PROTECT LED The red Protect LED lights when one of the power amplifiers extensive protection functions against thermal overload HF induction DC at the outputs and SOAR protection is activated When the PowerMix 1 is in protect mode the speaker outputs are muted and the inputs of the power amplifier are short circuited to prevent the amplifiers from being damaged In this case you should first check if the frontal and or rear ventilation louvers are blocked Another cause for the activation of the protect functions might be that you have connected more than two 8 Ohms speaker systems per power output Please also disconnect the SPEAKON connectors and check the speaker cables for short circuit During the power on operation the PROTECT LED always lights for about two seconds This is normal It indicates that the PowerMix s protection circuitry is operational 28 POWER LED The blue Power LED lights when the PowerMix is turned on If after switching the PowerMix on the LED does not light make sure that the mains plug is plugged in correctly If the LED still doesn t light up please contact your DAP Audio dealer 29 30 UP DOWN FX1 The UP DOWN kevs let you step through the effect programs one by one in increasing or declining order Keeping either one button pressed for a longer period of time allows scrolling the effect program numbers with increased tempo 31 32 UP DOWN FX1 33 FX 1 You can change the FX value The range
