City Theatrical Image Multiplexer™ – Six Image Projection Accessory

City Theatrical Image Multiplexer™ – Six Image Projection Accessory for Source Four®

The City Theatrical Image Multiplexer™ is a creative beam control accessory designed for ETC Source Four® and other profile spotlights with a 6¼" colour frame slot. Using six precision prisms, it transforms a single projected image into six identical images, creating striking kaleidoscope-style effects, patterns and abstract projections.

Ideal for theatre, concerts, live events and creative lighting installations, the Image Multiplexer allows lighting designers to create complex visual effects from a single fixture. When combined with gobos, gobo rotators and coloured lighting filters, it can produce everything from subtle textures and scenic effects to dynamic moving projections.

Product Identification

Manufacturer: City Theatrical
Product: Image Multiplexer™
Part Number: 1450
Product Type: Multi-Prism Beam Control Accessory

How It Works

The Image Multiplexer uses six integrated prisms to split a single projected image into six separate images. Simply insert it into the fixture's standard 6¼" colour frame slot and the projected beam is transformed without requiring any modification to the lighting fixture.

When used with static or rotating gobos, the Image Multiplexer creates striking multi-image projections. Adding a rotating gobo introduces movement, creating even more dynamic and creative lighting effects.

Creative colour effects can also be achieved by attaching small pieces of different coloured lighting filters to the front of the Image Multiplexer. The coloured gels interact with the prism system to create blended colour variations across the projected images, allowing unique multi-colour effects from a single lighting fixture.

Creative Lighting Possibilities

Originally developed to create a kaleidoscope-style lighting effect, the Image Multiplexer has become a popular creative tool for lighting designers looking to produce complex effects from simple setups.

A single profile fixture combined with an Image Multiplexer, gobo and colour filters can create:

• Kaleidoscope-style projections
• Multi-image gobo effects
• Abstract textures and patterns
• Scenic and cyc projections
• Moving effects when combined with rotating gobos
• Unique colour blends using gel combinations

The Image Multiplexer encourages experimentation, allowing designers to create distinctive lighting effects without the need for multiple fixtures.
