Example 2 – The aircraft has four passenger seats. Each seat has a headphone jack with a select
switch. These jacks also have LEDs for lighting. The LEDs require +5v DC. The +5v DC will be
supplied by the Headphone Amp. There are three audio sources in the system. Each passenger
(seat) can listen to all sources.
Configure the switches on the Headphone Distribution Amplifier, as shown above. Leave all other
unused switches in the OFF position.
