Title: Power Options for CM 300's
Post by: Mr.Fantasy on July 24, 2007, 10:18:50 AM
My dad has these Nakamichi CM 300's that require batteries to operate. However I guess they stopped making the normal battery and the supposed modern replacement batteries make the mics sound like crap.

Does anyone know any other options?

Is there anyway to get these to do Phantom power? I have heard of people putting "pigs" in the battery compartment. But I never heard if that actually worked or not.....

Anybody?

I find that hard to believe. These have worked just fine for me:

If you are looking for the batteries, try to Eveready 206 9v's.

If you are looking to get the p48 mod, talk to Busman or Steven Sank.

People on this board are great...Busman and some others....not to distract from them but Steve Sank is known as the master of this process.  He has been doing it for years....his web site is as follows:

One important question here is, do you want them to remain full-bodied or do you want them 'modded' into actives utilizing phantom adapters?

Yes... They can be modded either way. There are circuits that allow the mics to use phantom power and remain as they are. (But the "actives" look cooler) There is also an oldschool taper method that drilled a hole in the side and ran wires to a 9V battery and a bit of electrical tape. There is a lot of cool Nak info at my Yahoo Micbuilders Group

No clue....


.........I want them to sound great.....and I don't even know if they will....

How do mic's like these (Nak Cm100's) compare to modern day mic's?

Is there even a comparison?

'Sounding great' is certainly one's opinion, but having these mics modded to accept 48v phantom would allow these mics to run at their intended voltage (or moreso).  You can retain the bodies and operate at a solid 48volts, or have them made into actives which rids them of the bodies and allows for a much smaller setup.  However, the 'active' route utilizes phantom adapters which limit the 48v phantom to ~9-10v.

I, personally, think they sound great all around....whether or not they've been chopped.

Mr. Fantasy,

In top post you said CM-300.  In a lower post you said CM-100.  These are 2 different beasts.  The CM-300 take the special 9V batteries, but CM-100 can run off AA batteries.

Which do you have?  The bodies are labeled as CM-100 or CM-300, and on the attenuator bodies (the head) CM-100's have 2 wide slots, and CM-300's have 4 narrow slots.

Joe

Another name for Eveready 206 is "A1611".  As shown here http://www.lowcostbatteries.com/Batteries/evr206_bplus_p/evr206%20(bplus).htm
