WHAT IS A SONIC EXCITER?
The human ear can detect a frequency range of roughly 20Hz to 20kHz.However,
the frequency response that a normal speaker can effectively reproduce is much,
much less.Additionally, speakers add distortion and phase changes that make the
sound quite 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.
All of this magic is done by the use of all-pass filtering, frequency compensated
gain adjustment, and compensated frequency 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.

AMPLIFIER

FRONT PANEL DESCRIPTION
SUB FREQUENCY:Sets the highest frequency allow ed out of the Sub W oofer
Outputs.This frequency is adjustable between 35Hz and 200Hz.
SUB LEVEL: Adjusts the output level of the Sub W oofer Outputs.The levelis
adjustable between -infinity (off) and a gain of +20 dB .
SUB CLIP LED: When lit, this LED indicates the signal level is 3 dB belo w clipping
and there may be distor tion in the Sub W oofer circuits .
ACTIVE SWITCH: Engages and disengages the RP262 process.When out, the
eff ect is bypassed.
B O T TO M : Controls the lo w frequency cut/boost (flat or no cut/boost is at about 11
O’clock). There is a 0 to 1/2 tur n spectr um spread from mid-range to bass with
this control as w ell as amplitude control.
DEFINITION: Controls the amount of sonic clar ity 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 hor ns.
LEFT/RIGHT LEVEL LEDS: Indicates the output level of each channel.
PWR LED: Indicates that the RP262 is connected to an AC outlet, and the pow er
istur ned on.
P OWER SWITCH: Controls the pr imar y pow er to the RP262.

OPERATION
STEREO CONNECTION
The diagram shown below is a stereo connection example for the RP262. We
recommend you put the RP262 last in the signal chain. Ifyou have an EQ or other
processor after your mixer’s main outputs, inser t the RP262 between it and your
po w er amplifier .
Ifyou are connecting the RP262 into a home stereo system, inser t the Sonic
Exciter between your signal sources such as tuners, cassette pla yers , CD pla yers
etc. and the pow er amplifier.
C AUTION: TO AVOID POSSIBLE SPEAKER OR AMPLIFIER DA M AGE, ALW AY S
TURN ON THE RP262 AND OTHER PERIPHERAL EQUIPMENT BEFORE
TURNING ON THE POWER AMPLIFIERS.ALSO TURN OFF THE POW E R
AMPLIFIERS FIRST, BEFORE TURNING OFF THE RP262 AND OTHER EQUIP-
MENT.
