Keyboard Setup

Connections

Keyboards are connected to the mixer via what are called "direct input" boxes. TSC has two models of these - ProCo CB-1 and Rapco db 100. They should be functionally identical. Here is what the Rapco box looks like:

The first photo is the top view. On one end of the box are three 1/4" jacks: input, pass-through output and ground lift. On the opposite end of the box is an XLR male jack.

Make the following connections:

• Connect a 1/4" to 1/4" balanced (TRS) cable from the keyboard to the input jack (the one marked "Inst High Z In") on the DI box.
• Connect an XLR cable from the XLR jack (the one marked "Low Z Output") on the DI box to the mixer.

Optionally, if the musician playing the keyboard requests it, connect a 1/4" to 1/4" balanced (TRS) cable from the 1/4" pass-through jack (the one marked "Inst High Z Out") on the DI box to the piano monitor (the one closest to the keyboards).

Multiple Keyboards

If there are two keyboards and one plays melody while the other plays effects (similar to the "organ"), the keyboard playing melody should be connected to mixer input _Keyboard 1_ while the keyboard playing effects should be connected to mixer input _Keyboard 2_.
