1. INTRODUCTION Whether you are on the stage or in the studio, you often find that you need to connect an audio source to your mixing console, but you dont have the appropriate connectors. For example, only few keyboards feature balanced outputs; guitars should not be connected directly to the console; and placing a microphone in front of an amp is not always an ideal solution, because the mic will pick up unwanted signals from other instruments, too. Low frequency signals (e.g. produced by a b

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 cl

2.3 Converting a microphone signal E Fig. 2.3: Connecting a microphone Sometimes all thats available (especially when all other mics are in use) is an unbalanced high impedance microphone with an unbalanced jack. With the ULTRA-DI PRO long cable runs to the console can be established without fear of picking up noise and hum. Just plug the jack into the input and connect the output to the consoles mic input. 2.4 Tapping a signal from a power amplifier output When no line out is available it is
