Congratulations on your purchase of the Radial ProD8. The Radial ProD8 is a simple yet remarkably clever direct box in that it provides all of the standard features one would find in a typical rackmount DI plus several refinements: First off, it jams eight (8) direct boxes into a single rack space making it the highest density DI on the market.
GROUND LIFT As previously mentioned, the ‘engine’ inside the ProD8 is the Radial transformer. This ‘hi-Z to lo-Z’ device is designed to convert the impedance and balance the signal so that it matches the level of a typical micro- phone. This way, the keyboards connected to the ProD8 can be ‘managed’ just like microphones and used with mic splitters as well as the mic inputs on the mixing console.
True to the Music ¼" PHONE PANEL REVERSABLE RACK EARS allow you to setup the ProD8 with either the ¼" jacks or XLR connectors facing front. IN-A/B dual inputs on each channel auto-merge to mono. THRU parallel thru-put connects to on-stage amp or mixer for personal monitoring.
CHASSIS GROUNDING The Radial ProD8 is equipped with a threaded ground lug on the chassis to allow star grounding. The ground lug connection, along with the internal chassis ground switch, would likely only be used in complex stage set-ups where extreme noise problems may occur.
THRU and the balanced XLR output to the PA system. The Radial ProD8 of course does this and then multiplies this by eight. Since the ProD8 is so fl exible, the following diagrams show some of the system set-ups that you could apply.
The LOOP jack on each channel works like an "insert" connection on a mixing console. The LOOP jack is a TRS type that can send the signal out to a processor and return it to the ProD8 signal path. Connect the input and output of an effects processor to the LOOP jack using an "insert cable"...
The use of backing tracks has become common in today’s concerts as fans expect to hear the full orches- tration and backing vocals of their favorite songs. The ProD8 provides an effective means to connect two tape recorders via the dual A/B merged inputs on each channel. Simply place the back-up recorder on mute and sync both machines together.
ProD8 transformer. Also, you will then have to send the ProD8 outputs to the mic-pre inputs on the second mixer as the proD8 outputs are mic level (not line level). This means that you will be using multiple buffers which could add some hiss or system noise.
