buttons on the front panel, or the remote control. To select and store the gain for each input into
memory, proceed as follows:
Note: The Phono III comes with the gain memory set at 40dB for each input. If this is the desired gain
value for a specific input, no further action is required.
Ensure that the unit is operating in the Standby mode (LED not blinking) or the Mute mode. The
40dB gain LED will be illuminated.
Press the “A” input button and then press the button on the front panel, or remote control, for
the desired gain. This stores the desired gain in the memory for the “A” input.
Repeat the above process until all desired inputs have been assigned a gain value. If the default
gain value of 40dB is correct, the 40dB button does not need to be pressed since 40dB is already
stored in memory.
Table 1
provides guidance regarding the appropriate gain for various cartridge output levels. If you find
that the gain initially selected is too low or too high, place the unit in either Standby or Mute mode and
using the front panel buttons, or the remote control, select the new gain for that input. This will store
the new value in the gain memory for the selected input. Do not be afraid to experiment with gain
settings, but try different ones to get the desired listening level for your system. It is almost impossible
to overload the

, and even if overloaded, it will not damage the unit.

Setting the Cartridge Loading Memory
The internal loading circuits are divided into two sections:
One section provides the capacitive loading for MM cartridges as well as the 47Kohm/100Kohm
selection for resistive load.
The other is a plug-in module that controls the resistive loading for MC cartridges (this module
can be seen in Figure 4).
These modules are controlled by a “master” up/down 8-bit binary counter that is “clocked” either by the
“Up/Down” buttons shown in
Figure 1B
or by the “Up/Down” buttons on the remote control shown in
Figure 3
. The loading range and incremental steps are as follows:
