Intercom Sparco IS-200 Nexus Female

The Sparco IS-200 is a good entry-level racing/rally intercom that gives you what you need to communicate with your co-driver/passenger.
Unlike the more expensive models from Sparco, the Sparco IS-200 has no ability to connect a mobile phone or an extra radio, however you can route the audio from the intercom out to your camera (via RCA connector).

The intercom amplifier from Sparco has two separate volume controls, one for the driver and one for the passenger.
Powered via the car's 12V system, or via a separate 9V battery (placed in the intercom amplifier).
Connects to your helmet/headphones with Nexus "Female" connectors.
Prepared for mounting on both flat surfaces and tube/round surfaces, mounting hardware included.
