Voltage Output Mode:
Voltage Output Mode
is used to adjust the output voltage the PSU reverts
to after the platter has reached operating speed. The motor requires much more torque at start up
than it does once the platter is on speed; by reducing the running voltage once the platter is moving,
vibration and noise are greatly reduced. The PSU will always assert the maximum output voltage
when starting, or changing speeds, then revert to the programmed lower voltage after approximately
3 seconds.
Voltage Output Mode
has separate adjustments for 33.3 and 45 RPM; both can be
selected, displayed and adjusted while in
Voltage Output Mode
.
Enter
Voltage Output Mode
from
Standby Mode
by holding the
Minus
button; press and release
the
Stby
button. The display will show
:
The display will then indicate the current speed selection (33.3/45.0) and start the turntable motor
rotating. The display will then show the current reduced output voltage for the selected speed; range
is approximately 75%-100% of the maximum output voltage: 13-16VAC in 0.1V steps for 16V
supplies, 18-24VAC in 0.2V steps for 24V supplies and 85-115V in 1V steps for 120V supplies.
The following indicates a voltage of 95V for a 120V supply:
Increase or decrease the output voltage for the selected speed by pressing and releasing the
Plus
or
Minus
buttons until the desired voltage is displayed or measured with a voltmeter. Pressing and
holding the
Plus
or
Minus
buttons will automatically increase or decrease the voltage at a rate of
8 times per second.
