In the recent Marine Sound Collection Newsletter, there is a reference to
new compact flash recording devices. One is the TASCAM HD-P2. This is a
device for which I was anxiously awaiting release for more than a year,
since my company is a TASCAM dealer. However, I am very disappointed by the
official frequency response specifications and do not recommend it based on
price vs. performance. Even though is has a 192kHz sample rate, the
frequency response at 80kHz is down by 20dB. It's even down by 4dB at 40kHz.
See specs from the device manual below.
MIC to LINE OUT: 20 to 40 kHz 0.5 dB/-4.0 dB (88.2 kHz/96 kHz)
20 to 80 kHz 0.5 dB/-20 dB (176.4 kHz/192 kHz)
Since this is a response from mic in to line out, there is the possibility
that the mic in to recorded file response may be flat to 80kHz. However,
until somebody can measure this, I would stick with the Fostex FR-2 or other
known device for best price vs. performance.
Best regards,
Joe
