IMPORTANT:
Shut off power to the Digital
8•Bus’s remote CPU before installing or remov-
ing cards. Also, install your FX cards in order.
For example, put your first FX card in the slot
marked “A,” your second FX card in slot “B,” etc.
1. Loosen the four spring-loaded screws
on the blank cover plate to the FX card slot
you want to fill. See Figure F-3
2. With your finger in the hole on the FX
card (and the components on the circuit
board facing to the left), push the card firmly
into the white connector slots so it fits
snugly. See Figure F-4. Do not touch any of the
circuit board components or solder joints.
3. Replace the cover plate and hand-tighten
the screws. Do not use a screwdriver, as
overtightening the screws may strip the
threads on the D8B.

Installation Instructions for FX Cards
MFX
This card provides
two additional DSP
engines for running
internal effects. The
Digital 8•Bus is
shipped with one MFX
card installed in Slot A.
You can install up to
three more MFX cards
in Slots B, C, and D.
Make sure to install
them in that order. In
other words, if you
install a second card, it
must go into slot B, and
not into slot C or D.
