Architects’ and Engineers’ Specification
PLM Series: Powered Loudspeaker Management™
PLM 10000Q
Overview and Functions
The unit shall comprise a two-in/four-out digital loudspeaker drive
processor with power amplifier outputs. Additional capabilities and
facilities shall include load verification and real-time performance
monitoring; low-latency, Ethernet-based audio networking; control
and monitoring of internal parameters from a remote computer; and
optional software integration of industry-standard acoustical measurement tools. All control, monitoring and measurement facilities
shall be remotely accessible via a custom PC software interface supplied with the unit.
Connectors, Network, and User Interfaces
The rear panel shall provide audio inputs for analog (2) and AES digital
(1) audio signals on XLR-F connectors, with link outputs for all three
inputs on adjacent XLR-M connectors. In addition, two EtherCon® housed RJ45 Ethernet jacks shall be provided for networked digital
audio as well as monitoring and control via remote PC. The unit shall
be compatible with use as part of a low-latency, self-configuring digital audio network that supports sampling frequencies from 44.1 to
192 kHz. Output connectors on the unit shall be either binding post
or Neutrik ® Speakon® (2 x NLT4 and 1 x NLT8).
Digital Loudspeaker Processing
The unit shall include two modules of comprehensive digital audio
processing configured specifically for loudspeaker drive applications.
Facilities shall be included for raised cosine equalization, linear-phase
and classical crossovers, peak and rms limiters, and floating ground
isolation. The processor firmware, in conjunction with supplied PC
software, shall accommodate flexible mixing and routing, including
software-driven linkage of processing modules in two or more separate units to function as a single module with extended capabilities.
The front panel user interface shall include a high-brightness 2.5-inch
LCD panel, a moisture-resistant silicone touch pad, and a rotary
encoder. The user interface shall be menu-driven, with screen displays and soft-keys accessing functions of the digital loudspeaker
processor and the power amplifier. Dedicated keys shall be provided
for Mute Enable, Meter and Menu functions. Multi-color LEDs shall
indicate presence of any warning or fault conditions.
The unit shall be supplied with a custom software program for comprehensive monitoring of system status and operating parameters,
as well as control of DSP and amplifier functions. The software
program shall be compatible with use on a tablet PC, and shall offer plug-in integration of SmaartLive ® audio and acoustical measurement tools in the same user interface.
Power Amplifier
Maximum total output of all four channels shall be 10,800 watts.
In discrete four-channel mode, each amplifier channel shall deliver
maximum continuous power as follows: 660 watts into 16 ohms,
1200 watts into 8 ohms; 2300 watts into 4 ohms; 2700 watts
into 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 power
each of the other two channels shall be 2400 watts at 4 ohms and
2900 watts at 2.7 ohms, with output at other impedances as above.
Maximum output voltage per channel shall be 150 V; maximum output current per channel shall be 35.5 Arms. Amplifier gain shall be
adjustable in the DSP input module across a range of 22 to 44 dB in
0.1 dB increments.
Power Supply, Protection, and Cooling
The power supply shall be a regulated switch mode type. The amplifier shall operate from AC line sources of either 230 V nominal or 115
V nominal (not user selectable), with respective operating ranges of
130 – 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 powerup to 5 A. The amplifier shall be equipped with an averaging power
limiter circuit to prevent excessive current draw. The amplifier shall
be cooled by two temperature-controlled, variable-speed fans, with
air flow from front to back. An adaptive fan on/off function shall be
dependent on presence of an output signal.
The unit shall exhibit the following performance parameters:
Frequency response shall be 20 Hz to 20 kHz, +/-0.05 dB at 1 watt
into 8 ohms. Dynamic range with digital inputs (all supported sample rates) shall be greater than 116 dBA. Propagation delay shall not
exceed 1.9 ms in the worst-case scenario. The unit shall include a
DSP-implemented zero overshoot voltage peak limiter individually
adjustable per channel for maximum voltage between 18 and 150 V
in 0.1 V increments.
The 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. The
weight shall be 13 kg (29 lbs). The chassis housing shall be black
painted steel with a black painted steel and aluminum front surround
and handles.
Load Verification and Circuit Protection
The unit’s DSP and on-board firmware, in conjunction with supplied
PC control software and loudspeaker database, shall enable the unit
to verify that loudspeaker loads are connected as intended, and to
identify defective drivers or faulty wiring. The DSP and associated
software also shall allow real-time monitoring of critical performance
parameters for both the power amplifier section and connected loudspeakers. Circuits and sensors shall be provided for warning and protection against VHF (very high frequencies), DC at output, over-temperature, open load, excessive current, and voltage peak clipping.
The unit shall be approved for use as specified by CE, ANSI/UL, ETL
and the FCC. The unit shall be the Lab.gruppen PLM 10000Q.
