QC Twenty Four P
QC Twenty Four P
With the analogue purist in mind the Twenty Four P has a moving magnet / moving coil toggle switch and direct / variable level control over volumes for use with all kinds of amplification. Unlike the power amplifiers, the QUAD pre amplifiers utilise a completely new design. Together with transformers designed by one of the world’s leading authorities and relay input switching the musical signal is preserved in its purest form – pursuant to the philosophy of the theoretical perfect amplifier which as Peter Walker himself stated, is ‘a straight wire with gain’.
