LMS-D4

Introduction

The LMS-D4 is a compact and powerful DSP based audio-processing unit designed for use with particular Turbosound loudspeaker systems and associated bass enclosures, combining the functions of multiple conventional products in a compact 1U high 19” rack unit. To achieve this the LMS-D4 has 2 inputs and 4 outputs, which are configured by different system presets to allow two basic modes: stereo 2 way and mono 3 way. The unit is designed to provide specific equalisation and crossover points aimed at optimising the performance of these Turbosound loudspeaker systems. In addition, limiters, delays (up to the equivalent of 14 metres), gain, polarity, and bass trim controls are accessible to the user in order to match specific operation environments. The LMS-D4 is designed for quick setup and adjustment via easy-to-use front panel controls.

Features

•The LMS-D4 provides exceptional audio quality with carefully optimised processing and high performance converters for a full >108dB dynamic range, high sampling rate and minimal filtering. Audio-grade capacitors are used in the analogue signal path.

•Bass boost filter, allowing an easy adjustment of the response to match variations in acoustic environment such as half space operation (for floor monitor use), coupling of cabinets in arrays, or room resonances.

•Front panel rotary encoder providing a familiar and easy to use control format with all filter information displayed simultaneously on a backlit LCD display.

•Delay of up to 42mS can be set for each output (mono) or each pair of outputs (stereo).
