6.3.3. Status indicators (LEDs)
On the bottom left of the front panel the following status LEDs are
provided:
POWER Green: Power on status of the device.
DATA Yellow: Indicates two states:
▪ Permanent: A network cable is connected
to one of the ETHERNET (RJ 45) sockets of the
device.
▪ Flashing: A data stream is transmitted.
MUTE
Red: Mute status of the respective channel.
In addition these LEDs also acts as Error
indicators for either a channel or device error. In
the case of an error the LEDs starts flashing
according to the following flashing patterns:
Channel error: Single flash of the
corresponding Channel mute LED.
Device Error: Double flash of all Channel mute
LEDs.
Signal
LEDs
Indicates three states:
▪ Green: ISP (Input Signal Present):
Illuminates when the analog input signal
exceeds –30 dBu or when the digital input is
locked to 48 or 96 kHz and the signal
exceeds –57 dBFS.
▪ Yellow: GR (Gain Reduction):
Illuminates when one limiter reduces the signal
by a predefined level (GR ³ 3 dB)
▪ Red: OVL (Overload):
Illuminates when ...:
▪ any signal within the channel exceeds
–2 dBFS.
▪ DSP suffers from an internal EQ filter
overflow.
▪ any limiter causes a gain reduction of
12 dB or more.
▪ the output signal is limited to prevent
distortion due to output peak current
overload.
