Summary
|
The
SSA-1.1 is a scaled down version of the MA2.2 where the power
supply design and chassis construction has been simplified.
The Class A mic input modules provide a high performance interface
to all microphone types. The cost savings by using integrated
circuits for the output functions have enabled us to provide
extra features such as the instrument input. The sonic difference
between the MA and SSA is quite subtle, but it is there if you
listen hard enough. |
The
MA-2.2 is a "no holds barred" design where attention
to every detail results in superlative sonic performance and
clarity. A simple signal path, low noise discrete power supply
regulators and the True Class A discrete amplifier modules are
carefully integrated to provide excellent measured specification
and high speed amplification, even at high gain settings. The
rugged chassis design ensures continued service even in demanding
mobile situations. |
