ACOUSTIC SOLID PHONO MM/MC

Dual-Mono phono preamplifier with active and passive RIIA equalization.

It stands out for its exceptional versatility, precisely adapting to a wide range of cartridges thanks to six separate dip switches for each channel. This configuration allows for fine adjustment of the gain, which can be set between 32 and 64 dB, optimizing the sound performance based on the characteristics of the cartridge used. For MC cartridges, the resistance can be adjusted from 47 kOhm to values between 50 and 680 Ohms in 10 Ohm increments, providing extremely detailed control of the load impedance. MM cartridge users also benefit from precise capacitive adjustment, allowing further adaptation of the system’s response to achieve a balanced and faithful sound.
