Description

RCA version:
Input Clip Level (dBu)

Timeout
(Stream-In/Out)

Value

This setting defines the period of time the
signal has to be below the threshold level
before the audio alarm is flagged.

Analog Configuration – Low Latency Mode

This “Low Latency Mode” effects the

analog

signal processing and improves the system

latency by approx. -1.5

ms. This mode disables and bypasses the

input

Sample Rate

Converter which is obsolete in these modes (Stream-In only):

Linear PCM at F

= 48

kHz (any linear PCM mode that uses 48

kHz Sample Frequency)

Note: This latency improvement takes place on audio formats (as listed above) that run
at 48

kHz sampling frequency. Whenever another mode is selected, e.g. Linear PCM with

up to 15

kHz frequency response (equals F

= 32kHz) then this mode is automatically

deactivated regardless of the enable/disable status on this configuration page. As long
