Introduction

The DSP420 In-Wall Loudspeaker System

The DSP420 In-Wall Loudspeaker System incorporates
the result of several years of research and development
into innovative technologies .
Meridian DSP
The DSP420 accepts digital input signals up to
96kHz/24-bit, including Meridian High Resolution
(MHR) streams from Meridian surround controllers,
processors, and DVD players.
Enclosed in a fully shielded housing, Meridian's
unique DSP processing is performed on a specifically
designed six-layer PCB using a powerful 100 MIPS
Motorola DSP engine. Through this sophisticated audio
computer the DSP420 receives all of the same high
technology features that can be found throughout the
Meridian DSP loudspeaker family.
These include:
• FIFO memory buffer input for the lowest possible
jitter.
• Linear-phase crossover for precision drive unit
integration.
• Tweeter delay for perfect driver alignment.
• 48-bit resolution volume control.
• Minimal frequency equalisation to give a frequency
response free from drive unit or electronic coloration.
• Transparent tone controls.
• Absolute phase control and phase-corrected balance
control.
A further DSP enabled enhancement to the audio
performance of the DSP420 is Meridian's active
bass extension. This deepens the response of the
system without excessive woofer excursion and in turn
