ULTRAGRAPH PRO FBQ6200/FBQ3102/FBQ1502 User Manual

4. Installation

4.1 Rack mounting

The FBQ1502 requires one height unit (1 HU) for mounting in a 19" rack,
the FBQ3102 two height units, and the FBQ6200 three height units. Please allow
at least an additional 4" of space for the connectors on the back panel.
Be sure that there is enough space around the unit for cooling and please do
not place your ULTRAGRAPH PRO on high-temperature devices such as power
amplifiers etc. to avoid overheating.
For rack mounting, please use M6 metal nuts and bolts.

4.2 Audio connections

You will need many different cables for the various applications. The following
illustrations show how these cables should be laid out. Please use exclusively
high-grade cabels.
The ULTRAGRAPH PRO is installed with electronically servo-balanced inputs and
outputs to avoid hum noise problems.
You can, of course, also connect unbalanced devices to the balanced inputs/
outputs. Either use mono plugs, or connect the ring and sleeve of stereo plugs
(bridge pin 1 and pin 3 when using XLR connectors).
◊
Please ensure that only qualified personnel install and operate the
ULTRAGRAPH PRO. During installation and operation the user must
have sufficient electrical contact to earth. Electrostatic charges might
affect the operation of the unit.
