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. Please make sure that the voltage indicated on the unit matches your local voltage, before you attempt to connect and operate the VINTAGER AC112. Blown fuses may only be replaced by fuses of the same type and rating. Some models allow for inserting the fuse holder in two different positions, in order to switch over from 230 V to 115 V operation, and vice versa. Please note that for 115 V operation outside Europe, you need to use a fuse of a higher rating (see chapter 3 INSTALLATION). Use the enclosed power cord to connect the unit to the mains. Please take the time to complete and return the warranty card within 14 days of the date of purchase, otherwise you will lose the right to the extended warranty.

INTRODUCTION ULTRA-DI PRO DI4000 2. APPLICATIONS 2. 1 Tapping signal from a (bass)guitar Fig. 2. 1: Guitar ß DI box ß Guitar Amp/Mixer This figure shows the standard application of any Direct Inject box. The signal to the amplifier is unaffected, it is just tapped off to be routed to the microphone input of the mixer. Especially bass guitars benefit from this application. It is difficult to find a microphone which handles high level low frequencies well and with a linear frequency response. Using the ULTRA-DI PRO will give you clean and crisp sound. Connect the ULTRA-DI PRO after any effects devices, so that their effect will be heard over the PA system or on the recording. 2. 2 Converting the output of a keyboard / DJ-mixer / headphone plug Fig. 2. 2: DJ-mixer ß 2 x DI box ß Mixer This configuration can be used with a keyboard, DJ-mixer, headphone output, drum kit or any (stereo or mono) line source. In all cases where you want to run long lines, for instance to the FOH (Front Of House) desk. The signal can be linked through to another amplifier, if the keyboard player/ DJ/etc. [. . . ] This also applies to defects caused by normal wear and tear, in particular, of faders, potentiometers, keys/buttons and similar parts.
