Speaker-signal currents are potentially hazardous to the human body.
When the system is in use, make sure that the connectors are secured against inadvertent touch.

Wiring

Before connecting your K&F SPECTRA 212 speaker, switch off all devices and turn down all faders
and encoders.
Be sure to use high-end speaker cables with an appropriate wire gauge. Select the wire gauge with
regard to the cable length.
Min. Wire Gauge (mm²) = Req. Cable Length (m) / (2xSpeaker Impedance (Ohm))
To connect the mixing console to the power-amp inputs, use shielded 2-pole balanced microphone
cables equipped with quality connectors.
Avoid creating ground loops.
Be sure to follow the pinouts shown in this manual.
Check for correct polarity of the speaker links to the power amplifier.
Upon completing wiring, ensure that the connected speaker channels are working in phase, for
example, using a phase 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 can-
not be located properly.
When connecting multiple speakers, you can daisy-chain the signal from one speaker to the next.
Make sure that the total impedance of all speakers connected to an amplifier does not fall below
the minimum impedance specified for the amplifier. 1/R1 + 1/R2 + 1/R3 + ... = 1/Rtotal
