RECORDING

Input Controls

INPUT Selection

The PMD680 can record from a variety of inputs:

• XLR micorphone connection

• 1/4" microphone connection

• Internal microphone

• Line level source

• Telephone line

The INPUT switch offers selection of a telephone (TEL),

microphone (MIC), or line level (LINE) input.

Note

• The MIC switch above the INPUT switch is only active

when the INPUT switch is set to the middle (MIC)

position.

The chart below indiactes which input is effective for

each of the MIC switch positions.

MIC ATTEN (Attenuation)

The MIC ATTEN switch adjusts the base input level for

all the external microphone inputs only, i.e. the XLR

and 1/4" microphone inputs.

Adjusting the microphone attenuation allows

microphones with higher sensitivity to be recorded and

controlled the same way as microphones with lower

sensitivity.

ANC (Ambient Noise Cancel)

The ANC (Ambient Noise Cancel) switch microphone

inputs but does not affect the line input and telephone

input.

This ANC feature allows the recorder to filter out

unwanted backgraund noise. The available settings are

as follows.

• Band-pass (

) : Cuts low frequency (150Hz and

lower, ex : wind noise, proximity effect) and high

frequency (3KHz and higher)

• Flat : No filtering

• Low-cut (

) : Cuts low frequency (150Hz and lower,

ex : wind noise, proximity effect)

REC LEVEL Control

The PMD680 offers three ways in which to control the

recording level: manual (MANUAL), manual with a

limiter (LIMITER), and automatic (ALC).

• MANUAL: The recording level is controlled by the

REC LEVEL knob.

• LIMITER: The recording level is controlled by the

REC LEVEL knob but a limiting circuit in the PMD680

will not allow the input signal to overload (go past

the -12dB mark on the level meter). The recover time

is short so that the set record level is maintained as

much as possible.

The REC LED will dim when the Limiter is heavily

limiting the input signal.

• ALC (Automatic record Level Control): The recording

level in this mode is controlled exclusively by the

PMD680 and the REC LEVEL knob is disabled. The

recover time of the system is long so that the

recording level does not constantly fluctuate.

Setting the Record Level

• The optimum recording level is where the peak of the

input sound just barely flickers past the -12dB point

(highlighted in black in the display).

• The recording level should never reach the overload

point in the level meter (OVER symbol highlighted in

black). Reaching that point will result in digital noise

which is very uncomfortable for the ear.
