1. Basic information about the C6m

The case is made of magnetic shielding steel and aluminum. The audio-connectors are all gold plated to

minimize electrical losses and provide long lasting perfect contacts.

A switch mode power supply delivers clean, hum-free electrical energy for the digital and analogue sections

of D/A-converter and the preamplifier. All voltages are additionally buffered by large capacitors directly in the

circuitry where they are needed.

The power amplifier has a separate power supply with a powerful toroidal transformer. This guarantees that

independently of the demanded output power the power amplifier has no influence on the preamp or the

D/A-converter.

1.3 Preamplifier section

The input circuits act extremely fast and use special semiconductors for exact and nearly noise free sound

reproduction. SMD technique allows a very compact circuit layout and thus extremely short signal paths.

The volume control is done by highly precise integrated circuits. They allow setting in 0,5 dB steps and their

channel balance is better than 0,05 dB. All this provides an absolutely precise, musical sound reproduction

from lowest to highest listening levels.

If You whish to correct the frequency response at low listening levels or to have more or less treble or bass,

You can activate the sound processor and set the frequency response. For linear reproduction the whole

circuitry is removed out of the signal path by relays and has absolutely no influence.

The power amplifier is built on a pc-board with double thick copper coating. The short signal paths allow high

damping factors in order to achieve optimal speed and speaker control.

Protection circuitry against overheat and short circuit is on board to protect Your equipment in an optimal

way.

The power amplifier of the inspiration C6m uses two output stages and two power supplies. One output

stage is working from a low voltage supply when only low power is demanded. During this time the other

output stage is also working, but doesn't deliver current to the speaker (and therefore produces no heat).

When the output power increases (for example when a drum is beaten), the second output stage with it's

high voltage supply is activated without delay and delivers high peak power to the speakers. In a music

signal peak power is only demanded for a short period of time. Thus the power amplifier of the inspiration

C6m works in a very efficient way and produces no unnecessary heat.

Of much more importance is the advantage in musical reproduction: the output stage for small signals acts

extremely quick and nearly noise free. So it can unveil the finest details of the music signal. The much more

powerful second output stage delivers the current only for dynamic peaks. These are very important for

realistic reproduction of music, but make only a very small part of the music signal. So this output stage stays

cool and therefore reproduces a fresh and clear dynamic music at any time without ever sounding stressed.
