The Altmann YBV Microphone

Welcome to the Altmann YBV High-Performance Studio Reference Microphone.

The Altmann YBV unites the rich and full sound-signature of large-diaphragm studio condenser-microphones with the precision, speed- and transient-response of high-performance measurement mics, combined with previously unachievable timbre-accuracy, superlative-sensitivity and ultra-low noise.

A triple acoustic element with a proprietary filter design, enclosed in a specially treated 36mm wooden sound-board, self-contained transformerless, capacitorless signal-path and direct-drive balanced output circuit to be 48V phantom powered.

The Altmann YBV microphone is eminently suited for highest quality sound recordings in recording-studios, broadcast-stations, podcast-, live-, conference-, field- and nature-recording, creation of ultra-high-quality samples, as well as scientific and measurement applications.

Its small size makes it especially useful in situations where a large diaphragm microphone would be in the way of camera focus and/or too bulky for useful desk real-estate.

Designer's Statement

The Altmann YBV is a novel-design microphone that includes three separate small-diaphragm capsules spanning up an area similar in size to that of a large-diaphragm condenser microphone. This layout enables the YBV to create a similarly big sonic impression, but with more precision and faster response compared to conventional large-diaphragm microphones.

The Altmann YBV's output level is 3..10 times higher than that of conventional condenser microphones when subjected to the same sound pressure. The YBV's three precision signals (generally in phase) are summed up, however at the same time the inherent noise (generally stochastic) cancels itself out.

This makes the Altmann YBV a highly desirable microphone when ultra-high sound quality, absence of noise and unrivalled faithfulness to the acoustic event are required.

A recording engineer generally chooses a microphone according to the specific application and sonic requirements. A secondary channel with the Altmann YBV microphone is able to provide a witness to what's really going on 'in the air' as the complete informational content is delivered as a reference which is eminently suited for inclusion into the final artistic product.

This fun track (click on pic) was created from a single C1 sample recorded with the Altmann YBV-B shown below.

Below a performance recorded by Tobias Becker using the YBV-microphone and yes .. it was placed exactly as shown in the pic ;-)
