Incredible Neumann Vocals For Less!

Neumann released the BCM 104 with broadcast professionals in mind. What they didn't necessarily expect is the number of home, project and professional studio owners who have fallen in love with what the BCM 104 does to studio vocals! If your studio lacks that "Neumann sound," the BCM 104 is the perfect microphone to add to your arsenal today for a lot less than you might expect!

Neumann BCM 104 at a Glance:
  • The BCM 104 uses the same capsule as the coveted Neumann Solution D microphone!
  • Integrated pop screen
  • Amazingly low noise microphone
  • Unique suspension gives "vintage" vibe to your studio!
Killer Neumann Capsule

The Neumann BCM 104 microphone headgrille houses the K 04 large-diaphragm capsule, which has a flat frequency response up to 3kHz. Higher frequencies have an increased presence of 2dB maximum. Since the above-mentioned microphone characteristics are obtained without the use of resonance effects, the microphone features excellent transient response and transmits all transient phenomena of music and speech without any coloration.

The integrated Pop Screen

A pop screen not only prevents the occurrence of plosive pop noises in vocal recordings, but also efficiently prevents unwanted particles, from respiratory moisture, nicotine, to food remnants, from settling on the diaphragm. The pop screen can be removed for cleaning without the use of tools.

Electrical Features

Instead of a transformer to couple the microphone output to the supply voltage, the Neumann BCM 104 has an electronic circuit which, like a transformer, provides for good common mode rejection. Interference induced in the balanced modulation line is thus suppressed as usual. With a very low self-noise of 7dB(A), and an overload capability extending to 138dB SPL, the Neumann BCM 104 has a dynamic range of 131dB.

Filter and Preattenuation

The Neumann BCM 104 amplifier has a linear operation down to 20Hz. An active filter efficiently suppresses signals below this frequency. In order to compensate for the proximity effect, a highpass filter, electronically activated by a switch, is built into the microphone. This filter reduces frequencies below 100Hz by 12dB/octave.

A 14dB preattenuation switch is provided in order to adjust the sensitivity, if necessary, to transmission circuits designed for dynamic microphones. But this will increase the self noise by 14dB. Both switches are located inside the microphone housing.


The preferred mode of operation is to suspend the BCM 104 from a standard studio boom arm. A thread adapter to fit different connector threads is included. In order to provide protection from structure-borne noise, both the capsule and the microphone in its mount are elastically suspended.

Neumann BCM 104 Features:
  • Cardioid microphone for incredible studio vocals, voice overs and broadcast professionals.
  • Large diaphragm condenser capsule with switchable proximity compensation
  • Distinctive design
  • Integrated pop screen
  • Quick release head grille for easy cleaning
  • Individual head grilles available for each user
  • Requires +48V phantom power

A great step up

When it was time to upgrade my audio book studio to a mike that would better match my voice, I worked with my Sweetwater engineer and looked at a few prospects, finally settling on the Neumann BCM 104. As soon as I set it up, it was obvious that this was exactly the sort of sound I was looking for. Instead of trying to make the cheaper mikes work out, I should have gone right to this Neumann mike to start with - but, as always, Sweetwater made the upgrade experience easy and pleasant!

A real sleeper

Having used all matter of LDCs for Voice Over and Audiobook recording, there are always issues that prevent me from using them and reverting back to dynamic standbys SM7b or RE-20. Cheaper condensers just don't have the sound quality suitable for the professional product that big clients demand, whereas u87s or similar (and the required pop filters and stands) are too big for ideal placement in a small booth. Unfortunately, with quieter voices, the dynamic mics require loads of gain from the preamp, which can introduce noise from a variety of places. The BCM-104 solves all these issues flawlessly. The sound seems to be tailored perfectly for the human voice, and the tight cardioid polar pattern rejects reflections rather well. Compared with the similarly priced TLM-103, the BCM-104 simply works better on every source I've tried it on, and compares very favorably to the u87i on cardioid setting in most applications. While the mount might be awkward for some instruments in a music setting, I've found that the frequency response is far, far more musical than any other microphone in its price range. Matching this mic with the right pre for the source bodes very well in post production. The "air" and "body" seem to remain intact even after heavy limiting and EQ. This mic gets very little attention on the online boards, as it's been marketed mainly to broadcast and voiceover professionals. No one I know uses one in a music application OR in broadcast/VO. That might be a shame, but I'll be using this for years to come, and will likely pick up a few more before they catch on and get expensive after they're discontinued.

Excellent Product!

Excellent mic. I use this for voice-overs and it produces big time! There are plenty of other good mics out there and i have used many of them. But this one i cant seem to get away from. It is definitely worth the price and you will not be disappointed. I would recommend a pop filter/ windscreen of course with this and any mic.
