Gain
Gain for the RCA outputs (RCA) can be set to 60, 50 or 40dB. Gain will be 6dB higer, using the XLR outputs
(XLR).

To find out which type your cartridge is, please consult the literature accompanying your cartridge.
The literature for cartridges should also specify the correct input impedance (low-output MC
cartridges) and the correct input capacitance (high-output MC and MM cartridges), into which the
cartridge is designed to work. If in doubt please consult your dealer.
