Quick-start guide:
1. Connect the audio signal from the source to Arche, using the digital (USB, TOSLINK) or analogue inputs.
2. Connect Arche to an earthed socket using the power cable supplied. Arche is compatible with an
alternating current operating range of between 85 and 265 V.
3. Switch on the audio source and check that the output level of the audio source connected to Arche is
set to 0dB or its maximum output level.
5. Switch on Arche.
6. Connect a set of headphones to one of the outputs on the front (1/4" - 6.35mm stereo jack or 4-pin XLR
jack).
7. Increase Arche's output level until you reach the required volume.
8. Once you have finished your session, we recommend switching off the equipment in the following order:
a. Switch off Arche.
b. Switch off the audio sources.
Arche
ATTENTION :
The amplifier part of Arche is not suitable for electrostatic headphones.
Arche is a digital-to-analog audio converter as well as a headphone amplifier. The digital-to-analog
converter is compatible with sampling frequencies of up to PCM 32 bit/384kHz and up to DSD256 11.28MHz.
You can use the multifunction button on the front to navigate through the various menus and settings
available, and to manage the output level for the amplifier.

1: Mains socket
Connect the power cable supplied to this socket.
2: ON/OFF
Use the ON/OFF switch to turn the device on and
off.
3: USB UPDATE
The USB UPDATE port must only be used to
update the product firmware, if necessary.
Refer to the 'Firmware update' section for more
information.
4: USB
The USB port allows you to connect a digital
audio source (computer, etc.) using a USB 2.0
Type B cable.
5: TOSLINK
The TOSLINK socket is an optical connector
that allows you to connect a digital audio source
(Digital Audio Player, etc.) using a digital optical
cable.
The signal can be a stereo PCM signal up to
192kHz.
6: COAX
The COAX socket is a connector that allows you
to connect a digital source using a digital audio
coaxial cable.
The signal can be a stereo PCM signal up to
192kHz.
7: LEFT – RIGHT
The LEFT – RIGHT sockets are connectors that
allow you to connect an analogue source using
analogue coaxial audio cables.
8: RIGHT – LEFT OUTPUT
The XLR sockets are balanced audio connectors
that route the audio signal once it has been
converted to analogue format.
These sockets also allow you to use Arche as a
digital-to-analogue audio converter. The audio
signal of the digital input source (either USB/
TOSLINK/COAX) will be routed to the digital-
to-analogue converter to then be transferred
to analogue audio outputs 8 and 9 in analogue
stereo format.
We recommend using this output to achieve the
best possible performance. The output level is
driven by the rotary potentiometer.
We recommend setting the output level at 99
and then checking the sound level using the
external amplifier.
9: RIGHT – LEFT OUTPUT
The
RCA
sockets
are
unbalanced
connectors that route the audio signal once it has
been converted to analogue format.
These sockets also allow you to use Arche as a
digital-to-analogue audio converter. The audio
signal of the digital input source (either USB/
TOSLINK/COAX) will be routed to the digital-
to-analogue converter to then be transferred
to analogue audio outputs 8 and 9 in analogue
stereo format.
We recommend setting the output level at 99
and then checking the sound level using the
external amplifier.
