Octave Phono Module Preamplifier

Tube based external phono preamplifiers are the preference of music lovers who prefer the sonic virtues of analogue reproduction. Modern MC (moving coil) pickup systems, with their low output signal, cannot be connected to a tube based phono stage without an additional step up transformer to keep the total noise to an acceptable level.When OCTAVE was founded, Andreas Hofmann began developing phonostage preamplifiers with an electronic MC input, because transformers are very sensitive to magnetic stray fields and they are limited in respect of the load impedance and the amplification factor. The OCTAVE Phono Module is a full feature phone preamplifier which allows the use of three different Input modules and three different Output modules.The three Input modules can be used simultaneously. An single-ended (RCA) MM (moving magnet) module, with switchable Input Impedance 1k Ohm and 47k Ohm. An single-ended (RCA) MC module featuring switchable Input Impedance between 50 to 1k Ohm, with Gai
