DiGiGrid IOS/IOS-XL / User Guide

SAMPLE RATE
sets the sample rate when Clock Source is set to Internal. Range: 44.1 / 48 / 88.2 / 96 kHz.
If the device is the network (SOE) clock master, as determined in the Device Racks of the
SoundGrid host, then this setting determines the sample rate of the SoundGrid network.
If Clock Source is set to an external clock source, you cannot change the sample rate from the
host. The Sample Rate menu is grayed out and inoperative.
CLOCK STATUS INDICATORS
Three windows on the right side of the Clock control panel help you to quickly assess the network status of the device.
When the device is a slave in the SoundGrid network, you will likely sync it to the SoundGrid network clock (via SOE).
Even when the device is an SOE slave, you can lock it to an external clock source. For example, if another SoundGrid
I/O device is the SOE master and is locked to a word clock device, you may choose to receive clock from the same
external device over word clock from the master device rather than via network SOE.
In the event that the selected clock source fails, IOS/IOS-XL has a series of clock fallback layers, in this order: WC,
Digital, SOE, Internal.
If the device is clocked to external source and that clock source fails, it will seek an alternate
source of clock, in this priority: word clock, Digital 1, Digital 2, and then SOE. If this fails, the device will fall back to
Internal.
Status
Reports the presence or absence of sync between the IOS/IOS-XL and
the SoundGrid network.
Current Clock
Source
Displays the current sync method. This may differ from the choice made
in the Source menu.
SOE
Indicates whether this IOS/IOS-XL is the master or a slave in the
SoundGrid network. This mirrors the status information in the SoundGrid
Studio Device Rack.
