'all-in-one-deck' + DSM mic
portable recording system
for noise-free results
an external PA-3SX or
PA-24NJ preamp for
both powering the
mic, and improving
the audio
quality/versatility over
common noisy, gain-
limited internal deck
preamps.
Correct, direct DSM powering as purchased stock
EXCEPTIONS are SONY's PCM-D50 and LATEST PCM-
M10 models. These two flash deck models POWER DSM MICS
PERFECTLY, AND have adequately quiet internal mic preamplifier !!!!
WHAT IS MOD-2 UPGRADE for
Sony DAT Models?:
The upgrade places additional
surface mounted components (SMC)
'in-tandem' with the existing Sony
circuit to boost the mic supply
performance specific to DSM mic
powering. Nothing else is changed
AND Sony has honored (to this date)
all warranty/services agreements
regardless of having this upgrade
installed.
I did have only two occasions
(in 10 years) where there was need to
send Sony the upgrade's technical
details describing the true scope of the
upgrading procedure in response to a
temporary denial of honoring an
extended warranty service contract.
SONY DAT decks are sent here
;
48 hour turnaround for MOD-2
service upgrade.
NOTE: MOD-2 doesn't affect
warranty, serviceability, or shorten
the battery running time by more
than a few minutes.
Typical MOD-2 mic powering battery
drain is LESS THAN 1/150th of the
total deck power.
MOD-2 upgrade is $125 USD for
TCD-D100 & PCM-M1 DAT.
EDIROL R-09/R-09HR & MARANTZ PMD-620 MOD-3/4 DSM POWERING
UPGRADE
R-09 was the first,then PMD-620, and now my current favorite Edirol R-
09HR flash models are practical for internal mic power circuitry upgrade
for direct
'plug-in-mic-powering' of DSM
™ mics.
STOCK R-09, R-09HR, PMD-620 are NOT compatible for
working direct connection powering of DSM microphone; TOO much
current is applied causing mic to not operate.
MOD-3/4 internal deck upgrade increases current control so DSM
mic operates simply plugged into the MIC minijack input. Mic power
is then turned on using the deck's menu.
MOD-3/4 is recommended for recording applications needing
simplicity of lowest profile/size of deck+mic two piece recording
gear where internal noise performance of the deck is not an issue.
Having R-09, R-09HR, or PMD-620 upgraded is
suggested for recording moderate low-to-extreme loudness
ambient/effects, and musical sounds. And when the modest noise
performance of deck's internal mic preamplifier is found adequate
for the intended purpose.
