LINK. This is the unbalanced parallel output of the ULTRA-DI PRO. Connect this to the input of the backline or monitor amplifier.

INPUT. Connect the source to this 1/4" jack to input the signal.

And The -20 dB ATTENUATION switches greatly increase the operating range of the ULTRA-DI PRO. From the low level signals of a high impedance guitar to the hot speaker terminals of a P.A. amplifier. Depressing both will give 40 dB attenuation.

+Only use the -20 dB switches if you are sure the ULTRA-DI PRO is clipping (overloading) and not your mic pre-amp. Always use as little attenuation as possible to get the best possible signal-to-noise ratio.

Before you connect the unit you should check that the voltage indicator on the voltage selector matches your local line voltage. When you need to replace the fuse, please insert a fuse of the same type and rating.The ULTRA-DI PRO is connected to the mains via an IEC power connector. A suitable power cord is enclosed. Please also note the instructions given in chapter 3 “INSTALLATION”.

Please take the time and ask your dealer to fill in the warranty card. Then return it within 14 days after the date of purchase. Otherwise, you will lose your extended warranty rights. Please check that the SERIAL NUMBER on the unit is the same as the one indicated in the warranty card.

To provide maximum flexibility the ULTRA-DI PRO is also fitted with an unbalanced XLR INPUT to connect the source.
