Example 3 – The aircraft has eight passenger seats. Seats 1-4 have headphone jacks with no
select switch. These seats have access to XM Radio audio only, which is assigned to Channel B.
Seats 5-8 have headphone jacks with select switches. These jacks also have LEDs for lighting. The
LEDs require +5v DC, which will be supplied by the Headphone Amplifier (SW5 on the small bank of
switches). Seats 5-8 can listen to either audio source: XM Radio or DVD Player.
Configure the switches on the Headphone Distribution Amplifier, as shown above. Leave all other
unused switches in the OFF position.
