Rs Juice Box Or Sp Battery Box?

[DaikenTana]

I've recently found that 9 volts of power for a plugin-power mic is ideal, and that most MD recorders don't supply this through their Mic-In jacks. Is this solveable by using the Line-In? Does the RH10 output 9 volts or not?

I've been looking at the Sound Professionals Battery Module:

and the Reactive Sounds Juice Box:

They both supply 9v to a mic and do practically the exact same job. However, the Juice Box is $10 cheaper than the battery module, but I can't find out why. Has anyone had experience with these two who could compare them?

Thanks in advance for any help.

I would go for the juice box as it is cheaper and the circutry is the same just the quality of the components matter from box to box. I have never used either box but would assume from the reputation of reactive sounds they would use very high quality components.

You're right, a 9V power supply improves the mics' dynamic range, makes them suitable for recording loud sounds through line-in, where the mic-in would overload. However, through the line-in there's no bias voltage from the recorder. Electret microphones don't work without that dc voltage though. To supply it is the job of the battery box.

The electrical circuit of such a box is a very simple one, all there is needed is a condenser and a resistor for each channel. Although i didn't test these two models, there shouldn't be much difference in sound quality, if any at all. Just pick up the one which fits you better (built quality, size, price). Both should do their job quite well. Or build your own if you feel skilled enough.

Oh I see. So seeing as I'm using SP's TFB-2s (and planning on getting a Single-Point Stereo), a batt/juice box would be a good idea if going through Line-In? I've heard that Line-In generates less noise because it doesn't pass through the preamp which the Mic-In does.

Line-in and mic-in serve whole different purposes and thus can't be compared directly. Mic-in provides way more preamplification than line-in and thus naturally some noise will be amplified along with the signal. That doesn't mean the Signal to Noise Ratio will be worse in the end. Don't expect to use line-in universally for all purposes, it's pretty useless for quiet daily life sounds, all you'll get is a very quiet signal not significantly above the noisefloor. But for recording really loud sounds such as indoor rock cocerts the mic-in would overload easily, using the line-in works best there.

Hi guys,

just following this thread....I will add that you can also, use the juice box thru the mic-in as well. This would be when you wish to record quieter sounds. The benefit here is the bigger dynamic range that is obtained from the 9v power supply. Don't worry , you won't be pumping 9v into the mic jack, the circuitry inside the juice box supplies that power only to the mic's.

You asked why our model is $10 less. We run a less expensive business model than sound pro's, I think they have a retail outlet and that means bigger operating costs, and thus higher prices.

If your in the US you can order quickly and easily from our distributor http://www.minidisco.com/juicebox.html, and of course you can order thru us.

Thanks, and let us know your experiences?

Thanks a lot! I'll be getting an RH10 within a day or two so I'll see how things go and post back here.

Okay, I got my RH10 yesterday and what a sexy little beast!

I've been recording a lot with a pair of SP-TFB-2s, and I've found that sudden attacks of bass (like the slamming of a car door from the inside of the car) causes the preamp to overload. Going over bumps in the car also does it, only the meters don't show it. I fix this just by flicking on Low sensitivity on the RH10, but all that bass really means I have to bring the levels down A LOT. It doesn't bother me that much; I haven't been in any situation where I needed the attenuator I bought or a battery/juice box.... yet. Oh well, I'll see how things go over the next few weeks.

I take this thing everywhere!
