[QUOTE="Shonver, post: 1117501, member: 34"] ELECTROCOMPANIET EC 4.7 Av = 0dB = x 1 Mark Levinson 38S Av = 18.9dB = x 8.81 Krell Industries KRC-HR = 6dB = x 2 The high output voltages quoted refer to the circuit's maximum output capability, not its normal operating output voltage. For instance, the ELECTROCOMPANIET EC 4.7, with its x1 gain would require an input voltage of 8V in order to output its claimed 8V (">8V") level. But it would drive 2V max if the input signal is 2V.
