The Controls

Mic/Line sensitivity- Controls input level of the mic and line inputs. The mic and line inputs have
their own input on the rear panel as well as a separate input transformer. Each rear input has its
own section of control on the input switch. The microphone section gives 20 to 80db of boost in
5db steps, while the line gives +10 to -20db of adjustment.

Output- Functioning as a console fader this control is placed after the gain stage and before the
output stage. This allows for trimming of the input signal between the 5db steps of the input
switch, as well as allowing the user to run the input very hot (for extra coloration) without distorting
the recorder. For most applications this will be left in the full position.

High Eq- This is a high end shelving characteristic with five selections. 16k, 12k, 6k8, 4k7, 3k3 (standard
1073s had only 12k). A high shelving type equalizer adjusts the selected frequency and all others above it.
The pot gives up to 18db of boost or cut of the selected frequency.

Mid Eq- This is a mid frequency peaking characteristic with ten selections. 270hz, 390hz, 560hz, 820hz,
1k2, 1k8, 2k7, 3k9, 5k6, 8k2. (old 1073s had 360hz, 700hz, 1k6, 3k2, 4k8, 7k2). The pot gives up to 18db
of boost or cut.

Low Eq- This is a low end shelving characteristic with four selections. 220hz, 110hz, 60hz, 35hz. A low shelf
type equalizer adjusts the selected frequency and all others below it. These are the same points found on
classic 1073s.

Filter- This is a high pass characteristic with 3db loss at 300hz, 160hz, 80hz, and 50hz and 18db cut per
octave. These are the same settings as vintage modules.
