    Denecke PS-1A reviews

    PS-1A - Portable Single Channel 48V Phantom Power Supply is rated 4.7 out of 5 by 21.
    Rated 4 out of 5 by from Perfect, with one minor annoyance 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.

    Rated 5 out of 5 by from Why the -15dB switch is key 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.

    Rated 5 out of 5 by from Perfect in concert with my DR-100mkii 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.

    Rated 4 out of 5 by from Awesome for filming/portable audio! 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.

    Rated 5 out of 5 by from nice solution I use this both as for an on camera mic and for double system power to a KMR-81. This is simple, transparent, and sounds good. I have had phantom power supplies in the past with dirty switches. I like that the battery can be reversed to turn the unit off. Its a simple and clean solution. The unit is sturdy. It would be nice if it had a place to mount a rod attachment for a rig. I wound up gluing a clamp to it.

    Rated 5 out of 5 by from Saved the day 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.

    Rated 5 out of 5 by from High quality power source Does just what it is supposed to do. Case is rugged metal. The battery sort of snaps in which makes it easy to change; it's an odd design, not sure what my opinion is about it yet but seems to work okay. I'm using this with a portable video camera set up and remote mic. Belt clip makes it easier to carry/wear if you are powering a hand-held or lavalier but frankly I wouldn't want to be wearing this thing if it could be avoided. Oh yeah, don't forget to remove (or reverse) the battery or it will be dead next time you go to use it. Not a bad design because it eliminates the need for a switch which could get intermittent or break. You just need to remember to shut it off when you're done.
