The SALWR4M is built for DJs, bands, and sound engineers who need reliable protection for their rack-mounted gear without the bulk and weight of traditional flight cases. This 4-space rack case protects wireless mic receivers, preamps, power conditioners, and other essential equipment while keeping your load-in manageable.

The lightweight ABS construction with aluminum rails delivers professional-grade protection at a fraction of the weight of wooden or metal alternatives. The 12-inch depth between rails accommodates most standard rack gear, while the front and rear removable doors provide quick access during setup and performance.

Key dimensions include 7 inches of vertical mounting space across 4U, standard 19-inch rail width for universal compatibility, and 14.5 inches from front rail to back wall with the rear door on. The heavy-duty butterfly latches secure your gear reliably, while dual spring-loaded handles on each side make transport comfortable for one person.

DJs use this case for wireless mic systems and lighting controllers at weddings and corporate events. Bands rely on it for in-ear monitor transmitters and effects processors during club gigs and festival runs. Churches and schools find it perfect for protecting audio interfaces and small mixers in permanent installations.

The case includes all mounting screws and washers needed to install your gear. One rear door features an interior screen pocket for cable storage or documentation.

Seismic Audio backs the SALWR4M with a one-year warranty and ships it ready to protect your investment from day one.

Technical Specifications

Frequently Asked Questions

What type of equipment fits in this 4U rack case?

The SALWR4M accommodates most standard 19-inch rack-mounted equipment up to 12 inches deep, including wireless microphone receivers, preamps, power conditioners, effects processors, audio interfaces, and small mixers. The 4U height provides 7 inches of vertical mounting space. Equipment deeper than 12 inches between mounting rails will not fit properly.

How much weight can this rack case hold?

While Seismic Audio doesn't specify a maximum weight limit, the lightweight ABS construction is designed for typical rack gear like wireless systems and preamps rather than heavy power amplifiers. For reference, most wireless mic receivers and preamps weigh 3-8 pounds each. If you need to transport heavy amplifiers, consider Seismic Audio's flight case options instead.

Is this rack case suitable for touring and transport?

Yes, the SALWR4M is designed for regular transport with heavy-duty butterfly latches, dual spring handles, and protective ABS construction. However, it's a mid-duty case rather than a flight case, making it ideal for local gigs, church services, and regular transport where extreme protection isn't required. The lightweight design makes load-in much easier than traditional wooden cases.

What's the difference between this and a flight case?

This ABS rack case prioritizes portability and everyday protection, while flight cases offer maximum protection for harsh touring conditions. The SALWR4M weighs significantly less, costs less, and handles normal transport well. Flight cases use heavier materials and reinforced corners for airline travel and extreme conditions. Choose this for regular gigging; choose flight cases for touring or checked airline transport.

Do the doors need to stay on during use?

No, both front and rear doors are completely removable for performance use or permanent installations. Many users remove the front door during shows for easy access to controls while keeping the rear door on for cable management. The rear door includes a convenient screen pocket for storing cables or documentation when removed.
