11. ANC switch
The ANC (Ambient Noise
Cancel) switch lets you
reduce ambient noise
before recording on the internal microphone or
MIC inputs.
Ambient Noise Cancel positions do not change
the memory used in recording. Examples of low
ambient noise sources include: traffic, air condi-
tioning hum and wind noise.
Band pass position reduces the lows
and highs and passes (records) the center (voice
level) audio frequencies. This reduces the re-
cording of high and low frequency ambient noise.
FLAT: No filtering applied.
High pass position reduces low fre-
quency ambient noise only.
12. EDL PLAY switch
The EDL PLAY switch
turns EDL PLAY off or on.
OFF: When the EDL PLAY switch is at OFF,
PMD671 playback does not respond to EDL
mark instructions.
ON: When EDL PLAY is ON, PMD671 playback
follows EDL mark instructions regarding play-
back order, skipping sections of recording on the
memory card, or repeating a section of recording
on the memory card.
Note:
If the EDL PLAY switch is at ON and there are no EDL
marks on the CF card (recording was done with the AUTO
13. LEVEL CONT. switch
The LEVEL CONT(rol)
switch lets you select the
type of input level control.
MANUAL: At MANUAL, you control the input
level with the REC LEVEL controls.
LIMITER: At LIMITER, peak sound levels that
would distort the recording are limited.
ALC: At ALC (Automatic Level Control = Auto-
matic Gain Control), the PMD671 automatically
responds to changes in input level. If recording is
quiet, the input level is increased. If recording is
loud, the input level is decreased. This is a desir-
able feature when recording a meeting with
several speakers. A speaker close to the micro-
phone and/or with a loud voice will be automati-
cally recorded at a reduced level and a quiet
speaker will be recorded at an increased level.
Both will be less likely to have their input missed.
ALC is usually undesirable when recording music
(voice or instrument) because the transitions in
input level may be audible in the recording. ALC
can also make the recording ‘hissy’ by raising the
level during quiet passages and recording ambi-
ent noise.
The REC LEVEL controls do not work when the
LEVEL CONT. switch is set at ALC.
MARK switch at OFF, or no marks were placed manually),
playback is not available. Switch to OFF for playback.
Factory default: EDL PLAY switch at OFF.
