VORTEXS I LV E R SE R I ESUSER MANUALVORTEX SILVER SERIES V8P.194.4 Main MenuOnce that amplifier has been turned on, the main menu offers six items:– The Power menu is used for switching the amplifier off.– The Settings menu offers control of all important amplifier settings.– The Monitor menu gathers different screens carrying information aboutthe current operating state of the amplifier like for example output signallevels, loaded presets, limiter, input and network settings, temperaturestatus and more.– The Display menu offers control of the display brightness and contrast,allows to define the Home and Quick Access Menus and more.– The Lock Device menu allows to temporarily disable the touch-sensitiveelements to prevent unintentional changes.– The System Info menu displays for example the amplifier serial numberand firmware release version numberPlease consult the V8 Navigation Guide for details about all different men-us, screens and options. You can always find the current V8 NavigationGuide on our website www.camcoaudio.com.4.5 Power Amp Protection Systems4.5.1 Clip LimiterIf the maximum output level is langer than the amplifier can deliver, the ClipLimiter (if active) will reduce the output signal in order to limit distortion.The clip limiter algorithm works in a forward driven and clip signal depend-ent approach.The Clip Limiter works on each channel independently (except for the twomono-operation modes). The Clip Limiter has three different modes (Off,Slow and Fast) which can be selected in the settings menu.The Clip LED sensitivity on the display is designed to be very responsiveand accurate. This means that you will still see the Clip LEDs light up, evenif the clip limiter is working correctly. This allowes the user still to asess ifthere is real clip, even if the clip limiter does prohibit audible distortion. Theremaining (and indicated) clip is then very small and usually low enoughto be audibly perceive as "clean" or undistorted signal, compared to adisabled clip limiter.4.5.2 SOA ProtectionTo ensure that the power transistors are only used in the Safe OperationArea (SOA), the SOA-protection would mute the corresponding channel ifnot. If the power transistors are back in their SOA, the channel is automati-cally unmuted again.4.5.3 Thermal ProtectionThe microprocessor uses several sensors on the amplifier’s heatsinks inorder to ascertain temperature data. If the microprocessor detects a tem-perature of more than 85 °C at the amplifier’s heat sinks, the input signal onthat channel is automatically reduced. If the temperature exceeds 95 °C,the corresponding channel is muted. If the temperature exceeds approx.100 °C, the main SMPS is switched off as an emergency protection. Thethermal protection status of the amplifiers are indicated in the signal moni-tor section of the display.4 OPERATION
