Introduction - Niles SWA-500M Installation Manual

INTRODUCTION

Bass or low frequency effect (LFE) is a critical part of a well designed audio/video system. The
Niles SWA-500M is a highly efficient Class D amplifier designed specifically for up to two passive
(non-powered) subwoofers. When combined with high quality subwoofers, the SWA-500M will
provide excellent bass reinforcement for home theater and home audio applications. Installing
the right amplifier for your subwoofer(s) will give you that thunderous, accurate bass that makes
movies and music so enjoyable.
The SWA-500M uses the latest Class D technology. Class D amplifiers are beautifully efficient so
you'll get a lot more power with less current. Less input current reduces power supply size and
generates less waste heat. This process allows Class D amps like the SWA-500M to produce more
power than amps of larger size. As you read this manual and become more familiar with the
SWA-500M and Class D technology, you'll understand why Niles products are unequaled.
