Car cassette adapters are one of the unsung heroes of the digital age. They provided hands-free in-car cell phone calling, CD, and MP3 in-car capabilities long before they became standard features of in-car stereos!
For teenagers of the 1990s, they were, quite simply, the best thing since sliced bread!
Here we take a quick look at these venerable pieces of kit, and ask you to join us as we bow before the altar of the cassette tape adapter!
What are car cassette adapters?
Car cassette adapters work, on a basic level, by allowing you to play external audio devices through your car's speakers, if you have older cassette-only in-car entertainment systems. They came to prominence in the age of the CD and were the go-to car entertainment accessory for many years.
For this reason, they are widely considered as one of the biggest unsung heroes of the digital age. We are being a little hyperbolic, but for anyone old enough to have ever used them, they truly were a lifesaver.
You can still buy them today, but with car stereos usually including CD, USB ports, Bluetooth capability or auxiliary ports, they have become largely redundant.
The technology was first patented in 1988 and was initially intended for use with portable audio players and car cassette decks. They were initially envisaged for use with portable CD players, but they also happened to be great for later portable audio devices like MP3 players, minidisc players, etc.
But they also had some very interesting additional uses. Many providing some of the features of modern in-car systems that wouldn't become standard for decades.
These included, but were not limited to:
- Hands-free in-car cell phone calling - Yes it really worked!
- Home tape-deck audio adapters - Though very hit and miss.
- Laptop computer or PC audio jack adaptor to cassette deck sound systems - If your built-in or external speakers were trash!
- Handhold game console audio adapters to cassette decks - For a more immersive gaming experience!
They literally were one of the earliest means of connecting many different electronic devices in an age before Bluetooth, wireless, and the IoT.
All hail the cassette adapter!
How does a car cassette adapter work?
Your typical car cassette adapter works through the use of a single-sided writing tape head. This is similar to the recording head on a traditional tape deck.
Connected to this is, usually, a stereo mini-jack with a cord. This cord is then, in turn, connected to the external audio device's output (or headphones) port.
Electrical signals are converted into a magnetic signal by the head as a track plays through the connected audio device. This magnetic signal is then received by the car's tape deck reading head.
Unlike traditional cassette tapes, cassette adaptors lacked a magnetic reel. Magnetic signals were, instead, transmitted directly by a transmitting head positioned where the exposed magnetic tape would normally be.
The cassette deck's reading head, in turn, converts the magnetic signal into an electrical one (as it would with regular cassette tape) which is then amplified by the sound system.
Simple and effective!
Because of the way they work, most car cassette adapters are "one-way" only. This refers to the fact that traditional cassette tapes used a magnetic reel that could be reversed once the tape had finished.
That being said, there are some models on the market that do have double-sided heads that can work in either direction.
These adapters also had a mechanism to simulate tape movement as cassette decks tend to monitor tape movement to ascertain when the tape has finished. This is provided by a rolling wheel that constantly turns and never ends "fooling" the cassette player into not triggering any auto-reverse function it may have.
Car cassette adapters are not to be confused with MP3 players shaped like a traditional cassette tape. These are actually stand-alone MP3 players that can work as they are with headphones or be inserted into a traditional in-car cassette deck.
In the latter case, these players tend to need an external remote control to be operated, but not always. These devices also have a double-sided head too.
Car cassette adapters were later challenged by newer audio adapters like FM transmitters. These interesting devices often required external power to convert the device's electrical signal into radio waves to transmit audio tracks over unused FM frequencies.
The transmitter's signals could then be tuned into using the car's radio. But most user's attested to the superiority in convenience and quality of the car cassette adapter over FM transmitters.
When did they stop putting cassette players in cars?
Cassette players were once the king of in-car sound systems. They were the standard for many decades.
But with the rise of CD, MP3, and other digital audio technologies, their days were ultimately numbered. But they had a surprisingly long market lifespan.
In the United States, the last cars to have cassette players as standard were as late as 2010. After this point, no manufacturers selling cars in the United States offered a tape player either as standard or as an option.
According to a report in the Times at the time, cassette players weren't the only in-car audio tech facing extinction.
"The iPod and its ilk are easing the journey along the path to the increasingly popular concept of file storage known as the cloud -- that place in the Internet ether from which music is streamed, generally through a Web-connected mobile device that communicates with the car by a wireless Bluetooth connection".
But if you miss your old cassette player, you could just connect it to your new-fangled in-car stereo using a trusty audio mini-jack into the auxiliary port.
Nothing says cooler than retro!
Are cassette players still available?
If you have ever wondered if you can still buy cassette players, we have some good news for you. While you may have a hard time finding one in your local electronics store, they appear to be making a comeback.
Much like the growing vinyl scene, cassette tapes appear to be rising in popularity as a cultish popular music format.
"Indie record shops started stocking used cassettes again in recent years. Urban Outfitters started selling new ones. Indie labels and DIY bands started manufacturing new albums on tape.
Some major acts — including Metallica, Wu-Tang Clan, and AC/DC — are even reissuing classic albums as limited-edition cassettes just for Record Store Day, an annual event returning Saturday to indie music shops around the country, including such Minneapolis staples as the Electric Fetus, Hymie’s and Fifth Element." - Star Tribune.
But if you want to make your own mixtapes, you may have a hard time finding blank cassette tapes. While they are still technically in production, you may not find them in your local stockists. However, you should have no difficulties finding them online.
Players, especially portable ones, are also becoming increasingly rare to find in electronics stores. If you want to get your hands on a cassette player, you can find plenty of second-hand units laying around.
Visit vintage electronics stores, car boot sales and auction sites like eBay. You can also grab yourself newer ones off e-commerce sites like Amazon and the like.
Or, if you are really cool, you could just dig out your old cassette player and fire it up!
