Air Sound & Vision manufactures a few products to help installers of automotive accessories. These have been developed after many years of experience in the automotive accessory installation field to solve specific needs that our installers have requested.
The ASV3270 is a battery operated hand held multi-tester for use by car audiovisual system installers. It comes with test leads, alligator clip, RCA to 3.5mm cable and a user manual. You will need to supply a standard 9V alkaline battery.
The ASV3222 is a neater, quieter and lower power solution to many installation tasks where relays and diodes might normally be used, but they can also solve many problems that may otherwise mean a job must be turned away.
