PH-10 is an ultra-versatile phono preamplifier that offers unique features, including EQ CURVES, LOAD and GAIN adjustments: a fully analogue design engineered exclusively with high quality coils, capacitors and resistors. PH-10 is controlled via knob and display using a sophisticated micro-controller to select the functions through our custom firmware that is loaded on a micro SD dedicated flash memory and can be updated easily via PC. The micro-controller is separated and independent from the audio signal path to guarantee always clear and pure sound. Once the tonearms are connected, PH-10 can be set with 4 different GAIN levels [-3dB, 0dB, +3dB, 6dB] to match precisely the output level of any MM or MC cartridge. The perfect setup is guaranteed with 9 different LOAD options [10Ω, 22Ω, 47Ω, 100Ω, 220Ω, 470Ω, 1000Ω, 22KΩ, 47KΩ] that will let you adjust the preamp to match it with a large number of cartridges in a q easy way.quick,
