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.

RDL – SF-NP35E

The SF-NP35E is an audio power amplifier that converts one Dante network audio channel to a 70 V or 100 V constant voltage amplified output.  The SF-NP35E is an audio power amplifier that converts one Dante network audio channel to a 70 V or 100 V constant voltage amplified output. The output provides 35 watts for a network digital audio level of 0 dBFS. Special software is not required to configure the module. The SF-NP35E is equipped to operate from a PoE++ enabled network switch. The SF-NP35E may be powered from an external 24 Vdc power supply, available separately. If a PoE++ powered device instantaneously demands excessive power from a PoE++ port, that port can shut off its output voltage, causing a prolonged disruption of the device operation. The SF-NP35E monitors the amplifier power and limits the current to protect the PoE++ port against shutting down even during extreme feedback or square wave modulation conditions. A red rear-panel PORT PROTECT LED flashes when the SF-NP35E reduces power consumption to prevent shutdown of the PoE++ port voltage. The SF-NP35E is equipped with an internal VCA for setting the output level. A detachable terminal block provides for the connection of an external 10 KΩ potentiometer or a 0 to 10 Vdc control voltage. The amplifier gain remains at maximum when the VCA input terminal is not connected. RDL remote controls are available to provide single-turn, multi-turn (rotary encoder) or pushbutton (ramp or fixed level selection) user level control. VCA control insures long term noise-free level adjustment. The module is equipped with both thermal and output short-circuit protection. The high-efficiency Class D output stage produces minimal heat for all levels of expected voice or music modulation. An LED MUTE indicator glows yellow when the output is muted. Valid synchronization to the Dante network is indicated by a green LED visible from the front of the unit. The SF-NP35E is constructed in a durable, professional all-metal enclosure suitable for free-standing, surface-mounted or rack-mounted operation. This full-featured SYSFLEX product is engineered and manufactured in the U.S.A for continuous duty in demanding installations. The versatility of SYSFLEX products adds enormous flexibility in the design and installation of professional A/V systems. Features
