Behavior with Defective Input Signal
The behavior in the event of a defective input signal can be influenced using the On Loss
Of Input
 switch:
– Mute: The output signal of the transmitter is suppressed as soon as synchronization with
the input signal (from the operating input and standby input) is no longer possible.
– No Mute: The output signal of the transmitter is not suppressed even though the input
signal is defective. However, when this happens only null packets are transmitted.

Input Amplitude
Nominal input amplitude
At the nominal input amplitude, a nominal signal with 30% S and 70% noncomposite com-
ponents is assumed. All of the percent indications which follow with reference to the ampli-
tude relate to the selected input amplitude and a nominal signal.

Clipping
Indicates the status of input signal clipping; the indications are as fol-
lows:
– No status display: Input signal is within the valid range (NO CLIP-
PING)
– Yellow: Input signal is just off a limit boundary (NO HEADROOM)
– Red: Input signal is limited (CLIPPING)
