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.

LD Systems MAUI 44 active column PA system with LECC DSP

The MAUI 44 is the flagship of the LD Systems MAUI series and offers an enormous 1,600 watts of total output (RMS) with a frequency response of 40 Hz to 20 kHz and a sound-level pressure of 129 dB (peak). With its outstanding sound properties and wide-ranging functions, this compact column PA is perfect for musicians, DJs and solo entertainers as well as for permanent installations.

The housing of the bandpass subwoofer is made of rugged 15 mm birch plywood and fitted with two 2 x 12" neodymium woofers as well as two Hypex modules with separate switching power supplies. The four frequency groups of the vertical array system consist of a total of 16 3.5" neodymium speakers with die-cast basket and integrated heat sink along with two 1" Celestion HF drivers with wave guide. They are operated via 4 dedicated class-D power amps.

In terms of connections, the MAUI 44 offers both combo sockets (XLR/6.3 mm jack) and RCA inputs. Total and subwoofer levels can be individually adjusted, providing a perfectly balanced sound in every situation with a crystal-clear treble, a crisp mid-range and a powerful bass. The LD Systems LECC DSP (limiter, equalizer, compressor and crossover) along with two additional limiters provide distortion-free audio reproduction with an extended dynamic range, guaranteeing safe, reliable operation with effective protection circuits to prevent short circuiting, overcurrent and overvoltage.

Designed for simple transportation, the MAUI 44 consists of a subwoofer and an aluminium array with a total weight of less than 60 kg. Special multi-pin inputs reduce set-up time to a minimum, and thanks to its exceptional feedback resistance and extremely wide horizontal coverage of 120°, the system does without additional monitors.
