directly to R-09 MIC input (no PA-3SX preamp); turning OFF R-09 mic power
decreases input loading, so PA filter does not reduce bass as much, meaning filter
frequency (cycles/Hz) is now lower than shown on PA filter label. So with R-09 mic
power off, you might want to use next higher filter setting as filters are now less
aggressive to reduce bass sounds. Suggest best way to use PA filter directly into
R-09 deck mic input jack is with R-09 mic power ON so bass filter works better to
reduce bass. And filter frequency is nearly same as is shown with PA-3SX preamp
input connection.
In other words, you can use PA bass filter connected directly DSM
mic and then filter output to PA-3SX preamplifier and get good LINE
level for recorder, and also you can connect your PA-6LC3B directly to MIC
input on deck (with/without mic power turned on) to get desired excessive bass
reduction function while recording.
Please let me know when ready to order. Cost of PA-3SX with EMS shipping is
$475.00USD.
Send prepayment as before.

OLDER MODEL PA ADAPTER TIP
IN-SERIES PA adapter modules are for powering DSM mics; some have low-cut bass filters
The 3.5 mm input Jack should be kept from
disconnection or movement by using one of the
two moveable cord securing straps as illustrated in
the two photos.
NOTE: Newer PA-6LC2
and other 'newer box'
type PA adapters have short 8-10 inch length
output cords, and are not supplied with cord
securing straps.
BASS FILTER ADVISORY
It seems that "a bit too much that bass filtering" is an easy thing to do when all you got to do is
slide a switch and viola! ........ there's now less bass in the recording. Microphone BASS Filtering can be a good
thing to even up the overall "tone" balance of a recording AND it also gives more analog input or recording
"headroom" that helps to enhance the overall resolution of higher frequencies.
In other words, you can turn up the REC level a lot more FOR MIDS AND HIGHS because the
strongest (bass) sound component is now at a much lower deck input level.
Sometimes it's not that you can do it (reduce the bass content with a filter), but it's really about
knowing WHEN and WHEN NOT and HOW MUCH TO reduce bass sounds. If the sound is SO loud
that your hearing gets distorted OR if you are prudent in saving your ears with wearing earplugs (especially when
right-up close to the stacks), you MAY NOT be HEARING the overall tonal balance of the venue WELL ENOUGH
TO MAKING the most appropriate bass filter selection.
Too many recordings I've lately heard seem to error on WAY TOO
MUCH BASS FILTERING as to lose most sense of the real "GUT and emotional
