Reconfiguring the KAV-250afor Bridged Operation

Toolsneeded:T-15Torx wrenchandoneribbon connectioncable

1.Turnthe KAV-250aoff by pressingthe powerbutton(1) on the front panel. Theblue powerLED(2) extinguishes.Unplugthe ACpowercord from the IECpower connector(13) on the backpanel.

2.Usingthe T-15Torxwrench,removethe 12 screwsthat securethe amplifier cover. Carefullyremovethe cover.

3.Locatethe small PCboardat the rear of eachamplifier channelandjumperpins labeledJ4, J5, andJ6.

4.Connectoneendof the ribbonconnectioncableto jumperpin J4 onthe left
