MPX 550 Program CMPRSSR In all Cmprssr programs, gain within a range match volume levels between bypassed, and compressed output obtained material. If the System Mode parameter Mix Program, the Mix parameter will automatically Wet, allowing the compressed delay signal output signal present. If the System Mode parameter Mix Mode is set to Global, the Mix parameter set manually. The five compressor-reverb presets offer a reverb component in parallel with a zero-delay dry component. The compressor acts on both. The Mix parameter should be set to Wet, and the effective mix should be adjusted with the Efx Bal parameter.

Presets 242, 243, 244, 247, and 248 are combination compressor and reverb with Dual Stereo (Parallel) routing. Program Lexicon DYNAMICS Note: A few seconds after the Dynamics the Dynamics name will flash panel display. This does not affect audio input output. Dynamics is intended for use in the studio, dynamic processing of stereo signals is required. of its long delay, this preset is not recommended for use in a live performance or as a mix insert. It includes effects that perform peak expansion, compression, and tape saturation in that order. Dynamics includes nine parameters that are divided into three Edit Pages. Peak expansion settings are controlled on the first page, compression settings are controlled on the second page, and tape saturation settings are controlled on the third page. The first page also features a switch that selects between gain reduction and input metering. PEAK EXPANSION Peak expansion is sources that rise above the threshold. In performances with a wide peak expansion can increase sources. For example, for a relatively that swells in volume without the expansion can raise the instrument ExpThrsh (-31 to 0dB) Controls the threshold above which expansion applied. Lower settings enable low-level sound to expand. Higher settings enable only very high-level peaks to expand. ExpLvl (0.0dB to 5.89dB) Controls the amount of expansion that is applied to sound sources that rise above the expansion threshold. The parameter setting defines the maximum increase in signal level due to expansion. Higher settings increase the level of expansion applied. Maximum expansion is applied to signals that rise well above the expansion threshold for longer than 50ms. MPX 550 Program Meters (GR, In) Selects between metering. (See page COMPRESSION Compression is used to lower the sources that rise above an adjustable threshold. Compression can be used of louder sources to those of quieter sources. Ratio (1:1 to 10:1) Determines the level of gain reduction applied when sound source rises above the compression threshold. It can be set in ratios of 1:1, 1.60:1, 2.00:1, 2.66:1, 3.20:4.00:1, 5.33:1, 8.00:1 and 10:1. For each dB rise in input to the compressor, the ratio indicates the fraction of the dB rise in output. For example, when Ratio is set to 4.00:1, the output will rise 0.25dB for each dB rise in input to the compressor. Higher settings will result in more compression. Thresh (-31 to -0dB) Designates the compression sound source must rise above applied. Attack (200 to 3.0msec) Determines how fast the compressor sources that rise above the compression Slower settings allow the signal to rise threshold for short periods of time with minimal compression. Release (4.0 to .30sec) Determines how fast compression is reduced when sound sources fall below the compression threshold. Slower settings reduce compression gradually. Faster settings reduce compression more quickly, causing the level of the sound source to be tracked more closely. . . . continued on page 4-34 Program Lexicon TAPE SATURATION Tape saturation emulates recorded on analog tapes and recorded digitally. Because of the natural peak saturation tapes, sound sources recorded on them seem than the same sound sources recorded digitally. To use this effect, increase the Gain parameter amount of gain used is guided by meter and, more importantly, the ear. Gain levels that are too high can dramatically reduce the of sound sources, possibly causing objectionable distortion - just like real tape. Gain (Min, 1 to 30, Max) Determines average output level. Lower settings prevent signal saturation. Higher settings reduce peaks within the sound source relative to the average level of the sound source, enabling the peak saturation block to reduce peak levels. The setting can be increased to its maximum level without causing digital overload. However, excessive peak saturation may distort the signal.
