Technical Specifications

Frequently Asked Questions

What's the difference between TRS and TS connections for this adapter?

The SAPT18 uses a 1/4" TRS (tip-ring-sleeve) male connector, which carries balanced stereo or mono signals with three contact points. This provides better noise rejection than TS (tip-sleeve) connectors and maintains signal integrity when connecting to professional XLR equipment. The TRS configuration makes this adapter suitable for both balanced mono and stereo applications.

Can I use this adapter to connect my keyboard to a mixing board?

Yes, the SAPT18 is perfect for connecting keyboards, synthesizers, or other instruments with 1/4" TRS outputs directly to XLR inputs on mixing boards or audio interfaces. This eliminates the need for separate cables and provides a clean, professional connection that maintains audio quality throughout your signal chain.

Will this adapter work with microphone preamps and audio interfaces?

Absolutely. The SAPT18 allows you to connect any device with a 1/4" TRS output to XLR inputs found on most professional preamps, audio interfaces, and mixing consoles. This is particularly useful in home studios where you need to connect consumer gear to professional recording equipment.

Does this adapter affect audio quality or introduce noise?

The SAPT18 uses high-quality connectors designed to maintain signal integrity without introducing noise or signal degradation. The solid construction and proper shielding ensure clean audio transfer, making it suitable for both live sound applications and critical studio recording environments.

What cable do I need to use with this adapter?

You'll need a standard 1/4" TRS cable to connect your audio source to the SAPT18 adapter. The adapter then plugs directly into any XLR female input on your mixer, interface, or other professional audio equipment. No additional cables or power supplies are required.
