Radio Shack Sound Level Meter - Output Jack and Response Settings

10
Controls
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.
