722 User Guide and Technical Information

v. 2.67 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.
Logic Inputs
Configured as a switch-closure input, a pin can be connected to a switch that a user has wired to
assigned contact. This switch can then trigger the 744T to begin recording. Other functions can be
assigned as well from the Setup Menu. The switch-closure on a given pin of the CL-1 can be thought
of as just another key on the keyboard. Anything that can be assigned to a key can also be assigned
to a switch.
To configure a pin as an input, navigate to Ext Keyboard Assign in the Setup Menu. Select
a new Shortcut number, then locate the Login inputs amongst the assignable keys. Choosing
Logic In 1 would correspond to pin 1 on the CL-1, Logic In 2 would correspond to pin 2 on
the CL-1, and so on. After a Logic input is chosen assign the desired action that the Logic input will
control.
Logic Outputs
Configured as a switch-closure output, the CL-1 can drive LEDs, relays, or any other sort of device
which will accept a TTL-level or similar input. For example, the CL-1 can drive a big red LED con-
nected via a series resistor between the +5V output and a switch-closure output and light up when-
ever the recorder is put into record mode.
To configure a pin as an output, go to CL-1: Logic Out Assign in the Setup Menu. The Logic
Pin number is on the left hand side (“00”, “01”, etc). Each of these pins can be assigned to un-
defined, Stop, Play, Record, or Pause. Note that if a pin is assigned to be both an input (via the
Ext Keyboard Assign Setup Menu) and an output (via the CL-1: Logic Out Assign Setup
Menu), the pin will automatically default to an output.
Setup Menu Presets
Presets are useful shortcuts to speed setting the numerous parameters available in the setup menu.
The 722 has four built-in presets and one user preset per media.
Built-In Presets
The 722 is shipped from the factory with the factory preset applied. Its settings are listed below.
Three additional presets, film, reporter, and music presets allow for quick setup of typical param-
eters for the defined application. Presets are applied by entering the setup menu and selecting the
preset. All previous settings are lost when a preset is applied.
