An ultrasonic network uncouples RF from the output and helps to keep theamplifier stable with reactive loads.OPERATING VOLTAGE (AC MAINS) - On the rear panel will indicate the correct AC mains voltage. Connecting to the wrong voltage is dangerous andmay damage the amplifier. Always be sure the source voltage for your areas matches the required voltage for your amplifier.GAIN CONTROLS - The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to adjust the amplifier sono “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion during normal operation.AMPLIFIER FEATURES:SWITCH-MODE POWER SUPPLY: The S Series amplifiers are designed with SMPS power with CLASS H (S-5000 & S-6000) and CLASS AB (S-4000) ofPower Stage Topology instead of the traditional toroidal transformer, therefore the total weight of the amplifier is ultra-light, and also the complete performance isbetter.THRU - THRU will allow the user to daisy-chain one amplifier's signal input into another amplifier. Plug the signal source outputs into the first amplifier's input,patch from the amplifier's THRU jacks to the next amplifier's input, and so on, daisy-chaining as many amplifiers as there is no excessive level loss.LED INDICATORS - Each channel has six LEDs. Four LEDs indicate signal level activity; two green LEDs and two yellow LEDs. One red LED indicatessignal clipping. One red LED indicates protections mode for shorts / overload.FUNCTION INDICATORS - These green/blue/green LED indicators detail the amplifiers current operating mode (Parallel, Stereo or Bridge).Introduction Front Panel Rear Panel Set Up Speakon Assembly Operating Modes SpecificationsProtection Features
