Sennheiser ASP 212 Dual Two-Way BNC Passive Splitter with DC Pass-Through

Passive dual two-way antenna splitter for cascading up to 16 receivers with DC power pass-through

The Sennheiser ASP 212 is a dual two-way passive splitter box with BNC connections and DC pass-through, designed for building cascaded antenna distribution systems that can serve up to 16 wireless receivers when combined with two 8-channel splitter kits. The dual design handles both diversity antenna paths (A and B) in a single unit, simplifying the cascading architecture.

The DC pass-through feature is critical for systems using active antennas or boosters that receive their power via DC bias on the coaxial cable from the receiver. Without DC pass-through, the passive splitter would block the DC voltage and prevent active antennas from powering up. The ASP 212 passes DC through to the antenna side, maintaining compatibility with active antenna components in the signal chain.

Key Features

• Dual two-way passive splitting for both diversity antenna paths
• DC pass-through for active antenna and booster compatibility
• BNC connections throughout
• Cascadable with 8-channel splitter kits for up to 16 receivers
• Passive design requires no external power for the splitter itself
• Single unit handles both antenna A and antenna B paths

Professional Applications

Commonly deployed in church, house of worship, and professional AV environments.

• Cascaded antenna distribution systems for large wireless deployments
• Expanding existing 8-channel splitter systems to 16 channels
• Systems using active antennas that require DC bias pass-through
• Multi-rack wireless installations in venues and broadcast facilities

Frequently Asked Questions

What does DC pass-through mean?

DC pass-through allows the DC bias voltage from the receiver to travel through the splitter to the antenna side of the cable. This is necessary when using active antennas or boosters that are powered via the coaxial cable rather than a separate power supply.

Can I use the ASP 212 without the 8-channel splitter kits?

The ASP 212 is a two-way splitter that doubles the number of outputs from another splitter. It is designed to be cascaded with splitter kits. Used alone, it provides a basic two-way split of each antenna path.

Related Equipment and Workflow Compatibility
