Notes: Single-channel version of the classic Phoenix compressor with mic-gain boost, active EQ (Presence/Air), and 'variable mu' style compression — the manufacturer itself calls it 'about the nearest we'll ever get to a conventional channel strip,' so device_class is a judgment call following brief guidance ('compressor = Compressor/Limiter') even though it also functions as a mic preamp + EQ. Max gain: Mic 52dB / Pad 38dB / Line 25dB; MOL +25.5dBu into 10kΩ; THD 0.12%(1kHz)/0.22%(100Hz); S/N 96dB; Net weight 4kg (from official spec PDF).
