2.3.7 Gate CH1 - CH2
This function allows to mute the amplifier channels individually if input signal amplitude is falling below the values shown in
the following table. You can enable/disable it by pushing the on/off button. Gating the output is delayed by 5 seconds after
input signal removal, and follows in reversed way the bottom green LED on the CH1, CH2 bar LED display *(muted if green
LED is off).
2.3.12 Bar meters
In the Bar meters screen you can choose if the LED bars operate as output voltage meter and LCD bar in the main screen
as output current meter (by selecting "LED Volt, LCD Curr), or viceversa (by selecting the other item).
2.3.13 Output meters
In the Output meters screen you can view the values of the output signal for CH1 and CH2. Furthermore, the impedance of
the load is showed in the bottom line of the screen (see figure 2.3.9). Minimum of output voltage for impedance
measurements is 10Vrms, measurements values are stored into logbook. Time between single impedance measurements
can be up to several minutes depending on program signal. Output power is shown as maximum value every 200 mS.

2.3.9 Idle Mode
The idle mode function is a power saving feature. By activating it, if the amplifier doesn't detect the signal for the user
defined amount of time, the output stage is turned off, saving about 40 W of power per channel. This means reduced
heating, longer amplifier and fans life, and, especially for fixed installation permanently turned on, a lower electricity bill.
2.3.8 Mute at power on
If enabled, the amplifier will be always in mute state for both channels at power on; you can mute off the channels
independently in the main screen, but in this mode the amplifier will be in the mute state at the next power on.
2.3.10 DSP Settings
This sections is implemented if optional DSP board is present.
2.3.11 Ethernet Settings
This sections is implemented if optional Ethernet board is present.
In "C1+2" mode the screen shows the output values in bridge connection.
