The SAPT63 adapter connects balanced 1/4" TRS outputs to XLR inputs, solving interface mismatches between professional audio gear. Musicians and audio engineers need this adapter when connecting keyboards, audio interfaces, or effects processors with TRS outputs to mixing consoles, powered speakers, or recording equipment with XLR inputs.

This adapter maintains balanced audio signal integrity while bridging the connector gap between different professional audio standards. The TRS female connector accepts standard 1/4" balanced cables, while the XLR male output connects directly to microphone inputs on mixers and audio interfaces.

Built with professional-grade connectors and internal wiring, the SAPT63 handles line-level signals without introducing noise or signal degradation. The compact design adds minimal bulk to your signal chain, making it ideal for live sound setups where space and reliability matter. At just 0.10 lbs, it won't add noticeable weight to your gear bag.

Recording studios use this adapter to connect outboard gear to console inputs, while live sound engineers rely on it for connecting keyboards and DJ mixers to PA systems. It's essential for mobile DJs who need to interface consumer and semi-pro gear with professional sound systems at venues and events.

Simply connect your balanced 1/4" TRS cable to the female end and plug the XLR male connector into your destination device. The adapter maintains the balanced connection throughout the signal path, ensuring professional audio quality.

Seismic Audio backs the SAPT63 with a one-year warranty and ships fast from our warehouse. Professional connectivity shouldn't cost a fortune.

Technical Specifications

Frequently Asked Questions

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

This adapter specifically uses a TRS (Tip-Ring-Sleeve) female connector, which carries balanced audio signals with three connection points. TRS connections reduce noise and interference compared to TS (Tip-Sleeve) unbalanced connections. If you're connecting unbalanced equipment, the adapter will still work but you'll lose the noise rejection benefits of balanced audio.

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

Yes, this adapter is perfect for connecting keyboards with balanced 1/4" outputs to mixing console XLR inputs. Most professional keyboards and stage pianos have balanced TRS outputs, and this adapter lets you run those signals into the XLR microphone inputs on your mixer while maintaining the balanced connection for better sound quality.

Will this adapter work for connecting audio interfaces to powered speakers?

This adapter works when your audio interface has balanced 1/4" TRS outputs and your powered speakers have XLR inputs. However, check your signal levels - some audio interfaces output at line level while some powered speakers expect microphone level signals. You may need to adjust gain settings on your speakers to match the signal levels properly.

Do I need any additional cables to use this adapter?

You'll need a standard balanced 1/4" TRS cable to connect to the female end of the adapter. The XLR male end plugs directly into your destination equipment. Make sure to use a balanced TRS cable rather than an unbalanced TS guitar cable to maintain the signal quality benefits this adapter provides.

Can this adapter handle phantom power from mixing console inputs?

This adapter will pass phantom power from XLR inputs back through the TRS connection, but most line-level equipment with TRS outputs is not designed to receive phantom power. Always turn off phantom power on the mixer channel when using this adapter to avoid potential damage to your connected equipment.
