CDR420 has HI and LO adjustable microphone
equalizer fi lters with adjustments from 0 to ± (plus or
minus) 10 dB.
Increasing the high equalization increases the recorded
volume of high frequencies. That can be desirable in
music where you want your microphone to hear, for
example, the low volume high notes of a violin soloist.
That can be desirable in surveillance when you want to
record, for example, footsteps or doors opening.
Decreasing the high equalization decreases the re-
corded volume of high frequencies. That can reduce
unwanted high frequency noise, such as wind, hums,
clicks and scratches.
Increasing the low equalization increases the recorded
volume of low frequencies. That can be desirable if
you want to strongly emphasize the bass sounds of
music, or recorded low frequency sounds such as thun-
der or explosions.
Decreasing the low equalization decreases the re-
corded volume of low frequencies. That can reduce
unwanted noise, such as rumble from heating systems,
or traffi c noise.
CDR420 has HIGH PASS and LOW PASS fi lters.
These can be turned on or off to reduce ambient noise.
HIGH PASS ON "passes" high frequencies
and reduces low frequency noise only. Use to reduce
unwanted noise, such as rumble from heating systems,
or traffi c noise.
