Atoll IN50 Signature

The IN50 Signature is the entry model in Atoll Electronique's integrated range, built in France around a single push-pull MOSFET output stage running in class A/B. It uses a 170 VA toroidal transformer and an ALPS motorized volume control.

Atoll offers optional DAC and phono boards for the line, fitted to the AUX input. A remote is optional.
