Phaedrus Audio are joining Pspatial Audio to collaborate in international marketing and sales of the Stereo Lab software family.
Originally a stereo-enhancement program, Stereo Lab has developed over several years and, now with the addition of equalisation and noise-reduction for all shellac-era records, Ambisonic decoding, 5.1 up-conversion and full implemention of loudness measurement and adjustment to ITU BS.1770-3, the software has value to mastering, broadcast and recording sound engineers as well as sound-archivists working with media which might range from phonograph cylinders, to analogue-cassette tape, to high-resolution digital files.
Telefunken EF14/ EF12 tubes have long been favourites for substitution for the VF14 device in mod's, clones and copies of the famous U47/U48 microphones.
Sadly, even these devices are now becoming scarce; at least, those with sufficient performance for use in a microphone.
The Phædrus Audio EF14M is designed as a drop-in replacement.
Phædrus Audio Groove Sleuth Adaptor preamplifiers convert the XLR socket microphone inputs on commercial computer sound cards to non-equalised phono cartridge inputs.
Phædrus Audio Groove Sleuth Adaptors ensure the phono cartridge and the microphone inputs are presented with the appropriate signal levels and impedances. The 48V phantom-power powers the miniature Groove Sleuth Adaptor preamplifiers.
Versions exist for converting moving-magnet and moving-coil cartridges to a standard microphone input and for converting Phædrus Audio PHLUX active phono cartridges to a standard microphone input.
Phædrus Audio SPIRIT SupertubeTM is designed to operate as a tube impedance converter in microphones supplied solely with 48V phantom power.
