PROEL AT170 - 6.3mm Stereo Audio Splitter Adapter (1 Male to 2 Female)
Maximize the connectivity and versatility of your sound setup with the Proel AT170 , a professional audio splitter adapter designed to duplicate signals with absolute integrity. This compact device is the ultimate solution for musicians, sound engineers, and audiophiles who need to convert a single 6.3 mm (1/4") jack output into two identical female jacks, allowing the simultaneous connection of two devices without the need for additional mixing consoles or complex cabling.
Manufactured to the rigorous standards of the renowned Italian brand Proel, the AT170 stands out for its reliability in critical situations, from studio sessions to live performances. Its body is constructed from high-strength ABS , an engineering thermoplastic polymer that offers exceptional durability against impacts, drops, and the wear and tear of daily stage use. Unlike generic, low-quality adapters, the molded chassis design ensures that the internal components are protected from mechanical stress.
From a technical standpoint, this adapter guarantees clean signal transmission thanks to its precision connectors. As a TRS (Tip-Ring-Sleeve) device, it is fully compatible with stereo and balanced signals, ensuring that the sound image remains faithful to the original source. Its ergonomic, cable-free (block-type) design facilitates integration into pedalboards, racks, or headphone outputs, offering a firm and secure connection that minimizes the risk of unwanted noise or accidental disconnections.
Main Features
-
Robust ABS Construction: Outer casing made of high-impact acrylonitrile butadiene styrene (ABS), providing a solid and lightweight structure immune to corrosion.
-
Full TRS Connectivity: Designed with a three-pole configuration (Tip-Ring-Sleeve) that allows the passage of complete stereo signals or balanced mono signals without loss of information.
-
Efficient Signal Duplication: Converts one male output into two female outputs in parallel configuration, ideal for "cloning" the audio signal to two destinations.
-
Nickel-Plated Contacts: The contact surfaces have a nickel coating that optimizes electrical conductivity and resists long-term oxidation.
-
Compact and Portable Design: Its reduced form factor eliminates the clutter of "Y" cables, making it easy to carry in any instrument case or pocket.
-
Secure Retention: The female sockets are calibrated to provide a firm grip when connecting the jacks, preventing cables from coming loose due to vibrations or slight tugs.
Product Benefits
The main value of the Proel AT170 lies in its ability to solve connectivity problems instantly and cost-effectively. Being a completely passive, plug-and-play device, it requires no batteries or external power; simply plug it in and it works.
For the user, this translates into the freedom to share their music or monitor without technical barriers. It maintains audio quality without coloring the sound, ensuring that what goes in is exactly what comes out in both directions. Furthermore, its ABS construction is not only durable but also acts as an effective electrical insulator for the adapter body.
Use Cases
-
Shared Monitoring (Headphone Splitter): Allows you to connect two pairs of professional headphones to a single output of a console or interface, making it easier for the engineer and the musician to listen to the same mix.
-
Music Education and Teaching: An essential tool in academies so that teachers and students can connect to the same digital piano or electronic drum kit without disturbing others.
-
Live Signal Routing: Ideal for sending the stereo output of a synthesizer or keyboard to two different destinations, for example, one to the stage amplifier and the other to a DI box for the mixing console.
-
Auxiliary Output Expansion: Useful in home studios to duplicate a line output and send the signal to different effects processors or external recorders simultaneously.
Frequently Asked Questions
-
Does the adapter split the signal into Left and Right (Mono) channels?
No. The AT170 is a splitter. The incoming stereo signal is copied identically to both outputs. You'll have two stereo outputs, not two separate mono outputs.
-
Can I use it with mono (TS) instrument cables?
Yes. Although the adapter is stereo (TRS), it is mechanically compatible with mono (TS) connectors. In this case, it will simply duplicate the mono signal on both outputs.
-
Does connecting two headphones affect the volume?
Because it's a passive adapter that connects two loads in parallel, the overall impedance is low. Depending on the power output of your headphones, you might notice a slight decrease in volume, which is normal in audio physics, but it generally remains perfectly functional.
-
Does it work for microphone inputs?
Technically, it allows you to connect two microphones to one input, but it's not recommended . Connecting two microphones in parallel can cause impedance problems and signal degradation. It's primarily designed for outputs (headphones, line).
