DAK’s Bluetooth Upgrade

Turn Your Old Home Stereo Receiver into a Bluetooth Powerhouse


SKU: 3502.

Don’t be locked out from listening to great quality wireless Bluetooth audio on your vintage stereo equipment.


DAK’s Bluetooth Upgrade is a powerful tool that can both receive Bluetooth signal from any Bluetooth equipped audio source, and it can transmit Bluetooth signal to any Bluetooth ready audio device.


You only need to get one Bluetooth Upgrade if your smartphone, iPod, or computer already has Bluetooth capability.


But if you don’t have an audio source with Bluetooth capability, you aren’t sure, or you just want to get maximum flexibility and pair any two devices together, you’ll need to get two Bluetooth Upgrades and pair them with each other.


Don’t Replace Your Home Stereo: Just Add Bluetooth to it!

If you take good care of your stereo equipment like I do, then your decades old home stereo system still works like a charm. But now that we all have our music stored in digital formats on our tiny smartphones, computers and mp3 players, our home stereo systems don’t get as much use as they used to.

And the funny thing is that your home stereo system sounds as good as it ever did, and is way better quality than computer speakers, or those dreadful, tinny, cheap smartphone speakers. It’s just that your old home stereo receiver can’t compete with the convenience of your digital library.

And that’s where DAK’s Bluetooth Upgrade comes in. It’s the perfect bridge between your hi-fi equipment and digital age convenience.

One Small Upgrade, Full Bluetooth Compatibility

DAK’s Bluetooth Receiver Upgrade turns your current stereo system into a Bluetooth powerhouse in under two minutes. It doesn’t matter how ancient, antique or archaic your stereo receiver is. DAK’s Bluetooth Receiver Upgrade is guaranteed to be fully 100% compatible with your stereo system.

There’s no assembly required. Just plug your Bluetooth Receiver Upgrade into your stereo receiver’s aux or line input, power it on and pair it directly with your smartphone, tablet or PC to create the perfect bridge between your digital music library and your cherished analog stereo equipment.

Plug and Play

DAK’s Bluetooth Receiver Upgrade has a 3.5mm line output, so it’s easy to add Bluetooth capability to anything with a line/aux input or headphone jack. So old PA speakers, headphones and amplifiers can all get Bluetooth capability just by plugging in your Bluetooth Receiver Upgrade to the line input.

Fully Portable with Rechargeable Battery Built in

Never worry about finding extra outlet space, or even being near one, because this Bluetooth Receiver Upgrade has a built in rechargeable battery that’ll last you 8-10 hours on a single charge. So even if you’re using this as a stationary unit for your home stereo receiver, you’ll want to have the extra flexibility to use it on the go whenever you please.

Flawless, CD Quality Wireless Audio

What really sets DAK’s Bluetooth Receiver Upgrade apart from other Bluetooth receivers is that we use aptX low latency profile, so you’ll wirelessly play your music at flawless, CD quality with the complete frequency range every time. Standard Bluetooth profiles compress your audio by cutting out some of the higher frequencies from your music.

It doesn’t matter whether or not you notice the missing frequencies. You don’t want to intentionally cut out chunks of audio from your favorite songs.

Transmits Bluetooth Audio, Too, For Wireless TV

DAK’s Bluetooth Receiver Upgrade doubles as a Bluetooth transmitter, so don’t worry if your music source isn’t already Bluetooth equipped. You won’t just be using it to add Bluetooth to an old PC, iPod or CD player (all music sources) without Bluetooth capability, you’ll use it to watch TV through your favorite pair of headphones. If you’ve got a sleeping spouse, neighbor or kids, you’ll love watching Netflix in bed at full volume, while everybody else gets complete silence. If you have a pair of Bluetooth headphones already, you’ll only need one Bluetooth Receiver Upgrade to transmit the audio from your TV to your headphones. Otherwise, you’ll need a pair of Bluetooth Receiver Upgrades—one to transmit and the other to receive.

Low Latency Solves Audio/Video Syncing Issues

The lag time between the audio and video signal is nominal. Your latency time with DAK’s Bluetooth Receiver Upgrade is only 32 milliseconds long. The maximum recommended delay between audio/video is 40 milliseconds. Compare that with the standard Bluetooth latency of 150 milliseconds—that’s a difference you’ll notice when you’re watching your TV show.

Covered By DAK’s 100% Satisfisfaction Guarantee

I’m so sure that you’ll love the freedom you get from your new Bluetooth Receiver Upgrade, that if you’re not 100% thrilled with the sound quality, the ease of use or the operating range, simply return your unit within 30 days for a full merchandise refund to the credit card you used when you ordered. No restocking fee nonsense. You also get a full year’s warranty against manufacturer defects.

So, what is aptX codec?

Bluetooth signal is designed to transfer information through little wireless packets at high speeds. However, as wireless transmissions go, there is a slight delay or lag time between one wireless terminal to the other. It’s physics, and it’s really not a big deal, unless you’re trying to sync audio with video.

That’s when aptX low latency becomes necessary. aptX low latency reduces your wireless lag time to about 32 milliseconds. Our eyes only notice video/audio sync issues with delays over 40 milliseconds.
