Protection LEDs. In these pages, you’ll find a detailed description of the features of the S500, as well as a description of its front and rear panels, step-by-step instructions for its setup and use, and full specifications. You’ll also find a warranty card enclosed—please don’t forget to fill it out and mail it in so that you can receive online...
• User-resettable circuit breaker for fast, easy startup following a power supply overload. • The S500 can be mounted in any standard 19" rack (taking just two rack spaces), making it easy to integrate the into any fixed or traveling PA rig.
2: Power LED - Lights whenever the S500 is powered on. 3: Protection LED - This goes on for approximately five seconds whenever the S500 is powered on and then turns off (you’ll hear a “click” when it does so). The Protection LED will also light when overheating or other severe problems occur (see page 6 in this manual for more information).
Make sure that both the front and rear panels are kept free of all obstructions and that cool, fresh air is accessible at all times. Also, try to ensure that the S500 is used in a dust-free environ- ment.
PROTECTION LED will go off (you’ll hear a click when this occurs). 7. Apply an input signal to the S500 at or about 0 dBu (if sending signal from a mixer, Protection LED drive the output meters at approximately 0 vu). While the input signal is present, slowly raise the Channel Input controls until the desired sound level is achieved.
• Shorted speaker cables: This will occur if, due to faulty wiring, the hot and ground signals being output by the S500 short one another. • Output impedance drops below 2 ohms: This can occur if the S500 is con- nected to inappropriate speaker systems (see the “Setting Up and Using Your S500”...
Bridged and Parallel Modes The S500 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 S500 functions as a true stereo amplifier, where both of...
S500 Connections The illustrations on these two pages show the required interconnections when using the S500 in Stereo, Bridged and Parallel modes. Wiring for Speakon™ connectors (shown on the right) is indicated where appropriate. Stereo Mode: (two or four speakers)
