Just tried to rest out a Beomic 2000 I bought, I cannot get any sound out of it. Before I contact the buyer I want to make sure I am not doing something wrong. It is fitted with a 3 pin DIN plug. Looking at the position of the pins, I thought it should work trough the AUX connection on by Beocenter 9300. Am I wrong in thinking this. Any help greatly appreciated.

If it's a dynamic mic (I believe it is) it could use all three pins as a balanced output, although either of the signal pins and ground will work (at a lower level). However the signal will be very low (mV rather than volts).

Easiest way I can think of (without risking damage to you B&O gear) is to try it into the mic input of a PC which has plenty of gain (you will have to make a lead to convert Din to 3.5mm jack, and just use one signal line and ground). Also, search through the PC mic input settings, there may be a 20dB boost which could need enabling for a dynamic mic).

The pinout is incorrect (so you will only get signal to the left channel, possibly not even there) and in addition, the signal level from a dynamic mic is so low that you probably wouldn't hear anything from a line level AUX input anyway.

If you don't have a microphone preamp or any Beocord with a proper mic input, I guess the best you can do is measure the resistance between pins 1 and 3 (opposite on the connector). I believe it should show something around 200-600 ohms, I couldn't find the specs specifically for BM2000.

(the 3 pin DIN for microphones is usually chassis ground on pin 2 and balanced mic output on pins 1 and 3, while 5-pin DIN inputs are on pins 1 and 4 - so you probably have only one end of the microphone capsule connected anywhere now)

Not hugely relevant to you as a seller, but if the buyer is planning on using it for recording, it'll probably need a re-ribbon regardless of whether it's currently working or not. Ribbon elements in all ribbon mics wear out after a while, but there are plenty of people about who will install a new element for you.

It's really, really important though that you don't put any voltage across the microphone. I believe the Beomics are transformerless, and plugging them into anything producing a voltage (such as a mixer with phantom power switched on) will wreck the ribbon.

Good luck, I've been drooling over the sound of the Beomics for some time - they're great microphones! The Royer designs are based on the B&O microphones, and they've been used on many, many notable records for their distinctive sound (Thriller as an example).

Thanks for the replies, the only other B&O mic I have had was a Beomic MD8. To test this I plugged in to the Phono connection on Beomaster 1000. Is the MD8 wired differently? As it too had the same 3 pin DIN plug.

Found some leads and a DIN joiner thingy. Connected it up to my PC and it works perfect. Still can't make my voice sound good, but I doubt there is a mic anywhere that can do that. Thanks for the very helpful replies anyway
