The gain is factory-set to 50
dB, which is well suited to
most modern phono cartridges.
The gain of the phono stage is adjustable in 10 dB steps
from 40 dB to 60 dB, accommodating virtually any
cartridge made. Recommended gain settings are as follows:
&DUWULGJH2XWSXW 3KRQR*DLQ *DLQ5HVLVWRU
Less than 1.0 mV . . . . . 60 dB . . . . . . 20Ω
1.0 mV to 3.0 mV . . . . 50 dB . . . . . . 150Ω
Greater than 3.0 mV . . . 40 dB . . . . . . 500Ω
These are guidelines only. Variations from these settings are
perfectly acceptable.
It is recommended that the
loading not be changed from
50 kΩ when using a
moving-magnet cartridge.
The default cartridge load is 50 kΩ, 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.
