About the STD-600

The RDL STD-600 is a passive audio divider-combiner designed for 600-ohm balanced audio systems. It splits one balanced audio input to two balanced outputs, or combines two balanced inputs to one balanced output, making it ideal for routing and mixing in professional audio installations.

With its transformer-based passive design, the STD-600 requires no external power and maintains signal integrity across broadcast, post-production, and enterprise AV applications. The rugged construction and compact form factor make it suitable for rack mounting or portable use in field installations.

Perfect for system integrators, broadcast facilities, and audio engineers who need reliable, passive impedance matching and signal distribution without active electronics or added noise.
