SAFETY PRECAUTIONS

Note

Read this user manual completely.
Here you will find all information you need for operating the device.

Note

Any tampering with or modifications on the unit will void the warranty. Use the device only in
accordance with the user manual.
Use only accessories specified by the manufacturer.

Mains Connection

The device can be operated on a mains voltage of 100 – 240 VAC / 50-60 Hz. The mains connection is
made with an external wall plug transformer (switching power supply) which delivers the operating
voltage for the StudioCube. Primary mains adaptors, which are optionally available, ensure a
worldwide use of the device.

• Use no faulty adaptors or connection lines!

• Disconnect the power supply from mains before opening the unit!

Moisture

To avoid any hazard through fire or an electric shock, this unit must not be exposed to rain or
moisture. Spraying water or dripping liquids must not get into the unit, either. Do not place any
objects containing liquids such as beverages or vases on the device.

When the device is taken from a cold to a warm place, water condensation may occur inside.
Only connect to mains after the device has warmed up to room temperature.

Mounting

The surface of the device may become hot during operation. Make sure to provide for a sufficient air
circulation. Avoid direct sunlight and close proximity to radiators, radiant heaters and similar heat
sources.
When mounting the unit into a rack, make sure to provide for a sufficient air flow and do not mount
it directly above/under a power amplifier.

Danger through high Listening Levels

With headphones unhealthy volume levels can be achieved.
So before putting on your headphones, always check that the selected volume level is not too high.

For detailed information see page 12.

INSTALLATION

UNPACKING

After unpacking the StudioCube please check the device for potential transport damage. In case of
visible damage you must under no circumstances connect the device to mains. Please contact your
dealer immediately then.

Scope of Delivery:

• StudioCube device

• Wall plug power supply with connection lead

• Country-specific AC primary adaptor

• Configuration jumper

• User manual

• Guarantee card

Note

We recommend you keep the whole packaging material for a dispatch at a subsequent date. Thus
you will avoid transport damage.

By no means use “styrofoam chips“ or similar packaging material.
During transport the device will “joggle“ its way down to the bottom of the box and damage may
occur!
If the original packaging is missing, it’s best to use bubble foil in which to wrap the device generously.
Then pack the whole issue in a solid cardBoard box.

SETUP

Always put the StudioCube on a solid base. Alternatively you can mount the unit on a stand or under
a table by using the optional yoke.
Its compact size and low weight make the StudioCube also very easy to transport.

Note

• Do not expose the device to rain or moisture!

• Do not expose the device to extreme temperatures!

• Do not place the device near strong electric or magnetic fields!

• Avoid using too short connection cables.

CONNECTION

First connect the StudioCube via its mains connector (POWER) with the wall plug power supply, then
connect the power supply to mains.
The external wide-range switching power supply of the StudioCube will adapt automatically to
different mains voltages around the world. A travel set with primary adaptors for other countries and
mains outlets is optionally available.
