Introduction - EAW SMS4124 Instruction Manual

2. INTRODUCTION

Congratulations on the purchase of your new EAW Commercial loudspeaker. You now
own one of the fi nest professional audio products available – the result of exceptional
engineering and meticulous craftsmanship. Please read these instructions to get the
maximum performance from your new loudspeaker.
Each EAW Commercial loudspeaker is intended for professional use. The construction,
components, and hardware have been designed to provide robust, reliable performance for
its intended application. Please ensure that you fully understand its proper installation and
operation before use.
This manual describes the SMS4990, SMS4940 and SMS4124 loudspeakers and the
optional clip-fi t mounting system. Each loudspeaker is an economical solution for exceptional
fi delity in speech reinforcement and background music applications. They are especially
suited for small to mid-sized spaces with excessive reverberation or problematic sound
refl ections. The drivers and system voicing are designed to maximize vocal range clarity and
speech intelligibility, without compromising the broadband frequency response required for
pleasing music reproduction. The included U bracket allows setting the enclosure's angle for
wall-mounting.
Each loudspeaker has four 4 inch woofers confi gured in a precise arrangement. The
SMS4990 uses one 1.3" dome tweeter, and has a 90˚ x 90˚ coverage pattern. The SMS4124
and SMS4940 use three 2" cone tweeters, and have a 120˚ x 40˚ and 90˚ x 40˚ coverage
pattern respectively. Apart from this difference, the operation and details of the loudspeakers
are identical, and this manual covers all three models.
Two optional "clip-fi t" mounting brackets are available that allow the loudspeaker to
be easily clipped in place and adjusted within a wide range of angles. The CF-4TX bracket
includes an internal transformer for constant voltage applications, and the CF-4LZ bracket is
used for constant impedance applications.
