Amplifier output connections – iK42
2-
Additionally, the channel 2 output is duplicated on the Speakon™ connector for amplifier channel 1 for Bi-Amp wiring. Similarly,
the channel 4 output is duplicated on the Speakon™ connector for amplifier channel 3. This can be useful for making a connection
to two loudspeakers with one 4-core cable (i.e. Bi-Amp).
On the iK81 model, all outputs are Bi-Amp; each Speakon™ connector carries two amplifier outputs – Channels 1&2, Channels
3&4, Channels 5&6 and Channels 7&8.
Amplifier output connections – iK81 and Bi Amp
In addition, the channel 1 or channel 3 connector (all the Speakon™ connectors on the iK81 model) can also be used if the pair
of amplifier channels is being operated in bridged mode.
Amplifier output connections – Bridge
More than one speaker can be connected to each channel provided the total impedance per channel is not less than 2 ohms. In
bridged mode the minimum total impedance should not be less than 4 ohms.
