hi, some "PIP" recoders provide more than 3v. The Sony D100 provides 5v. A =
few others do too, but I'm not familar with the others. Someone else might =
comment on those.
As for a staging amp between a mic and a recorder mic input, if I were you,=
I'd skip the recorder's mic input ( going by my rough gist of where you ar=
e coming from, here ) and get a sweet sounding preamp that outputs a roughl=
y line level signal into the line input of your little recorder.

Yes the preamp is between the mic and the recorder which normally supplies=
PIP for the mic but with the preamp which one supplies the power. A boost =
from mic to recorder is what I desire. Does the batery box you describe doe=

etween the PIP microphone and an existing PIP input?
PIP has some fundamental limitations. It is basically defined by a 3 Volt =
supply and a 2k pullup resistor. The resistor gives rise to a minimum noise=
floor, and the 3 V supply limits the maximum voltage to about 1 V rms. If =
those were the only limitations then the performance could be very good. A=
so called battery box helps by allowing a higher battery voltage and perha=
ps a higher value pullup resistor. As an example, the Primo EM172 is spec'd=
at -28 dBV/Pa and 80 dB SNR and 122 dB SPL maximum acoustic level. But th=
at is with a 5V supply and a 3.9 k resistor. With 3V and 2k all of those sp=
ecs will degrade slightly.
You could build a battery box with those values and get the specified perf=
ormance from the mic capsule. But there will still be a limitation on the m=
aximum signal that can be accepted by the preamp in the recorder. That is, =
the preamp will clip. If you only want to record quiet sounds, then the ove=
rload will probably not occur.
To do a complete job on the interface design we need more info on your mic=
rophones and recorder. |

| =A0 Hi all
I have been toying with the idea of a preamp to go with a Sony and
Telinga EM23 setup but having a lot of trouble finding any that are
suitable for PIP 3.5mm gear, all phantom XLR types. Any suggestions.
Cheers
David
