Preamplifier and high-to-low impedance converter


Rating: 0.00 / 10 
Preamplifier Circuits / Audio Circuits

Thiscircuit matches the very high impedance of ceramic cartridges, unity gain, and low impedance output. By `loading` the cartridge with a 2M2 input resistance, the cartridge characteristics are such as to quite closely compensate for the RIAA recording curve.
