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.
