- GAIN
Level adjustment acting simultaneously on both channels for both the moving coil and the
moving magnet sources.
- BACK PANEL IMPEDANCE SWITCHES
Situated above the preamplifier input connectors, six switches are provided to adjust
individually the loading of each input and this separately for each channel.
More, for the Moving magnet inputs, both resitive and capacitive load are provided.
Each switches has 10 positions, numbered 0 to 9.
Here is a table of the values applied for each position of each commutator:
* Commutator MCR-R and MCR-L
(Moving Coil Resitance-Right, and Moving Coil Resistance-Left)
The following values are parallel resistance load applied to the MC inputs.
One commutator controls the right input, the other one the left input.
