The TDC happened because I wanted to re-visit the thinking behind my original 'Brick' using some new technology......

In the 21st century many functions are best left to the digital work station or the digital mixer, but there are still areas where analogue rules........

This microphone amplifier could be called 'old-fashioned', it's transformer coupled; it's warm and smooth yet precise and supremely accurate. It combines the very best of 'old guard' with original design that uniquely eliminates noise and harmonic distortions; it's using what I call a 'Kirchoff' amplifier, a circuit that uniquely gives extended low frequency response without the usual phase distortions, as well as a clean, transparent 'top-end' that just glitters.

The compressor is my optical design that naturally mimics the dynamics of the human ear so that it sounds 'natural' when applied to both the human voice and classical musical instruments.  Because of the compression shape it retains brightness even under heavy compression.

The harmonic enhancer is there to add (or subtract) harmonic overtones in a sensitive way that cannot be reproduced with digital plug-ins.

Metering is with a modified VU meter with an extended scale.... even in this digital world it's easier and less tiring to read real 'moving needles'!

 Quality does not have to be ruinously expensive! There are many very fine microphones available at amazing prices…. But when used with modern equipment it’s often like looking at a reflection in a dirty mirror.  The TDC gives a voice sound the best possible start.

Listening tests in the studio have been a resounding success in direct comparison with some of the most exotic and expensive mic amps in the world.

So the new 'TDC' (Ted's Definitive Channel) is designed, built and available from mid July….. ready to drive your personal favourite digital converter, and with a second analogue output for direct monitoring.

The new 'TDC' is being hand built in the UK (not more than 70 miles from London!) substantially and beautifully made by enthusiasts who appreciate good workmanship. 


   And the 16X happened because I needed lots of very good mic amps!


 The 16x is 16 transformer input individual microphone/line preamplifiers with headphone monitoring.

Each input has:-

  • XLR mic or line input via transformer,
  • Modular construction with individual channel modules.
  • Variable mic amplifier gain from ‘off’ to 65dB.
  • LED 4-segment per channel audio metering.
  • Individual switchable 48V phantom power on each channel,
  • Individual switchable high pass filter on each channel,
  • Individual solo button (for headphone monitoring) on each channel,
  • Individual TRS balanced line output on each channel,
  • Combined mono output.
  • Separate digital low-noise power supply.


The TFPRO 16x is a 2U rack mounted unit with 16 microphone/line inputs and 18 outputs.

The transformer inputs use advanced circuitry which eliminates noise and distortion effects from long cable runs.

The purpose of the 16x is to control and monitor large numbers of audio inputs for recording or listening purposes.

Each individual microphone input can be controlled for volume level and can be monitored on headphones via a standard headphone socket on the rear of the 16X. The ‘Solo’ function can listen to individual channels or any combination of channels.

Inputs to the unit are via XLR, outputs are via TRS 1/4 inch jacks. All connectors are on the rear of the unit.


   But after all that..... there are still compressors!!

P38EX Stereo Mastering Compressor  is a stereo 'opto' compressor solidly made in the UK. It is still affordable by the smaller studio, but with full mastering performance instantly recognisable as superior to any regular compressors...... and I do have a couple of new P38EX in stock now (Sept)....



The forums are full of comments and questions from engineers asking why their recordings don’t sound ‘right’ when they are following the directions and using the right gear. Why does an apple pie from a supermarket not taste anything like as good as one that grandmother made? The answers are remarkably similar! The supermarket pie has ‘uniformity’ processed into it; the ingredients may be pure and wholesome, but they are bland and ‘safe’. There are additives to preserve and packaging to enhance, the final result is pale and uninteresting. Digital equipment is designed by engineers who firmly believe that the ‘quality’ of a sound can be defined and measured, but great engineers know that there is much more to sound than that!

The TFPRO P38 range…., definitive optical compressors; compressors that brings out mood and feeling. The TFPRO P9….. Ted’s definitive equaliser; it brings warmth and life. The TFPRO M16….. Fine mic amps and mixing, a formidable combination; redesigned 16X version  now available.NOTE, this website is now much more a 'resource' than a sales window.  Ted still manufactures the odd compressor for those who insist! The range of TFPRO equipment was the result of a new look at the performance and design requirements of the 21st century record producer; a way of using the great tools and techniques of the past, and maintain the standards that are essential today. The range carries on and now extends with a new generation of Orbitsound labelled professional hardware starting with the microphone channel... the TDC.
