4. Signal Mode Settings
Three signal modes are available using USF-105DADA.
AES Distribution Mode
Inputs and distributes digital audio signals.
Inputs AES/EBU signals with sample frequencies from 32 to 96KHz.
* Gain is not adjustable using the front panel.
LTC Distribution Mode
Inputs and distributes LTC signals.
Inputs LTC signal as signal input.
Gain is adjustable using the front panel.
(Adjustable gain range: Approx. ±3.0dB)
Word Clock Distribution
Mode
Inputs and distributes Word Clock signals.
Gain is adjustable using the front panel.
(Adjustable gain range: Approx. ±3.0dB)
Sets distribution mode according to the signal input referring to illustrations in the table below. (Default:
AES distribution mode)
Sets distribution mode using DS1, DS2, S2, and S3 switches on the card. See Sec. 3
“Switch Settings”
for switch locations.
After changing the Distribution Mode
…
Outputs signal level changes according to the distribution mode. Before connecting a device, check
that the distribution mode is set correctly and the output signal level meets the equivalent level of a
connecting device to prevent damage to the device.
