8、he 545 is simple to use. The amount of gain reduction is adjusted with the DISRUPTION control in conjunction with the X4 switch. The X4 switch multiplies the sensitivity of the sidechain by a factor of four, allowing the 545 to be used effectively on low level signals. Low frequencies are affected m

9、ost significantly, with the effect becoming increasingly less active as frequency rises. Because the resulting distortion is the desired effect, a traditional gain reduction meter is not included. Your ears should be the judge to determine the amount of effect to apply. Compression can be viewed as

10、a byproduct of distortion as in traditional cases. The red LED lights up when gain reduction is taking place in the same manner as the LEDs in the optoisolators, providing an indicator that gain reduction is taking place. The MAKEUP control is an output level control to allow the user to restore lev

11、el lost in gain reduction. As with the DISRUPTION control, the numbers 0 - 40 do not refer to dB or anything like that. They are simply a divisible set of numbers which make recall of settings easy. Finally, the IN switch activates the sidechain. Disengaging this switch silently bypasses the unit, a

15、ATIONS INTRODUCTION Thank you for purchasing the XQP 545 Optical Disrupter. The 545 is compressor that creates an asymmetrical waveform in the low frequencies. There is no clipping, because an amplifier stage is not being overdriven. Instead, the LEDs in the dual VACTROL optoisolators are driven by

16、an AC signal which modulates the audio during gain reduction in a manner that producs even-order harmonic distortion. The 545 is a VPR module (hopefully you are already aware of this) designed to fit into the common 500 series racks orginated by API. It follows the standard API pinout. VPR Alliance approval pending as of 7/30/10. IN X4 DISRUPTION MAKEUP OPTICAL 545 DISRUPTER 0 4 8 12 16 20 24 28 32 36 40 XQP 0 4 8 12 16 20 24 28 32 36 40 XQP
