qd Built-in speaker
During recording, the speaker can be used for monitoring the E-E
sound, and during playback for monitoring playback sound. The speaker
also sounds alarms to reinforce visual warnings.
If an earphone is plugged into to the EARPHONE jack, the speaker
sound is automatically cut off.
See "6-3 Operation Warnings" on page 6-14 for information about alarms.

1) E-E sound (Electric-to-Electric sound)
The term E-E sound refers to an audio signal that has passed though the
amplifier, but has not been recorded on the tape. In other words, you can directly
monitor the recording input signal, as opposed to the simultaneous playback
(output) signal.
