The HZA4-70 is a four-channel amplifier with direct 100 V line (high impedance) outputs. 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 ones the audio quality improvement (specially in the low-end frequencies) and the convection cooling, 100% silent.
