Why is 48 inputs valuable for large audio systems?

The GX4816 handles large ensemble recordings, major festivals, complex broadcast productions, and professional rental applications where dozens of simultaneous microphones are required without external I/O expansion.

What is the advantage of 16 line outputs?

16 outputs support routing independent mixes to multiple destinations—main PA, broadcast feeds, wireless transmitters, recording systems, and more. This flexibility handles complex venue and production requirements.

How do the two DX ports expand capability further?

The DX ports allow connection of additional DX32, DX168, or DX164-W expanders, multiplying your input and output capacity beyond the base 48+16. This supports the largest installations and touring rigs.

Does the GX4816 work with SQ, Avantis, and dLive systems?

Yes, the GX4816 is compatible with SQ, Avantis, and dLive mixing consoles, providing I/O expansion via EtherCon connectivity.

What does the 5U rack chassis provide for installations?

The 5U form factor fits standard server racks for permanent and touring installations. The compact, rugged design withstands repeated transport and setup cycles.

What sample rate support does the GX4816 offer?

The GX4816 operates at up to 96 kHz, delivering professional broadcast and live sound audio quality across all 48 inputs and 16 outputs.
