Cameo SB8.3 - Professional 8-Channel DMX Splitter/Booster

The Cameo SB8.3 is a professional device designed for configuring advanced DMX networks. This 8-channel splitter/booster in a 19" 1U format amplifies the incoming DMX signal and distributes it across 8 galvanically isolated outputs, ensuring stable and reliable distribution of control signals to multiple lighting devices simultaneously. It is an essential tool for every lighting designer, stage technician, and lighting system installer who requires secure and reliable DMX data transmission in complex installations.

Product Features

The Cameo SB8.3 features 8 galvanically isolated 3-pin XLR outputs located on the rear panel, guaranteeing complete electrical separation between individual DMX lines and protecting connected devices from mutual interference. The device is equipped with dual THRU inputs and outputs on both the front and rear panels, connected in parallel, allowing for convenient daisy-chaining of subsequent devices without needing to reach the rear panel. Bright LED indicators on the front panel provide real-time information on power status and the presence of a DMX signal on each channel, facilitating quick system diagnostics. A built-in switchable 120 Ohm terminating resistor for the DMX THRU output and a mains switch complete the device's comprehensive feature set.

Reliable DMX Signal Distribution for Demanding Installations

In complex lighting systems where many devices are connected to a single DMX console output, signal stability and quality are crucial. Overloading the DMX line can lead to transmission errors, flickering lights, or a complete loss of lighting control. The Cameo SB8.3 effectively solves this problem by amplifying the input signal and distributing it to 8 independent, galvanically isolated outputs. This ensures that each end device receives full signal strength, without the risk of overload or degradation of transmission quality, even in cases of very long cable runs.

Galvanic isolation of the individual outputs is one of the key advantages of this splitter. It protects connected devices from interference originating from other elements of the DMX network, eliminates issues related to ground loops, and prevents damage resulting from electrical potential differences between devices. This is particularly important in professional stage and studio installations, where the reliability of the lighting system directly impacts the course of an event.

The ability to connect the device directly to a DMX console or other DMX devices makes the SB8.3 suitable for both permanent installations in clubs, theaters, and concert halls, as well as mobile lighting systems used on concert tours and outdoor events. Dual THRU inputs and outputs on the front and rear allow for flexible cabling — the cable can be connected from the front or rear, depending on needs and workstation configuration. Mounting brackets can be attached to the rear of the device, enabling 180° inverted installation and ensuring easy access to all connectors.
