MDA-250

2 x 50W HIGH EFFICIENCY DIGITAL AMPLIFIER

INTRODUCTION

The Absolute Acoustics® MDA-250 is a 2-channel digital amplifier that delivers 50W of continuous power @ 8 Ohms or even more when used at lower impedance ratios. Its heart is powered by a high quality digital amplification module, valuing sound quality and unmatched robustness.

 

With enough flexibility to meet the demands of custom installations of all types, the MDA-250 is the perfect complement to the Absolute speaker line. Each channel provides 50W RMS of continuous power into 8 Ohms, or 70W RMS into 4 Ohms, more than enough to feed high quality whole-house audio systems. All this power is safeguarded by individual protection circuits for overload, short circuit and overheat, protecting the amplifier and speakers from any adversities.

 

For ease of installation, the audio source for each channel can be selected either from a global input or direct channel input. The unit can be controlled directly through the main power switch on its front panel, through a trigger input located on the rear panel or automatically, sensing the audio signal.

 

KEY FEATURES

50 REAL

WATTS


Each channel provides 50W RMS of continuous power into 8 ohms, or 70W RMS into 4 Ohms, more than enough to feed high quality whole-house audio systems.

DIGITAL AMPLIFIER

 

 

The MDA-250 uses Class-D amplification modules, operating coolly and with an efficiency of superior to 90%. They are also compact and lightweight.

UNMATCHED
SOUND QUALITY


Ultra-low distortion amplifying circuits provide clean and precise audio, even at high listening volumes.

LOOP
OUTPUTS

 

“Loop” outputs allows the transmission of the input signal to the next amplifier, making easier the integration between multiple units.

COMPACT

SIZE

 

All this technology is embedded in a compact 1U chassis, which makes the installation easier in furniture or professional racks.
