POWER STATUS LED
LED indicates power status.
PROCESS ENGAGE
Illuminated push-button that engages the Primary Source Enhancer’s effect.
TIME CONSTANT
Designed to help prevent choppiness in some situations and stop feedback in other situations, by setting how quickly the attenuation occurs in the quiet sections between words or sentences. “A” is the fastest and “F” is the slowest. “A” will quickly soften the level which can be advantageous when the singer is consistent and feedback howl is challenging. “F” is the safest in terms of slowly fading down, but might be a bit slow fading up again, and might be a bit slow for controlling some pesky feedback situations. “C” and “D” are moderate settings that should fit many situations and generally fade down slow enough so that the ends of words are not affected, yet fast enough to control feedback. Choose the most appropriate time constant that doesn’t soften the beginnings and endings of phrases, yet still diminishes the feedback and “boominess” of the signal.
RMS / PEAK
Illuminated push-button that selects between RMS and Peak detection modes. When illuminated, the 5045 is in PEAK mode – useful for detecting faster transient peaks, and for creative dynamic envelope shaping. When not illuminated, the 5045 is in RMS mode, which utilizes a slower, more averaged response characteristic in the sidechain.
THRESHOLD
Sets the dBu level at which the Primary Source Enhancer engages.
PROCESS ACTIVE
This LED indicates when the 5045 is actively affecting signal – a.k.a. when the input signal has overcome the enhancement threshold. Since this LED should generally be illuminated when the desired source is present (a vocalist singing, for example) it is extremely helpful in setting up the 5045 for use.
DEPTH
The “DEPTH” knob sets how much attenuation is applied after the signal falls below where the “THRESHOLD” is set. “0” implies zero attenuation and the 5045 won’t be doing anything. “-10 dB” is moderate attenuation and reasonably safe from accidentally chopping off a word or part of a word. “-20 dB” attenuates deeper but might be a bit choppy. Setting the “DEPTH” control so that it does not chop off bits of quietly spoken words while fighting a difficult feedback problem is the goal, especially with singers that sing quietly one moment and loudly the next while demanding loud monitors.
