Oval Office/White House Recorder
Sony TC-800B Audio Recorder
The secret White House taping system used a Sony TC-800B audio recording machine like the one on the left It was a simple machine that was not expensive and cheap tiny Lavalier mics were used that were hidden throughout the Oval office and Nixon's hideout office in the OEB. The recordings were made on thin 0.5-mm tape running at the unusual speed of 15é16 inch per second - half the speed of a cassette recorder. The slow tape speed degrades the recording's already poor signal-to-noise ratio.This accounts for the poor quality of the tapes.
