Each Channel of the MA 6S includes an input Voltage Controlled Attenuator (VCA). This carefully designed VCA prevents clipping at the output of the amplifier for any load for up to 15 dB of input overdrive. This VCA provides additional headroom to each Channel, making the 100 watt ratings effectively much higher, and the results much louder.
All Channels of the MA 6S are completely independent. Each is contained on its own circuit board making it immune to the actions of any other Channel. Power is distributed to each Channel from one master high current power supply, designed so that signal may not back-feed from a heavily loaded Channel to any other Channel. This makes power supply cross talk between Channels inaudible.
The optional KTM 6 allows rackmounting of up to six output transformers. Individual 70.7 V and 100V transformers are also available.
