Linea Research LR-44C06 1500-Watt 4-Channel DSP Amplifier

Linea’s 44C Series of four channel amplifiers are optimised for use in installations. Combining massive power and peerless audio performance with unique DSP, the 44C Series also incorporates many features that ease it’s integration on to both new and legacy systems, the 44C Series represents an unmatched advancement in amplifier technology. The Linea Research LR-44C06 features the following RMS per channel, all 8 channels driven: 1500 W @2 Ohms; 1500 W @4 Ohms; 1500 W @ 8 Ohms; 1500 W @70/100 V.

Sharing the same feature set and form factor as Linea's 88C Series of eight channel amplifiers the 44C Series is available in models that develop between 1,500Watts and 5,000 Watts per channel (up to 10,000 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 optimized 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.

Uniquely, each channel can be configured to deliver its maximum power into 2, 4 or 8 Ohms (2 or 4 Ohms for the C20 model), nominal loads as well as 25V, 70V & 100V constant Voltage (CV) lines. This offers designers and integrators unparalleled flexibility and cost effectiveness.

Ethernet is used for remote control and monitoring while the tamper proof front panel allows easy verification of the operating status and signal levels. Control via Linea’s intuitive SE System Engineer 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. Control from 3rd party systems is also possible via TCPIP, RS232 and RS485 while comprehensive relay and contact closure ports ensure that basic control can be achieved very easily.

The advanced 96 kHz 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.
