Everything you need, nothing you don’t
The über-simple front panel controls of
these amps give you all of your sound’s vital
signs at a glance. After fl ipping the MAIN
switch, the POWER LED will light when the
amp is ready for action. Both channels have
independent gain dials as well as clip LEDs that
indicate when the signal is distorted and you
need to reduce the gain. There are also SIGNAL
LEDs that light up when a signal is present at
the input.
Panel discussion
A panel of switches found on the back
panel off ers an array of cool options to apply to
both channels of the EP2000 and EP4000. The
Clip Limiter lets you get even more out of the
amplifi er without overdriving either it or your
speaker system. Built-in circuitry automatically
senses when the EP2000 or EP4000 is
being overdriven into “clipping” and then
momentarily reduces the input level to avoid
clipping distortion. This all happens in a few
thousandths of a second, so it’s an inaudible
way of avoiding audible clipping distortion.
Of course, you can turn the Limiter off if you’re
feeling lucky.
Ultra-low frequency sounds (infrasonics) are
caused by rickety stage vibrations, mic thumps
and wind noise. While technically inaudible,
they can cause a huge drain on amp power,
potential damage to your speakers and a
sludgy sound in the audible bass ranges. Both
EP models feature a defeatable Low Cut Filter
that chops off unwanted frequencies below
50Hz or 30Hz (depending on your PA system’s
capabilities).
The same panel contains the switches
that allow you to put these amps to work in
either stereo or bridge (mono) mode. Both the
EP2000 and EP4000 can be linked to additional
power amps by switching into parallel mode.
These amps have guts
There’s plenty of awesome features on the
outside of the EP2000 and EP4000, but there’s
also a team of cool components on the inside
helping it work its magic. They come loaded
with famously reliable Toshiba/Fairchild power
transistors as well as a high-current toroidal
transformer for ultra-high transient response

and further reliability. Independent DC
and thermal overload protection on
each channel automatically protects
the amplifi er and speakers from any
show-stopping meltdowns. There’s no
need for fuses, giving you one fewer
potential mid-gig headache.
The EP2000 and EP4000 have
both XLR and ¼" TRS inputs. Even the
outputs are totally fl exible, consisting
of Speakon-compatible outputs and
fi ve-way binding posts. Whether you’re
dealing with bare wire or boutique
audiophile cabling, the EP2000 and
EP4000 are right at home.

front-to-back cooling system that
keeps these amps working in the mild
temperatures they love, even through
periods of extended use. Finally, an
impact-resistant, all-steel 2U rack-
mount chassis helps these workhorses
stand up to all the rigors of the road.
Accelerated Transient Response
delivers the knock-out punch
It takes huge pulses of energy
(current and voltage) to propel a
woofer cone out fast enough to match
a bass beat. That’s called Transient
Response and it’s the holy grail of
amp designers. By carefully selecting
