1200 ohms
48 V ±4 V
3300 ohms
6800 ohms
In order to preserve symmetry, use 2 x Rv resistors with a maximum toler-
ance of 0.5% only.
If the amplifier inputs are single-ended (grounded) or have no input trans-
formers, wire either capacitors or optional transformers into the audio lines
to prevent any current leakage into the input stage.
