4.4 Main Menu
Once 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 about
the current operating state of the amplifier like for example output signal
levels, loaded presets, limiter, input and network settings, temperature
status 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-sensitive
elements to prevent unintentional changes.
– The System Info menu displays for example the amplifier serial number
and firmware release version number
Please consult the V8 Navigation Guide for details about all different men-
us, screens and options. You can always find the current V8 Navigation
Guide on our website www.camcoaudio.com.
4.5 Power Amp Protection Systems
4.5.1 Clip Limiter
If the maximum output level is langer than the amplifier can deliver, the Clip
Limiter (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 two
mono-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 responsive
and accurate. This means that you will still see the Clip LEDs light up, even
if the clip limiter is working correctly. This allowes the user still to asess if
there is real clip, even if the clip limiter does prohibit audible distortion. The
remaining (and indicated) clip is then very small and usually low enough
to be audibly perceive as "clean" or undistorted signal, compared to a
disabled clip limiter.
4.5.2 SOA Protection
To ensure that the power transistors are only used in the Safe Operation
Area (SOA), the SOA-protection would mute the corresponding channel if
not. If the power transistors are back in their SOA, the channel is automati-
cally unmuted again.
4.5.3 Thermal Protection
The microprocessor uses several sensors on the amplifier’s heatsinks in
order 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 on
that 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. The
thermal protection status of the amplifiers are indicated in the signal moni-
tor section of the display.
