Powersoft KDSP Board

State-of-the-art sound shaping under your fingertips!

All K Series amplifiers can be factory-equipped with KDSP, or be retrofitted later.

The KDSP board provides access to unique Armonia Pro Audio Suite functionalities such as LiveImpedance Measurement, TruePower Limiter, and Active DampingControl.

Programming/editing can be achieved both via the amplifier front panel and via Ethernet with the Armonia Pro Audio Suite software.

Processing power and audio performances
Based on Analog Devices SHARC DSP with 40 bit floating point data allowing for optimal dynamic range and lossless processing, the KDSP board offers:

2x analog input with:
• Tandem technology for optimized A/D conversion (>125dB SNR)
• Up to 4s of input delay
• Arbitrary frequency response input equalizer with three layers of 32 filters each (PEQ, Raised cosine, Shelving)

Complete set of limiters: RMS, TruePower and Peak limiter with look ahead, to protect drivers from excessive power and potentially breaking displacement.

2x fully processed outputs with:
• 8 biquad crossovers (up to 48 dB/octave)
• 16 full parametric filters per channel (Peaking, High/Low Shelving, High/Low Pass Eq, Band pass, Band stop, All pass)
• Custom FIR filter (385 taps @ 48 kHz or 96 kHz for the pre-output eq and for each output eq)
• 100ms delay available for alignment/auxiliary purposes

Control and monitoring features
The KDSP board is fully supported by Powersoft Armonia Pro Audio Suite software allowing full access to unique features:

• Active DampingControl, for dramatically improved cone control resulting in better sound and higher output
• TruePower Limiter to avoid burning voice coils while getting maximum performances
• LiveImpedance Measurement for load impedance monitoring during live performances, using 8 analog audio inputs for output current and voltage acquisition.
