Ram-Audio W-series 9044 / 4 x 2200 W 4 Ohms

Beschrijving

High End High-Power Amplifiers

Utilizing state-of-the-art technology RAM Audio introduces the W Series 2 and 4-channel high end power amplifiers with output ratings up to 12 kW . Dual PFC QuantaPulse switched-mode power supplies provide increased, smooth output irrespective of mains fluctuations. Housed in 46 cm deep, 2U rackmountable reinforced steel chassis the 7 high-power models are easily portable weighing in at 10 – 12 kg only.

The W Series features Neutrik XLR and Speakon connectors, a large blue LCD user interface and 13-detent digital encoders for convenient gain, bridge mode, input link and ICL setting. A DSP loudspeaker management system is optionally available.

Main Features

  • high-efficiency power amplifiers with up to 12 kW RMS output power
  • regulated PFC QuantaPulse dual switch-mode power supply
  • digital control with large blue LCD interface
  • temperature and output level indication
  • USB port for firmware updates and DSP control
  • gain, bridge mode, input links and ICL configurable via 13-detent digital encoders on the front panel
  • RAM Audio power management system (PMS)
  • high-efficiency oversized output transistors for maximum reliability under extreme operating conditions
  • easily removable front panel for dust filter cleaning, Neutrik XLR and Speakon connectors

PMS™: a complete Power Management System that monitors the essential parameters for safe operation. It precisely controls the power supply to the amplifier and output power under extreme and dangerous conditions:

  • if the internal operating temperature approaches emergency shutdown during irregular operating conditions,
  • if the power supply draws excessive current under laboratory conditions or during extended acoustic feedback.

ICL™: improved Intelligent Clip Limiting prevents loudspeaker damage while maintaining audio quality and punch under clipping conditions.

QuantaPulse™ Technology: The Soft Switching Resonant QuantaPulse Power Supply is designed to provide plenty of power when needed monitoring the necessary parameters of voltage and current for a controlled performance at all times. Bi-directional data flow between the power supply and power amp module. Two very important characteristics of the QuantaPulse power supply are the optimization against over-voltages and superior reliability.

Merk

Ram-Audio

Ram-audio maakt….. versterkers.….meer niet.
En hoe !... We verkopen en verhuren dit merk al ruim 25 jaar en er staan nog steeds DQL en BUX series amps van 25 jaar geleden storingsvrij hard te werken, na vele klussen on the road , en dat zonder uitval of storingen.
Helaas voor de verkoop: Ram-audio is gewoon te degelijk.

Informeer bij aankoop van RAM-AUDIO wel altijd naar de laatste prijsontwikkelingen.
