Sometimes in-built projector speakers are not enough!
Most of the projector users say that they don’t have good quality in-built speakers.
Few don’t have in-built speakers at all.
So nowadays, it is very common to use external devices like stereo speakers, soundbar and Home Theatre System, etc. to improve the sound quality.
Generally, there can be two ways of improving the sound quality,
- Replacing the in-built speakers
- Amplifying the in-built speakers
Fortunately a projector offers range of audio connectivity ports.
So, connecting a projector to the external audio device (to amplify the sound) is a breeze.
List of devices that you can connect to a projector
Before we proceed further, kindly note that the connectivity ports for a projector depends upon the manufacturer (brand).
We will discuss few generic ways of connecting external audio devices to the projector.
So without any further ado, let’s get started.
1. Stereo Speakers
In the stereo speakers system, a couple of speakers are connected.
A 3.5mm Audio Jack is used to connect such a sound system with other devices like a projector.
Make sure that your projector has a compatible 3.5mm Audio Jack to plug in the stereo speakers.
Some stereo speakers have individual left and right audio connectors coming out of them to experience high fidelity audio.
Many projectors have “R” and “L” input ports to accept sound signals from such connectors.
Soundbars are becoming very popular nowadays.
This type of sound system works on the amplification principle.
In contrast to the stereo speakers that turns OFF the in-built speaker completely and then generate sound through themselves, a soundbar doesn’t turn OFF the in-built projector speaker.
Sound is generated in sync with the projector’s in-built speakers. So, the soundbar is also known as the sound amplifier.
It comes with any of the following connectors,
- Dedicated left and right connector
- 3.5mm Audio Jack
- HDMI Audio Connector
Make sure that your projector has one of the above connectors.
3. Home Theatre System
It is a relatively hard to connect home theatre system to a projector.
It needs to be done in several different ways than discussed earlier.
You need be familiar with the following terms.
- AVR (Audio Video Receiver)
- Matrix Switch
AVR – It is also known as an Audio Video Receiver. Generally, it splits the cable into two and transmit audio signals to speakers and video signals to display.
Splitter: A Splitter splits the connection from one media device between two distinct devices like one audio device and one display device.
Switch – It lets you increase the number of devices that you can connect to the projector.
Matrix Switch: It is the combination of a Splitter and a Switch.
4. Bluetooth Speakers
Most of the modern projectors have in-built Bluetooth connectivity.
With such projectors, connecting Bluetooth speakers is a breeze.
Just navigate to the projector Bluetooth settings then try searching and pairing options.
Meanwhile, make sure that your speakers are not connected to any other Bluetooth device in your home.
Even if you fail to pair then try turning speaker’s Bluetooth ON and OFF several times. It will help you troubleshoot the intermediate induce detection.
If your projector doesn’t have in-built Bluetooth connectivity, you can also make it a Bluetooth-enabled device by using a Bluetooth Transmitter and Receiver Device.
You can find them easily on Amazon.
You might have realized that how easy it is to connect speakers to a projector, except in the case of a home theatre system, which requires extra efforts and knowledge.
For few people it may take 2-5 minutes to connect speakers to projector and others may have to struggle for around half-an-hour to get things right.
Understand that the difficulty level of connecting anything to a projector varies according to the projector’s brand.
But don’t worry if you have learnt the fundamentals mentioned in this article.
They will definitely help you!
