not place your ULTRAGRAPHPRO on high-temperature devices such as power
ampliers etc. to avoid overheating.

illustrations show how these cables should be laid out. Please use exclusively
high-grade cabels.

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
