Introduction We know you don’t like reading owners manuals, but you’ve just purchased one of the finest sound reinforcement power amplifiers around, and we want to tell you about it! So, before you plug in, we’d like to suggest you take just a few moments out to scan these pages. We’ll make it as painless as possible, we promise—and, who knows, you might just pick up a tip or two.
S1500 / S2000 Features The Samson S1500 / S2000 power amplifier utilizes the latest technology in professional power amplifier design. Here are some of its main features: • Power to spare - In the S1500, each channel delivers 750 watts of power into 4 ohms. In the S2000, each channel delivers 1000 watts of power into 4 ohms. • A Bridged mode links both channels, thus providing additional power (1500 watts into 8 ohms in the case of the S1500; 2000 watts into 8 ohms in the case of the S2000).

Setting Up and Using Your S1500 / S2000 Setting up your S1500 / S2000 is a simple procedure which takes only a few minutes: 1. Remove all packing materials (save them in case of need for future service) and decide where the amplifier is to be physically placed—it can be used free-standing or mounted in a standard 19" rack, requiring only three rack spaces.
The S1500 / S2000 Protection Circuitry PROTECTION As noted in the “Guided Tour” section of this manual, the S1500 / S2000 frontpanel Protection LED indicates the activity of the relay speaker connection circuitry. When the Protection LED is lit, this circuitry is active, and all connected speakers are muted (provided with 0 volts DC), thus protecting them and preventing any audible “thump” from occurring.
Bridged and Parallel Modes The S1500 / S2000 provides a rear-panel switch that allows it to be used in either a Bridged or Parallel mode. When this switch is placed in the “STEREO” (center) position, the S1500 / S2000 functions as a true stereo amplifier, where both of the two independent amplifier channels (Channel 1 and Channel 2) can receive different input signals and produce independent output signals.
S1500 / S2000 Connections + SPEAKON™ The illustrations on these two pages show the required interconnections when using the S1500 / S2000 in Stereo, Bridged and Parallel modes. Wiring for Speakon™ connectors (shown on the right) is indicated where appropriate.
