LAB GRUPPEN PLM12K44 4-Channel Combines 12000 W Amplifier

เครื่องขยายเสียง (เพาเวอร์แอมป์) แบบ 4 ชาแนล LAB GRUPPEN PLM12K44, มีกำลังขับ 3000 W per channel @ 4 ohms, 1900 W per channel @ 8 ohms, Class TD® output stage, Lake Processing algorithms, Digitally controlled and recallable amplifier gain, LoadSmart load verification

The LAB GRUPPEN PLM 12K44 is the natural successor of the proven, road tested, and trusted Lab.gruppen touring foundation exemplified by the iconic PLM series, but with an additional new powerful feature set: the ability to rationalize power allocation between channels to optimize performance. Now packaged in an extended 4-in, 4-out configuration together with twice the processing power via the latest version 6.3 Lake Controller release, plus industry-standard Dante® networking, the PLM 12K44 sets the benchmark for Powered Loudspeaker Management Systems.

The PLM 12K44 combines four channels of extremely powerful amplification with unrivalled signal processing and audio management. At the core of the system concept is the total integration of all devices – including networking, audio I/O, signal processing, amplifiers, power supply and connected mains supply – allowing complete control and monitoring of the entire platform, resulting in unique operational benefits.

Features:

  • 3000 W per channel @ 2.67 ohms
  • 3000 W per channel @ 4 ohms
  • 2U chassis weighing only 16.5 kg (36 lbs)
  • Class TD® output stage
  • Universal (70 – 265 V) Regulated Switch Mode Power Supply (R.SMPS™) works anywhere in the world
  • Power factor correction (PFC) helps maintain full output during extended power bursts
  • Copper-finned Intercooler® with transverse-mounted output devices
  • Comprehensive loudspeaker preset database
  • LoadSmart™ load verification
  • Dante™ low-latency digital network included as standard
  • Compatible with Lake LM Series, and Lab.gruppen PLM and D Series
  • Primary and secondary network connections
  • Digitally controlled and recallable “amplifier gain” adjustable in 0.1 dB steps
  • Digital output attenuation in 0.25 dB steps from -inf to 0 dB
  • Binding post or Neutrik® speakON® output connectors
  • Digitally implemented, zero-overshoot Inter-Sample
  • Voltage Peak Limiting (ISVPL) adjustable in 0.1 V steps from 17.8 to 194 V
  • Breaker Emulation Limiter (BEL) prevents mains tripping
  • Under-Voltage Limiting (UVL) enables continued operation with mains voltage sags as low as 65 V
  • High-Resolution daylight viewable LCD display
  • Moisture resistant silicone touchpad
