8 Channel AES/EBU Digital Audio
Inputs And Outputs
One BNC connector is provided for both the
channel 1 and 2 inputs, similarly input channels
3/4, 5/6, and 7/8 are also each grouped on 3
additional BNCs. Another group of 4 BNCs
provides the same channel groups for AES/EBU
outputs. In order to connect equipment having AES/EBU digital audio XLR
connectors, use appropriate adapters (not supplied).
Analog 4 Channel Balanced Audio Inputs and Outputs
Eight XLRs, 4 female for input and 4 male for output, provide 4 channels of
balanced audio. Audio is high-quality 24-bit A/D input and D/A output at 48kHz.
Level adjustments are provided via software for +15/18/24 dBu (full scale digital).
Analog 2 Channel Unbalanced Audio Output
Two RCA connectors provide an unbalanced stereo audio output pair for
driving inexpensive audio monitoring systems or for connection via Y-
adapter (not provided) for use with headphones.
RS422 Machine Control
A female DB9 connector provides connection for VTRs, digital
disk recorders, and other devices using RS422 SMPTE protocol.
FireWire
IEEE 1394b FireWire™ connector for connecting to the 800 Mb/s
FireWire connector on an Apple Mac Pro or MacBook Pro for passing
data. This connector does not support connection to any other FireWire
devices such as cameras or harddrives.
AC Power
A standard male AC power socket provides connection to the
3-conductor power cable. Ensure the Io HD is plugged into a
grounded socket. The internal Io HD power supply is autosensing,
meaning that it adjusts automatically to a mains supply from 100 to
240VAC at either 50 or 60Hz. A power switch is part of the
connector, allowing easy ON/OFF control.
Warning!
The Io HD chassis has no user-serviceable parts. An internal fuse protects the
circuitry; however, it can only be replaced by AJA service centers or AJA dealers.
To remove power from the unit, remove the AC line cord to ensure disconnection.
