How To Build Your Own DIY Bluetooth Speaker

You may choose to connect your speakers to Bluetooth for a variety of reasons. By using the Bluetooth capability, you may listen to your favorite tracks on the go. This means you can use your speaker to watch videos on your laptop or as a DJ with your phone.

Purchase a Bluetooth Receiver, esinkin W29-us Bluetooth audio Streaming Sound System Adapter. This wireless audio adaptor enables the connection of devices such as smartphones and tablets to speakers.

To make your speakers Bluetooth-enabled, you’ll need a Bluetooth receiver. The receiver detects and converts a Bluetooth audio signal to an electrical audio stream.

Line level signals are noise-resistant, low-voltage signals. The same signal is output by a preamp, a laptop, and a cell phone.

Unless you’re using headphones, a line-level signal is insufficient to power a speaker. Line level signals require very little energy to deliver a sound signal. Before it reaches your speakers, a line-level signal needs be boosted.

Bluetooth receivers are frequently inexpensive. Generally, a high-quality Bluetooth receiver costs between $10 and $30. A Bluetooth receiver is often equipped with a female aux jack and a female RCA connector.

Additionally, you can purchase Bluetooth receivers that just include a male aux input, which are often used in vehicle audio systems.

Connect the Bluetooth receiver to the Speaker or Speaker System through the included USB cable.

To connect your speakers to your Bluetooth receiver, you’ll need to purchase (or fabricate) a custom cable.

At times, these cables will be easy to locate. However, in certain situations, you may need to improvise.

For connecting to a stereo system, the majority of Bluetooth receivers provide stereo aux and RCA outputs. If, on the other hand, you purchase a car adaptor, it will include a male stereo aux output.

RCA outputs are intended for use with computer speakers, whereas auxiliary outputs are intended for use with stereo speakers in a home context.

Connecting a Bluetooth receiver to an active or powered speaker

To connect the two devices, RCA cables are frequently utilized. On sometimes, connected via an AUX wire. It is dependent on whether the speakers are powered or not.

Powered speakers must be connected to a separate power source in order to operate. This power supply is utilized by powered speakers to enhance the voltage and current of the line-level signal.

As a result, a Bluetooth receiver can be directly connected to a powered speaker system.

Additionally, a Bluetooth audio channel can be added to your powered speaker system by connecting the speakers to the preamp’s output channel and the Bluetooth to one of the preamp’s audio input channels.

A preamp might be a viable alternative for speakers that lack built-in volume controls. Preamplifiers are strongly suggested if your powered speakers lack a volume control. To prevent having to remember to adjust the volume each time you wish to listen, you should instead utilize a Bluetooth device.

How to connect a Bluetooth receiver to a pair of passive speakers

Passive technology speakers do not require a separate power source. With passive speakers, you must amplify the line level signal with an amplifier or A/V receiver.

The Bluetooth receiver may be directly attached to any available audio input channel. If you’re utilizing a power amp.

When connecting a Bluetooth receiver to a television set via an A/V receiver, you should select the HT Bypass or Direct In channel.

You can utilize HT Bypass or Direct In if you do not want your A/V receiver to be able to adjust the volume, gain, or EQ settings. This is because the Bluetooth gadget acts as a preamp.

If your A/V receiver does not offer HT Bypass or Direct In, you can still connect it to an empty audio channel. As a result, the sound quality of your Bluetooth device will be significantly reduced.

To prevent interfering with the volume settings of other devices, adjust the volume over Bluetooth.

Connections RCA and Auxiliary

The speakers themselves might be aggravating. Speakers typically have one of three connectors. Connecting a Bluetooth device to a TV is as simple as using RCA wires, as most Bluetooth receivers offer RCA outputs.

A converter cable will be required. If you’re using a Bluetooth receiver for your car audio system. Ascertain that the cable’s other end is linked to an aux port. Generally, aux female to left and right male RCA cables can be located.

If you have RCA-connected speakers. The method may be more challenging with clips or banana plugs.

Speaker Clips and Banana Plugs

Banana plugs are another option for connecting speakers. Similar to speaker clips, banana plugs have clearly identifiable positive and negative contacts.

Banana plugs have distinct plugs for positive and negative connections, in contrast to the majority of other connector types, which combine the two into a single plug. Two banana plugs are used in place of one RCA plug on RCA to banana plug connections.

Another form of connection you may discover is a speaker clip. Speaker clips with spring-loaded terminals allow bare wire in lieu of standard plugs. Speaker clips, like banana plugs, have distinct positive and negative terminals.

Cable Preparation for Speaker Wire

While RCA to speaker wire cables are commercially available, building your own is quite simple. Eliminate the plug from one end of a standard RCA cable. Remove a little section of the outer tube to uncover the device’s two wires.

By slicing a small length of tubing from both ends, connect one wire to the positive terminal and the other to the negative terminal.

The most challenging conversions are stereo aux connections and speaker clips. Stereo aux plugs integrate two channels into a single plug, in contrast to RCA plugs, which include only one positive and one negative wire.

Connect to a Bluetooth receiver

After connecting your Bluetooth receiver to your speakers, the difficult part is gone. Now you must pair your device with the Bluetooth receiver and complete the setup.

To begin, power on the Bluetooth device. After turning on your Bluetooth receiver, connect your powered speakers.

The next step is to pair your Bluetooth device. By enabling the Bluetooth feature on your mobile device, ensure that your device is connected to a Bluetooth receiver.

You should now be able to stream audio directly from your computer to your speakers.
