BSS AC-5S-WH - Analog Wall Controller with 5-Position Source Selector (White)

The BSS AC-5S-WH is an analog wall controller from the Soundweb Contrio family, designed to give each zone clear and reliable source selection control via a 5-position rotary switch. It integrates directly with BSS Soundweb London processors via its GPI (Control Inputs) and can be configured in minutes from HiQnet Audio Architect (or London Architect ) using drag-and-drop operations. This white version is available in both US Decora and EU single-gang formats for a clean, standardized installation.

The AC-5S uses a 5-step resistor ladder network , ideal for source selection or preset recall . Each unit consumes only 1 GPI input , so a typical Soundweb London chassis can support up to 12 AC-5S controllers , expandable to 36 using the BLU-GPX expander. For reliability and safety, BSS recommends VW-1 wiring with a 5V / 1mA reference. The connection is 2-wire (signal and ground) and is the default mode on the processors.

The front panel allows for labeling of each position thanks to a removable lens window , so the sources can be identified on the wall. European versions include 3 mm and 3.5 mm screws to fit standard EU boxes. Also available in a black finish .

Main features

• 5-position rotary selector with ladder resistor , perfect for source selection or preset recall.
• Direct integration with Soundweb London processors via GPI (Control Inputs).
• 1 GPI per controller ; up to 12 units per chassis and 36 with BLU-GPX expander.
• Easy configuration in Audio Architect / London Architect via drag-and-drop .
• Single-gang mounting in US Decora and EU versions, white finish (also available in black).
• 2-wire connection (signal and ground) to the GPI port; 2-wire mode is enabled by default on the processor.
• Label window under removable lens to identify positions on the front.
• Recommended wiring : VW-1, reference 5 V / 1 mA .

Product benefits

• Intuitive Operation : 5-step rotary knob reduces the learning curve for non-technical users.
• Reduced complexity : analog control without additional networking or protocols; high reliability in professional environments.
• Zone scalability : By requiring only 1 GPI, it is easy to add multiple selection points to an installation.
• Standardized finish and format : US/EU versions for compatibility with common flush-mount boxes.
• Clear labeling : The integrated window allows you to identify each source directly on the device.

Use cases

• Meeting and conference rooms: Quick switching between sources (VC, BYOD, player, HDMI, etc.).
• Education: Ticket selection in classrooms and auditoriums without accessing the rack.
• Hospitality and retail: selecting ambient music by area and recalling presets.
• Cultural spaces and places of worship: recovery of predefined scenes for different events.

Frequently Asked Questions

• How many AC-5s can I connect to one processor? Up to 12 controllers per typical Soundweb London chassis; up to 36 using the BLU-GPX expander.
• How do I wire it? Two wires (signal and ground) to a GPI input configured for 2-wire (default).
• Can I label fonts on the front? Yes, the front lens is removable so you can insert a label card with the font names.
• Does it include hardware? Yes. The EU versions include 3 mm and 3.5 mm screws for mounting in standard European boxes.
