The Samson SXD Series stereo power amplifiers have been designed to provide robust, clean output with low distortion and
wide dynamic range, along with the dependability demanded by professional front-of-house engineers and installers.
The convenient two rack-space design is compact, and yet there’s plenty of power available, with 2 x 450 Watts at 4Ω for
the SXD3000, 2 x 750 Watts at 4Ω for the SXD5000, and 2 x 1000 Watts at 4Ω for the SXD7000 over the full frequency
spectrum, from 20 Hz to 20 kHz.
The SXD has a full-featured DSP and front panel LCD display with settings for high- and low-pass filters, three-band equal-
izer, output limiter, delay time for speaker alignment, and digital pass-code security lock to ensure settings are not changed
accidentally. There are also four presets designed for typical speaker configurations. These presets will allow you to quickly
get up and running with your system by displaying the parameters that are essential to the speaker arrangement.
Input connections are made via both balanced XLR and balanced ¼” TRS connections. For the outputs, the SXD Series
provides standard binding posts as well as a Speakon® connectors. To help you set the correct operating levels, the SXD
amplifiers include front panel Signal, Output Level, Limiter and Protection LED indicators.
Like all Samson power amplifiers, the SXD Series' internal electronics are based around a serious power-core, with over-
sized toroidal transformers and large heat sinks. To keep the SXD amplifiers running cool, the design employs forced-air
cooling via a temperature-sensitive, variable speed fan, which greatly reduces the chance of thermal and overheating prob-
lems. Multi-stage protection for power-up, over-heating, over-current, short circuit, low output impedance and DC voltage,
assures high reliability under the most demanding situations.
The SXD amps are designed for the rigors of either portable PA system or a fixed installation system with all-steel chassis,
19-inch rack mount design, and convenient carry handles.
Optimized for live sound venues, houses of worship, commercial installations, and for driving live PA systems, the SXD
amplifiers will deliver reliable power from gig-to-gig and venue-to-venue. In the following pages, you’ll find a detailed
description of the many features of the SXD Series power amplifier, as well as a guided tour through its front and rear pan-
els, step-by-step instructions for its setup and use, and full specifications.
