Atoll AM80se Power Amplifier

The Atoll AM80 SE amplifier is a power amplifier with a capacity of 80W per channel. The production quality of this amp is second to none, with an 8mm-thick aluminium front panel and a 1.5mm-thick metal body. It is a rigid machine that knows how to ward off all mechanical vibration. The top of the amplifier is perforated for increased heat ventilation. It has a stereo RCA input for connecting to a preamplifier (e.g. Atoll PR100 SE preamplifier or Atoll PR200 SE preamplifier) or integrated amplifier with a preamp output (e.g. any product in the Atoll IN SE2 integrated amplifier range). If you connect the Atoll AM80 SE power amplifier to an integrated amplifier, it will take on the functionality of a preamp. The preamplifiers and integrated amplifiers in the Atoll IN SE range all feature a dual preamp output. This gives you the option of bi-amplification using 2 AM80 SE power amps, as this model can be bridged to create a monoblock amp. Bi-amplification means that each speaker is powered individually (1 amp per speaker). To bridge the Atoll AM50 SE amplifier into a monoblock amp, all you need to do is flick a switch located inside the device.

The toroidal transformer can reach up to 330VA, for a total capacitance of 30,000 µF. To prevent vibration, resin has been applied to the screws holding the transformer in place. The Atoll AM50 SE power amplifier also offers the function of a timer system for switching it on. A protective relay for the speakers and amplifier output stages (to protect against overcurrent) is activated a few seconds after it is switched on. 

This power amplifier has all of Atoll’s trademark exceptional neutrality. The dynamic range is bright without being brash or overstated. It delivers excellent balance across all registers, from the bass all the way up to the treble. The midrange is precise, without a hint of brashness or artificial emphasis.
