The amplifiers are mostly cloud amps (Cloud Electronics Ltd 140 Staniforth Road Sheffield Yorkshire S9 3HF, UK) http://www.cloud.co.uk/ these are very high quality amplifiers there old range GS & CS250 ranger really nice I have change the output driver stage transistors for a hire wattage rating and increased the capacitors on the power supply. Then I put a small power supply to run on top of the main supply which incorporates two rectifying diodes to feeds the main supply. The Cloud CS amplifier is class B push pull but the crossover distortion in very small. Doing this changer to the amps is like putting a turbo charger and nitrous oxide kit on a car. My DJ mixer in a Cloud 600 with the graphic equalizer unit built in its case.
Next in line is Behringer studio denoiser single ended noise reduction NR system this just gets rid of the hissing sound to give the finest sound quality to your musical performance. The Behringer denoiser is one of the older models but it dose what I want it to do. Next is a BBE Sonic Maximizer this gives a High Definition Sound with full range and rich bass response bass boosting putting a natural clarity to the performance it give the records live sound effects. You can clearly tell when you switch this unit in and out. This then feeds into the Cloud 3 way active crossover. Audio crossovers serve the purpose of splitting the audio signal into there own separate frequencies bass woofers 400Hz midrange 2000 Hz and the higher frequencies which go to there own individual amplifiers amplifying there different frequency ranges. Doing this will give about +3Db of gain. For this part, six sound amplifiers are needed. The sound should be divided for the wattage 60% bass 30% midrange and only 10% for the top end frequencies.
