Hi,
Could someone please let me know the amplifier gain for C-Audio SR707 & SR404, I have spent ages trawling the web to no avail. Cheers.

Input Impedance = 10K.
Sensitivity = +4db. This applies to all ranges of SR amps. |

Hi, I am sure the gain works out at about 47 if my memory is correct.

Simon is that +4dBU? (1.2V)
That would make the voltage gain around 34 no?

Looking at the circuit, the two feedback resistors for each channel are 47k & 1k, which sets the gain at 47 (approx). The spec says it's +4db (1.23 volts), so i assume there may be a small amount of tolerence.
