Additional functions
1. Status LED
The Status LED indicates the operating mode
of the amplier.
Green: Amplier is ready for operation.
Yellow / green ashing: Overheat control
is active. The overheat control dynamically
limits the output power and allows to always
achieve the maximum output power depend-
ing on the temperature.
Yellow: The amplier is overheated. The in-
ternal temperature protection shuts down the
device until it reaches a safe temperature lev-
el again.
Yellow ashing: The fuses inside the device
are blown. Please check the fuses and, if
necessary, replace them. They may only be
replaced by identically rated fuses (4 x 30 Am-
pere) to avoid damage of the amplier.
Red: A malfunction has occurred that may
have di󰀨erent root causes. The HELIX
P ONE MK2 is equipped with protection
circuits against over- and undervoltage,
short-circuit on loudspeakers and reverse
connection. Please check for connecting
failures such as short-circuits or other wrong
connections. If the amplier does not turn on
after that it is defective and has to be sent to
your local authorized dealer for repair service.
2. Clipping LED
Normally the Clipping LED is o󰀨 and only
lights up if the input stage is overdriven.
On (red): One of the signal inputs is over-
driven. Reduce the input sensitivity
using the gain control until the LED
goes out. How to reduce the input
sensitivity is described on page 16
