Wireless headphones allow the passengers to enjoy video
soundtracks without distracting or disturbing the driver.
Headphones are available in both infrared and radio frequency
versions, in adult and child sizes and in single or dual
source models. With built-in features like source switching,
self-contained volume control and no wires to get tangled
up, wireless headphones are the standard source of rear
seat audio in most video systems.
It’s also beneficial to have the full
factory audio system available to video soundtracks or
MP3 music discs. EARMARK can inject the theater sound
into your existing stereo system no matter what you drive.
The most common method is with a radio frequency modulator
which multiplexes the theater sound in on FM preset-one.
This is synonymous with bringing a VCR, satellite TV receiver
or video game into your home TV via channel 3. But the
best audio quality is achieved by using an auxiliary or
changer input on the existing stereo. And EARMARK carries
a wide variety of interface adapters for this function.
Many of today’s aftermarket CD players have dedicated
auxiliary inputs for theater sound. Several multimedia
source units are equipped with dual zone audio. These
multimedia source units act as a full audio selector providing
separate options for front and rear seat passengers. A
dual zone receiver will provide either fixed or variable
line outputs to the rear zone. Fixed level outputs work
perfectly with wireless headphones or localized controls.
This way changing the front seat volume has zero effect
on the rear seat audio. Rear zone variable outputs are
selected when the volume control is intended to remain
on the source unit.
For those who want to capture the full
audio effect of Dolby encoded soundtracks, 5.1 processors
are available. These processors also provide numerous
sound-field adjustments to perfectly tune your system
to your vehicle environment.
For the most advanced audio/video system
available, there’s Alpine F1 Status. Alpine has
selected EARMARK as the exclusive F1 Status representative
for North Texas. You can audition this amazing system
in the award-winning TechnoVan
found at the EARMARK Addison Store.
