1081 Channel Amplifier |
Introduction |
Introduction
The 1081 channel amplifier was first produced in 1972 to provide the mic/line-amp and EQ sections in Neve consoles such as the 8048. A look through the credits on today’s top selling CDs will reveal that these vintage consoles are still widely used to great effect and that the 1081 module has become a hugely popular design classic. This is why AMS Neve have resumed production of the 1081, using the original components and construction methods.
Installation
The 1081 is available as a stand-alone module, or in a choice of two housings that provide power supply, phantom power switching for each module and connectors for balanced inputs (mic and line) and outputs:

Mains Supply (rack units)
The power supply unit is a universal input type therefore no mains operating voltage setting is required.
The mains switch on the front panel of the 3U and 7U rack units is non-illuminating. The CH (chassis) and 0V Link should be connected or instability may result.

Mains Fuse (rack units)
The mains fuse is located in the IEC mains input connector on the rear of the 3U and 7U rack units.
Secondary Protection Fuses (rack units)
Secondary protection fuses for the 24V and 48V supplies are located behind the front panel on the power supply filter PCB SZN825-058 in both 3U and 7U rack units.
DC Power Supply Indicators (rack units)
The red LED on the front panel of both 3U and 7U rack units indicates +24V power healthy when illuminated.
The green LED on the front panel of both 3U and 7U 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 7U 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 allows the input and EQ to operate at a higher level and then for the signal to be returned to a normal operating level at the output.
When the Output Control is fully clockwise the output gain is unity. The output is 10dB down with the control in the mid-position.

EMI Filter Components |
EMI Filter Components
Jumpers may be fitted on the SUN870-081 I/O boards to allow the EMI filtering (three terminal capacitors and common mode inductors) to be ‘removed’ from the signal path. This may be desirable for those seeking sonic purity. However it must be noted that the immunity of the product to external RF fields could suffer, and if this is the case then the jumper links should be removed.
The individual 1081 modules are offered for inclusion in the customers own housings. As such no claim is being made regarding the immunity of these units. This will be principally governed by the type of cabling, connectors and enclosure used. The use of screened cables and connectors is recommended for all connections. Tests have shown that no problems with emissions as defined in EMC standards should be present with these units.
