1.4.1 Phase LED
Especially with high end audio components, which are by nature very sensitive to mains hum,
it is important to connect the mains phase correctly. The device is equipped with a Phase LED
(38)
on the rear panel for this purpose.
To check the phase, switch on the unit with the power button (1) and have a look at the Phase
LED (38). This LED only lights up if the mains plug is connected with the
in
correct polarity and
remains dark if the polarity is correct. The display has been deliberately designed in this way,
as the control electronics of the Phase LED (38) produces slight interference when the LED is
lit. This is not the case with correct mains polarity (and a dark LED).
1.5 Mains phase indicator
Especially with high-end audio components, which are by nature very sensitive to mains hum,
it is important to connect the mains phase correctly. The device is equipped with a Phase LED
(38)
on the rear panel for this purpose. To check the mains phase, switch on the unit with the
on/off button (1) and take a look at the phase LED (38). This LED remains dark if the polarity is
correct and
only lights up if the mains plug is incorrectly polarized
. In this case, switch the
device to standby, pull the mains plug and plug it into the socket turned by 180°.
The mains phase indicator has been deliberately designed in this way, as the control electronics
of the phase LED (38) produce slight interference when the LED is lit. This is not the case with
correct mains polarity (and a dark LED).
1.6 Connection to a preamplifier or integrated amplifier
Connect the analogue outputs (16-19) to the high-level inputs of a preamplifier or integrated
amplifier. The RCA outputs and the balanced XLR outputs are fully decoupled from each other
and may be used independently. If possible, we recommend a balanced connection via the
XLR outputs (16, 17), especially for longer connection lengths. Unbalanced RCA cables also
offer excellent sound quality, provided you use a sufficiently shielded cable of high quality.
1.7 Connection of digital sources
Digital sources
Connect digital sources to the optical (23, 24) or coaxial (25, 26) digital inputs, to the
AES/EBU digital input (27) (or to the USB digital input (22) using a suitable cable.
Digital recording devices
If you want to record digitally, you can connect your recording devices (computer, CD recorder)
to the digital outputs (20, 21). Depending on the selected source, the output carries the signal
of the internal CD player, or e.g.,
DIG COAX, DIG OPT . Please note, however, that Incoming
signals via the USB-B input (22) are not looped through the digital outputs (20, 21).
