MD-4 DSP Amplifier
Housed in a matching anodized aluminum enclosure, the MD-4, is a hand-built globally
adaptable 2-input/4-output ADC/DAC+DSP high-capacitance class-D amplifier with
balanced analog XLR and 192 kHZ PCM SPDIF< AES/EBU and USB streamer inputs.
The amplifier’s power factor correction linear power supply ensures universally
adaptable and fully regulated AC mains operation everywhere in the world.
Free of a high frequency damping network, the amplifier delivers full power all the way
up to 20 Hz while the extremely high voltage rail to RMS power rating ratio delivers up to
250W RMS with ultra short bursts of 500 W to 1 kW of power, providing 26 dB of gain with
a signal to noise ratio of 119 dB and 0.05% total harmonic distortion.
The amplifier’s exceptional 93% Class-D efficiency ensures minimal cooling
requirements and maximum long-term reliability.
For improved imaging and to meet the current draw requirements of even the most
demanding program material, the amplifier includes two supplementary dual high-
capacitance dynamic power reserves.
An advanced DSP engine for speaker calibration with visual programming interface via
Snowbird Audioweaver offers a total of 140 parametric filters with 60 dB better signal to
noise ratio performance than normal filters.
Filters may be used for a variety of DSP applications such as equalization, crossovers,
delays, compression, limiting, and user specific configurations.
The dedicated Digital Signal Processing engine is based on the 4th generation of Analog
Device’s 32/40-bit IEEE floating point SHARC Processor with 640-bit product and 80-bit
accumulations implements a “Super” Harvard Architecture to balance DS core and
memory performance with dedicated program and data busses.
Dedicated I/O processor and busses running at 450 MHz turns 277,700 MFLOPS to satisfy
the most demanding single-cycle computationally intensive tasks.
To avoid sacrificing as much as 15 dB of ADC and DAC performance, the MD-4 DSP-
amplifier incorporates Asahi Kasei Microdevices (AKM) VERITA Velvet Sound converter
technology.
