The outputs are not only separate high and low frequencies, but enhanced for crystal clear highs and lows worthy of Richter scale measurements. You've now got complete control over the tone of your sound. Please review this manual carefully as it contains the information necessary for the proper setup and operation of your new RP221 Bottom Feeder. THE ROLLS SONIC EXCITER - SCE PROCESSING 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.

Connect the High Outputs to an amplifier and speaker combination designed to receive signals above at least 140 Hz. Connect the Sub Outputs to an amplifier/speaker combination designed to receive signals below 140 Hz. Remember to consult the speaker manufacturers owners manuals for proper crossover settings. INPUT LEVEL 0 BOTTOM 0 DEFINITION 0 40 XOVER FREQ 55 80 90 100 120 130 25 Hz 140 SUB OCTAVE SYNTH LEVEL SUB LEVEL ACTIVE 30 27 dB 20 clip - + - + 0 10 0 10 pwr RP221 INPUT LEVEL: Adjusts the amount of input signal to the RP221. CLIP LED: Indicates overload in the input circuitry. If this LED lights, the INPUT LEVEL should be reduced. ACTIVE switch: When pressed in, the sonic exciter and sub-synth circuits are engaged. 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 (sibilance) and sound spread. Setting it at 0 is flat response and minimal spread, 10 is maximum spread and definition. XOVER FREQUENCY: Sets the frequency point at which the high and low frequencies are split. The frequencies above the crossover point are sent to the High Outputs, the frequencies below this point are sent to the Sub Outputs. SUB OCTAVE SYNTH LEVEL: Adjusts the amount of signal coming from the Sub-Octave synthesizer circuitry. The Sub-Octave Synth is a special circuit that divides the low frequency signal (after the crossover) in half, and produces a sub-octave harmonic. This level control then mixes the resulting signal with the Sub Level signal. SUB LEVEL: Adjusts the output level from the Sub Outputs. This includes the low frequencies after the crossover, and the added Sub Octave Synth signals. PWR LED: Indicates that the RP221 is connected to the power adapter, and to an AC outlet. OPERATION SETTING THE INPUT LEVEL After proper setup and connection, play a sample of program material, and test any microphones for a normal operating output level. Adjust the RP221 INPUT LEVEL control to the point where the CLIP LED begins to light, then back off this control slightly until the CLIP LED only lights occasionally. SETTING THE CROSSOVER The XOVER FREQ control sets the frequency point at which the high and low frequencies are split. The frequencies above the crossover point are sent to the HIGH OUTPUT, the frequencies below the crossover point are sent to the SUB OUTPUT. Consult the subwoofer speaker(s) owners manual for the suggested crossover frequency. THE SONIC EXCITER The two controls that make up the Sonic Exciter section of the RP221 are the Bottom and Definition. Start by setting these two controls at the 12 O'clock position. Turning the Bottom control clockwise increases the amount of sub-frequency enhancement, thereby increasing the level of low frequency sound. Turning the Definition control clockwise increases the high frequency enhancement, and increases the amount of high frequency sound (often referred to as sibilance or "sizzle"). Set each of gthese for the desired process amount. THE SUB OCTAVE SYNTHESIZER/SUB LEVEL This control will effect the Sub Output signal only, and must be set carefully. Increasing the amount of the Sub Octave Synthesizer adds extreme low frequencies to the sound. Begin with this control set at 0. With program material playing, slowly and carefully increase the Sub Octave Synth Level until you hear the desired amount of low-end enhancement. Finally, adjust the Sub Level control to match the level of the High Frequency output for the desired mix of frequencies.
