Low output MC - Phono Enhancer Mode (PE Mode)

The diagram below shows the available settings for using the P75 in the
special Phono Enhancer Mode (PE Mode).
One channel is shown for clarity,
the other channel is identical.
Match cartridge coil DC resistance*
(sets output level)
Phono Enhancer mode notes
* The coil resistance is obtained from the cartridge specifications.
This resistance is the DC resistance of the coil, sometimes referred to as
the impedance. It is not the cartridge loading resistance.
An example may help:
Dynavector's DV XX2 mkII specification sheet gives the following:
Impedance
Recommended load resistance
The DC coil resistance for the DV-XX2 mkII is 6Ω therefore in PE mode, set
JB3 & 4 for a low resistance coil (the 4 - 10 Ω range)
See www.dynavector.com for complete Dynavector cartridge specifications.
y,
R = 6 Ω (ohms)
>30 Ω. Ignore this in PE Mode.
