Page 8: Internal Settings
MOON 310LP Phono Preamplifier 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 MOON 310LP Phono Preamplifier Internal Settings (cont’d) Capacitance Loading: There are three (3) different settings available for setting the capacitive load; 0pF, 100pF and 470pF which are represented by jumper sockets J6, J7 and J8 respectively for the left channel and jumper sockets J24, J25 and J26 for the right channel (refer figure 4 below).
- Page 10 MOON 310LP Phono Preamplifier Internal Settings (cont’d) 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).
