LAB GRUPPEN D120:4L 4-Channel COMBINES 12000 W Amplifier

แอมป์ขยายเสียง (เพาเวอร์แอมป์) LAB GRUPPEN D120:4L, with Lake DSP, Up to 3000 W per channel for driving high power elements, 4 “Lake class” analog inputs with Iso-Float™ ground isolation, 4 AES inputs, 8 Dual Redundant Dante™ inputs, Breaker Emulation Limiter (BEL)

The Lab Gruppen D 120:4L offers 12000 W of power combined with the latest Lake DSP, Dante digital audio networking and advanced system integrity monitoring. Based on the renowned PLM series, the D 200:4L offers reliability and superb sonic performance. Housed in a convenient 2U rack spacing the Lab Gruppen D series offer the perfect choice for any professional sound applications.

The Lab Gruppen D series offers total integration of the widest range of digital audio and control protocols, offering powerful and unique benefits and capabilities. The D 120:4L is a highly advanced install-dedicated amplifier, part of Lab Gruppen’s powerful D series. Available in two variants, each with three different power models to suit any specific application. The first variation delivers the proven quality of Lake Processing combined with Dante, while the second features the ground breaking collaboration with Biamp Systems for complete integration with their Tesira DSP platform.

The D series is available in 3 different power configurations of 8000 W, 12000 W and 20000 W and also boasts the introduction of Rational Power Management (RPM). This allows for true flexibility of power allocation without any loss of channel count. It is the most efficient use of the amplifiers inventory.

Features:

  • Rational Power Management™ (RPM) – True flexibility in allocating total available power output across channel count for most efficient use of system inventory
  • Up to 5000 W per channel for driving high power elements (e.g. subwoofers) on all models – up to 2 channels on D 120:4L
  • Lake processing Classic/linear-phase/FIR speaker processing platform with 4 throughputs
  • Input with multitude of automatic redundancy
    • 4 “Lake class” analog inputs with Iso-Float™ ground isolation
    • 4 AES inputs
    • 8 Dual Redundant Dante™ inputs
  • Integration potential with 3rd party matrix systems including MediaMatrix and Q-Sys via purpose developed middleware
  • CAFÉ (Configuring Amplifiers For the Environment) Software incorporating ESP (Equipment Specification Predictor) for design, system planning and equipment planning, installation and commissioning.
  • Regulated Switch-Mode Power Supply (R.SMPS™)
  • Breaker Emulation Limiter (BEL™) to prevent power interruption
  • Under-voltage Limiting (UVL™) for continued operation despite severe voltage drops
  • Best-in-class Power Factor Correction (PFC) with Current Draw Modelling
  • Proven and reliable Class TD® Output Stage with patented Intercooler® high-efficiency cooling system
  • Dedicated on-board surveillance & load monitoring system
  • Redundant audio inputs and onboard system surveillance for mission-critical Voice Alarm applications (PA/VA)
  • Detachable Phoenix plug-in audio connectors for audio I/O
