MA 6S Multichannel Amplifier

MA 6S Multichannel Amplifier

The Rane Model MA 6S Multichannel Amplifier supplies six completely independent amplifier channels in one 3-space rack-mount unit. Each channel delivers 100 watts rms into an eight ohm load, or 150 watts each into a four ohm load. Adjacent pairs of channels (1&2, 3&4, 5&6) may operate bridged to provide 300 watts into an eight ohm load.

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, however the power supply is 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 heavy gauge all-steel construction of the MA 6S offers a high level of mechanical integrity, even when the amplifier is rack-mounted and unsupported in the rear. As an added benefit, mounting holes are provided on the side rails so the amplifier may be supported from the back.
