User manual PEAVEY CEL 2

[. . . ] 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. [. . . ] If there is nothing plugged into the side chain jack at the back of the unit, it connects the opposite channel's signal to the detector and uses it for control, making this channel reduce amplitude (or duck) when a signal is present on the other channel. The 1/4" jacks are connected together and the XLR jacks are connected together. (13) STEREO LINK: If the compressor is to be used with stereo signals, the link switch should be pressed. It sums the RMS detector voltages together for an accurate representation of the two levels, and locks the channels together to maintain the stereo image during compression. When the link switch is pressed, all of channel A's controls except the output level affect both channels. The controls for channel B are disabled except its output level. as a reminder of this , the gain reduction meter for channel B is disconnected. The gain reduction meter for channel A is accurate for both channels and should be used to monitor VCA activity. When the stereo link is enabled the LED will illuminate (14) POWER SWITCH: Power is applied when this switch is pressed. As with all devices, the power to external devices should be applied first, then the mixer and finally the power amp to minimize turn on transients. (15) POWER LED Indicates that AC mains power is connected and power switch is in the on position. If this jack is used, the input/output TRS jack (#18) becomes an input only (tip) jack. (18) DETECTOR SIDE CHAIN INSERT: 1/4" stereo (TRS) jack which allows an external device (such as a graphic EQ) to be inserted into the detector's signal path. the tip has the send signal , the ring is the return input. A switch in the jack normally connects the return (ring) to the other channel's send (tip) until a plug is inserted. This gives ducking capabilities without patching. (19) INPUT/OUTPUT: A dual function 1/4" TRS jack that has both input and output signals configured so that a standard (not cross wired) stereo shielded cable can be used to plug into the TRS insert of a mixer. (The tip is the compressor input , the ring is the output , which match the insert jack wiring of all current Peavey mixers. ) If the unbalanced output jack (#17) is used, the ring connection (output) of this jack is disconnected, and it becomes an input only jack (tip). (21) A/C POWER INLET: This is the receptacle for an IEC line cord, which provides AC power to the CELTM 2. Connect the line cord to this connector to provide power to the unit. Damage to the equipment may result if improper line voltage is used (see line voltage marking on unit). [. . . ] 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. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat. [. . . ]
