Compoline LED is a light effect system developed in collaboration by Hartwall Arena and ICEPRO that is integrated into the audience shield. It is part of the arena's world-class lightshow, and was integrated to the rink in the full update that was done in summer 2014. The existing ICEPRO STEELINE rink was updated with high-safety Compoline LED arena shields, the support beams of which were fitted with a LED media surface developed in collaboration with Studiotec. As the purpose of the update was to make the arena more versatile, the new rink is also very fast to install and to dismantle.

The light effect surface is integrated into the support structures of the arena shields and is visible both to the audience and to the ice. Every individual pixel of the Compoline LED system can be controlled separately. They can be used to produce multi-colour light effects, or the media surface can be used for playback of digital and analogue video images.

The new rink at the Hartwall Arena is Europe's first premium-level flexible rink, and meets the high standards set for player and audience safety as well as demanding usability, versatility and appearance requirements.

The media solution integrated to the ICEPRO high-safety rink is based on a novel video solution created by Martin Professional that is controlled using a system called P3 also developed by Martin. The system consists of LED strips, power supply units and a system processor. The system processor is connected to the power supply units using a single cable that carries both power and control data. If the capacity of one system processor is not sufficient, several processor units can be used in parallel.

As the system processor has a graphic user interface, configuring the settings is easy. A graphic user interface is used to perform video mapping, adjust media surface and monitor the system. Key controls, such as brightness and video mapping, can also be controlled in real time using the processor's user interface or through DMX light control signals.

The system is safe both to the players as well as the audience, and makes it possible to create completely new kinds of experiences in hockey matches.
