New Roll Music Systems 'Tubule' Now At KMR Audio

Audio consultancy and equipment supplier KMR Audio Ltd have announced the availability of the new RMS5A7 tube microphone preamplifier or 'Tubule' in 500-series modular format from Roll Music Systems.
Roll Music Systems, manufacturer of the popular RMS216 Folcrom passive summing device and the acclaimed RMS755 Super Stereo compressor, have worked to satisfy user requests for a tube-based module.
Justin Ulysses Morse (Mr Roll Music) said: "These requests have been met almost universally with claims by designers and engineers that it couldn't be done. With the new Tubule, Roll Music Systems has proven it can be done, and be done well!"
The Tubule is a real transformer-coupled tube mike preamp, getting all its amplification from a standard dual triode tube. It uses sophisticated modern power management circuitry to generate the high-voltage plate supply and the high-current heater supply to power the tube. Careful design of this high-efficiency power management circuitry has allowed for a preamp that fits within the space and power consumption limitations of a single module.
The Tubule features switches for -20dB input pad, polarity inversion and phantom power, a 12-position gain control switch that ranges from 33 to 66dB in 3dB steps, and a continuously-variable input attenuator that ranges from 0 to -10dB for very accurate gain settings that can be easily recalled.
Established in 2003, KMR Audio provides service and guidance to the use and purchase of professional recording equipment. Further information is available at: www.kmraudio.com.
