Three capsules in one microphone, to record everything – from single vocals to symphonic orchestra. The BPT-microphone solves it all – with accuracy and grace.

Based upon a design of Dr. Edwin Pfanzagl-Cardone, head of the acoustic department of the Salzburg Festival (Salzburger Festspiele), Nevaton designed a unique microphone which gives a direct reference to the inventor in its name – Nevaton BPT (Blumlein-Pfanzagl-Triple)a three-capsule mono, stereo- and surround-microphone with centre-zoom function

In countless recordings at the Salzburg Festival Dr.Pfanzagl-Cardone developed a microphone technique which proved to be exceptionally successful. In short words it is a further development of the well known Blumlein stereo-system.

The Nevaton BPT provides a beautiful stereo (or surround) image, a result of the largely decorrelated signals (especially at low frequencies) of the crossed figure-eight patterns.

By adding a third center-capsule the sound-engineer now has the possibility to add as much acoustic focus to the centre image as needed.

This is very useful because even though the Blumlein Recording technique is known as one of the most natural sounding microphone techniques, the centre image is often not as much highlighted as it should be. The BPT now makes it possible to compensate for that effect and give as much weight to the centre image as desired. Therefore it is now also possible to highlight sound-sources in the centre of the stage (an effect which can be described like a zoom function of a camera) in the post production stage and/or directly when live-mixing a performance.

The microphone has switchable directional patterns, which means that the centre capsule can be switched to cardioid, wide cardioid, to figure-eight or to omni characteristics, the side capsules can be switched from figure-eight to cardioid as well.

The BPT microphone offers two further advantages:

– the extremely low self-noise of only 7dBA
– the matte-grey surface finish gives it a very ‘non-intrusive’ look which can be a key-factor in artist acceptance for live-recordings.

In addition the strong directional characteristics make it possible to position the BPT at a large distance from the sound source and still get a satisfactory direct/diffuse-sound ratio. Therefore the BPT is ideal not only as a traditional main-microphone system (possibly with additional spot-microphones ), but even more so, if the sound-engineer is restricted to capture the whole sound event with just one microphone as a „one-point“ recording.



The NEVATON BPT is delivered in a fine wooden box, together with a shockmount and 40 cm long break-out cable.
