A brief resume of Drive-in

How do drive in movies get sound?

How do you get sound at a drive in movie?

How does sound work at a drive in movie?

In the past the drive-in operator gives you a portable radio tuned at the frequency of the program.

Modern Cars has high fidelity audio in Car sound system and the new films use many sound effects.

For this reason on modern Drive-in to use the own car radio is preferable.

When you come in to the show you must tune your radio at the frequency used by the Drive-in to get the audio of the movie. The right frequency is shown on the advertisement on the screen an on several signs.

What radio station is drive in?

The one choose for the operator of the Drive-in. It change depending on the free frequency available on the area.

How do drive-in movies distribute the sound on the cars?

Like a normal FM radio broadcast the sound to their listener: with an FM Transmitter

How FM transmitter works for drive-in?

Using the Car Radio to tune the selected frequency of the Drive-in operator to hear the function.

What are the equipment needed for a Drive-in spectacle?

  • Screen
  • Video projector
  • DVD player or Computer with an output to the Video Projector
  • FM Radio Transmitter
  • Antenna
  • Cables to interconnect all the equipment

How it works?

  • The Player send the image to the Video projector
  • The Player send the Audio to the FM Transmitter
  • The operator select a frequency free on the area they are located
  • The operator set the selected frequency on the FM Transmitter.
  • The Audience tune on the car radio the frequency selected.
  • The audio of the movie or the religious ceremonies is heard on the Car Radio

What are the applications?

Entertainment, Live Concerts, movies, theatre, religious ceremonies, Church and emergency departments.

Why to use an FM Broadcast Transmitter?

  • All the cars has a Car Radio
  • Often the sound of the modern cars are Hi Fidelity powerful audio with optimum quality.
  • The transmission of FM is the most reliable and cheep technology known nowadays.
  • The quantity of users is unlimited.
  • The covered area depends exclusively on the power set on the FM Transmitter. Typically, from 200 meters up to 15 km.
  • Receiving the sound on the own radio guarantees social distance from other spectators
  • Using the own car radio is safe, spectators don’t touch nothing outside the car and no equipment is needed to provide them (in the old Drive-in was usual they give you a small radio with loudspeaker to hear the function.

a walk around the problem of social distance to protect yourself from Covid

Sometimes they come back! After Coronavirus, the prospect is that nothing will be like before, an impression that is filling our days, something that indicates a sort of change in change, concepts that want to think of something new but to indicate the return of others. The health emergency that hit the world forces us to keep the social distance to safeguard our health, unfortunately modernity has integrated everything except social isolation, so there is a need to somehow reinvent the leisure activities that characterized our free time, including watching a movie with friends in the cinema.
This activity has been discontinued and postponed to future and uncertain times. But there is something that exactly replaces the pleasant experience of watching a cinematographic or theatrical show respecting the sanitary rules,the drive-in that made so much dream past generations!
