User Guide

All Cuboid loudspeakers are tted with two standard NL4 type connectors.
These have two pairs of terminals.
Cuboid uses only pins 1+ and 1-. These are linked across the two connectors,
providing a useful link to a second loudspeaker of the same model. No more than
two Cuboids should be connected to a single amplier channel.
2+ and 2- are not connected and are not linked through.
For connection, we recommend using a exible cable with a minimum cross-
sectional area of 1.5mm²
