The Display menu allows the user to monitor the system
status and performance.
11 : 1.Display: Output meters
The output meters screen shows important output sig-
nal information for the amplifier.
By pressing the right most front panel button, the screen
view is toggled between information relative to channel 1,
channel 2 or relative to the sum of channels 1 and 2.
11 : 3.Display: Mains meters
This screen displays the updated mains RMS voltage
and RMS current levels. Values are displayed in numbers
and as progress bars.
The current and voltage levels displayed in this screen
are approximate values: which serve the purpose of giving a
general indication of the mains levels. Please refer to other
sources (such as calibrated multimeters) for reliable and
exact mains voltage and current measurements.
The top line in this screen displays the RMS voltage
value of the output, both as a number as well as a horizontal
meter bar. The second and third line display the output RMS
current and power level respectively. The output power re-
ported is a peak value reading taken every 200 ms.
In the “C1+2” mode, the RMS voltage and power read-
ings displayed are the average RMS voltage and peak
power of each channel. The RMS current value, on the other
hand, is the sum of each single channel’s RMS current level.
The bottom line of the screen displays the load im-
pedance as Zload. The minimum output voltage is stored
internally and available to remote clients connected to the
amplifier.
The load impedance is indirectly inferred by a succes-
sive approximations. Time between single output imped-
ance approximations depends on the output signal: the
greater the amplitude of the signal, the shorter the time
interval between measurements needed to approximate the
output impedance, the faster the successive approximation
method will converge to the true impedance value.
11 : 2.Display: Temperature
This screen displays the current amplifier temperature.
11 : 4.Display: Amplifier name
The Amplifier Name menu gives access to two menu
branches: the “Display amp data” function and the “Edit
amplifier name” menu.
When the “Display Amp data” function is activated, the
main amplifier screen shows the amplifier name (20 charac-
ters, bold) blinking to a second screen showing the current
selected preset name (40 characters). If the preset has been
altered in any way, the displayed preset name will have a
“Modified” prefix to indicate this.
The amplifier name can be assigned by entering the
“Edit amplifier name” menu.
