Lemosax/Sonosax with 9v alkalines ???

[page]

Bean, About 5 hours is what I used to get running 9 volts. I use two 9v dvd batteries now and it works fine. Just need a cable made to run both.

Well done. Any specific model battery you use or just generics?

[andyjah]

Just the Inital RB-270s . These seem like they will run forever. Never tried to run them down all the way.

Yeah, thanks alot Andy I am going to use 9v's for moedown since I cant afford a dvd battery before then I scored [8] x 9v's at Walgreens for only 14 bucks Just cheap generics. I will do a batt tests or two first as always tho, so Im not surprised at the festival!

Also, Andy, Is that info with cheap alkaline 9v's or Duracell/Energizer  9v's

TIA,
Bean

Duracell I think. BJ's always has a huge multipack at a reasonable cost. Enjoy the sax Bean. Still love mine after 8 years with it.

Oh I will DEF take great care of it I used to run a Sax from my 481/3's>Sax>722 for awhile back in 2006

Using 2x generic 9v's, I am getting 12.5 hrs right now and its still going strong, even tho the low battery light is flashing like crazy I am SOOOOO PSYCHED I am getting this long of runtimes I can do ALL of MoeDown w/ just a few pairs of 9v's

[F.O.Bean]

I got around 14hrs TOTAL running 2x generic 9v's So just to be on the safe side, I'm switching out my batteries after 10hrs This means I'll only have about 4 battery changes at moedown this labor day

Bean you might want to ask Jon Merin about using 9Vs with the Lemosax. I think he had his die prematurely using generic 9V at Summer Camp one year. Are you getting 14 hours under load at high dB volume?

I asked a similar question (albeit inelegantly) regarding SPL levels (load) and preamp gain and how it affects battery life here:

Anyone care to dumb things down a bit and help me understand if/how a high dB/SPL affects battery performance of a preamp (or in my case an AIO pre/ad/recorder [SD 722])?

[F.O.Bean]

Levels were being PUSHED, at around -6db on the M10

FYI on the Walgreens Alkaline 9v's and AA's. I was told years ago that they're just house-branded Duracells. Typical way for Duracell to do that would be to take the cells that don't pass their statistical quality controls with flying colors, and brand them for Wags.

I used to be able to get the 8-packs of 9-volt Walgreens Supercells for $12 (they crept up from $8) but occasionally they'd do two-for-ones and I'd snarf up a year's worth of preamp power. But now Walgreens doesn't seem to have the 8-packs, and the 1 & 2-packs are unreasonable. Bearing that in mind, i found out that Radio Shack puts their house brand on two-for-one sale about 4 times a year, and I asked the local Shack Geeks to give me a call when that is happening. Note: I have not yet tried the RS batteries for my preamp.

There's a difference between the standard and lemosax versions.  I've always gotten 10+ hours with the lemosax.

From the sx-m2 manual:

16. SPECIAL VERSIONS SX-M2/LS
Designed for use by sound engineers, working frequently with the same pair of condenser or electret microphones, this version provides the same high quality amplification and features as the SX-M2.
The difference between the two versions is that the SX-M2/LS allows the user to directly connect the capsules without the microphone body thus creating a significant diminution of power consumption.

Makes sense
