RAM Audio – MDi Series

The 9821EMR-AG-HUB is a 1RU platform that is optimized for operation in 10GbE and 25GbE IP SDVN environments, supporting SMPTE ST 302M, AES67*, TDM, MADI and DANTE (up to 512x512 channels of Dante).  MDi Series is the newest solution from RAM Audio for fixed installations, where state-of-the-art amplification technology has been used to manage acoustic systems in the most efficient and greenest way possible, without diminishing quality of sound and dynamics that have always typified RAM Audio amplifiers. A new generation of QuantaPulse switching mode power supplies with Power Factor Correction to improve efficiency, with a schematic thought to give a very high capacity of instantaneous power, together with very evolved high efficiency audio modules in class D with an excellent quality of sound, are the basis on which RAM Audio has developed this new series that is capable of offering the most optimal solution to the very exigent fixed-installations market. Series models:
  • MDi2-1K4
  • MDi2-2K7
  • MDi2-6K
  • MDi4-2K4
  • MDi4-6K
  • MDi4-12K
  • MDi8-2K7

Linea Research – 48M20-Dante

Offering a unique combination of power and audio performance, seamlessly combined with advanced DSP and network control, the 48M Series range of eight channel amplifiers is available in models developing between 400 Watts and 1,250 Watts per channel.

Linea’s 48M Series of eight output channel amplifiers are optimised for live sound applications. Offering a unique combination of massive power and peerless audio performance integrated with unique DSP, the 48M Series represents an unmatched advancement in amplifier technology.

Sharing the same feature set and form factor as Linea's 44M Series of four channel amplifiers the 48M Series is available in models that develop between 400Watts and 2,500 Watts per channel (up to 2,500 Watts for a bridged pair). Unusually these are not, ‘transient’, ‘burst’ or ‘peak’ power figures, they are the power levels that are delivered by all channels simultaneously even when driven with the same dense program material.

With Linea amplifiers there is no need to ration power between channels, you can use all the power you have paid for all the time. This has been independently verified.

Linea can do this because state of the art components and a finely optimised design results in an amplifier that is between 7% and 10% more efficient than any competitive product. This efficiency gain directly translates in to the generation of about half the wasted energy (heat) which is clearly significant. In addition to reducing energy costs high efficiency results in generous power reserves ensuring that pristine sound quality is maintained even under the most extreme conditions.

Ethernet is used for remote control and monitoring while a front panel, optimised for use in challenging live environments, allows full local control of all features. Control via Linea’s intuitive Podware PC application provides many convenient and time saving features such as very flexible management of presets, and Overlay grouping of Mutes, Gains, Delays and EQ across an entire system.

The advanced 96kHz DSP is fully integrated into the product and provides an array of unique and genuinely useful features. Because all aspects of the DSP algorithms are designed and hand crafted in house by Linea, they are not available on products from any other manufacturer. For example, LIR linear phase crossover filters which are as easy to use as more conventional filter shapes, and have less latency than FIR filters. Also the powerful VX Limiter suite which sports Peak, RMS and Excursion limiting, as well as multiband limiting for passive 2-way enclosures.

Adam Hall Group – LD Systems DSP 44 K ProAudio

Designed for the professional audio market, the LD Systems® DSP 44 K power amp was developed in cooperation with Ram Audio, whose products are sold in many countries by Adam Hall Group. Designed for the professional audio market, the LD Systems® DSP 44 K power amp was developed in cooperation with Ram Audio, whose products are sold in many countries by Adam Hall Group. This new powerhouse features a fully-integrated DANTE™ network, a high-performance DSP and controllability via USB and Ethernet using external control PC software. The top-of-the-line power amp can be operated as a two or four-channel device. An impressive four kilowatts provide plenty of power reserves as 4 x 1,000 watts at 4 or 2 ohms or 2 x 2,000 watts (bridge mode) at 8 or 4 ohms. Maximum operational reliability is also guaranteed at 2 ohms. Comprehensive safety features permanently protect the power amps and the system, even in tough situations. FIR/IIR filtering, EQs and crossovers, as well as delay functions, are all part of the overall technology.
