8. Wiring Instructions
• Before connecting your GRAVIS 15 loudspeaker switch off all equipment and turn down
all level controls.
• Only use high-quality speaker cables with a sufficient wire gauge. The wire gauge
depends on the length of the speaker cable.
Minimum Wire Gauge (mm²)
= Required Cable Length (m) / (2 x Speaker Impedance (Ohm))
• For connections to the power amplifier inputs, please use 2-pin shielded microphone
cable (balanced) with high-quality connectors.
