2 Control Elements and Connections
2.1 Front Faceplate
The front faceplate of the N8000 has level and status displays and it offers also the possibility to
connect a PC via a USB interface. SIGNAL / PEAK-LEDs exist for all 32 audio channels. The
channels are combined to groups of 8 and assigned to the audio-slots 1 to 4 at the rear.
Additional LEDs inform about the states of the network, system and device and give a quick
overview of whether the system is working faultlessly or if a problem has occurred.
SIGNAL / PEAK-LEDs
These LEDs serve as level meter display for input and
output signals. The SIGNAL-LED begins to flash at -25 dBU
and indicates if a signal generally exists at the input or at the
output. The PEAK-LED flashes when the N8000 is operated
close to the level meter’s limit. The limit is approx. at
+18 dBU. The maximum level meters is +21 dBu so that
there is 3 dB of head room until the final clip limit is reached. The PEAK-LEDs should only flare
up sporadically in case of dynamic peaks. If the PEAK-LED of an input flashes constantly or very
often, you should reduce the corresponding input signal slightly. If the PEAK-LED of an output
flashes constantly, the internal gain should be reduced or else the connected device will be
permanently overdriven.
NETWORK-LEDs
If the N8000 is operated on an audio network, e.g.
CobraNet™, these LEDs show the status of the network.
The ACTIVE-LED flashes or twinkles when audio data is
sent or received via the network. If the LED is off, no
communication via the audio network is taking place. The
MASTER-LED is on when the N8000 serves as clock-master - in case of CobraNet™ it is also
named the conductor. There is always only one master in an audio network, i.e. the MASTER-
LED will only be illuminated on one N8000 within the network. If the unit currently functioning as
