 Breathe New Life Into Old Audio Gear With Bluetooth

With the growing popularity of the wireless streaming, either from the internet or directly from portable sources, those that own older home theater gear that still works fine are getting left behind. After all, you already have a great audio setup, but just lack some newer content access capability.

Although you can't magically morph that old gear into the latest and greatest, there are some add-on upgrades that you can make that will provide more flexibility on how you can access more content.

One easy option is to add Bluetooth capability to and old stereo or home theater receiver, and even that old CD player or Audio Cassette Tape Deck.

One group of products that is available to accomplish this is iClever's trio of Bluetooth adapters, the IC-BTT01 Universal Bluetooth Transmitter, IC-BTR03 Bluetooth Audio Receiver, and the IC-BTT02 convertible Bluetooth Transmitter/Receiver.

All three units are a little smaller than a credit card (but thicker) and incorporate a built-in rechargeable battery that takes about 2-3 hours to charge via USB connection (cable included). Once charged, each unit can deliver about 10-11 hours of use time. The maximum effective Bluetooth transmission range is about 30 feet.

Depending what you need to do, will determine which of the three units might work best.

IC-BTT01 Universal Bluetooth Transmitter

If you have a CD player, tape deck, or other audio source device that you would like to free from the hassle of a physical connection cable with a stereo, home theater receiver, powered speaker, or headphones that already has built-in Bluetooth reception capability, then the IC-BTT01 transmitter might be just the solution.

If your audio source device (CD player or Tape Deck) has RCA audio outputs, you will need to get an RCA-to-3.5mm cable/adapter (Buy from Amazon)  to connect to the audio input on the transmitter. However, once connected, you just pair the transmitter with your compatible Bluetooth-enabled Stereo, home theater receiver, sound bar, powered speaker, or headphones, and you are set to go.

Note: The IC-BTT01 Bluetooth Transmitter cannot be paired with smartphones.

IC-BTR03 Bluetooth Audio Receiver

Now, if you have a Bluetooth source device, such as a smartphone, tablet, or laptop/Desktop PC, and you would like to send music wirelessly to a non-Bluetooth enabled stereo, home theater receiver, sound bar, or powered speaker, then the IC-BTR03 Bluetooth Audio Receiver might be the right solution.

The IC-BTR03 Bluetooth Audio Receiver has a 3.5mm stereo output, but you can either use that option if your stereo, etc... has a 3.5mm stereo input connection option, or simply use a 3.5mm to RCA adapter/cable (3.5mm female to RCA male - Buy From Amazon) to make the physical connection to a stereo/home theater receiver/soundbar.

Once you have it connected, select an associated input on your stereo, pair the iClever Bluetooth Audio receiver with your Bluetooth-enabled source device, and you are set to go.

IC-BTT02 Convertible Bluetooth Transmitter/Receiver

Now, if none of your sources or receiver gear has Bluetooth capability, you can either option for buying both the iClever IC-BTT01 transmitter and IC-BTR03 receiver, or better yet, get two IC-BTT02's, each of which can be configured as a transmitter or receiver.

In other words, using a slide switch on the IC-BTT02, a Transmitter (TX) Mode be engaged that enables any analog device to become a Bluetooth-capable music streaming source, while the Receiver (RX) Mode can enable your stereo, home theater receiver, sound bar, etc.... to receive Bluetooth audio transmissions.

If using the IC-BTT02 with components that only have RCA audio connections, you will need a 3.5mm (male) to RCA (male) cable/adapter (Buy from amazon).

Having spent some time with the BTT01, BTT02, and BTRO3, here is what I encountered.


You can stream music from a Smartphone (or another Bluetooth-enabled source device) to the BTT-02 (receiver mode) or BTR03.

This means you can add Bluetooth reception capability to any stereo, home theater receiver, TV, or sound bar that has analog audio inputs (as mention above, you may need a 3.5mm/RCA adapter).

Also, you can wirelessly transmit both music and movie audio from a TV or Blu-ray/DVD/CD player that has analog audio outputs, using the BRR01 or BTT02 (transmitter mode) to an already Bluetooth-enabled speaker, sound bar, or home theater receiver.

However, another benefit of the BTT01, BTT02, and BTRO3 is that they can pair with other. This means that you can add Bluetooth capability to both a non-already Bluetooth-enabled source device and Stereo/Home Theater Receiver, or sound bar.

One thing to point out, though, is the sound quality is just fair. CDs, DVDs, and Blu-ray Discs don't sound as good as when the player is physically connected to a stereo or home theater receiver, as the conversion from analog audio to Bluetooth results in loss of higher frequencies and audio depth. However, it is convenient if your components are some distance away from each other. On the other hand, there is a lip sync issue with movie audio content - which is not good for TV or movie viewing. If you encounter this issue, here are some solutions that may work - However, the overall sound quality, just as with music, is still only fair.

What I Liked

  • Very compact size
  • Easy to set up and use - provided you have the correct cable adapters for your components.
  • Adds more audio connection and content access flexibility to older stereo and home theater components.

    What I Didn't Like

    • No 3.5mm/RCA Adapter Cables included.
    • Sound Quality is not as good as when using physical connections, which is typical of Bluetooth.
    • Lip-sync issues when transmitters are used with DVD/Blu-ray, or other source devices that contain both audio/video connections (TV shows/Movies).
    • Units need periodically charging - (no option for AC Adapter plug-in option)

    Final Take

    For adding Bluetooth capability to a non-Bluetooth-enabled stereo/home theater receiver, or powered speaker so you can play easily playback music wirelessly from a Bluetooth-enabled smartphone or other compatible portable device, the iClever products are easy to use and sound good for that purpose.

    However, for use with analog audio sources for music or home theater listening, you do sacrifice sound quality over what you would experience with a direct physical connection - and, of course, for home theater use, you will not be able to transfer surround sound signals wirelessly using Bluetooth.
