Ashly DSP-2

When you add a Protea DSP Option Card to your PE-Series amplifier, you have just simplified system implementation for many applications in live sound, commercial sound reinforcement and installations. Best of all, standard Ethernet protocol (auto or manual IP configuring), a PC and Ashly's easy to understand and navigate Protea Software is used to control everything.

Or, do it wireless. Protea mobile is a software application enabling you wireless control of PE-Series amplifiers and the DSP-1 and DSP-2 Option Cards for the PE-Series amplifiers.

Protea DSP Option Cards use a SHARC 200 MHz, 32-bit floating-point processor and operate from 48 to 96kHz with a 24-bit AD/DA. Both the XLR and Euroblock versions offer both analog and digital (AES3) inputs and two additional processed output channels to drive additional amplifier channels. (One card will control two 2-channel amps.)

Protea DSP cards have an extensive DSP library including: a full set of filter types for graphic, parametric, notch and shelving equalization. Additionally, there are Bessel, Butterworth and Linkwitz/Riley high and low pass crossover filters with slopes of up to 48dB/octave. For phase correction, Ashly has included all pass filters as an option. Additional processing blocks include: signal delay, compressor/limiter, gate, matrix mixer, signal generators (sinewave, white and pink noise) and metering.

All DSP functions use a "Click and Hot-Plug" user interface to place processor blocks in the signal chain. This method allows you to select a processing block and place it wherever you need it in your signal chain. The process is seamless and in real time, with no need to wait for your system to recalculate or recompile its settings.

Remote control of the front panel attenuators, power standby/power down and recall of up to three presets can be done using the contact closure terminals.

Installation is quite simple. Or, you can order your PE amplifier with the DSP Option Card factory installed.
