SM Pro Audio TC02: Dual channel microphone preamp - Manual (Page 5)

5 Introduction - Design Concept
1. Introduction
In purchasing the new SM Pro Audio TC01/TC02, you have acquired a tube microphone pre-
amplifier channel strip of high class that meets many of the demands of the home/pro studio.
For your reference in this manual, the TC01 and TC02 units are either single or dual channel
designs of the same circuitry. The TC01 is the single channel unit that is half rack size, whereas
the TC02 is a dual channel unit, just like 2 x TC01’s side by side.
The market size for digital audio interfaces and computer based digital editing has increased in a
massive way. With systems available at very low prices, more and more users are utilizing this
technology. One of the main problems with many of these systems is the input stage only consist-
ing of unbalanced line inputs or very low (or no mic pre) gain structure for the balanced input stage
and the unavailability of Phantom power.
The TC01/TC02 comes to the rescue with either one or two channels (TC01 or TC02) of balanced
input with a tube microphone preamplifier, optical compression, Phantom power, phase reverse
switch, low cut, and for output volume for each channel. Both the TC01 or TC02 units can now
solve many of the connectivity issues which are raised in a large range of situations, whether in the
home or professional studio.
2. The Design Concept
2.1 High quality components and design
The philosophy behind SM ProAudio products guarantees a no-compromise circuit design and
employs the best choice of components. The components used in the TC01/TC02, are exceptional.
They boast extreme linearity and very low distortion characteristics. The tubes used are hand
selected and tested for optimum performance.
2.2 Inputs and outputs
All inputs and outputs are secured firmly to the exterior chassis housing. This ensures robust
quality and confidence in performance under all conditions.
