3.4.8.3 Input Sources
This is for signals from the Analog Line In ports.
Of the three stereo digital formats: AES, SPDIF Coax and SPDIF Optical, only one can be active
at a time. This is selected from the “Digital In Source” button from the Home menu.
These sources correspond to USB play devices that will appear in the host computer. Unlike
most computer audio interfaces, with Hilo these sources are user routable for maximum
flexibility.
Upon installation, each pair of computer play devices will be pre-assigned to physical outputs on
Hilo. In addition, the first channel pair, USB 1+2, will deliver audio to every output on Hilo.
This is very useful for initial set up, whether you are listening to the headphone out, a digital out,
monitor outs, whatever – you will get audio when you choose 1+2 as the play device.
When Hilo is in 8-
channel LT-USB Mode,
USB channels 1-8 are
visible and available.
When the 16-channel USB Mode
is engaged, all 16 USB input and
output channels are visible and
available.
If a valid ADAT lightpipe signal is detected on the optical
input, then the ADAT inputs are visible and available in
stereo pairs.
The Default USB play routings are:
Line Out: USB 1+2
Monitor Out: USB 1+2 and 3+4
Phones: USB 1+2 and 5+6
Digital Out XLR (AES): USB 1+2 and 7+8
Digital Out Coax: USB 1+2 and 11+12
Digital Out Optical: USB 1+2 and 9+10
ADAT Out 1-8: USB 1+2 and 9-16 (when Hilo is in 16-channel mode)
