C451(x) clarification please

[jbohn]

Alright let me see if I can figure this out with some help from you guys. In the AKG C451 series, there seems to be the 451E, 451EB, 451C, and 451B. If there's others, what are there? Also, the E and EB have interchangable capsules and the B is not, right?

The only thing I know 100% is that the B has a -10 and -20dB pad, and a 150Hz and 75Hz rolloff.

I've seen some people who swear that their 451E has a low cut but I thought that the EB and the B were the only ones that had a rolloff.

Last thing I'm fairly positive that I've seen a 451 that 150Hz rolloff, a 75Hz rolloff, flat response, and a -10dB pad that was all on one selector switch. Which I thought was weird but kinda cool/different.

Also, when I was just looking around and found an E with a -20dB pad.

I know this is just dumb semantics but it seems there's so many different versions maybe someone else had the same questions. Thanks in advanced.

I have a C451 EB. Capsules are interchangable, and it has a 75Hz and 150Hz rolloff.

That is all.

I think this is the C535. I have 3 of these and thats what they do.

I also have 3 451EB and they have interchangable capsules and a 150hz and a 75hz roll off

C451 C = kleintuchel DIN connector
C451 E = XLR
C451 EB = XLR + pad, rolloff
C451 B = the new version, fixed capsule, pad, rolloff

Some History



The first mass-produced transistorized AKG microphone, the C 451, was launched in 1969.The C 451 was at first only available with a nickel plated body in two versions: The C 451 C had a DIN connector that was still a standard in Europe at the time even though it was of rather poor engineering quality. The C 451 E already featured an XLR connector.The C 451 was designed for universal phantom powering at 12 to 48 volts, although it worked at voltages as low as 7.5 volts so it could even be powered from a 9-volt battery which was already available everywhere at the time.

The C 451 system (also called the CMS Condenser Modular Series) comprised a preamp and several interchangeable screw-on capsules. It was made until 1993 and then replaced with the AKG Blue Line. However, the specific response of the CK 1 remained in demand for certain applications to this day.


The C451B uses a back-electret capsule. It is not a condensor.Thus it is ensured, that the diaphragm is ident regarding material and dimensions with those of externally polarized caps.

Sweet, thank you very much guys.
