MOON i 3.3 Integrated Amplifier

Optional Phono Section (Cont’d)

Internal Settings

There are three (3) types of settings available on the optional phono section of the MOON i 3.3 Preamplifier; Capacitance loading, Resistance loading, and Gain level. Each setting is adjustable through the use of jumpers. For each type of setting, there are 2 banks of jumpers – one each for the left and right channels. This is the result of the phono section’s genuine mirror-image circuit design which yields exceptional stereo separation.

Always disconnect all audio connections and the AC power cord of your MOON i 3.3 Preamplifier prior to changing any of the following input settings.

There are a total of six (6) screws, located on the top of the chassis, that you must remove using the included allen-key. Once these screws are removed, carefully lift off the chassis cover. Once the cover is removed, you are ready to make all of the necessary internal adjustments to the i 3.3 phono module to achieve optimal sonic performance.

Resistance Loading:

There are two (2) different settings available for setting the resistive load; 100Ω and 47kΩ which are represented by jumper sockets R9 for the left channel and jumper socket R24 for the right channel (refer to figure 2 – section labeled “LOADING”). The factory default setting is 47kΩ, therefore both jumpers will be found in each of the two left most sockets.

In the event that you’re using a moving magnet (MM) cartridge, it is recommended that you leave the jumpers inserted in the factory default setting of 47kΩ. Conversely, if you’re using a moving coil (MC) cartridge, you should use the 100Ω jumper settings by simply inserting the supplied jumpers into each of the two right-most sockets of jumpers R9 and R24.

Capacitance Loading:

There are two (2) different settings available for the capacitive load; 0pF and 100pF which are represented by jumper sockets C9 for the left channel and jumper sockets C17 for the right channel (refer to figure 2 – section labeled “LOADING”). The factory default setting is 100pF for a moving magnet cartridge, therefore both jumpers will be found in each of the two right most sockets.

In the event that you’re using a MM cartridge, it is recommended that you leave the jumpers inserted in the factory default setting of 100pF. Conversely, if you’re using a MC cartridge, you should use the 0pF jumper settings by simply inserting the supplied jumpers into each of the two left-most sockets of jumpers C9 and C17.

Gain Level:

There are two (2) different settings available for gain level. They are 40dB for MM cartridges and 60dB for MC cartridges, which are represented by jumper socket J17 for the left channel and jumper socket J22 for the right channel (refer to figure 2

–section labeled “GAIN”). The factory default setting is for a MM cartridge , therefore both jumpers will be found in each of the two right most sockets labeled MM; It is highly recommended that you do not use the jumpers labeled MC for an MM cartridge as this will overload the preamplifier. In the event that you’re using a MC cartridge, you should insert the supplied jumpers into each of the two left-most sockets labeled MC.
