Re: [TenTec] Mic Help

[Steve Berg <wa9jml@tbc.net>]

There is no need to bypass the D104 preamp.  I use amplified D104 mics 
with my Omni V and Argonaut II, and get excellent audio reports.  I have 
a deep voice and the mics work out fine for me.  The amplifier also 
helps match the very high impedance of the crystal or ceramic mic 
element and the low impedance input of modern rigs.  With the 
unamplified D104s, you often have to play around with a series resistor 
to tailor the response curve of the cartridge to your voice and the 
input impedance of the rig.
