The SASB-ET4F is designed for lighting technicians, sound engineers, and venue operators who need to run multiple XLR signals over long distances using standard network cable. This passive stage box adapter solves the problem of cable clutter and signal degradation over extended runs.

This adapter converts four XLR female connections into a single Ethercon RJ45 output, allowing you to transmit balanced analog, AES digital, or DMX lighting signals through one Cat5e, Cat6, or Cat6a network cable. The passive design requires no power and maintains signal integrity without introducing noise or distortion.

The unit handles four independent channels simultaneously, making it ideal for multi-microphone setups, lighting control runs, or mixed audio/DMX applications. The Ethercon connector provides a secure, lockable connection that won't accidentally disconnect during live events. All connections maintain proper impedance matching and balanced signal transfer.

Perfect for theaters running DMX to distant lighting positions, churches extending microphone signals from stage to sound booth, or recording studios routing multiple signals across large facilities. The adapter works effectively for runs up to several hundred feet when paired with quality network cable.

Connect your XLR sources to the four female inputs, then run a single Ethercon cable to your destination where a matching male-to-XLR adapter breaks out the signals. The compact metal housing withstands regular touring and installation use.

Seismic Audio backs this adapter with reliable performance for professional applications, plus fast shipping to keep your projects on schedule.

Frequently Asked Questions

What types of signals can I run through this adapter?

The SASB-ET4F handles balanced analog audio signals, AES digital audio, and DMX lighting control signals. Each of the four channels operates independently, so you can mix different signal types on the same unit - for example, running three microphone signals and one DMX line simultaneously.

How far can I extend signals using this adapter with network cable?

With quality Cat6 cable, you can reliably extend XLR signals several hundred feet without noticeable signal degradation. The exact distance depends on your signal type and cable quality, but typical installations handle 300-500 foot runs effectively for both audio and DMX applications.

Do I need a matching adapter on the other end of the network cable?

Yes, you'll need a complementary adapter that converts from Ethercon RJ45 back to individual XLR male outputs at your destination point. The network cable carries all four channels, but you need another breakout box to access the individual signals at your mixer, lighting console, or other equipment.

Can this handle phantom power for condenser microphones?

No, this is a passive adapter that doesn't pass phantom power through the network cable connection. If you need to power condenser microphones, the phantom power must be applied at the destination end after the signals are broken back out to individual XLR connections.

Is this better than running four separate XLR cables for long distances?

For runs over 100 feet, this system offers significant advantages including reduced cable bulk, lower cost for long distances, and better organization. Network cable is also more durable and easier to pull through conduit than multiple XLR cables, making it ideal for permanent installations.
