**IMPORTANT
**
If using a 100V line signal, you
MUST set the attenuator to the
highest setting (J1 + J5)
BEFORE turning your TDS1 on
for the first time. There is a risk
of damaging the input circuits if
you ignore this advice.

As shown in the drawing,
the attenuator is selected
(J1) and the unit set for a
15V (J8) input signal.
This might be typical of a
low impedance loudspeaker where the signal is taken from directly across the loudspeaker.
Always start with link in position J5 and move towards J10 to set a sensible volume with the
gain control in mid position. LED 5 should flash faintly in sympathy with the input signal.
