Re: [Elecraft] Koss SB-45 Headset, update on comfort

[n3xx]

Most operation here is CW & digital, and sometimes SSB, so I need to be 
able to move the mic up and out of the way when not needed.  Can any 
SB45 users tell me if the mic can be moved to a full vertical position? 
 I have looked at pictures, but can't tell how far it will move.

Electret and dynamic mics are equally good for ham radio. Use whatever

electret mics need bias turned on and dynamic mics do not.

I bought a SB-40 awhile back. The headphones sound great but the mic is 
totally unusable. The volume is extremely low and muffled sounding.


I'm thinking of getting a hacksaw and opening up the microphone case to 
see if there is something wrong inside.

Hi Jim,

Electret and dynamic mics are equally good for ham radio. Use whatever 
comes with the headset you like and be happy. All that matters is that 
electret mics need bias turned on and dynamic mics do not.


Do you know why Elecraft calls the power provided to an electret element 
BIAS? Unlike the large form condenser microphone elements that need both 
polarizing potential and preamp power, usually provided via a "phantom 
power" circuit, an electret element is permanently polarized. The power 
applied via the phantom circuit is actually providing only the drain 
voltage for the FET preamp in the electret microphone capsule, not any 
kind of biasing voltage.


Of course we have similar terminology used in systems that provide 
control voltages or operating power to remote equipment: The so-called 
BIAS-TEE used to inject and extract power over a coaxial cable, for 
example.


I haven't found any official documentation for these types of circuits 
that uses the BIAS moniker. Are there any references that you might 
point to?


Cheers,
Gus Hansen

Gus, 
  
I think the term bias, or bias voltage is a pretty generic term when meaning 
applying a voltage or current to turn on a device, in this instance a 
microphone element that requires voltage to operate.

Re: [Elecraft] Koss SB-45 Headset, update on comfort

[Bob McGraw K4TAX]

One other point is  many professional type condenser or like type mikes 
do have internal active amplification.  They require a couple of 
miliamps of operating  current as opposed to just placing a charge on 
the element.   In this case it is normal for the mixing console to 
provide "phantom power" which is sent along the mike line between the 
console and mike.  For those consoles that do not have internal phantom 
power systems, a separate external source is required and provided.

That's exactly the reason, Gus -- electret elements have VERY high 
output Z, so they have a built-in FET follow circuit to get the source Z 
down to the level that it can drive the load of an audio stage. The 
circuit it's driving provides a positive voltage to operate that FET, 
through a resistor, typically around 5K, that serves as the load Z for 
the FET follower.


And, BTW -- pro electret mics, whose outputs are balanced, also include 
preamps with output Z designed to drive pro mic input stages. The output 
Z of the preamps built into those pro mics is typically in the range of 
100 - 400 ohms.

[Elecraft] Koss SB-45 Headset, update on comfort

[Dave Hachadorian]

Last week I posted my impressions of the Koss SB-45 here:
http://marc.info/?l=elecraft=145134615022993=2

I promised an update on long-term comfort after the RTTY Roundup 
contest, so this is it.  I wore this headset for two 12 hour 
contest sessions this past weekend, and found its comfort equal 
to or better than the Yamaha CM-500, which most everyone, 
including myself, seems to think is very good.  There is a sweet 
spot in the headphone height adjustment, where equal pressure is 
applied above and below the ears, and it feels really super at 
that point, even for an eyeglass wearer like myself.  My ears 
didn't get as hot as with the CM-500, and the SB-45 headband has 
nice soft padding that didn't irritate the top of my bald head 
like the CM-500 sometimes does.


Overall, I think the SB-45 is equal to or better than the CM-500, 
at about half the price.

Thanks for the review of the headset, Dave!
