PHS 7.3 dual-mono

The PHS 7.2 and PHS 7.3 are dual-mono phono preamplifiers, featuring JMF Audio’s unique ALP and ALP-EM linearization technologies. These phono preamplifiers can handle up to 2 (PHS 7.2) or 3 (PHS 7.3) tone-arms or record players. Their advanced hand-calibrated balanced input stage and high gain take full advantage of low-level moving coil cartridges, without the need for step-up transformers. The innovative input module interfaces provide 16 resistive and 16 capacitive loads for each input and corresponding cartridge, for precise dampening and tuning of the upper range of frequencies to achieve a linear overall response. The load settings are assigned to each input which allows seamless switching from one tone-arm to another. The record collector oriented PHS 7.3 features a special mono mode and three optimized alternative compensation curves for the enjoyment of pre-RIAA era recordings.

The PHS 7.2 and PHS 7.3 were developed as instruments for the music and inherit from JMF Audio’s decades of know-how and the relentless work of its research and development department. Starting from a blank sheet of paper, over three years of development were necessary for these products to see the light and reach the first customer; two more years than first planned… Music deserves all our attention.
