Honey,
I Shrunk the Power Supply
Analog Audio in a Low-Voltage, Single-Supply World
Moore’s
Law ushered in an era of enormous digital signal processing power as
semiconductor geometries shrank to sub-micron levels. But with this
came shrinking power supplies. This seminar will show designers how to
operate conventional high-voltage dual-supply analog audio ICs from
single-voltage supplies. We will explore active and passive
rail-splitting, minimum required supply voltages, gain structure, and
optimal input/output termination.

The
Ins and Outs of Ins and Outs
Optimizing Performance of Balanced Audio Interfaces
A
presentation team, including the designer of THAT Corporation’s
balanced input stage product line, will dissect, analyze and
deconstruct the ubiquitous balanced audio interface. We will show how
to optimize dynamic range, input impedance, and common mode rejection
in balanced line inputs. We will explore optimized balanced output
circuits capable of driving loads in a hostile world. The team will
listen to examples as well as explore waveforms using instrumentation.

Mic
Preamplifier Alchemy
Demystifying One of Audio’s Most Misunderstood Circuits
The
mic preamp is one of the most difficult audio functions to implement.
Conceptually, it’s just a simple gain stage -- how hard can that be?
It’s tough to keep noise low under all conditions and still protect
the preamp from phantom power faults. And then you have to control
gain remotely! This seminar explores techniques for implementing
magical mic preamps using THAT Corporation’s best-of-class IC
solutions.
Presenters:
Les Tyler, Bob Moses, Fred Floru, Rosalfonso Bortoni
