True to the Music OVERVIEW The Radial ProD8 is an 8 channel passive direct box and does not require any powering whatsoever to make it work. The high performance Radial transformers are extremely efficient and will both balance the signal and convert the high source impedance of your keyboards to a balanced, mic level low impedance output. All channels are identical and completely isolated. Each channel features two inputs that are merged to mono using a resistive mixer.
True to the Music ¼" PHONE PANEL 1 REVERSABLE RACK EARS allow you to setup the ProD8 with either the ¼" jacks or XLR connectors facing front. 2 IN-A/B dual inputs on each channel auto-merge to mono. 3 THRU parallel thru-put connects to on-stage amp or mixer for personal monitoring. 4 LOOP each channel features an effects-loop on a TRS jack. Works like an insert on a mixing console. 5 -15dB PAD reduces the input level by -15dB to prevent overload from high output devices.
True to the Music RACKMOUNT OPTIONS Reversible rack rails allow you to decide which connector panel faces the front of your rack. Depending on your system setup, you may want to have the XLRs facing ‘out’ of your rack and the ¼” inputs and thru-puts on the inside. This would be the most common approach especially if you are using a number of rack-mounted sound modules. Some system techs prefer to have access to the ¼" inputs.
True to the Music USING THE RADIAL ProD8 For live touring, the most common approach to using a direct box is to connect the instrument to the A/B inputs, your personal monitoring amp system from the 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 flexible, the following diagrams show some of the system set-ups that you could apply.
True to the Music ADDING EFFECTS 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" which may be purchased at a music retailer. Each channel is fitted with an internal EFX PRE/POST switch.

For instance, in the example below channels 1 and 2 are used for a stereo master keyboard and a pre-patched backup that is ready to go. Channels 3 through 6 are used for mono sound modules.

Today, keyboard players often travel with back-ups to minimize downtime should a module fail. The merged inputs allow a second set of modules or keyboards to be connected in standby should a back-up be needed.
True to the Music REDUNDANT BACK-UP TRACKS The use of backing tracks has become common in today’s concerts as fans expect to hear the full orchestration 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. Should a problem occur, mute the main playback recorder and un-mute the backup system.
True to the Music FAQ Can I use the ProD8 with guitars or basses? Yes of course you can, but keep in mind that the resistive mixer may apply a bit of a load on the instrument. This will not be noticeable with active (battery equipped) instruments like acoustic guitars, but you may notice a slight drop in level with low output instruments with passive pickups. Can I use high output +4dB balanced sources with the ProD8? Not really.
