Bringing your favorite movies, shows, and presentations to life on a big screen is a fantastic experience. However, the built-in speakers on many projectors, including popular Onn models, often leave something to be desired. To truly elevate your viewing or presentation with rich, room-filling sound, connecting external speakers is a game-changer. This guide will walk you through every step, from identifying the right connection types to troubleshooting common issues, ensuring you get the most out of your Onn projector’s audio capabilities.
Understanding Your Onn Projector’s Audio Output Options
Before you can connect external speakers, it’s crucial to understand what audio output ports your specific Onn projector model offers. Most modern projectors, including Onn’s lineup, typically provide one or more of the following audio output options:
3.5mm Audio Jack (Auxiliary Output)
This is perhaps the most common and versatile audio output you’ll find on an Onn projector. It’s a standard 3.5mm (1/8-inch) stereo mini-jack, identical to the headphone jack on most smartphones, laptops, and portable audio devices.
- How it works: This jack transmits an analog stereo audio signal.
- What you’ll need: A 3.5mm male-to-male audio cable. These are widely available and inexpensive.
- Pros: Universal compatibility with a vast range of audio devices, simple plug-and-play operation.
- Cons: Can sometimes be susceptible to interference if the cable is low quality or runs alongside power cords. The audio signal is analog, which can sometimes result in slightly lower fidelity compared to digital outputs.
HDMI ARC (Audio Return Channel)
Some higher-end or more recent Onn projector models might feature HDMI ARC. This is a more advanced connection that allows audio to be sent from the projector back to an audio device (like a soundbar or AV receiver) through the same HDMI cable that carries video.
- How it works: HDMI ARC leverages a specific HDMI port (often labeled “ARC” or “HDMI 1 ARC”) to carry both video signals to the projector and audio signals back to a compatible audio system.
- What you’ll need: An HDMI cable that supports ARC (most modern HDMI cables do, but it’s good to check specifications), and an audio device (soundbar, AV receiver) with an HDMI ARC-compatible port. Both devices must be set to enable ARC in their respective settings menus.
- Pros: Single cable solution for both video and audio, supports higher quality audio formats (like Dolby Digital, DTS), can offer better audio synchronization.
- Cons: Requires both the projector and the audio device to support HDMI ARC, can sometimes be finicky to set up if not configured correctly.
Optical Audio Output (Toslink)
While less common on entry-level Onn projectors, some models might include an optical audio output. This digital connection uses a fiber optic cable to transmit audio signals.
- How it works: Toslink cables carry digital audio data, which is converted to analog by the receiving audio device.
- What you’ll need: An optical audio cable (Toslink cable) and an audio device with an optical audio input.
- Pros: Pure digital signal transmission, less susceptible to electrical interference than analog cables, can support various surround sound formats.
- Cons: Requires a specific cable type and compatible ports on both devices, the cable can be slightly less flexible than a 3.5mm cable.

What types of audio outputs does the Onn projector typically have for connecting speakers?
The Onn projector generally offers a standard 3.5mm audio output jack, which is the most common and versatile connection method. This port resembles a headphone jack and is designed to accept analog audio signals from the projector to your external speakers or soundbar.
In addition to the 3.5mm jack, some Onn projector models might also feature an HDMI ARC (Audio Return Channel) port. If your projector and sound system both support HDMI ARC, this offers a more advanced and potentially higher-quality audio connection, consolidating both video and audio through a single HDMI cable.
Can I connect Bluetooth speakers directly to the Onn projector?
Yes, many Onn projector models come equipped with Bluetooth connectivity, allowing you to pair compatible wireless speakers directly. To do this, you’ll typically need to access the projector’s settings menu, navigate to the Bluetooth options, and initiate a pairing process to discover and connect to your chosen speakers.
The process usually involves putting your Bluetooth speakers into pairing mode, then selecting them from the list of available devices on the projector. Once paired, the projector will send its audio output wirelessly to the connected Bluetooth speakers, offering a convenient, cable-free audio experience.
What is the best way to connect wired speakers to the Onn projector if it only has a 3.5mm audio out?
If your Onn projector only features a 3.5mm audio output, the most straightforward way to connect wired speakers is by using a 3.5mm male-to-male audio cable. This cable will plug directly into the projector’s audio out port on one end and into the auxiliary input (AUX IN) on your speakers or soundbar on the other.
Ensure that the 3.5mm audio cable you use is of good quality to minimize any potential signal degradation. Most powered speakers or soundbars will have a dedicated AUX IN port, making this connection simple and effective for delivering audio from the projector.
Are there any special considerations for connecting a soundbar to an Onn projector?
When connecting a soundbar, the primary consideration is the type of input the soundbar offers and the corresponding output on your Onn projector. If your soundbar has a 3.5mm AUX input, a standard 3.5mm audio cable will suffice. For potentially better audio quality and a cleaner setup, look for HDMI ARC compatibility on both the projector and the soundbar.
If your projector doesn’t have HDMI ARC but your soundbar does, you might be able to use the soundbar’s optical audio input. In this case, you would need an HDMI to Optical converter or an optical audio cable if your projector happens to have an optical output, although this is less common on Onn projectors.
What audio settings should I adjust on the Onn projector after connecting speakers?
Once your speakers are connected, you will likely need to adjust the audio output settings within the Onn projector’s menu. This usually involves navigating to the ‘Audio’ or ‘Sound’ section and ensuring that the output is set to the correct port or connection type you are using (e.g., ‘External Speakers,’ ‘Audio Out,’ or ‘Bluetooth’).
You may also find options to adjust the volume levels, audio format (like stereo or surround sound if supported), and sometimes even EQ settings to optimize the sound for your room and speaker setup. It’s advisable to experiment with these settings to achieve the best possible audio performance.
What troubleshooting steps can I take if I’m not getting any sound from my connected speakers?
If you’re not hearing any sound, the first step is to double-check all physical connections to ensure they are securely plugged into both the projector and the speakers. Verify that the speakers themselves are powered on and that their volume is turned up. Also, confirm that the projector’s volume is not muted or set to the lowest level.
Next, review the projector’s audio output settings to ensure the correct output source is selected. If using Bluetooth, confirm the speakers are successfully paired and connected. If using cables, try a different audio cable or test the speakers and projector with another device to isolate the source of the problem.
Can I connect multiple sets of wired speakers simultaneously to the Onn projector?
Generally, a single 3.5mm audio output on the Onn projector is designed to send an audio signal to one primary audio device, such as a single pair of powered speakers or a soundbar. Attempting to connect multiple separate wired speaker systems directly to this single output without proper amplification or splitting equipment will likely result in a weak or distorted audio signal and may even damage the projector’s audio output.
If you wish to connect multiple wired speakers, you would typically need an external audio splitter or amplifier that takes the single 3.5mm output from the projector and then distributes the signal to multiple speaker inputs. This would allow you to power and manage the audio for a more expansive sound system.
