McIntosh MDA5000

McIntosh MDA5000


Convertitore Digitale/Analogico HD/CD 24 bit con oversampling ottuplo, livello di uscita 3.2 Vrms CD e 6.4 Vrms HD/CD.

If you a building a superior mobile audio system the way you build a superior home audio system – one piece at a time, your digital processor will be one of you most critical decisions. The McIntosh MDA5000 can provide performance that is sonically transparent and absolutely accurate – in a word, everything you want an external D/A to give you.

The converters themselves are Selected Grade 24-bit processors – one per channel. They work with a powerful 24-bit DSP that provides both 8-times Oversampling digital filter performance as well as automatic HDCD decoding for superior dynamic range on HDCD software. The incoming data is processed by a low jitter clock recovery digital interface. This eliminates small timing errors that smear the sound and mask subtle details.

Two coaxial digital inputs and one optical digital input are available. The inputs are constantly monitored and switching is automatic. All inputs and outputs are gold-plated for corrosion resistance and better signal transfer. The unit is mounted in an extruded aluminum chassis for improved performance and reliability and features the familiar Illuminated Glass Panel that is part of the McIntosh heritage.

A modern audio system, whether in the home or in the car, depends on the performance of its digital section for much of its sound quality. The MDA5000 has HDCD decoding, advanced Selected Grade 24-bit processors, auto-switching optical and coaxial inputs, McIntosh built-quality, and those Scottish good looks. Who says beauty’s only skin deep?

HDCD® Decoder with 24 Bit 8 Times Over-Sampling Digital Filter
The MDA5000 is equipped with a powerful 24 Bit digital signal processor. This digital signal processor can provide automatic HDCD decoding and 8 times over sampling digital filter function for both CD and HDCD. The HDCD decoder provides a wider dynamic range when the HDCD disc is used.

HDCD® Indicator
The MDA5000 is equipped with a HDCD Indicator. The indicator will be lit when the HDCD Digital Audio Signal is present at input

Selected Grade 24 Bit Digital-to-Analog Converter
The MDA5000 is equipped with a selected grade 24 Bit Digital-to-Analog Converter per channel. This advanced Digital-to-Analog Converter can provide low-distortion, low-noise and high fidelity sound.

Digital Interface Receiver
The MDA5000 is equipped with a low jitter clock recovery digital interface receiver. A very clean recovered clock from the incoming signal is used in the converter to maintain the sound quality.

Two Coaxial and One Optical Digital Audio Input with Automatic Switching
The MDA5000 has two coaxial and an optical digital audio input. All inputs are monitored continuously and switched automatically.

Gold Plated Terminals
McIntosh provides gold plated input and output terminals on the MDA5000 for superior corrosion resistance.

Superior Construction
The famous McIntosh Design, an Illuminated Glass Top panel together with a Extruded Aluminum Chassis help to insure superior performance and long term reliability which is very important in the automotive environment.
