For precise audio/video syncing, the F4 utilizes a Temperature Compensated Crystal Oscillator (TCXO) that generates time code at 0.2 ppm accuracy—a first for this price point. The F4 supports all standard drop frame and non-drop formats, and can jam sync to time code provided by external devices. Standard BNC connectors enable easy integration into any rig. Advanced onboard limiters provide overload protection which lets you capture audio in a wide range of dynamic sound environments. Limiting can be applied to all four channels simultaneously at full resolution, with 10 dB of headroom and controls for setting threshold, attack, and release. A compact metal chassis makes the F4 both rugged and durable, and keeps its weight down to just 2.27 pounds without batteries. The F4 is outfitted with a 10-pin Zoom mic capsule input to expand your recording capabilities even further. Connecting the optional EXH-6 XLR/TRS Combo Input Capsule adds two extra mic/line inputs to your F4, giving you a total of six discrete XLR/TRS combo inputs. Use the proprietary Zoom capsule input to connect any of the available Zoom mic capsules—such as the SGH-6 Shotgun Mic Capsule or the XYH-6 Stereo X/Y Mic Capsule—to add an on-board microphone to your F4. The optional ECM extension cable allows for remote positioning of all capsules. An easy-to-read 1.9-inch white backlit monochromatic LCD display makes the F4 suitable for all lighting environments— from low light to direct sunlight. It also performs well in harsh conditions, like dusty and hard-to-see environments.
