5. INSTALLATION
5.1 Rack mounting
The BEHRINGER TUBECOMPOSER fits into one standard 19" rack unit of space (3 1/2" / 89.5 mm). Please
allow at least an additional 4" depth for the connectors on the back panel. Be sure that there is enough air
space around the unit for cooling and please do not place the TUBECOMPOSER on high temperature devices
such as power amplifiers etc. to avoid overheating.
5.2 Mains connection
The mains connection of the TUBECOMPOSER is made by using a mains cable and a standard IEC
receptacle. It meets all of the international safety certification requirements.
+ Please make sure that all units have a proper ground connection. For your own safety, it is
advisable not to remove the ground connection within the units or at the supply, or fail to
make this connection at all.
Before you switch on the unit, check that it is configured to match your AC mains voltage requirements. If it
does not comply, then it is necessary to switch the operating voltage to the correct supply requirements
BEFORE turning on the unit, otherwise the unit could be severely damaged. You will find this combined fuse
holder/voltage selector at the back, adjacent to the IEC receptacle. IMPORTANT: This does not apply for
general export models which are built for one operating voltage only.
The AC voltage selection is defined by the position of the fuse holder. If you intend to change the operating
voltage, remove the fuse holder and twist it by 180 degrees before you reinsert it. Matching the two markers
monitors the selected voltage.
+ If the unit is switched to another operating voltage, the fuse rating must be changed. See the
technical specifications in the appendix.
A safety fuse protects the unit from serious defects. If the fuse blows, this is a warning sign and always
indicates that the circuit is overloaded. The fault must always be repaired before the fuse is replaced. If the
safety fuse is faulty and needs replacing after the unit is repaired, please make sure that you replace it only
with the identical type and rating. NEVER use fuses of different ratings or cover faulty fuses with aluminium foil.
This can cause fire and electric shocks and will endanger your life and the lives of others.
5.3 Audio connections
As standard, the BEHRINGER TUBECOMPOSER is installed with electronically servo-balanced inputs and
outputs. This circuit design features automatic hum and noise reduction for balanced signals and thus allows
