High Impedance Mono Amplifier

ECLER HSA300 is a single channel amplifier with direct 100 V line (high impedance) output. It’s equipped with ECLER’s proprietary SPM 100 Technology - Channel N, which allows for 100 V speaker lines connection without using 100 V line transformers, as this kind of amplifiers usually do. This fact has many advantages, being the main one the excellent audio quality, specially improved in the low-end frequencies when compared to classical 100V line amplifiers.
