Power Amplifier/Speaker connections

DOUBLE CHECK the wiring from the Exaktbox to power amplifier to speaker terminals!
If there are any mis-wires or wrong speaker definintions in the Exaktbox, you may blow the speaker drive units, so take care.

If this is the first connection use the standard Aktiv test scenario.

1. Switch off ALL power amplifiers.
2. Disconnect any power amplifier to speakers connections
3. Set to a low volume value, e.g 40-50
4. Do the following tests 5,6,7,8 starting with the Bass connections, then Midrange, then tweeter and finally super tweeter in that order.
5. Connect respective (Bass or Mid or tweeter ot super-tweeter) power amplifier connection to the Bass connection (Bass or Mid or tweeter ot super-tweeter) of the speaker.
6. Switch on the respective amplifier and play some Music. Check that you are only getting (Bass or Mid or tweeter ot super-tweeter) audio from that speaker drive unit.
7. Stop the Music playing.
8. Leave this cable connected go to Step4 and connect the next speaker drive unit in the list.

If you change speaker or variant, this may also change the Exaktbox terminations so DOUBLE CHECK
