USER MANUAL
MC cartridge – 0 ohms to 2550 ohms in 10 ohm steps (Using 0 ohms will result in a shorted
input and very little, if any, signal.)
MM cartridge – 120pF to 1400 pF in 10pF steps. Also the resistive load can be 47Kohms or
100Kohms.
For MM cartridges, the minimum 120pF represents the input capacitance of the
Phono III
, and the upper
limit is restricted to 7-bits on the counter.
When the
Phono III
is turned on by the user for the first time, the loading memory has all “0s” stored for
each input, so it is necessary to provide “baseline” loading data for each input.
5
The baseline data can
be set in any of the operating modes (Standby, Mute, Run). To store the “baseline” data, proceed as
follows:
With the unit turned on, and in either the Standby or Mute mode, select an input to be used.
(You have already selected the cartridge type in
Section 2.1
).
The display will show “0”ohms if you selected a MC cartridge, or “120”pF if a MM cartridge was
selected. If a MM cartridge was selected, the selection of 47Kohm or 100Kohm resistive loading
should have also been made.
Using either the “Up” button on the front panel, shown in Figure 1B, or the “Up” load button on
the remote control, shown in Figure 3, increase the loading to a “baseline” value as
recommended by the cartridge manufacturer, or based on previous listening experience. (If you
overshoot the desired value, use the “Down” buttons to make corrections.) This will be the
“baseline” loading value for that input.
Press either the “Up” or the “Down” button on the front panel to store the “baseline” loading
value.
NOTE:
The “baseline” loading data is
ONLY
stored using the buttons on the front panel.
Using the up or down buttons on the remote control will
NOT
store any data in the loading
memory. (See following paragraph for using the load buttons on the remote.)
Repeat the above process for the other inputs that will be used.
Having put the “baseline” data into the loading memory, it is now possible to use the remote control to
make loading adjustments while listening and not alter the “baseline” data. This permits the user to
make minor changes in the cartridge response for the purposes of enhancing the listening experience
for a particular recording by using the “Up”/”Down” buttons on the remote without changing the
“baseline” data. To return to the stored “baseline” loading value at any time, press the “mute” button
and then the input selection button for the input being used, followed by pressing the “run” button. If
the listener believes that an improved “baseline” loading was obtained by using the buttons on the
remote while listening, it is only necessary to use either the “Up” or “Down” button on the front panel
to store the newly obtained loading value for that input (pressing “mute” is not required).
5
The “baseline” data represents the load values that will be stored in memory for each input/cartridge
combination based on manufacture’s recommendations or listening experience. This value can be easily changed
if listening experiences offer a better value.
