DISPLAY
In normal operation, the level setting is displayed and various indicator lights will be
illuminated. When the display button is pressed, all lights will extinguish. Pressing any
button will turn on the display and indicator lights for 5 seconds, and then extinguish.
The only exception is standby, which will always have the standby light illuminated.
Pressing the display button while the display is off, or during the 5 second timeout
period, will turn on the display and normal operation will return.
GAIN ADJUSTMENT
Pressing the gain button will show the gain for the phono section. Press the right side of
the display glass to increase the gain, and the left side of the glass to decrease the gain.
The gain displayed is in dB and is the gain attained when the unit is new with factory
supplied tubes. A unit with aged tubes, or non-factory tubes (shame on you!), may not
achieve these gain values.
It is possible for the phono section to overload the line section. Distortion on peaks is the
most obvious indication, but sometimes it can be a less obvious compression of dynamics
and an upper midrange hardness. Simply lowering the gain of the phono section will
eliminate this problem. The selected gain is stored in non-volatile memory and will
therefore not be lost even if the power is disconnected.
The mute button is active while in the gain adjustment mode.
The below chart shows the recommended gain settings by cartridge output level. These
recommendations will produce the best signal-to-noise ratio and lowest distortion. It is
advised to try one setting above and below the recommended value to determine the best
setting for your system.
Cartridge output level (millivolts)
Recommended Gain Setting
Less than .2 75dB
.2 - .5 62dB
.6 - 1 56dB
1.1 - 2 50dB
2.1 - 5 44dB
5.1 - 7 38dB
LOADING ADJUSTMENT
Pressing the load button will show the loading for the phono section. Press the right side
of the display glass to decrease the loading (increased ohms), and the left side of the glass
to increase it (decreased ohms). The loading displayed is in ohms, and an H on the
display indicates kilo ohms.
