Thank you for your purchase of the Bellari RP562 Stereo Tube Sonic
Exciter.The RP562 StereoTube Sonic Exciter is a two channel frequency
compensation device designed to add life and animation to your sound.
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 effec-
tively reproduce is much, much less. Additionally, speakers add distortion
and phase changes that make the sound different from that of the
original material.
A sonic exciter restores clarity and presence to the processed signal by
correcting phase changes and harmonic 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
clarity lost in previous processes, it adds warmth and a slightly com-
pressed 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 com-
pensated 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 because
of the unique tube design, the RP562 also has the benefit of natural tube
compression.This makes a more realistic and pleasing sound.Also
because of the all class “A” design, there is enhanced second harmonic
content, making the RP562 even more smooth and musical.
This product has been designed for years of useful service.We take
pride in our products and appreciate any comments you may have
regarding them.
Please read the following manual carefully to ensure proper operation,
and enjoy your new RP562.
INSPECTION
1.Unpack and Inspect the RP562 package
Your RP562 was carefully packed at the factory in a protective carton.
Nonetheless, be sure to examine the unit and the carton for any signs of
damage that may have occurred during shipping. If obvious physical
damage is noticed, contact the carrier immediately to make a damage
claim.We suggest saving the shipping carton and packing materials for
safely transporting the unit in the future.
2.Please complete the Warranty Registration Card and return it to the
factory. 14
STEREO CONNECTION WITH MONO SUB OUTPUT
The diagram below shows how to connect the RP562 in a stereo configu-
ration with a mono sub-woofer output.
Again, remember to apply power to the RP562 and other devices before
turning on the power amplifiers.

OPERATION
STEREO CONNECTION
The diagram shown below is a stereo connection for your RP562.We
recommend you put the RP562 last in the signal chain. If you have an
EQ or other processor after your mixer's main outputs, insert the RP562
between it and your power amplifier.
If you are connecting the RP562 into a home stereo system, insert the
Sonic Exciter between your signal sources such as tuners, cassette
players, CD players etc. and the power amplifier.
CAUTION: TO AVOID POSSIBLE SPEAKER OR AMPLIFIER DAMAGE,
ALWAYS TURN ON THE RP562 AND OTHER PERIPHERAL EQUIP-
MENT BEFORE TURNING ON THE POWER AMPLIFIERS. ALSO
TURN OFF THE POWER AMPLIFIERS FIRST, BEFORE TURNING
OFF THE RP562 AND OTHER EQUIPMENT.
REAR PANEL DESCRIPTION
POWER CORD: Provides power to the RP562 from a properly grounded
ac outlet.
RIGHT/LEFT XLR OUTPUTS: Balanced outputs for connection a power
amplifier.
RIGHT/LEFT 1/4" OUTPUTS: Unbalanced outputs.
LEFT/RIGHT 1/4" INPUTS: Unbalanced inputs for connection (normally)
to the last device in the signal chain before the power amplifier.
LEFT/RIGHT XLR INPUTS: Balanced inputs. See above.
SUB OUTPUT: 1/4" unbalanced output for connection to the Sub Woofer
power amplifier.
FRONT PANEL DESCRIPTION
SUB FREQUENCY: Sets the highest frequency allowed out of the Sub
Woofer Outputs.This frequency is adjustable between 35Hz and 200
Hz.
SUB LEVEL: Adjusts the output level of the Sub Woofer Outputs.The
level is adjustable between - infinity (off) and a gain of + 20 dB.
SUB CLIP LED: When lit, this LED indicates the signal level is 3 dB
below clipping and there may be distortion in the Sub Woofer circuits.
ACTIVE SWITCH: Engages and disengages the RP562 process.When
out, the unit is bypassed.
BOTTOM: Controls the low frequency cut/boost (flat or no cut/boost is at
about 11 o’clock). There is a 0 to 1/2 turn spectrum spread from mid-
range to bass with this control as well as amplitude control.
DEFINITION: Controls the amount of sonic clarity and sound spread.
Setting it on 0 is flat response and minimal spread, on 10 is maximum
spread and definition. This is also a good setting for constant dispersion
horns.
LEFT/RIGHT LEVEL LEDS: Indicates the output level of each channel.
PWR LED:Indicates that the RP562 is connected to an AC outlet, and
the power is turned on.
POWER SWITCH: Controls the primary power to the RP562.
