TR 14

Vacuum Tube Ribbon

When designing the R 14, TR 14 and SR 14 microphones we wanted to create a classic vintage-style ribbon microphone in the vein of the early RCA microphones.
We used classic long ribbon geometry. Thin corrugated aluminum ribbon is tensioned between two rare earth neodymium magnets. As the ribbon moves with the ambient acoustic air pressure variation a current is induced in the ribbon itself. This current is the microphone's output signal. The ribbon is placed just forward of the magnet center. This provides a very slight low-end roll-off on the backside of the microphone, which can be very useful if proximity effect needs to be countered. To handle low-level sources and long cable runs transparently we added a tube gain stage in the Peluso TR 14 Tube Ribbon Microphone. The TR 14 delivers clean balanced output through the use of a custom output transformer. Sonically the TR 14 delivers added harmonic complexity from the tube to the rich, warm, and silky smooth sound and generous low end of a ribbon microphone. It is un-hyped, natural, and takes EQ very nicely. The TR 14 ribbon microphone is the perfect complement to the condensers in your microphone collection.

      "This thing sounds great on electric guitar!  I used it on over driven guitar with a classic ’65 Fender Deluxe Reverb and my old Strat. I placed the mic in a variety of places, but preferring it, in this case, about 2 inches in front of the grill.  It turned out a big sweet sound. I had to boost the EQ about 3 db at 3.5K, which is pretty standard for me to get the sound I like with ribbons and this guitar. There was less proximity effect than with the R-14, but it was just a great sound. And then I used it on my Gibson ES-355 and a Seymore Duncan Convertible for some fantastic crunchy guitar.  It’s the best sound yet I’ve had with that combination,  -- and I’ve been that guitar/amp combo for probably 20 years or more!"
      "I’ve used this a few times on horns: two sessions with a jazz trumpet player and twice with a great alto player playing some funky stuff.  This is the mic."
      -Henry Robinett, TapeOp
