Make sure you read the initial Important Safety Instructions
chapter at the front of this manual.
AC Power Hookup
Plug the female end of the power cord into the PEQ-450’s POWER
INPUT socket and the male (plug) end into a good quality, noise-free
AC power source of the proper rating.
Tip: It’s good practice to not turn on the PEQ-450 until all other
audio cables are hooked up as well. Make sure your amplifier
or powered speakers are switched off when turning the PEQ-
450 on or off to avoid damage.
The PEQ-450 works with any standard line voltage from 100 to 230
volts and comes with a detachable AC line cord suitable for the
destination to which the unit is shipped.
AC Grounding
The line cable is an IEC-spec AC power cable designed to be
connected to a grounded 3-pin outlet, with the third, round pin
connected to ground. Do not substitute any other type of AC cord;
IEC-spec cables of various lengths may be purchased from
electronics stores or your Alesis dealer.
The ground connection is an important safety feature designed to
keep the chassis of electronic devices such as the PEQ-450 at ground
potential. Unfortunately, the presence of a third pin does not always
indicate that an outlet is properly grounded. You may use an AC line
tester to determine this. If the outlet is not grounded, consult with a
licensed electrician. When AC currents are suspected of being highly
unstable in VAC and Hz, a professional power conditioner should be
used.
