Gain and Loading

It is recommended that the loading not be changed from 50 kwhen using a moving-magnet cartridge.

The gain of the phono stage is set at the factory to 50 dB, which is well suited to most modern phono cartridges. In addition, the gain is adjustable in 10 dB steps from 40 dB to 60 dB, accommodating virtually any cartridge made.

Recommended gain settings are as follows:

Cartridge Output

Phono Gain

Gain Resistor

Less than 1.0 mV . .

. . . 60 dB . . . . . . . 10

1.0 mV to 3.0 mV .

. . .

50 dB . . . . . . . 75

Greater than 3.0 mV

. . .

40 dB . . . . . . 249

These are guidelines only. Variations from these settings are perfectly acceptable.

The default cartridge load is 50 k, which is suitable for almost all cartridges. However, many moving-coil cartridges yield better performance if they are loaded with a lower impedance.

Usually, a lower load impedance results in a more focused soundstage, with greater image solidity and less apparent distortion. A higher load impedance will give a more open sound, with greater “air” and “life”. The final value must be chosen by ear to give the best sound in your particular system.
