The SA-iERQM25 4-pack delivers reliable stereo connections between consumer devices and pro audio gear. DJs, mobile performers, and venue operators use these to bridge the gap between smartphones, tablets, and their PA systems or mixers.

These 25-foot cables handle stereo audio signals from 1/8" (3.5mm) outputs to 1/4" inputs, letting you connect phones, laptops, and MP3 players directly to mixing boards, powered speakers, or amplifiers. The TRS connections preserve left/right stereo separation for full-range playback.

Built with oxygen-free copper conductors, each cable maintains signal integrity across the full 25-foot length. The molded connectors provide secure connections that won't work loose during performances. At 25 feet, you get enough reach to position source devices away from the mixing position while keeping cables organized.

Mobile DJs use these to connect client devices for special requests or ceremony music. Churches and schools rely on them to patch smartphones and tablets into existing sound systems for presentations or background music. The 4-pack ensures you have backups ready and can handle multiple simultaneous connections.

Each cable connects any device with a standard headphone jack to professional audio equipment with 1/4" TRS inputs. The pack includes four identical 25-foot cables with matching connectors.

Every Seismic Audio cable ships with fast, reliable delivery and a one-year warranty covering manufacturing defects.

Frequently Asked Questions

What devices can I connect with these cables?

Connect any device with a standard headphone jack (smartphones, tablets, laptops, MP3 players) to professional audio equipment with 1/4" inputs like mixing boards, powered speakers, or amplifiers. The 1/8" end plugs into consumer devices while the 1/4" end connects to pro audio gear.

Will these cables work for both stereo music and mono signals?

Yes, these TRS cables handle both stereo signals (preserving left/right separation) and balanced mono signals. When connecting stereo sources like phones or tablets, you'll get full left/right channel separation through your PA system.

How many people can I reach with a 25-foot cable run?

The 25-foot length works well for small to medium venues up to 200 people, giving you flexibility to position source devices away from the mixing board or speakers. For larger venues, you may need longer runs or wireless solutions.

Do I need special adapters to connect my iPhone or Android device?

Most modern devices connect directly using the 1/8" end. However, newer iPhones without headphone jacks will need Apple's Lightning-to-3.5mm adapter, and some Android phones may require a USB-C to 3.5mm adapter depending on your device model.

Why buy a 4-pack instead of individual cables?

The 4-pack provides backup cables for critical events and allows multiple simultaneous connections. Mobile DJs often need to connect multiple devices, and having spares prevents show-stopping failures when cables get damaged or misplaced during setup.
