Built for both bench diagnosis and road testing, the kit includes extension jumpers, color-coded boots, straps and a charging station to keep transmitters secure and powered while you isolate the source of an intermittent sound.\n\n\u003ch3\u003eHow does the ChassisEAR 2 make finding noises faster?\u003c\/h3\u003e\n\u003cp\u003eThe system lets you place up to four microphone clamps in different locations and listen to each on a single receiver. You can mute or solo any transmitter and switch channels on the fly, which saves time compared with moving a single probe around the vehicle.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFour independent transmitters monitor multiple components simultaneously\u003c\/li\u003e\n  \u003cli\u003eSelectable channels allow instant comparison and isolation of noises\u003c\/li\u003e\n  \u003cli\u003eColor-coded boots and on-screen location naming speed identification\u003c\/li\u003e\n  \u003cli\u003eOver-ear headphones deliver clear audio for precise listening\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use it during road tests and in tight spaces?\u003c\/h3\u003e\n\u003cp\u003eYes — the ChassisEAR 2 is built for in-vehicle use while driving or idling.
