Anybody ever run the PSP-2 at 5Volts? Any issues?
According to the manual the supported volatges are 5 - 9 Volts.

I was surprised to see that the PSP-2 can be powered by 5V, 500 mA which conforms to USB standard powering. I can't think of any other preamp in this size/performance category that has such minimal power requirements (Aerco, Sonosax, PSP-3, any others...?).
A while ago, I bought a slim USB battery pack for use with my iPod (APC UPB10). I hacked together a USB to DC jack (from an old AC adapter that I found to fit). Surprisingly, it powers the PSP-2 for quite a while, with Phantom 48V on. I recorded for 8 h, and the battery was only half drained. I'm sure there are smaller USB battery packs with more capacity nowadays since this is a pretty old battery.
Any other experiences out there with powering a PSP-2 with 5V? Any effect on sound quality or SPL handling?

The Sound Devices MixPre, MP-2 and Shure FP-24 are all spec'd to run at 5V.
I'd guess the USBPre 2 does as well since it is powered via a USB connector (but I wouldn't put it in the same category as the rest).

Mine lasts a ridiculously long time on 6 AAs, I'm not sure I'd ever use an external power source unless absolutely necessary. I am using it at 12v (w/ cmr's and a pfa) instead of 48v, but I think I could probably get 14-20 hours from 6 AAs easy.
Aside from the standard battery sled issues (i.e. not forgetting to flip it backwards when not in use), I think it's more reliable powering source than an external battery with a cable that could wiggle or come unplugged. If you flip the sled backwards, I recommend putting some electrical tape on the back side of the sled just to be certain.
That said... damn those pictures are sexy. :)

I think the tree-hugger in me tries to find a rechargeable solution whenever possible. I like devices that I can power with both internal and external options. I usually hook up an external supply, and rely on the internal batteries to act as a safety net in case something happens to the external.
I'll probably run the PSP-2 with the external and internals -- I just gotta remember to remove that sled when not in use!!!

Nothing really to add to this except that I just ran the PSP-3 at 6V using a 10Ah 6V SLA for the entire weekend at All Good. That was something like 44 hours of music spread over 4 days. Couldn't have been a better experience and the battery only cost me $30 at BatteriesPlus.

Thats awesome, I wish my new Lemosax ran on 5-6v :P I just got my Lemosax and mk41's and dvd battery today! ;D I was wondering tho, is the ring positive or negative on the sax ???
Sorry for the highjack

When not in use, I simply flip the battery sled backwards. I've put some duct tape on the back end of the sled because there are some metal contacts. Electrical tape might be a wiser decision, but this has worked well nonetheless. I've left the sled in the unit backwards for a few weeks and there is zero drain.
My poor sled is really busted.. I definitely need to order a new one soon!

Thanks for the tip! I'll just have to remember to flip it every time. Is there a secret to pulling out the tray? I'm using a screwdriver to pry it out. I was thinking of putting a string or thread around one of the holes so that I can just yank it out.
My offer still stands to run to my Fry's and pick up a generic sled for ya!

It might be that my sled is so badly damaged, but I've never had any trouble removing it from the unit.
A string sounds like a decent enough idea; just make sure there's no way to accidentally damage the sled while setting up for a recording!

string sounds like a good idea :)

Has anyone powered a PSP-2 with the Tekkeon mp3300 via its supported voltage ranges of 5, 6, 7.5 or 9?
-
I've run the PSP-2 using the related MP3450 at 5 V. On the MP3450, there is a USB port so I usually used this to the PSP, then used the custom DC out to power something else. But it definitely should work with the MP3300 at 5 V.

Yes, will power it for a long time. I have only run mine at 9v
