        Does exactly as described. ***dont leave the battery in overnight, there is no "off" switch, and the battery will run dry if you do***

          I just used this on a shoot and it really saved the day. I used it for my boom mic and by eliminating a direct xlr connection I could have the mic placed independent to our cameras. I highly recommend it.

                Comments about Denecke PS-1A - Portable Single Channel 48V Phantom Power Supply:

                One 9-volt will give me phantom power for a full day, which is optimal compared to draining the batteries in my Tascam DR100mkII or Sound Devices 302. It's simple, basic, built like a tank, and works.

                My only complaint is that you have to remove the 9-volt to turn it off. With this situated in my sound bag, it'd be tremendously more convenient to simply have an on/off switch located on the top.

                Comments about Denecke PS-1A - Portable Single Channel 48V Phantom Power Supply:

                Saw a pro audio guy using this Denecke PS-1a on a shoot powering his Audio-Technica AT4073a shotgun (which he swore by and preferred to his Sennheiser MKH-416's) even though he was running the output into a Sound Devices 302 --which has excellent and flexible phantom powering.

                He said something special happens when he activates the -15dB switch that even the engineers at Denecke cannot explain: the signal to noise ratio goes UP -- the voice remains strong and clear while the background noise goes down compared to the voice. He said he uses this configuration when in very noisy environments.

                Will have to try it. I always wondered why you would ever want to attenuate a shotgun as you are seemingly trying to capture as much signal as possible from a distance. Our aged T-power supplies for our old T-powered Sennheiser 416's and 816's have attenuation switches. Now I know why.

                Comments about Denecke PS-1A - Portable Single Channel 48V Phantom Power Supply:

                I bought this to use with my DR-100mkii. Even though the Tascam can provide phantom on its own, this severely cuts the battery time down.
                Now I can provide phantom with the Denecke, and record for hours on the Tascam w/ it's own battery supply.

                The PS-1A is great. Small form, and could not be simpler to use if you tried. There are three minor drawbacks I see:
                1) No On/Off switch. You have to remove or reverse the battery to prevent drain. Seems like an easy addition, but certainly not a deal-breaker.
                2) The orientation of the inputs is such that you cannot use a 90-degree female to go out of the PS-1A and into the Recorder. Another thing that's not a huge deal, but something I didn't realize until after I bought it. Made me unable to use my 1.5' XLR w/ 90-deg female, and buy another that had two straight connectors.
                3) For such a simple product, it seems a bit pricey.

                Overall though, I'm very happy with this product.

                  I built a new audio recording set up. Little did I know it didn't supply phantom power to my shotgun mic. I also do a lot of on location filming and can't always access a wall outlet. This thing does the trick. 1 battery lasted me about 20 hours. I love the low battery indicator light. I didn't notice any added coloration to my audio. On the downside, the pad switch is inside the case, though I don't really use it.

                        I use it for ambience recording with an ultra low noise mic where a low noise floor is paramount. will remove belt clip as I dont need it.

                          My application was powering a current-hungry studio condenser mic before a Lectro RF transmitter. The Denecke is tiny, ruggedly built with no moving parts, and works exactly as described. The only downside is cost, but there's very little else on the market for battery powered phantom supplies of this quality.
