1. power of the system SPEAKER OUTPUTS The two Speakon connectors allow you to connect the amp to your favorite cabinets The connectors are wired in parallel so it doesn t matter which one to use when only connecting one cabinet Minimum permissible speaker load is 2 ohms which means that you could connect any combination of speakers as below e One 4 ohms cabinet e Two 4 ohms cabinets e One 4 ohms cabinet and two 8 ohms cabinets e A total of four 8 ohms cabinets Also higher impedance cabinets work well such as only one 8 ohms cabinet The output power will however be lower in this case REAR PANEL POWERAMP The internal poweramp is of MOSFET design giving natural sound reproduction and high power output with exceptional clarity The incorporated soft clip system provides tube alike distortion characteristics protects the power amp from saturation and increases its output performance and sound quality The poweramp makes possible maximum continuous power output reducing the maximum temperature of the unit by the use of a temperature controlled active cooling system Note that you may run the Classic 500 without any speaker load No damage will be done to the amplifier whatsoever IMPORTANT Make sure not to cover the fan or the ventilation holes on the amp U EBS will not take responsibility for eventual hearing damages caused by the powerful Classic 5002.
