Reliable expert AV assistance.

Our team of expert AV technicians are ready to help. 

Crossover prides itself on offering a first-class, responsive, personal and caring support service. We provide peace of mind to the customers we serve, and ease the pressure on their in-house support teams whenever AV challenges arise.


End-user Training

If your staff don’t know how to get the most from your AV systems, your business can’t reap their full benefits. Crossover offers one-off or ongoing end-user training with all our AV installations. Our trainers work hard to engage staff and ensure they can exploit their new tools’ utmost potential. We help IT and facilities managers familiarise too, teaching them common troubleshooting processes, and create client-bespoke user guides.

AV Support & Preventative Maintenance Contracts

Not every business has the resources to maintain their AV systems, so we offer comprehensive support, including all-important preventative maintenance to maximise the life of your technology – whether we installed it or not. Tailoring an agreement to each client’s precise needs, we provide guaranteed service levels to many businesses, can agree to keep stock of key spare parts, and will always assign technicians who know your specific systems inside out.

AV Events Technicians

One-off events incorporating AV systems can be make or break moments for businesses and brands, so absolute confidence in your equipment and presentation systems is critical. Crossover can provide specialist AV events technicians who not only have rock-solid technical expertise but are also highly experienced in the diplomatic interpersonal skills which are essential in this high-pressured environment. Many clients retain our services on an ongoing basis with a contractual Events Support Agreement.
