4.2.4. OVL LED (A/B) - Overload (red) [7]:
- Illuminates depending on the input signal ⇒ Overload:
either the input signal level is too high or the D12 is trying to deliver
too high an output current. If in doubt reduce the input gain at the
D12 level control. If the error message disappears, the output current
has been too high (load impedance too low caused by too many
loudspeakers connected to the D12 output, or a defective cable or
connector). If the condition does not change, the input signal to the
D12 is too high (greater than +25 dBu).
An overload could also be caused by accumulating the source input
A+B or by high gain settings (boosts) in the single EQ bands, while
the input signal is lower than +25 dBu.
- Flashes (1:1 mark space) ⇒ Error: an error message will be
displayed altering with the device name.
