Volume Range Jumpers
Two jumpers are provided to set the volume range. The range jumpers are located just
inside the front panel to the right of the volume control as you look at the front panel.
The volume knob and nut must be carefully removed and the four bolts holding the front
panel on. Take care to get the panel fully seated when reinstalling. The internal gain
jumpers behind the front panel should ideally be selected so that the volume knob is
rotated about 50% or 12:00 position at normal listening levels. If the volume is too loud
when you have the volume knob at minimum, set the internal gain jumpers to the next
setting. The settings are illustrated on the circuit board. Three volume ranges are
possible. The range setting provides a
lower volume extreme
. It does not affect the
maximum volume, only the minimum volume. If the range jumpers are set for “Min”, the
volume will have the least range, so the lowest volume will still be loud. If the range
jumpers are set for “Max”, the volume control when at the minimum will be very quiet.
This allows the volume to be tailored so that a fairly wide arc can be used in adjustment
for track-to-track amplitude variation.
