LAB GRUPPEN D20:4L 4-Channel Combines 2000 W Amplifier

เครื่องขยายเสียง (เพาเวอร์แอมป์) LAB GRUPPEN D20:4L, with Lake DSP, Total burst power all channels (share among channels with RPM) 2000 W, 4 “Lake class” analog inputs with Iso-Float™ ground isolation, 4 AES inputs, 8 Dual Redundant Dante™ inputs

The D 20:4L is based on the same foundation of robust, high-power amplifier technologies as our renowned PLM Series – an amplifier platform with a proven record of reliability and sonic performance on the world’s most grueling concert tours and in high-profile, large-scale installations.

With the D 20:4L, those same core technologies have been updated and refocused to provide the ultimate solution for the most demanding digitally networked installed sound applications – in stadia, arenas, theme parks, performing arts centers, racecourses and other large commercial sound installations.

In addition to legendary Lab.gruppen reliability and sonic excellence, the D Series incorporates newly refined outputs stage technologies along with installation-targeted hardware and software features that optimize amplifier system design and configuration. Together, these new technologies allow systems integrators to minimize both initial equipment costs and end users’ long-term energy consumption.

Features:

  • Rational Power Management™ (RPM) – True flexibility in allocating total available power output across channel count for most efficient use of system inventory
  • Any channel capable of being significantly scaled up for driving high power elements (e.g. subwoofers)
  • 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 BSS, Q-SYS and MediaMatrix 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™)
  • 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 IDEEA Class D Output Stage with direct drive 70 and V constant voltage systems as well as low impedance
  • 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
