INTRODUCTION

This amplier is a precision device, designed in an eort to provide the listener with
unmatched sound quality, design, and construction. In order to operate your amplier
properly and to realize all of the capabilites of the CONTINUUM Tm, we recommend
that you read this entire manual carefully.

DESCRIPTION 3

The Coda Continuum Tm 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 contrib­utes 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.
