User manual PEAVEY RQ 4300

[. . . ] Intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. CAUTION: To reduce the risk of electric shock, do not remove cover. WARNING: To prevent electrical shock or fire hazard, do not expose this appliance to rain or moisture. Before using this appliance, read the operating guide for further warnings. [. . . ] This switch can also be used to perform the bypass function. When the compressor is assigned to the SUB group, the I/O jack (53) is bypassed. Similarly, when the compressor is being patched externally, the SUB group is bypassed. Engaging the I/O switch allows the operator to hear the difference between the compressed and noncompressed signal when the compressor is being used on the SUB group. (25) GAIN This control sets the output level of the compressor and allows recovery of gain lost by compression. the amount of gain being lost will be represented on the GAIN REDUCTION LEDs (27) , and a similar setting on the GAIN control will approximate pre-compression levels. (26) LINK This switch allows the compressor in SUB group 1 (or 3) to be linked with the compressor in SUB group 2 (or 4). This is useful if the two SUB groups are being used to create a stereo image. When they are linked, the RMS detector voltages are summed together for an accurate representation of the two levels. This locks the compressors together to maintains the stereo image during compression. While linked, the controls in the first of the two linked groups affect both channels. The compressor controls in the second group are disabled. The gain reduction meter for the first group is accurate for both groups and should be used to monitor compressor activity. When the link is enabled the yellow LED will illuminate. NOTE: While linked, the gain reduction meter in the second group may show gain reduction, although it is not a true representation of the compressor activity. (27) GAIN REDUCTION LED's These LEDs graphically show the amount of gain being reduced through compression (-1 to ­12 dB). (28) THRESHOLD This control sets the level at which compression activates and is variable from ­30 dBu to no compression in the OFF position. The adjacent LED (0 dBu) will illuminate when enough signal is present for compression to function properly. SUB GROUPS (29) LEVEL LEDs This display indicates the amount of signal present in the SUB group mix. For example, the SUB fader (33) may be at an acceptable setting, yet the channel signals assigned to the SUB may be approaching clipping. If this is occurring, the channel FADER (16) and GAIN (4) settings may need to be assessed and setting corrections made. NOTE: The CLIP LED can illuminate before the rest of the array indicating the summing amp is clippping. [. . . ] For example, near or in a bathtub, swimming pool, sink, wet basement, etc. Do not block any of the ventilation openings. install in accordance with manufacturer's instructions. It should not be placed flat against a wall or placed in a built-in enclosure that will impede the flow of cooling air. [. . . ]
