ZeroNoise Pit-Link GSM ClearVoice™ Digital Circuit Intercom Amplifier

Revolutionise your pit-to-car strategy with the completely re-engineered ZeroNoise Pit-Link GSM Digital Amplifier. Purpose-built for high-pressure circuit racing and endurance motorsport, this system completely bypasses traditional radio setups by integrating a dedicated GSM cell module directly into the amplifier. By inserting a SIM card, the amplifier functions as an ultra-stable mobile phone network hub, delivering seamless pitlane communication even in areas where radio frequencies suffer from severe dead spots and interference.

The Pit-Link GSM is rated to IP65 dustproof and moisture-resistant standards, featuring a 36% larger high-contrast digital display for effortless monitoring on the fly. Driven by adaptive ClearVoice™ sound algorithms, the internal digital processor actively strips away background exhaust resonance and extreme cabin vibration to isolate crisp human speech. Calls from the pit crew open automatically to prevent driver distraction, or they can be managed manually using a steering wheel-mounted Push-To-Talk (PTT) button loop. With integrated panel-mounted Nexus sockets replacing flimsy in-line wiring, dual independent volume controls, Bluetooth configuration via the ZeroNoise App, and a dedicated camera audio-out port, it stands as the ultimate circuit racing communication hub.

Frequently Asked Questions (FAQ)

Q: How does the GSM pit-to-car communication function work?

A: Instead of using traditional radio transceivers, you insert a standard mobile network SIM card directly into the amplifier unit. The pit crew simply dials the helmet's dedicated mobile number. The amplifier can be set to answer the incoming call automatically, establishing a stable, encrypted, hands-free voice bridge over the cellular network.

Q: Can I use a Push-To-Talk (PTT) button with this unit?

A: Yes. The Pit-Link GSM supports both automated constant-open voice paths and manual communication. If preferred, you can connect an optional ZeroNoise steering wheel PTT button to give the driver complete control over exactly when their voice is transmitted back to the pit wall.

Q: Which helmet kits are correct for this specific amplifier?

A: The Pit-Link GSM features high-strength panel-mounted Nexus sockets. It is fully compatible with all Bell circuit helmets, ZeroNoise headsets, and standard 4-pin male Nexus helmet microphone kits (such as those configured with standalone RCA or 3.5mm earplug jacks for racing monitors).
