SA248 Spectrum Intelligent Filter User Guide 23
players pick attack, and the low frequency oscillator (LFO) modulates the filter back and forth
at a steady rate set by the Speed control in the LFO section. Turning the knob all the way to
the left provides 100% envelope follower control and turning the knob all the way to the
right provides 100% LFO control. Setting the knob anywhere in between creates a mixture of
both types of filter modulation.
• Bass: Boosts or cuts the low frequencies of the wet signal.
• Treble: Boosts or cuts the high frequencies of the wet signal.
• Mix: Sets the ratio between the wet and dry signal. Placing the knob at approximately 12
o’clock creates a 50/50 mixture of wet and dry signal.
• LoRetain Frequency (WET): Rather than a simple Mix control the LoRetain parameter allows
you to split the frequency spectrum of your wet signal, meaning that the Spectrum effect
applies only to the frequencies above a certain cut-off point and leaves the lower frequencies
dry and unaffected. The LoRetain Frequency adjusts the point in the frequency spectrum
where this split occurs. As we turn this knob from left to right the cut-off point moves to
higher frequencies leaving more and more of your low frequency spectrum unaffected.
• Output Volume: Boosts or cuts the overall output level of both the wet and dry signals.
• Output Balance: Balances the level of the wet signals going to Output 1 (Left) and Output 2
(Right). Set the knob to 12 o’clock for an even stereo split to both Outputs. Turning the knob
left shifts the balance to Output 1 and turning the knob right shifts the balance to Output 2.
Voice Controls
The Spectrum features two standard Voices. Each Voice can receive signal from either Mono Input 1,
Mono Input 2, or Stereo Input Mix. Both Voice modules feature the same control set.
• On: Click the On buttons to engage or disengage each individual Voice. If the On button is
green the Voice is engaged.
• Source Pull-Down Menu: Selects between Inputs 1 & 2 as the audio source.
• Destination Pull-Down Menu: Selects whether that Voice is directed to both the Distortion
and Filter modules, only the Filter module, or bypasses both modules and goes directly to the
Output Mixer.
• Level Knob: Sets the Output level of the corresponding Voice. Use each Voice’s dedicated
Level knobs as a mixer for the final preset.
