Line Magnetic LM-217IA

Line Magnetic LM-217IA


Single-End Tube Amplifier

The Line Magnetic 217IA integrated amplifier operates in Class A with tubes 300B mounted in “Single-ended” and delivers a power of 2x8W. It has 3 unbalanced line inputs, a CD input and groups of 4 and 8Ω outputs. The backlit level meter on the front is used to adjust the polarization of the tubes. The use of high quality components (Realcap capacitors, potentiometer ALPS) wired in the air for the most part is the guarantee of exemplary reliability. Its output transformers are EI type designed especially for it allow to manage a very wide range of speakers. The LM-217IA delivers sound that is dynamic, rich and natural. Voice soft modes and Pure and smooth are suitable for vocals and softer music based of ropes.
