Clip Indicators

Two red LEDs illuminate if the headroom has been exceeded. This can occur by driving a signal too hard into

the EQ, or by applying too much boost in any of the bands. Clip detectors are located at the output of the lter

stage. If clipping does occur, lower the input level feeding into the unit until the LEDs stop blinking.

P-Filter EQ

The P-Filter EQ is organized into 2 sections (low freq and high freq). Each frequency section (high/low)

features separate boost and cut controls. This allows the unique ability to alter and warp the response of the lter

as will be explored in Part VI, EQ Filter Sections in Depth. The PEQ low freq section has a single frequency

selector button that controls both the cut and boost. The PEQ high frequency selectors have separate buttons to

allow boosting and cutting simultaneously across different frequencies. This allows the opportunity for highly

creative sound shaping, making the EQ502P have the power of a 3-band equalizer or even more, as described in

Part VI.

The Low Frequency P-Filter is a xed shelf with a constant slope. The P-Filter bandwidth control in the right

middle of the section controls the width of the High Frequency P-Filter only. The following picture shows the

P-Filter bandwidth control in its “sharp” position.The broader (1-sharp, 4- broad) the bandwidth, the less the

maximum available boost. As with all equalizers, learn their characteristics and then work by ear. Question: “How

much boost do you need?” Answer: “As much as you need to sound good.”The frequency selectors for each High/

Low lter are switched, and displayed on the front panel in CPS or KCS. (Cycles Per Second = Hertz, Kilocycles

Per Second = kHz). The P-Filter Low band has a 2 button increment/decrement frequency selector for both the

Boost and Attenuation controls (in CPS/Hz). The High band lter has two separate frequency selectors for Boost

and Attenuation. The Attenuation frequency selector is a single button selector that rotates through all choices.

The P-lter Boost frequency selector is a 2 button increment/decrement selector (in KCS/kHz).
