AES-PLM10000Q_V2Overview and FunctionsThe unit shall comprise a two-in/four-out digital loudspeaker driveprocessor with power amplifier outputs. Additional capabilities andfacilities shall include load verification and real-time performancemonitoring; low-latency, Ethernet-based audio networking; controland monitoring of internal parameters from a remote computer; andoptional software integration of industry-standard acoustical mea-surement tools. All control, monitoring and measurement facilitiesshall be remotely accessible via a custom PC software interface sup-plied with the unit.Digital Loudspeaker ProcessingThe unit shall include two modules of comprehensive digital audioprocessing configured specifically for loudspeaker drive applications.Facilities shall be included for raised cosine equalization, linear-phaseand classical crossovers, peak and rms limiters, and floating groundisolation. The processor firmware, in conjunction with supplied PCsoftware, shall accommodate flexible mixing and routing, includingsoftware-driven linkage of processing modules in two or more sepa-rate units to function as a single module with extended capabilities.Power AmplifierMaximum total output of all four channels shall be 10,800 watts.In discrete four-channel mode, each amplifier channel shall delivermaximum continuous power as follows: 660 watts into 16 ohms,1200 watts into 8 ohms; 2300 watts into 4 ohms; 2700 wattsinto 2.7 ohms; or 2350 watts into 2 ohms. When one channel pair(A - B or C - D) is driven at -3 dB, maximum continuous output powereach of the other two channels shall be 2400 watts at 4 ohms and2900 watts at 2.7 ohms, with output at other impedances as above.Maximum output voltage per channel shall be 150 V; maximum out-put current per channel shall be 35.5 Arms. Amplifier gain shall beadjustable in the DSP input module across a range of 22 to 44 dB in0.1 dB increments.The unit shall exhibit the following performance parameters:Frequency response shall be 20 Hz to 20 kHz, +/-0.05 dB at 1 wattinto 8 ohms. Dynamic range with digital inputs (all supported sam-ple rates) shall be greater than 116 dBA. Propagation delay shall notexceed 1.9 ms in the worst-case scenario. The unit shall include aDSP-implemented zero overshoot voltage peak limiter individuallyadjustable per channel for maximum voltage between 18 and 150 Vin 0.1 V increments.Load Verification and Circuit ProtectionThe unit’s DSP and on-board firmware, in conjunction with suppliedPC control software and loudspeaker database, shall enable the unitto verify that loudspeaker loads are connected as intended, and toidentify defective drivers or faulty wiring. The DSP and associatedsoftware also shall allow real-time monitoring of critical performanceparameters for both the power amplifier section and connected loud-speakers. Circuits and sensors shall be provided for warning and pro-tection against VHF (very high frequencies), DC at output, over-tem-perature, open load, excessive current, and voltage peak clipping.Connectors, Network, and User InterfacesThe rear panel shall provide audio inputs for analog (2) and AES digital(1) audio signals on XLR-F connectors, with link outputs for all threeinputs on adjacent XLR-M connectors. In addition, two EtherCon ® -housed RJ45 Ethernet jacks shall be provided for networked digitalaudio as well as monitoring and control via remote PC. The unit shallbe compatible with use as part of a low-latency, self-configuring digi-tal audio network that supports sampling frequencies from 44.1 to192 kHz. Output connectors on the unit shall be either binding postor Neutrik ® Speakon ® (2 x NLT4 and 1 x NLT8).The front panel user interface shall include a high-brightness 2.5-inchLCD panel, a moisture-resistant silicone touch pad, and a rotaryencoder. The user interface shall be menu-driven, with screen dis-plays and soft-keys accessing functions of the digital loudspeakerprocessor and the power amplifier. Dedicated keys shall be providedfor Mute Enable, Meter and Menu functions. Multi-color LEDs shallindicate presence of any warning or fault conditions.The unit shall be supplied with a custom software program for com-prehensive monitoring of system status and operating parameters,as well as control of DSP and amplifier functions. The softwareprogram shall be compatible with use on a tablet PC, and shall of-fer plug-in integration of SmaartLive ® audio and acoustical measure-ment tools in the same user interface.Power Supply, Protection, and CoolingThe power supply shall be a regulated switch mode type. The ampli-fier shall operate from AC line sources of either 230 V nominal or 115V nominal (not user selectable), with respective operating ranges of130 – 265 V and 65 – 135 V at line frequencies of 50 Hz or 60 Hz.Minimum power-up voltages shall be 171 V (230 V nominal) and 85 V(115 V nominal). A soft start circuit shall limit current inrush at power-up to 5 A. The amplifier shall be equipped with an averaging powerlimiter circuit to prevent excessive current draw. The amplifier shallbe cooled by two temperature-controlled, variable-speed fans, withair flow from front to back. An adaptive fan on/off function shall bedependent on presence of an output signal.PhysicalThe unit shall be 483 mm (19 in.) wide, 88 mm (3.5 in / 2 U) high,and 470 mm (18.5 in.) deep including handles and rear support. Theweight shall be 13 kg (29 lbs). The chassis housing shall be blackpainted steel with a black painted steel and aluminum front surroundand handles.The unit shall be approved for use as specified by CE, ANSI/UL, ETLand the FCC. The unit shall be the Lab.gruppen PLM 10000Q. |
