DESCRIPTION

The Coda Continuum Ts amplier is designed with the same level of thoroughness

usually reserved for the nest amplier gain stages. Balanced interconnections are

provided to take advantage of their greater noise rejection they provide. Dierential

voltage gain throughout provides exceptional rejection of external noise and contrib-

utes to the inherent DC stability of the circuit. This allows direct coupling at the

Balanced Inputs without servo circuitry. The unit also uses output followers operating

without feedback.

The front end is designed to provide a slew rate of 50 V/us without entering Class B

operation as is common in many other designs. This combined with excellent high

frequency design insures linear operation at high speed. The supplies take a very

direct approach to high performance. A top quality 2000VA toroidal transformer with

independant rectiers and about 80,000 uf of total capacitance with very low ESR

and inductance are used.

The current stage is capable of producing currents in excess of 100 peak Amperes

with a degree of linearity and speed which is not matched by other designs when

producing only a fraction of of this current. This is achieved by the implementation of

several distinct circuit features.

Each channel uses 20 individual output transistors with a combined power capability

of 3600 Watts and 75 Amps with a bandwidth of 10 Mhz.

The bias section is designed to produce a precision transition with no abrupt changes

in distortion or output impedance. This “Precision Bias” technique yields seamless

performance regardless of the complexity of the load impedance. With such linearity

and bandwidth, no overall feedback correction is used. One advantage of this is a

high degree of immunity from interactions with complex speaker loads or cables.
