ALC is usually not desired when recording music
(voice or instrument) because the transitions in
input level may be audible in the recording, and
can make the recording ‘hissy’ by raising the level
during quiet passages and recording ambient
noise.
The REC LEVEL controls do not work when the
LEVEL CONT. switch is set at ALC.
US default: LEVEL CONT. switch at ALC.
Europe default: LEVEL CONT. switch at
MANUAL.

14. INPUT button
The INPUT button lets you
select the audio input and
audio channels for record-
ing.
When the INPUT LOCK switch (a) is at OFF,
press and release the INPUT button to tab
through the input choices. When the desired
input is displayed switch the INPUT LOCK
switch (a) to ON.
Example
display:
mono with INT MIC
The nine input choices are:
mono with INT MIC input
stereo with LINE input
mono with LINE input (L only)
LR mono with LINE input (L + R mix)
DigiIn (digital input)
stereo with MIC input
DLmono with MIC input (dual level mono, L
only)
mono with MIC input (L only)
LRmono with MIC input (L + R mix)
Note: The PMD670 'listens' only to the selected
input. For example if the input selected is
LRmono with LINE input, and no input source is
connected to the LINE IN jacks the PMD670 will
record silence.
US default: mono with INT MIC input.
Europe default: stereo with MIC input.
What the input selections do:
Selects the input device(s) and channels
The input selection chooses which input(s) the
PMD670 is using for recording and how many
channels are recorded.
Selects the recording (file) parameters
The input selection also determines which set of
algorithm/file parameters are used (stereo file,
mono file, or digital file).
Recording (file) parameters:
stereo (recorded as a stereo file): stereo with
LINE input, stereo with MIC input, DLmono with
MIC input.
mono (recorded as a mono file): mono with INT
MIC input, mono with LINE input, LR mono with
LINE input, mono with MIC input, LRmono with
MIC input.
digital (recorded as a digital file): DIGITAL IN
input.
The default algorithm/file parameters are:
stereo file: MP2, 48kHz sample frequency,
128kbps per channel, and file extension .mpg.
mono file: MP3, 44.1kHz sample frequency,
32kbps, and file extension .mp3.
digital file: MP2, 44.1kHz or 48kHz sample
frequency (dependent on input source rather than
default or PMD670 menu selection), 128kbps,
and file extension .mpg.
Via the Algor/File Menu choice, the algorithm/file
parameters for stereo, mono or digital files can
be changed. See Algor/File Menu choice on page
