User manual DYNACORD PAA 990 SERVICE MANUAL

[. . . ] Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or orbjects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. Do not expose this equipment to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on the equipment. To completely disconnect this equipment from the AC Mains, disconnect the power supply cord plug from the AC receptacle. The mains plug of the power supply cord shall remain readily operable. [. . . ] The Constant-Directivity HF horn has been integrated into the baffle by CAD methods. nominal coverage angle of the cabinet is 80° * 40° , horizontal * vertical respectively. The built-in digital power amplifiers are working in biamped operation and are controlled by an electronic xover circuit that has been designed to optimally match the transducers' acoustic characteristics. The multitude of connection and setting facilities (MIC, LINE, AUX) allows using the D 11A in many creative ways. The master signal can be daisy-chained to a second D 11A cabinet via a regular XLR microphone cable. The built-in level control VOLUME allows easy adjustment of the required sound pressure level. the D 11A is connected to the mains via a locked IEC inlet that guarantees a hassle-free operation. Extremely durable acoustic foam mounted to a strong powder-coated steel grille protects the loudspeaker components against any mechanical damage. CAUTION: Do not ship the cabinet in any other than its original packaging. When shipping the cabinet make sure to always use its original box and packaging materials. HINT: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. Press the yellow button at the plug to disconnect the power cord. 12 INPUT CONNECTOR FOR AUDIO SIGNAL (LINE IN) LINE IN is an electronically balanced input for connecting highimpedance audio signal sources like mixers, electronic music instruments like keyboards, guitars and bass guitars with built-in active electronics. It is possible to connect balanced as well as unbalanced gear at the LINE IN input using an monaural or stereo phone plug cable or XLR-type plug cable. Balanced connection is preferable whenever the source unit has a balanced output stage. Following this advice will provide you with the advantage of less interference that is introduced from external hum or HF-induction. CAUTION: Before making any connections or disconnections, make sure to set the level control to the counterclockwise stop. 7 AUX LEVEL CONTROL (AUX LEVEL) This control is used to adjust the input level of the signal source that is connected to AUX IN L / R input. 13 OUTPUT CONNECTOR FOR AUDIO SIGNAL (LINE THRU) This electronically balanced output provides the carried through audio signal from the LINE IN connector. It can be used to feed additional external equipment (e. The level of the output signal is independent of the setting of the Master level control ("Pre Fader"). For connecting audio signal sources to the D 11A, we recommend using cable with balanced XLR-type or stereo phone plug connectors. [. . . ] Using suitable XLR-type cables connect the Master Outputs of your mixing console, e. Position the master faders on the mixer to their minimum setting.
