What does analog DC voltage logic control mean, and why does it matter?

Analog DC voltage logic sends control signals without digital processing, eliminating latency and artifacts. This gives you immediate, transparent zone switching ideal for live sound and professional installations where response time and audio purity are critical.

How far can I run cables from the ZC4 to other devices?

Cable runs extend up to 1000 feet using the optional ZC-BOB parallel wiring configuration, 600 feet with three controllers, or 300 feet with six controllers. All runs use CAT5 or CAT5E cables rated VW-1 or higher.

Do I need software or a touchscreen to set up the ZC4?

No. DIP switches provide all device identification and configuration, eliminating the need for complex software or external control interfaces.

What connectors does the ZC4 use?

The ZC4 has two RJ-45 jacks for network connectivity and one 6-pin phoenix terminal for additional control connections, all supporting standard CAT5/CAT5E cabling.

What are the physical dimensions and weight?

The ZC4 measures 6.8 x 5.5 x 3.4 inches and weighs 0.8 lb, making it compact enough for seamless wall-mount installation in any venue or studio.

dbx ZC4 Wall-Mounted Zone Controller

The dbx ZC4 delivers straightforward, hands-on control over multi-zone audio systems with a clean wall-mounted form factor that keeps your interface visible and accessible. Its responsive analog DC voltage logic control gives you immediate, transparent command over zone management without the latency or complexity of digital systems. This controller is built for studio operators and installers who need reliable, artifact-free performance across distributed audio environments—whether managing live recording spaces, multi-room monitoring setups, or networked session infrastructure.

Connectivity & Installation

The ZC4 connects via two RJ-45 jacks and a 6-pin phoenix terminal, supporting CAT5 or CAT5E cables rated VW-1 or higher with 28.6 Ohm/M nominal DCR. Cable runs extend up to 1000 feet with parallel wiring using the optional ZC-BOB, or up to 600 feet with three controllers and 300 feet with six controllers, making it flexible for installations ranging from small multi-room monitoring to large distributed studio systems.

Control Architecture & Build

DIP switches provide straightforward device identification, eliminating the need for complex configuration software or touchscreen navigation. The compact black chassis measures 6.8 x 5.5 x 3.4 inches and weighs just 0.8 lb, fitting seamlessly into wall-mount installations, while dual safety certifications (UL 60065, IEC 60065, EN 55013, E60065) ensure reliability in professional studio environments.
