Page 8: Internal Settings
Internal Settings There are four (4) types of input settings available on the MOON 310LP Phono Preamplifier; Capacitance loading, Resistance loading, Equalization curve and Gain level. Each setting is adjustable through the use of jumpers. For each type of setting, there are 2 banks of jumpers –... - Page 9 Equalization Curve: The MOON 310LP Phono Preamplifier is equipped with circuitry for two (2) different equalization curves; The RIAA standard and the less common IEC modified curve. The main difference is that the RIAA curve produces a flat frequency response from 20Hz to 20kHz;...
- Page 10 Gain Setting: There are four (4) gain settings available on the MOON 310LP. They are 40dB for MM cartridges and 54dB, 60dB and 66dB for MC cartridges. However, keep in mind that when using the balanced XLR outputs, each of these gain levels increase by a factor of 6dB to 46dB, 60dB, 66dB and 72dB respectively (note: to keep the circuit board labelling simple, only the single- ended RCA gain levels are indicated).
