Wiring Instructions
•
Before connecting your SONA 8 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.
•
Avoid creating ground loops.
•
Be sure to note the pinouts shown in these operating instructions.
•
Make sure that the +/- polarity of the speakers at the amplifier is correct. When
simultaneously using power amplifiers from different manufacturers, be sure to use the
correct specific pin configuration. It may be necessary to modify the pin configuration
on the power amplifiers or on the connectors leading to them.
•
Upon completing wiring, ensure that the connected speaker channels are working
in phase, for example, using a voltage tester. When the connected channels are used
simultaneously, you can identify out-of-phase statuses by bass cancellation or mid-
frequency signals (e.g. voices) that cannot be located properly.
•
If several loudspeakers are connected, the signal can be linked through parallel
from one loudspeaker to the next. Please make sure that the total impedance of the
loudspeakers R(Ohm) is not lower than the minimal impedance indicated on the power
amplifier.
1/R1 + 1/R2 + 1/R3 + ... = 1/Rtotal
