EV microphones OT??

[David Christ]

Going through things in storage I found an Electro Voice 630 HiZ and
an Electro Voice 664 microphone.  Can anyone give me a clue if they
are good for anything?

Nah ... they're just junk, especially if you only operate CW or digital modes.    Send them to me, and I'll pay the postage ... :-)



Or ... put them on eBay or QRZ or eHam or the boatanchors and AM reflectors on QTH.net.  You'll probably find eager takers on both if they are in decent condition.  

Or ... use them yourself.  Both are very good vintage microphones and can add a bit of "class" to even a silicon radio station :-)

The 664 would sound great with almost any ham rig, but it needs EQ,
because it's a flat mic. The EQ I just recommended for the CM500 is a
good starting point, but I would add boost of about 9 dB in the highest
band and about 5 dB in the band below that.

It's a balanced mic, so to connect it to a ham rig, connect one of the
signal conductors to the rig mic input, connect the other to the mic
return, and connect the shield to the chassis. No other matching needed.

I don't remember the 630, but my guess is that it would work too, and
would likely need similar EQ. Since it's hi-Z, it's probably unbalanced.

I have used the EV 630 on several rigs.  Mostly AM.  It does do a good job on
SSB with the K3, but needs tailoring/equalizing as mentioned.  It also is a
relatively flat response mike.  Have fun.
