RF Emissions and the 702, 722, and 744T Recorders


Note: While this article mentions Lectrosonics products specifically, the facts and solutions apply generally to most professional wireless receivers.

Sound Devices 702, 722, and 744T hard disk recorders have broken new ground for size and performance of modern digital audio recorders. As with the introduction of many new product categories, however, some things that were taken for granted in the past may have to be re-thought moving forward. One area where the modern recorder is different than that of earlier generations is in its use of computing power.

702 or 722 Upgrade to Time Code


Is there, or will there be a possibility to upgrade the 702 or 722 to time code in the future?


It is not possible to upgrade the 702 or 722 to include time code. They have unique circuit boards. If time code is a required feature, consider the 702T, 744T, or the 788T, which include time code.
