but not to both at the same time. If you like to record
from both inputs simultaneously, please make sure that
all devices that are not used as clock source are
synchronized by means of the UC1 word clock or AES
outputs.
In case you use the UC1 without a computer connected
to the back USB, it will become a multi-input DAC and
you can choose to let the clock source switch
automatically with the selected audio source. Please
read the menu chapter, paragraph ‘F2’, for instructions.
On the front
A unique feature of the UC1 is its front USB input, the ‘i-
put’. It is intended to connect a secondary stereo USB
source such as a laptop or smart device to the UC1 and
your DAW. Smart devices are often connected wireless
to a computer. The advantage in using the i-put with a
smart device is that in contrast with wireless
connections all sample rates and bit depths are
supported and data is transferred bit transparent. It
may also offer you a more reliable connection.
To use the USB front i-put, please note these two
important instructions:
1. The UC1 sample rate cannot be controlled from the
front USB. As a result the UC1 can only play audio from
the front USB input if the playback sample rate of the
device is the same as the current UC1 sample rate.
2. If you like to connect an Apple smart device such as
an iPhone or iPad, a special conversion cable called
“Lightning to USB3 camera adapter cable” or “USB-C to
USB adapter cable” (depending on your device) is
needed. These cables carry a chip that enables audio
playback to USB from iOS devices. Some cables also
provide a means to power the iDevice externally.
For the rest, the front USB behaves like that on the back:
on Mac OS, Linux, Windows 10, iOS and Android you do
not need a driver. We supply a driver for Windows that
offers more options.
The front analog input is a stereo unbalanced 6.3mm
jack with a gain control next to it. It can be used for
4.
