2. Connection to the host and the amplifier/headphones
ADVICE: Windows users must install the driver prior to connecting the hiFace to the
PC (please refer to section 5).
ADVICE: both PC and amplifier/preamplifier should be switched off and
disconnected from the mains sockets before connecting the
hiFace DAC
.
Please refer to section 1, “Connections”.
Connect the
hiFace DAC
to the host USB 2.0 port by inserting its USB plug (Figure 1, 1)
into the host socket. If straight insertion is difficult or when in need of avoiding straight
insertion, an USB 2.0 extender cable (A male to A female) can be used. Please avoid
using extenders more than 4m, to avoid invalidating the bus performance.
If your computer has a Windows operating system and a driver hasn’t been installed prior
connecting the
hiFace DAC
, an error message may appear and you may need to
disconnect the
hiFace DAC
and install the driver (see section 5.3).
Connect the 3.5mm jack end connector of a 3.5mm jack-to-RCA interconnect to the
hiFace DAC
output connector (Figure 1, 2). Connect the RCA end of the connector to
one stereo input of a preamplifier or integrated amplifier.
A headphones set can also be driven by the
hiFace DAC
, provided its impedance is
medium or high (32 Ohms or more). In this case, connect the 3.5mm stereo jack of the
headphones to the output connectors of the
hiFace DAC
.
This can be done either before or after connecting the
hiFace DAC
to the computer: the
hiFace DAC
operation is glitchless, so no bumps or other dangerous noises will be
generated on headphones drivers.
