8. rcuits We have incorporated several advanced and highly effective protection circuits in the output stage in order to protect your amplifier and the connected speakers from abuse and faults Heat current and DC are under constant surveillance by a microprocessor which will shut down the amplifier if the accepted values are exceeded Components Every single component in the PWR 222 must live up to not only stringent production tolerances and over specified values but equally importantly it will not be selected before having been approved for its sonic capabilities through many intensive listening tests Simply put if it does not sound right inside its circuitry environment we cannot use it regardless of how good its measurement values are This is the only way to maintain a natural crisp and clear soundstage Most of the components are only working at 3096 of their maximum workload capacity under normal use This will ensure your amplifier a long life with a minimum of stress Fine Tuning by Listening The last 596 of fine tuning and voicing is by far the most complicated and time consuming part of our development work Single critical components are replaced and often voltage and current supplies need to be modified to accommodate them and consequently listening starts all over again In addition blind test listening is used not just using our own reference system but also in other setups as measures we have taken to complete this amplifi
