So I have a EcoCharge unit coming in... hve the cable to power my MP2, getting a 6-cable with 2 Sony ends on it for SBM1 and M1... some say you can use the M1 w/ 6v just fine due to how its power connection is setup, some say you need a newer M1 or something... my M1 was purchased brand new from Terrapin in summer 2001...am I safe?

you can get a M1 cable that drops the voltage to 4.5 from a 6v eco

also someone said that you shouldnt power an m1 with 6v because it will damage your unit

I have been running a 6v with a split plug powering my D100 (same circuirtry for the most part) and mod sbm-1 with no problems.

I ran one on 6volts with no issues!

I have a friend that ran an m1 on 6v with no problems for a few years. his deck completely fried at Panic NYE last year though... weird that it would just happen after all that time but it makes me nervous.

So I guess what we are saying is...don't do it!

Why wouldn't you use rechargeable AA's? Much lighter & safe?

I have a d8 so excuse my ignorance if the M1 doesn't use AA.

Kindguy · « **Reply #8 on:** September 30, 2003, 01:23:14 AM »

sorry just noticed you wanted to run the sbm-1 with it as well.

Personally, I'm a big fan of running both the Sony portable decks and SBM-1 on AA rechargables.

But if you really really want to use the 6v batt to power the M1, it's supposedly pretty easy (per Doug Oade and others) to add a couple of diodes in-line on the hot (+) wire to drop the voltage down to ~5v which is low enough to not potentially damage the M1. Unfortunately, I have never done this myself and don't have part numbers on the diodes.

sorry, but M1 sucks up AA's. if sending analog out I would be lucky if I got more than 90 minutes of power from AA's.
been running a M1 on a 6V 7.2AH SLA for 2 years with no problems. hell, the SLA paid for itself after running it for *1* festival!!

nic · « **Reply #11 on:** October 01, 2003, 12:53:27 PM »

m0k3...Ive used all types of Duracell and Energizer AA's in my M1, even their high-end ones...cant remember their exact name as I havent used them in years.

if I didnt send a analog out I could get 2 hours or so on a pair. if I sent a analog out, 90 minutes TOPS!

I'm averaging OVER 15 hours per charge on my 6V 7.2 AH ;-)

utahtaper · « **Reply #12 on:** October 21, 2003, 01:07:29 AM »

I have used a 6v 7.2 for almost two years and still running strong with my M1

RobC · « **Reply #13 on:** October 22, 2003, 12:19:04 AM »

this is what I do for my M1,

I got a 4 x AA battery sled at radio shack added the plug to go into the M1 and run 4 x 1700 mah recharagables in it, that puts out 4.8 volts and I can record a 3+ hour show (with analog patches) pluss have enough juice left over to tlisten to the tape on the ride home.

Kevin · « **Reply #14 on:** October 23, 2003, 09:43:59 AM »

you should try the power plant battery, its the size of a CD and puts out 4.5v, I love this thing. ill get a link for you in a sec

i've been running both my M1 and D100 from a RadioShaq 6v sled i made. total cost was about $5 w/o batteries. i just use 4 Duracell D-sizes.

if you're savvy enough electronically, you can add a voltage regulator chip to maintain a constant voltage of 5v, but IMO it's perfectly fine to run the M1/D100 on 6v.

the sled i made has been going for about 17hrs and counting. i've yet to change the batteries.

You should not have a problem running the 6v cable. Actually the 6v runs a little more like 7v and the 4.5v cable runs around 6v. I tested both and found little problems with M1's. However you should try to run it with a 4.5 to be closer to specs if you can. The 4.5v just puts two diodes in the mix to drop the voltage a little.

Hope that helps,

Eric

Final answer- shouldn't be a big problem.

You don't need part numbers for the diodes. Just go to RS and get some 2A rectifier diodes. A pair in series will give a 1.4V drop from the voltage at the battery terminals.

If you prefer a constant voltage, you can build a 4.5V regulator using an LM317 and a couple of resistors. There is an equation on the regulator spec sheet. You plug in your numbers and get the resistor values.

I have that cable for my ecocharge, I don't use it, let me know if you want it. I'll trade a couple of shows for it...

>>his deck completely fried at Panic NYE last year though... weird that it would just happen after all that time but it makes me nervous.<<

didn't necessarily happen because it ran off 6 volts...

Tim · « **Reply #21 on:** December 21, 2003, 05:18:14 PM »

certainly not... but I've never seen a deck spontaneously combust before.

im looking for that cable for my d100 for my bp-50 if you still have it

BCostigan · « **Reply #23 on:** December 26, 2003, 06:56:58 PM »

Almost every other piece of gear has a voltage range within about 8 or so volts of the optimum voltage. I don't see why the m1 would be so sesitive that a +1.5v would matter...but then again that's just a guess.

I do know that the ua-5 and ad-20 both call for 9.6 and 9 volts but both function perfectly off 12 volt slas.
