Sequential Prophet VS - Power Connection; Power on

14
POWER CONNECTION
1. Check that the Prophet VS power switch is set to OFF position.
2. Connect the power cable to the Prophet VS AC IN.
3. Connect the power cable to a properly-grounded three-prong outlet.
4. Plug all other equipment such as eects devices, mixers, ampliers and
recorders into the same outlet.
WARNING! Do not overload. When in doubt, consult an electrician. The
Prophet VS comes with a three-prong power plug to ensure safe grounding
with other equipment. The ground prong is connected directly to the metal
chassis. Because of this AC ground, a "ground loop" will often be created
when an audio cable is connected between the Prophet VS and its amplier.
As a result, low-level hum may occur. The hum level will depend on exactly
how the synthesizer and amplier are connected to the AC. Defeating the AC
ground with a two-prong adapter will usually defeat the hum but this practice
can set up a shock hazard between the units. For minimal hum, use the same
AC outlet for the Prophet VS and its amplier, and all associated equipment.
This should reduce the hum to an acceptable level. To prevent potentially lethal
shocks, it is up to you to check the power and ground interconnections of the
Prophet VS and all other instruments and equipment in use. Sequential is not
responsible for any equipment failure due to incorrect AC power connections,
and is not liable for any personal injury due to electrical shocks as a result of
unsafe grounding practices. As you probably know, many older buildings and
clubs are notorious for their poor quality AC wiring. We therefore urge you to
use one of the several "ground-checking" devices available on the market to
verify AC connections.
POWER ON
1. Set up as described above.
2. Switch Prophet VS POWER switch to ON.
After a moment or two, the following appears in the liquid- crystal display
(LCD):
PROPHET VS
Sequential r(software level)
for three seconds, then:
PROPHET VS
I NT# 00 (name)
CAUTION! Before playing any key, rst check that Master Volume is reduced
to minimum. This may keep you from accidentally blowing out speakers (or
your ears).
3. Switch power on to your preamp or mixer, if used, then switch amplier power
on. Switching the equipment on in this order prevents loud pops.
