INSTALLATION & OPERATION

Background

In-wall loudspeakers are not a new invention. Indeed they have been employed for many years by installers who wish to provide an unobtrusive audio solution to customers who have been unwilling or unable to install conventional free- standing loudspeakers.

However, the design restraints generally imposed on an in-wall design – limited space and thus limited enclosure volume, physical limitations on materials and other restrictions – have meant that in-walls have traditionally offered a level of quality and performance that has lagged some distance behind their free-standing counterparts.

Meridian’s DSP420 breaks that mould with an in-wall loudspeaker that is a cut above the rest. Inside each unit, Meridian’s unique high technology digital signal processing is used to free the sound from the walls: the result is clear and open with a wide response, very much in line with the performance of Meridian’s smaller free-standing DSP-based loudspeaker models,

The DSP420 accepts up to 96kHz/ 24-bit inputs including Meridian MHR Smart Link. The M420 accepts line-level balanced analogue inputs. Unit is designed to comply fully

with international building regulations

and with a similar character, enabling in-wall and free-standing speakers to be combined in a single system as required.

As a result, the DSP420 has become one of Meridian’s most popular loudspeakers. Following its success, and in response to customer demand, an active analogue variant, the M420, is now available, with the same bass drivers and power amplifiers as the DSP version. In addition, the back-box available for both units has been redesigned to permit easier and quicker installation, including BNC connectors on the digital version and XLRs on the analogue.

Truly Active In-Walls

The DSP420 and M420 are truly active in-wall speakers with separate internal amplification for high and low frequency bands. Rated

at 65 and 85 Watts respectively and using carefully selected bipolar output devices, the idealised low feedback designs are based on those used in other Meridian loudspeakers to deliver exceptionally fast bass response and
