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. [. . . ] The CH (chassis) and 0V Link should be connected or instability may result.

Phantom Power
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.
