connector
- DI input uses the separate ¼ inch jack connector
u Connect the line output XLR into your system
u Switch on the 1073N
u Set the phantom power, DI earth lift, DI PAD and Mic I/P Z as
required (see rear panel description section for more information on these
features)
Neve Racks
Like the classic 1073/1084 modules, the 1073N can be used in AMS Ne e
3U and 5U racks and arious Ne e consoles.
The 3U rack houses two modules mounted horizontally in a 19” rack-
mounting unit. The 5U rack houses eight modules mounted ertically in a
19” rack-mounting unit. Both ha e rear panels with XLR Inputs and
Outputs.
The 3U rack rear panel has a fused, oltage selector IEC mains input
connector. The 5U rack has a free standing AC supply with a fused,
oltage selector IEC mains input connector and connects to the rack ia a
connector and a 1.5 meter cable.
Modules of any combination can be fitted into a rack unit.
The CH (chassis) and 0V are linked internally.

DC Power Supply Indicators (rack units)
u The red LED on the front panel of both 3U and 5U rack units indicates
+24V power healthy when illuminated.
u The green LED on the front panel of both 3U and 5U rack units
indicates +48V power healthy when illuminated.
u Phantom power can be supplied to each module by pressing the
phantom power switch on the front panel of the 3U or 5U rack. The LED in
the switch will illuminate confirming that phantom power is supplied.
u The mains switch on the rear panel of the 3U rack unit is non-
illuminating.
Output Level Control
u Each channel has an independent Output Le el Control. The control is
post-input, post-EQ and pre-output. This control can reduce the le el at
the output.
u When the Output Control is fully clockwise the output gain is
unity. The output is 20dB down with the control in the mid-
position.
Mains Volta e Adjustment
u Switch off unit.
u Remo e fuse.
u Turn inner barrel with screwdri er or coin until correct oltage figure is
under the white arrow on the housing.
u Replace fuse.
Fuse Rating: T0. A, 2 0v 20mm, Ø mm.

Confi urin the 1073N for Neve rack or Ori inal BCM10
When the 1073N is used in a Ne e 3U or 5U rack or an original BCM10
console the rear panel input and output connections, power switch,
fuse and phantom power controls are not used. The following
configuration should be used for the remaining controls:
u Set ‘EXT LVL CTRL’ switch to YES: This routes the 1073N audio
through the olume control of the rack or console.
u Set ‘5k1 TERMINATION’ to OFF: This remo es the 5.1kW resistance
from the signal path to ensure correct frequency response.
u Set Mic Impedance to match the microphones you are using: Low
impedance = 300W, Hi impedance = 1200W.
In most cases you would set this to Hi.
Confi urin the 1073N for Neve 45 series consoles includin the new 2016 BCM10
When the 1073N is used in a Ne e 45 series console without fader
connections (most 45 series consoles other than the original BCM10) the
rear panel input and output connections, power switch and
phantom power controls are not used the following configuration
should be used for the remaining controls:
u Set ‘EXT LVL CTRL’ switch to NO: This routes the 1073N audio
internally.
u Set ‘5k1 TERMINATION’ to YES: This terminates the high pass filter
correctly to ensure correct frequency response.
u Set Mic Impedance to match the microphones you are using: Lo
impedance = 300W, Hi impedance = 1200W.
In most cases you would set this to Hi.

Rear Panel Description
Power Switch: This is used to power on/off the unit in stand-alone mode.
It has no function when used in a rack or console.
+48V connection: Connect the supplied power supply (PS10500) to
power the 1073N in stand-alone mode. It has no function when used in a
rack or console.
Fuse: The fuse is for stand-alone operation of the 1073N. It has no
function when used in a rack or console.
Fuse Rating: T0. A, 2 0v 20mm, Ø mm.
Safety Warning: Always replace the fuse with an identical rating
fuse.
Power On LED: The power on LED will light when the 1073N is switched
on in stand-alone mode.
LINE O/P: Balanced line le el output of the 1073N when used in stand-
alone mode. This has no function when used in a rack or console.
Amphenol Back Connector: All power and audio connections are
pro ided by the back connector when the 1073N is used in a rack or
console.
EXT LVL CTRL: When in the YES position the audio signal is routed ia
the amphenol back connector so the le el can be controlled by an external
olume control or an external fader. If this is set to YES in stand-alone
mode there will be no audio present at the line output. When in the NO
position the audio is routed directly to the line output.
5k1 Termination Resistance: When used in a rack or console with a
fader, the fader adds approximately 5kW resistance to the signal path.
When used in stand-alone mode, or in a console without a fader
connection, you should set this switch to ON. This adds 5.1kW of
termination to the audio signal path to ensure a flat frequency response.
Earth Lift: Pro ides earth lift for the DI input. If you’re hearing buzzing
when using a DI input try toggling this switch.
PAD: Pro ides 20dB of attenuation to the DI input. When set to 0dB the
impedance of the DI input is approximately 1MΩ. When set to -20dB the
impedance of the DI input is approximately 10kΩ.
DI I/P: The DI high impedence input.
NOTE: When a jack is connected to the DI input it overrides
anything connected to the Mic input. Use the Mic side of the gain level
control when using the DI input.
MIC I/P Z: Select Hi (1200Ω) or Lo (300Ω) impedance for the Mic input.

This applies to both stand-alone and rack/console use.
XLR/Jack combo connection: Use the XLR connection for Mic sources
and the Jack connection for line sources.
Phantom: The phantom switch applies phantom power to anything
connected to the XLR part of the combo input. This only applies to stand-
alone use. When used in a rack or console phantom power will be set on
the rack/console.
Sleeve: For future expansion.
Rack Mount Instructions
u Ele ated Operating Ambient- If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack en ironment
may be greater than room ambient. Therefore, consideration should
be gi en to installing the equipment in an en ironment compatible with
the maximum ambient temperature (50 deg C) specified by the
manufacturer.
u 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.
u Mechanical Loading - Mounting of the equipment in the rack should be
such that a hazardous condition is not achie ed due to une en mechanical
loading.
u 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).
Troubleshootin
No audio at the line output
u Check that you’re turning the gain knob in the right direction. Turn it
clockwise (mic mode) if you’re using the XLR part of the combo connector
or DI jack input. Turn it anti-clockwise (line mode) if you’re using the jack
part of the combo connector.
u If you’re using the 1073N in stand-alone mode check that EXT LVL
CTRL is set to NO.
