DSP In-wall Digital Active Loudspeaker User Guide

Introduction

The DSP750 is Meridian's highest performing in-wall
loudspeaker. Engineered using Meridian's core principles of
sound design, the DSP750 delivers high resolution audio that
is perfect for architectural installations and dedicated home
theatres. Optimised for use behind a screen or stretched fabric
wall-coverings, the DSP750 boasts a high dynamic range and
an exceptional signal-to-noise ratio enabling it to provide
distortion-free audio from the quietest detail to the loudest
crescendo. A beryllium tweeter with diffraction expansion
technology is one of the five drive units each of which is
powered by a pair of amplifiers capable of delivering over
100W into 8 Ohms. With a frequency response from 30Hz
to 40kHz and an output of up to 120dB at 1m, the DSP750
delivers incredible power, fidelity and accuracy for both
music and movies.
Acoustic enclosure
The DSP750 features a sealed "double-baffle" aluminium
enclosure design which minimises unwanted resonances and
colouration to ensure a reliable and repeatable performance
in every installation. The enclosure also acts as a heatsink
with huge thermal capacity for the built-in power amplifiers.
Separate mid-range driver enclosures prevent the bass drivers
from interacting with the mid-range units.
Class-M DSP engine
Phase-linear DSP crossovers with text-book performance ensure
the drive-units remain in phase with each other across their
crossover regions. The DSP engine also provides thermal and
dynamic bass protection while retaining very accurate transients,
ensuring that when the loudspeaker is played at high levels –
even over prolonged periods of time – it always delivers a clean,
detailed and accurate sound.
