Introduction
These 45 series modules are the same as the original designs, and contain all of the original components.
1073 Channel Amplifiers
These very popular sounding mic pre's are considered by many to capture the very essence of the Neve 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.
1084 Channel Amplifiers
Based on the same technology as the 1073s, the 1084s again deliver the unique sound and quality of Neve. However, the 1084s offer additional features, including 3 switchable EQ bands with cut and boost, a high Q for presence and low pass/high pass filters.
High Pass Filter (resistor modification)
Important Note
The high pass filter in both the 1073 & 1084 modules is a passive design and as such must be correctly terminated to achieve a maximally flat response.
In order to achieve this there is a 5k1 resistor fitted inside the module on the back connector between pin E (0v) and pin K (fader send) see diagram below:
In situations where the fader connection is not used (most Neve 45 series consoles except BCM10's) then the resistor remains in place.
In situations where the fader connection is used (BCM10's and AMS Neve 1073/1084 racks) then the 5k1 resistor should be disconnected and replaced with a fader or potentiometer whose value is 4k7 / 5k ohms.
Failure to do so will result in incorrect levels and uneven frequency response.
Installation
The 1073s and 1084s are available as stand-alone modules, or in a choice of two housings.
The 3U rack houses two modules mounted horizontally in a 19" rack-mounting unit.
The 5U rack houses eight modules mounted vertically in a 19" rack-mounting unit.
Both have rear panels with XLRs for transformer balanced I/O.
The 3U rack rear panel has a fused, voltage selector IEC mains input connector. The 5U rack has a free standing AC supply with a fused, voltage selector IEC mains input connector and connects to the rack via a connector and a 1.5 meter cable.
Modules of any combination can be fitted into a rack unit.
Additional Information
*Rack Mount Instructions *_
A) 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 (Tma) specified by the manufacturer.
B) 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.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
D) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
E) 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).
Recommended Tma = 50 deg C
Mains Voltage Adjustment
1.) Switch off unit.
2.) Remove fuse.
4.) Replace fuse.
3.) Turn inner barrel with screwdriver or coin until correct voltage figure is under the white arrow on the housing.

Mains Supply (rack units)
The 3U rack has a fused, voltage selector IEC mains input connector.
The 5U rack has a free standing AC supply with a fused, voltage selector IEC mains input connector and connects to the rack via a connector and a 1.5 meter cable.
The mains switch on the rear panel of the 3U rack unit is non-illuminating.
The CH (chassis) and 0V are linked internally.
DC Power Supply Indicators (rack units)
The red LED on the front panel of both 3U and 5U rack units indicates +24V power healthy when illuminated.
The green LED on the front panel of both 3U and 5U rack units indicates +48V power healthy when illuminated.
Phantom Power
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.
Output Level Control
Each channel has an independent Output Level Control. The control is post-input, post-EQ and pre-output. This control can reduce the level at the output.
When the Output Control is fully clockwise the output gain is unity. The output is 20dB down with the control in the mid-position.
Modules In Transit
Please note that the designs of the AMS Neve classic modules and racks are to the original Neve specifications and are not designed to withstand transit.
Should you wish to move the rack from one location to another (for example shipping to another studio location or returning the rack to a repair center for servicing), please remove all installed modules from the rack and package the rack and each module separately in packaging suitable to withstand the intended transit.
If modules are installed in a rack while in transit, damage to the internal edge connectors may occur.
