Amplifier manufacturer Linea Research has announced the addition of eight channel 20kW models to its successful M and C series of networked DSP amplifiers. The new touring focused 48M20 and installation targeted 88C20 amplifiers are optimised to deliver 2500W per channel into four ohms with all eight channels driven simultaneously.

“Our existing amplifier models delivered their highest power output into two ohms,” explained Peter Collins, sales manager at Linea Research, “but, of course, two ohms isn’t always ideal, and many of our users prefer to load their amps at four ohms. In developing these new models we’ve been able to effectively double our output and power density into four ohms, giving our customers exactly what they’ve been asking for.”

Both M and C series versions offer networked control, 96kHz DSP signal processing and user FIR filters on every output, along with analogue and AES inputs as standard and a Dante/AES67 option. With four inputs, eight outputs, and full front panel control, the 48M20 is aimed at portable and touring users while the eight input eight output 88C20 provides all the same DSP and control features, but is finished with a blank front panel for tamper proof operation.

“Flexibility is key with all of our products and these are no different,” concluded Collins. ”In one 2u eight channel amplifier, we can now offer anything from a bridged pair giving 5kW at eight ohms, single channels of 2500W at four ohms, and even drive 2500W into a 100v line. Our new amplifiers will be shipping this month.”

Linea Research has also launched an update to its ASC48 DSP System Controller, with the addition of Dante outputs and user-accessible FIR functionality.

Shipping now, all ASC48 processors will come with FIR filters on every output, allowing the user to import files with up to 384 taps at 48kHz or 768 at 96kHz. Fully compatible with FIR design software like Eclipse Audio’s FIR Designer, this new functionality matches that already in Linea Research’s M and C series of networked DSP amplifiers.

Dante-equipped versions of the ASC48 have received an additional upgrade and can now output Dante back onto the network, as well as receiving it. This new functionality allows the ASC48 system controller to pick from almost any part of the signal chain, the physical input, pre or post input processing, or the final processed output, and deliver this signal back onto the Dante network.

“In combination with the existing analogue and AES inputs this new Dante output capability turns the ASC48 into a 12x4x16 routing matrix, including the distribution of post DSP processed signals back onto the network,” said Davey Smalley, director of Linea Research. “These new additions of FIR processing and enhanced Dante flexibility are all the result of feedback from our customers coupled with our drive to continually improve our products.”
