The RP562 Stereo Tube Sonic Exciter is a two
channel frequency compensation device designed to
add life and animation to your sound.

FEATURES:
• All tube gain circuitr y with proper high-voltage plate
voltages
• Solid state input and output buffer ing only
• 1/4” and XLR inputs and outputs
• Adjustable 18 dB/Octave Subwoofer filter
• Calibrated analog meters - indicate process levels
• Inter nal Power Supply
• Smooth, lively tube sound
• Automatic Sound Separation
• Precise control over low frequencies (bottom)
• Restores the signal’s clarity and definition which
were lost in previous electronic devices

WHAT IS A SONIC EXCITER, AND WHY USE
TUBES?
The frequency range that a human ear can detect is
roughly 20Hz to 20kHz. However, the frequency
response a normal speaker can effectively repro-
duce is much, much less. Additionally, speakers add
distor tion and phase changes that make the sound
different from that of the or iginal material.

A sonic exciter restores clarity and presence to the
processed signal by correcting phase changes and
har monic structure differences. In other words, it
puts the components of the sound back where they
belong.

Using a vacuum tube circuit in this configuration not
only restores the clar ity lost in previous processes, it
adds war mth and a slightly compressed attribute to
the program material. This addition to the sonic
excitement process makes the final sound even
larger, cleaner, and clearer.

All of this magic is done by the use of all-pass filtering,
frequency compensated gain adjustment, and frequency
compensated domain delay. What this means to you is
the elements of your sound are fanned out like a deck of
cards, making each sound more audible and distinct,
reducing the need for high volume and radical equalizer
adjustment.
And there's more. Because of the unique tube design,
the RP562 also has the benefit of natural tube compres-
sion. This makes a more realistic and pleasing sound.
Also because of the all class “A” design, there is en-
hanced second har monic content, making the RP562
even more smooth and musical. Class "A" circuits also
eliminate time constants which cause unwanted "breath-
ing" and "pumping" effects.
The RP562 performs all the necessar y functions of
psychoacoustic enhancement, but with the addition of
tube circuits, the unit becomes a must for any musician,
studio owner, or sound technician.
