OUTPUT

The phono-type OUTPUT jack lets you

connect the meter to recording or other

measurement equipment. For example,

you might use an audio patch cord to con-

nect the meter to the AUX or high-level in-

put of a recorder.

Note: The meter response will not be flat,

due to the A- and C-weighting networks.

Set

RANGE so the maximum needle de-

flection is never greater than +4, to pre-

vent the built-in amplifier from clipping.

Use A-weighting for voice recordings, or

C-weighting for full-range musical materi-

al. The

OUTPUT jack can also be connect-

ed to high-impedance headphones, or an

oscilloscope, a frequency analyzer, or oth-

er test equipment.

RESPONSE

The RESPONSE selector has two settings:

FAST and SLOW. In the FAST position, the

meter reacts quickly to changes in the

sound level, showing you the peak sound

levels present in the environment. In the

SLOW position, the meter is damped and

indicates an average-value sound level.
