Introducing

SHHA Generation 2

Analog Line Modules

The SHHA Generation 2 Analog Line Modules

Just as the preamplifier is the essential heart of

the finest music systems, the SHHA line module is

the essential heart of our high resolution preamplifiers.

For this reason, the modular architecture of Spectral

preamps has been developed to accomodate design

evolution of our SHHA technology with convenience

and ease. Now the new SHHA G2 module takes

our wideband, fast-settling discrete circuitry

to a new level of performance and signal linearity.

Spectral engineers have continued to optimize the dense,

surface-mount fet topology of the SHHA module with new

components, materials and circuit refinements including:

Newly optimized layout and dialectrics provide

increased circuit speed and stability.

Hand-selected trim resistors replace trimmers

in critical signal path locations.

Improved heat dissipation provides greater

thermal stability and long product life.

These and other refinements in the SHHA G2 module

assure improved sonics and extended reliability in

all Spectral applications. Musical benefits include

greater low level detail and dynamic range.

The SHHA Generation 2 modules will be available in

DMC-15, DMC-30S and DMC-30SL preamplifiers

beginning in Fall 2003. SHHA G2 module sets will also

be available through our dealers for owners of Spectral

preamplifiers who are interested in upgrade services

beginning in early 2004.

In late 2000 Spectral introduced the new SHHA

analog amplifier technology. The 'Spectral High-speed

Hybrid Amplifier' module was a clean-sheet

reappraisal of state-of-the art analog circuit fundamentals.

This breakthrough signal technology debuted in the

DMC-30SL "Anniversary" preamplifier taking us a

significant step closer to realizing our ideal of the

ultimate preamplifier design.

Today the advanced SHHA technology is used in

all Spectral preamplifiers and has arguably

section performance of Spectral preamplifiers is

unmatched among high-end audio components with

SHHA modules achieving the fastest signal response

and the greatest voltage swing and current capability

in the industry.

Spectral's constant research effort to create the

finest possible preamplifiers has been an ongoing

quest since 1975. Possibly no other engineering team

has matched the depth of experience or develop-

mental history in high-speed analog audio design

achieved at Spectral. Constant engineering review and

design refinement have now made possible an improved

second generation SHHA module for Spectral

components.
