Danley Gets Amped Up!


It’s been twelve years since Danley Sound Labs first introduced Tom Danley’s innovative Synergy Horn loudspeakers and Tapped Horn subwoofers to the world. In that time, the company has rolled out several other equally-innovative loudspeaker technologies, such as the SBH Series of column form factor loudspeakers and the Jericho Horn Series of massive stadium-grade loudspeakers. Now Danley offers the DNA Series of amplifiers with a library of onboard DSP presets for every Danley loudspeaker and subwoofer, rugged reliability, luscious 96kHz transparency, multiple modes of flexible loudspeaker protection, advanced power handling and protection, and easy networkable monitoring and remote control. And if all that weren’t enough, they pack a ton of power into four channels and two rack spaces: the DNA 5k4c, DNA 10k4 Pro, and DNA 20k4 Pro models rate 5000, 10,000, and 20,000 watts total output!

“One of the huge benefits of the Danley DNA Series amplifiers is that they come with built-in DSP presets for all of the Danley loudspeaker and subwoofer products,” said Josh Millward, whose official title, “systems application engineer,” is perhaps less descriptive of his day-to-day activities than is his unofficial title – The Amp Guy. “They form an integrated system right out of the box. There’s no need to mix and match, and testing and tuning becomes a much simpler process. Integrators can start tuning a system in the optimal sweet spot and make room- and application-specific adjustments from there.” The DNA amps’ DSP resources have all of the frequency- and dynamic-domain tools that one would expect, along with Danley’s proprietary linear phase crossover, which works its magic without resorting to latency-inducing FIR filters.

Of course, the Danley DNA amplifiers have the reliability, sound quality, and power needed in modern, mission-critical applications. In the year that Danley has been shipping them, the England-built DNA units have had remarkably few failures. The DNA sound quality is commensurate with Danley’s famous loudspeaker and subwoofer fidelity, and all DSP functions operate at 24-bit/96kHz, delivering greater resolution and lower latency than industry-standard 48kHz units.

The Danley DNA design team thought of all the ways that a loudspeaker or subwoofer can be destroyed by an amplifier and then provided a robust means of protection against each one. Advanced DSP limiting allows users to specify, in voltage, a maximum RMS output and a maximum peak output. “The RMS/Peak limiter alone is a great feature, but we’ve added additional layers of protection,” Millward said. “Each output channel has a dedicated thermal limiter and a dedicated excursion limiter. Even the RMS/Peak limiter’s functionality can be optimized with a ‘VX’ function, which essentially straps a crossover to it so that passive Danley boxes can have separate limits for high-frequency compression drivers versus low-frequency woofers.”

All the Danley DNA amplifiers have international power supplies that can plug right into 120V or 240V sources without missing a beat, along with advanced circuit protection. “Say you’re plugging a DNA amplifier into a 20-amp outlet,” explained Millward, “you can set the amp’s ‘external breaker protection’ so that it knows it’s plugged into a 20-amp circuit. The amp will monitor its performance and limit so as to draw less than 20 amps. Of course, that limits the output, but that outcome is way better than tripping a circuit breaker and having the event come to a silent and awkward halt!”

Onboard, easy-to-implement network capabilities round out the Danley DNA amplifier feature set. The amps can be connected to standard Ethernet networks for monitoring and control. The connections are easy, secure, and robust.
