4.2 Indicators
4.2.1 Output Current LEDs
The brightness is proportional to the output current in the channel. Output
current of approx. 1 A lights up the LED at its lowest brightness level, while full
brightness corresponds to the maximum rated current.
4.2.2 Signal LEDs (multifunctional)
The channels Signal LED is illuminated green when the voltage level at the
output reaches approx. 4 V; this corresponds to a power of approx. 4 W at an
impedance of 4 Ohms. The channels Signal LED is illuminated red while the Amp
is in Protect Mode (Mute).
