MICROPHONESPLITBOX
The R* resistors are added for mutual decoupling
of the individual outputs. The higher the resistance,
the better the decoupling. At the same time, higher
resistance values also increase the losses. 100
ohms is a convenient compromise. A metal film
resistor with a maximum 1% tolerance should be
chosen for the highest demands.
GROUNDING:
To prevent ground loops, it makes sense to ground
the input to only one output socket. However, this
output socket must always be used first.
