Why use a comparator?
A comparator system allows sales people to instantly compare many different products, with the minimum of fuss and the highest degree of professionalism. Once a comparator is installed you no longer need to physically disconnect and reconnect equipment, wasting your customers and your own valuable time. This allows for either a more relaxing and organised consultation with one important customer, or many organised consultations at busy times.

Types of comparators
Comparators fall into two broad categories:

Electro Mechanical
Electro Mechanical comparators use interlocking mechanical switches. These switches are rarely designed for use in an audio signal path, which means they degrade the quality of the signal and reduce sound quality. This type of comparator uses large amounts of cabling that has to run to the rear of the control surface; further reducing the signal quality, increasing the costs of installation and making the system configuration more complex and harder to use.

Electronically Controlled
Nexus Sound and Vision Comparators are Electronically Controlled devices that use state of the art microprocessors and high quality relays to switch the signal path. This type of comparator offers better sound and vision quality, reduces costs and simplifies the system configuration making it easier to install and operate.

Using relay’s means Nexus Comparator’s can be used remotely; which means the signal cabling remains closer to the equipment being switched. This significantly improves signal quality as well as reducing the amount of cabling used in the system.
