I was just estimating the gain range -- those values aren't an exact measurement! I just wanted to demonstrate that within the gain range that I normally operate, the PSP-2 has pretty big steps.

Tell you what -- I'll try to use a signal generator and see if I can measure the gain range.



I contend that because of the stepped gain of the PSP-2, you need to do fine level adjustment at some point after the PSP-2.

Nice work on figuring out the gain range Ted!

The PSP-2 was originally designed to work with the DAT recorders of the early nineties. Gain is set on the PSP-2 and then you use the potentiometer on the DAT deck for trim. However, I wouldn't haul around a V3 for this function unless you intended to go digital out to the recording device.

The gain ranges I estimated were pretty close.

I set up my computer to generate a steady tone, then from my DAC (Headamp Pico), I fed an unbalanced signal to my V3, and then SPDIF out to my PMD-661. I adjusted the signal to a specific level on the meter using the gain and the trim on the V3. Then I placed the PSP-2 between the DAC and V3 and measured the signal increase. I used the balanced outs on the PSP-2.

Mic sens "-35": gain of +28 (ie., the meter increased from -40 dB to -12)
Gain switches +6 and +12 add +6 dB and +12 dB respectively.

Mic sens "-55": gain of +48 (the meter increased from -60 to -12)
Gain switches +6 and +12 add +6 dB and +12 dB respectively.

Mic sens "-70": gain of >+60 (the meter increased from -60 to "over"; I adjusted the trim on the V3 downwards by 4 dB, and it was right around 0, so I estimate that it adds about +65 dB)

That's the best I can do with my equipment I have on hand.

So the revised gain range for the PSP-2 is:

+28 (Mic sens: "-35"; Gain "0")
+34 (Mic sens: "-35"; Gain "+6")
+40 (Mic sens: "-35"; Gain "+12")
+48 (Mic sens: "-55"; Gain "0")
+54 (Mic sens: "-55"; Gain "+6")
+60 (Mic sens: "-55"; Gain "+12")
+65 (Mic sens: "-70"; Gain "0")
+71 (Mic sens: "-70"; Gain "+6")
+77 (Mic sens: "-70"; Gain "+12")

So there probably is a pretty big margin of error and it would be nice to get an actual number for the peak value instead of estimating it by eye. I would say +/- 5 dB. I tried feeding the signal to another computer but couldn't really get the digital in or line in to work.

Well done!   I was going to that, but I'm so glad I didn't need to :)

+28 (Mic sens: "-35"; Gain "0")

Heh.  I knew that thing was damn hot at min gain.

so, are there any other hand held recorders out there that have spdif/coax in other than the M-Audio Microtracker?  Eventually, I'm going to upgrade recorders.  So far, sony pcm-m10 and tascam dr-100 are looking nice.  anybody used the dr-100?  hell...may even splurge on the dr-680???  ok, the 680 may be a stretch at the moment...but, you never know....

I know...but, those two have caught my eye.  Aside from those not having digi in and the M-audio...I was wondering if there were any other hand helds that might have digi in?  I haven't gotten the opti mod on my v3 and would rather find a recorder that had digi in, etc.

I am looking for the same thing. It seems the smallest and best is the marantz pmd-661

Yes but isn't it optical

It is.

In general, the MT2, D50, and PMD661 are the smallest/cheapest 3 recorders that take a digital connection of some sort and are 24bit..

I did this math 8 months ago when I thought about adding an additional 2 channels to my capabilities.  :-[  :-\

the marantz pmd-661 is looks nice...spdif in as well as xlr ins.  that would work for my psp2>v3 combo.  I wouldnt have to run the odl-276 between the v3 and recorder anymore.

I still think running through 2 preamps is a mistake.  If you're going to keep the PSP-2 you should sell the V3 and get a Mytek.
