Switching Between Passive And Bi-Amp Mode - Yamaha CZR15 Owner's Manual

Switching Between Passive and Bi-amp Mode

The factory setting for CZR internal wiring is the Passive mode. However, you can change the setting to the Bi-amp
mode. When driving in the Bi-amp mode, you must use an external crossover processor and the output from a 2-
channel amplifier. By driving in the Bi-amp mode, protection can be set separately for the LF and HF, and precise set-
tings can be made for crossover frequency and time alignment between the LF and HF. This optimizes the perfor-
mance capacity of each unit and increases the limit capability.
1.
Using a M5 Phillips head screwdriver, remove all fixing screws on the rear panel, and remove the rear panel.
NOTE
• When removing the screws, make sure not to push the screws strongly. This may cause the nuts inside the cabinet to fall off.
• If the rear panel cannot smoothly be removed, hook the notches using a flat-bladed screwdriver, and pull out.
Screws (six total)
2.
Disconnect the input and output cable connectors from the [PASSIVE IN]/[PASSIVE OUT] connectors on the network base,
and connect them to [BI-AMP IN]/[BI-AMP OUT] connectors respectively.
