Sujet [News] Telefunken USA R-F-T M16

Citation : R-F-T M16 MkII offers superior sonic performance and mechanical design, while boasting a unqiue voice of its own somewhere between a C12 or U67. The circuit design is based around a custom wound transformer from AMI / TAB Funkenwerk and a GE JAN 6072a tube.

Citation : THE APEX 460 IS VERY REMINISCENT OF THE REVERED AKG C12 & ELAM 251. LIKE THE AKG C12 & TELEFUNKEN U47 THE APEX USES A TRIODE TUBE PREAMPLIFIER WITH THE TUBE AND TRANSFORMER MOUNTED UP INSIDE THE MICROPHONE BODY. THE GOLD 6 MICRON COATED DUAL DIAPHRAGMS OF THE 460 ARE ATTACHED IN A SIMILAR MANNER TO THOSE CAPSULES USED IN THE VENERABLE U67 AND C12 TUBE STUDIO MICROPHONES. THE TUBE AND CAPSULE ARE BOTH SECURED IN ANTI-VIBRATION MOUNTS AND AN EXTERNAL SHOCKMOUNT IS ALSO PROVIDED LEAVING THE 460 NEARLY IMPERVIOUS TO VIBRATIONAL NOISE.


THE WORKMANSHIP AND SOUND IS VERY IMPRESSIVE FOR SUCH AN ECONOMICAL PRICED MICROPHONE. THE APEX 460'S DUAL DIAPHRAGMS HAVE A WORKING DIAMETERS MEASURING 1" or 25mm AS OPPOSED TO THE 19MM OF DIAPHRAGMS USED IN OTHER ECONOMICAL "LARGE" DIAPHRAGM CONDENSER MICROPHONES CURRENTLY ON THE MARKET.

THE DUAL DIAPHRAGMS ARE POWERED EXACTLY LIKE THOSE IN THE VENERABLE AKG C12 AND AKG "THE TUBE" MICROPHONE...THEN COUPLED INTO A VERY SIMILAR CLASS "A" TRIODE PREAMPLIFIER CIRCUIT.

THE SECOND HALF THE DUAL TRIODE TUBE IS NOT USED IN THE ORIGINAL AKG C12 MICROPHONE CIRCUIT DESIGN AS THE ORIGINAL IO'S IN THIS SECTION OF THE TUBE ARE SIMPLY DISABLED. HOWEVER, IN THE APEX DESIGN THE 2ND HALF OF THE TUBE IS UTILIZED AS A CATHODE FOLLOWER.

THE UTILIZATION OF THE CLASSIC CATHODE FOLLOWER CIRCUIT DOES NOT INCREASE THE OUTPUT LEVEL. HOWEVER, TAKING THE OUTPUT FROM THE CATHODE REDUCES THE OUTPUT IMPEDANCE BY ABOUT 20 TIMES. NOW A LOWER TURNS RATIO, OUTPUT TRANSFORMER CAN BE INSTALLED PRODUCING A LARGER OUTPUT LEVEL WITH A VERY GOOD SIGNAL/NOISE RATIO.

Citation : These are the preliminary results of a microphone shootout at The Factory studios here in Vancouver with a APEX 460 multi-pattern tube microphone used on vocals and acoustic guitar.

The Factory Studios is the old "Little Mountain Sound" where A/C D/C, Aerosmith, Bryan Adams, David Lee Roth, Mettalica and others have all recorded in Vancouver.

The 460 was compared with a Telefunken U47, Akg C12, Neumann tube 149 and a couple of very expensive BLUE microphones. The gain of the microphones were matched through 6 Neve 1081 modules with no EQ or filtering used. 15 out of 15 average listeners(not professional recording engineers) picked the 460 as a favourite on female vocals while other microphones got 3 to 5 votes and 50% of the same listeners also picked the 460 as a favourite on male vocals. It also favoured very well on the acoustic guitar compared with the other microphones. One or two experienced recording engineers describe the 460's sound as having the response curve of a finished vocal. This coloured response might not be practical for all applications but it will give the home recordist a leg up toward great vocal sounds.

Hors sujet : Et félicitations pour les S3, c'est vraiment somptueux (et je pèse mes mots) comme monitoring...

Citation : (de tout façon sm58 et 460 rien à voir rien de rien)
