Training Information Point
When you remove the electrical wires from the speaker transformer terminals, make sure to record the terminal connections. When you replace the speakers, put the
electrical wires to the same terminals.
When you remove the speaker from the PSU assembly, make sure you do not damage the speaker gasket (прокладка). This gasket is between the speaker and the PSU assembly. Purpose
The PA system lavatory speakers supply audio to the lavatories.
Features
Each lavatory PSU has a 5-inch speaker. A latch holds the PSU assembly closed. To open the assembly, put a small rod in the access hole. Hold the PSU panel, and
push the rod against the spring clip to release the latch. Lower the PSU panel assembly until the lanyard holds the PSU.
Each speaker has a transformer. The transformer matches the speaker impedance to the line impedance. Two electrical wires connect the speaker transformer terminals to the PA amplifier.
Install and remove the speaker and transformer as one assembly. 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | Поиск по сайту:
