8. Installation

8.1 Installation in a rack
The FBQ2496 requires one height unit (1 HE) for mounting in a 19" rack.
Please keep in mind that an additional 10 cm (4") of depth in the back are
required to enable trouble-free access to the connectors on the rear panel.
For rack installation, please use M6 machine screws and nuts.
Please make sure that your FBQ2496 has enough cooling air, and never put it on
an amp or other heat-emitting equipment to avoid overheating.
8.2 Audio connections
The inputs and outputs on your FEEDBACK DESTROYER PRO are laid out
completely balanced. Whenever possible, try to establish balanced connections
to other equipment in order to maximize disturb signal compensation.
MIDI connections (IN/OUT/THRU) are established using the standard DIN
connectors. Data transmission is achieved using a fl oating opto-coupler.

be sufficiently earthed during and after the installation; otherwise,
electrostatic discharges may negatively affect the operating
characteristics of your equipment.
