8.2.2.5 AES Input Options
These options are available only for a Lake device with two clock domains.
▸ AUTO chooses the clock most relevant to the incoming digital signal. For example, if the input signal is
48 kHz, the Primary Clock will be selected; if the input is 44.1 kHz, the SRC Clock will be selected. The
default is Primary Clock if a digital input signal is not present.
▸ PRIMARY forces use of the Primary Clock, regardless of whether the clock rate matches the incoming
signal rate.
▸ SRC forces use of the SRC Clock, regardless of whether the clock and incoming signal rates match.
When both the Primary and SRC clocks are manually locked to
separate asynchronous base-48 kHz domains, it is important to
manually select which clock domain each AES input should lock
to. Leaving as AUTO may result in clock slipping errors.
8.2.2.6 Analog Input Options
For analog inputs, ANALOG INPUT HEADROOM (RMS) provides a two-way toggle for selecting 12 or 26
dBu. Tap the required headroom level to set the maximum RMS level for the input.
PLM+ and D Series amplier are xed to 26 dBu RMS.
8.2.2.7 Digital Gain Offset
The Digital Gain Offset represents the amount of gain increase or reduction in dB that will be applied to the
digital input signal to allow seamless transition between all input types.
As levels of digital and analog signal vary, the Digital Gain Offset can be used to adjust the digital input
signal level to match the analog input signal level.
This can be used in conjunction with AUTOSELECT to provide an automatic analog backup to the incoming
digital audio. Separate values are provided for AES and CobraNet.
To change an offset, tap the value that you wish to change and enter a new value using the on-screen (or
external) keyboard. These offsets are shown on the I/O CONFIG summary.
When aligning analog and digital signals using the
Digital Gain Offset setting, the +4 dBu Reference
meter mode should be used to ensure levels are
matched with a common internal reference.
