INTRODUCTION AMPLIFIER DESCRIPTION General information Thank you for purchasing D.A.S. Audio S.A. products. This unit represents 30 year of expertise in transducer and enclosure design, achieving a system that utilises the most advanced sound reinforcement technology to deliver outstanding audio performance and maximum reliability. This manual contains the required information to make the best use of the system you have purchased. Please take the time to read it. Our WEB (www.dasaudio.
USE Preliminary This product should only be used in E1, E2, E3 or E4(*) environments, in accordance with standard EN55103-2 (Electromagnetic compatibility. Product family standard for audio, video, audio-visual and entertainment lighting control apparatus for professional use. Part 2: Immunity.) Do not cover the amplifier's radiator nor obstruct its ventilation (except for the rain protector supplied by DAS).
CONNECTIONS LINK LINK LINK LINK LINK LINK Self-powered systems connection The illustration below show a typical diagram for connecting this system to other powered units. In this four-way configuration and the sub-bass frequencies are handled by LX-218A units while the low, medium and high frequencies are handled by aero 38A units. An external processor is required to time-align the sub-bass and low frequencies by adding delays. Additional equalization or filtering are not required.
Pasive systems connection In this other four-way configuration, besides introducing delays, the external processor has to process the signal and distribute it amongst the other external amplifiers, with the correct equalization. (Check the factory recommendations for aero 38 or aero 48 units.
TROUBLESHOOTING PROBLEM CAUSE No sound from the unit. The SIGNAL presence LED indicator(s) do(es) not light up. SOLUTION 1 – The signal source is sending no signal. 1 – Check that the mixer or sound source is sending signal to the UNIT. 2 – Defective cable. 2 – Check that the cable from the sound source to the UNIT is connected correctly.

APPENDIX: Line connections: unbalanced and balanced There are two basic ways to transport an audio signal with microphone or line level: Unbalanced line: Utilising a two conductor cable, it transports the signal as the voltage between them. Electromagnetic interference can get added to the signal as undesired noise. Connectors that carry unbalanced signals have two pins, such as RCA (Phono) and ¼” (6.35mm, often referred to as jack) mono.
