As a direct result of feedback from users of TFPRO equipment, the company have developed the P110, a new microphone amplifier/compressor combination that they say is for studio recording of real sounds.
TFPRO tell us that the P110 is a specialist single channel preamplifier, phase shifter, compressor and equaliser with advanced analogue features designed to be a perfect tool for voice recording and ‘tracking’ in the studio.
Here’s how they describe it in their own words…
The mic amp.
The microphone amplifier is, of course, transformer coupled using class-A ‘current mode’ multiple amplifiers, giving extreme signal handling capability and overload margin. But more important is the sound! The transformer input combined with amplifiers that are never swamped by transients produce a smoothness impossible with lesser equipment.
Variable phase
The phase shifter gives the option of switched polarity reverse in addition to 180 degree variable phase setting. This unusual feature come Mic amp/compressors into its own when multiple miking say a guitar amplifier; it is easy to adjust the phase of one of the microphones to either enhance the sound, or achieve cancellations.
The compressor
The compressor/limiter is of advanced optical design, retaining the warmth and drive of earlier TFPRO designs and adding versatility with ratios from a gentle 1.2 to 1, up to full extreme limit, and with switchable ‘models’ to provide a taste of other historic compressors, and add colour to the compressed sound. The ‘make-up’ amplifier is a discrete transistor class-A design retaining the smoothness of sound from the mic amp.
The equaliser
The use of equalisers in recording channels was at its peak in the late 1970s and early 1980s. The most popular types of EQ at that time were semi-parametric and this is the type used in the P110. The four frequency bands are musical and overlapping and the circuit is ideal for minor tonal correction of very high quality audio.
Metering
A VU meter provides audio ‘input’ metering (that is, showing the audio level immediately prior to the main output stage). This type of metering is most useful in a studio situation. The VU meter can be switched to read ‘gain reduction’ in the compressor. LEDs also show when there is audio signal present in the circuits, and when the output of the mic amp is approaching clipping.
Mechanical.
The 2U rack mounting case weighs around 2 kilos and is made of steel, with a substantial aluminium front panel. Power is mains, and can be 230V or 115VAC, voltage selection is at the rear fuse holder.
