DESCRIPTION

The PTA5000-I is a self-powered Minima One™, full range, loudspeaker system
designed for permanent installation, offering both high delity and high efciency. The
Time-Aligned™ studio quality sound provides detail and clarity not found in other
designs. The PTA5000-I has a rugged birch plywood enclosure nished with our
beautiful utility black textured nish and a black steel grille. Optional ying attachment

points allow for safe and convenient rigging.

The audio input incorporates an InGenius® balanced line receiver providing very high

common mode rejection to eliminate noise often present in systems with less
optimized grounding and wiring schemes. The internal Minima One™ amplier
incorporates a high efciency low power consumption green design with advanced

digital switching to automatically accept any line voltage from 88 to 270 volts. Low

voltage contacts are provided for installations to remotely turn the amplier on and off.

PTA5000-I TIME-ALIGN

ABOUT TIME-ALIGN® TECHNOLOGY

Time-Align® assures that the fundamental and
overtones of a complex, transient, acoustical signal are
presented to the listener in the same relationship as the
electrical signal at the input terminals of the
loudspeaker. The conventional loudspeaker spreads out
the sound in time. When a rapid series of transients
occur the results are blurring and lost detail. With
Time-Align®, a transient is presented as a tight package
of energy, with the same time relationships as the
natural sound. This means that a rapid series of
transients will be heard clearly.

True Time-Alignment™ requires much more than just

physically lining up the loudspeaker components. It

requires consideration of the driver placement, driver

delay and adjustment of the crossover delay parameters.

This achieves the precise simultaneous acoustical arrival
time of each driver throughout the crossover region.

The rst Time-Aligned™ Loudspeaker was invented by
EM Long Associates in 1976 utilizing the Time-Align®

generator invented and built by Ronnald Wickersham. In

1980 Bag End® incorporated Time-Align® technology

into our full range loudspeaker systems. Along with
state-of-the-art laboratory instruments, the proprietary
Time-Align® generator is still in use today to verify the
time domain performance of our loudspeaker systems.
When comparing a genuine Bag End® Time-Aligned™
loudspeaker system to any other, our technology and
design is easy to hear and appreciate. The dramatic
clarity, realism, and overall pleasant sound of our

Time-Aligned™ systems are well noted worldwide.

ABOUT MINIMA ONE™

The Minima One™ is both a high delity and a high
efciency amplier. With efciency well over 80%, the
Minima One™ provides more power to the loudspeakers
and creates less heat in the amplier. In real world

applications there is practically no heat emitted from the

amplier and thus it requires no cooling fan.

Incorporating patented technology the comparison circuit

of the Minima One™ corrects every single cycle to drive

®

error to zero at the end of each cycle. On average, every
4 microseconds, the one cycle modulator transforms and

amplies the input signal into the ideal natural pulse

width modulation. Switching at 250 kHz with the single
cycle error correction insures extremely low distortion
and high reliability. The power factor corrected AC
power input, automatically and continuously adapts to
any voltage between 88 and 270 volts. The Minima

One™ is convenient and stable to operate on any power

grid in the world.

ABOUT BAG END® LOUDSPEAKERS

Bag End loudspeakers began in 1976 in a small shop by

people dedicated to the pursuit of making high quality
loudspeaker systems. Over the decades Bag End® has
employed the very best construction techniques and
innovative acoustical designs into their products. The
ground breaking introductions of the Time-Align® and

ELF™ Technologies into sound reinforcement and studio
monitor loudspeakers in the 1980’s was followed by
Minima One™ self-powered systems and the highly
unique E-Trap™, electronic bass trap. Over the decades,

Bag End® has been a leader in providing uniquely good
sounding products and extraordinary service to our
customers world wide.
