External Time Code Auto-Record Modes
The 7-Series recorders include two "auto record" time code modes. When the units are in either of these modes, recording starts and stops automatically based on whether time code from an external source is running. This mode is helpful in rec-run video environments to chase a video camera.
CL-1 Pin Configuration
The CL-1 Remote Control and Keyboard Interface for 7-Series recorders is commonly used to interface PS/2 compliant keyboards for external control. The unit has six programmable electrical contacts used to automate menu items or control the record, play, and stop functions.
Locating Sound Devices Product Serial Numbers
Sound Devices product serial numbers are 12 digit sequences located on white bar code stickers. The bar code sticker is located on the back of 7-Series recorders. When a battery is in place, the serial number sticker is not visible. The bar code sticker is located on the bottom panel for all other Sound Devices products.File Format Overview
With a near complete shift from tape-based digital (DAT) and analog recording formats to file-based digital audio recording formats, the choices of audio file types have exploded. In the recent past, audio engineers would set their DAT recorder to 48 kHz, record its two audio tracks as either dual-mono or stereo, and would then concentrate on the business of getting great sound. With a file-based work flow, there are other elements that need to be considered to ensure a smooth transition from the field or studio to the editing suite.
442 Tone Oscillator Polarity
The polarity of the 442 and 442N mixers tone oscillator is inverted between the main outputs and the direct outputs. This polarity "flip" only affects the tone oscillator and not audio signals.
