Every 6dB of gain equates to a doubling of voltage; as such, a hypothetical amplifier with a voltage gain of 30dB will increase voltage by 2^5, or by a factor of 32. For unbalanced inputs, the THX standard gain level is 29dB; utilizing balanced inputs decreases this to 23dB, though naturally the output of the preamp is boosted by 6dB under this scenario (i.e. …

Instead, PS Audio calls the GCC-100 and its sisters, the GCC-250 and the GCC-500, Control Amplifiers or Variable Gain Power Amplifiers. Unlike a standard integrated amplifier, the GCC-100 has no volume control in the traditional sense; ie, no potentiometer or resistor ladder that shunts part of the signal through ground. Instead, the gain is varied directly by a …
