4.4.8.2 Solo Button
The Solo button allows any active input channel to be isolated. This
allows very rapid comparison of sources, A/B switching, and a
convenient way for troubleshooting audio anomalies.
Simply press the Solo button and it will engage and turn green with
the word “Solo” blinking.
In this state, press any input source button and you will hear that
audio exclusively. Pressing any other input source will instantly
switch to the alternate source.
When done, tapping the Solo button returns Hilo to the previous state, where multiple input sources can stream to
an output simultaneously.
4.4.8.3 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 Thunderbolt 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, Hilo TBT Play 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.
If a valid ADAT lightpipe signal is detected on the
optical input, then the ADAT inputs are visible and
available in stereo pairs.
