SILVER Audio Processor 4Bmini metering
The SILVER Audio Processor 4Bmini metering is accessible at any time by pressing the middle soft key on the front
panel. It shows instant IO meters as well as all processing metering.
I/O metering
The input meters show the level of the input audio. The meters are ‘hooked in’ to the DSP code after the input level
selection and mode options.
The output meters represent the level in dB below full scale output. This output level is the peak output level of
the processing and has nothing to do with the actual output level set by the analogue and digital output level options.
The output meters show a smaller dynamic range compared to the input ones. This reflects the smaller dynamic
range of the audio once processed by the SILVER Audio Processor 4Bmini. If we were to have used the same scale
as the input metering we would not see a lot of activity on the bars.
The multiplex output metering represents the composite outputs peak level. This is a representation of the output
in relation to the peak composite level of the processing and not the actual level set by the multiplex output
level control.
The IO meters follows an approximation of the PPM level of the audio waveform.
Multi-band AGC
The first four gain reduction meters show the gain reduction of the multi-band AGC. The range shown is -21dB
to +21dB in dB steps.
There is only one meter per stereo channel and the value shown is the largest gain reduction of the left and right
channels. Under normal operation (with a stereo audio feed) this is fine but you may observe strange metering if
the channels are not very balanced in level.
Multi-band limiter
The second four gain reduction meters show the gain reduction of the multi-band limiter. The range shown is
0dB to -1 dB in 1dB steps.
There is only one meter per stereo channel and the value shown is the largest gain reduction of the left and right
channels. Under normal operation (with a stereo audio feed) this is fine but you may observe strange metering if
the channels are not very balanced in level.
STATUS LEDS
The SILVER Audio Processor 4Bmini front panel contains three status LEDS.
REMOTE: Indicates that the SILVER Audio Processor 4Bmini is currently talking to a remote computer. This will flash
during
an update of the firmware or remote control with the remote control application.
AES/EBU: Indicates the presence of a valid AES/EBU signal connected to the digital audio input of the
SILVER Audio Processor 4Bmini.
EDIT: Indicates that you are currently editing a parameter
