About the FM 155-MKII R
The FM Acoustics FM 155-MKII R is a compact Resolution Series line-stage preamplifier with an external FM 105 power supply. Its fully single-ended signal path is designed for high-purity line-level operation, while suitable P.I.T. cables allow connection to pseudo-balanced or true-balanced equipment. The “R” designation denotes remote-controlled motorized volume adjustment. FM Acoustics describes the model as retaining the established 155-series design while incorporating refinements developed for its larger Resolution Series line stages.
