1
FireWire/ADAT configuration switch
This switch determines whether the digital interface is predominantly FireWire or ADAT and will be dependent
on what type of external equipment is used. Set to FireWire if a computer or equipment with IEEE 1394 FireWire
connection is to be used or ADAT if an ADAT machine only is to be connected. Select the switch to your de-
sired setting BEFORE switching on power to the ZED-R16 because the switch is only read on power up.
2
ADAT sample rate switch
If ADAT is selected as the digital interface, the sample rate is set using this switch to either 44.1kHz or 48kHz.
Again, select this switch to your desired setting BEFORE turning on power to the ZED-R16.
3
FireWire connectors
Standard 6 pin IEEE 1394 FireWire connectors for connecting ZED-R16 to a FireWire bus. Normally only one
connector is used, however two are provided for connecting more than one ZED-R16 together for expanded
capability. It is usually a more reliable method to connect to the FireWire bus once the ZED-R16 is powered on,
rather than switching on the power with the FireWire bus already connected.
4
MIDI OUT DIN connector
A standard 5 pin DIN connector to output the MIDI data generated by the controllers on ZED-R to external
equipment with MIDI functionality, for example when using ZED-R16 as a MIDI control surface.
The MIDI data is also sent on the FireWire bus, so there is no need to use the DIN connector if MIDI is only re-
quired in the computer and the computer is connected to ZED-R16 using FireWire.
5
ADAT In & OUT connectors
Standard ADAT optical connectors for connecting external equipment with ADAT inputs and outputs.
DIGITAL I/O CONFIGURATION:
The number of digital channels and range of sample rate options are dependent on the configuration of ZED-R16.
Here is a table of the options:
FireWire/ADAT Sw Sample Rate (kHz) FireWire Channels ADAT Channels
FireWire 44.1 & 48 18 + 18 8 + 8
FireWire 88.2 & 96 16 + 16 None
ADAT 44.1 None 16 + 16
ADAT 48 None 16 + 16
