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.

Settings
Extra MId Points- With the added flexibility of the LTD-1 you may now use the mid and high eq to greater effect. For
example on a kick drum or bass guitar you may now take out the mush (390-560hz) while still adding upper end eq
even into the mids (3k3 or 4k7).
Filter trick-The low eq and filter can be used in conjunction to turn the low shelving control into a "low peaking
control." For example at 110hz you select the filter setting just below that (80hz) which will make 110hz into a
peaking type characteristic. This technique lets you have much more versatility with your low end eqing………
General filter use- The filter is very useful for taking out "booming" low end. On vocals and acoustic guitar it will take
out this boom without removing the thickness and strength of the track. 50 and 80hz are usually most useful for this.
Telephone and thinning effects- The 300hz and 160hz selections of the filter are excellent creating "effect" sounds.
Distortion sounds- You can easily create intense distortion sounds by cranking up the input and turning down the
output fader. Combine this with the filter, telephone, and eq tricks and you can create many interesting and different
sounds.
Color your sound- You can drive the input slightly to add vintage color and distortion to the sound.
