Feature: 1. Dual Modes & Dual Channels: VM40 adopts Comica's patented technology of shotgun microphone integrated wireless RF module, which supports wired and wireless dual modes in sync. Besides, in wireless mode, the receiver supports single-channel or dual-channel recording, providing a more flexible solution for professional recording. 2. Up to 200M Working Range: The wireless transmission distance is up to 200min an open area and is stable without dropouts. Less than 20ms latency makes the audio transmission high efficient and synchronized with the video. 3. 14mm Gold-plated Capsule & 48K/32bit Float Recording: 14mm gold-plated mic capsule adopts super cardioid polar pattern to accurately pick up original sound and avoid the surrounding noise, presenting fuller, brighter, and crisper high-fidelity sound quality. 48kHz/32-bit float recording provides extremely high audio quality and dynamic range. 4. 32GB ON-board Storage: The built-in 32GB storage can store up to 40 hours of uncompressed audio. Users can back up the audio or use the microphone as a recorder during recording. It ensures audio integrality, making creation more secure. 5. Universal for Camera/ Smartphone/ PC: Both of the microphone and receiver support USB-C digital output and 3.5mm TRS/TRRSanalog output, which is widely compatible with cameras, smartphones, computers, etc. Specification: Polar Pattern: Super CardioidTransmitting Way: Wired/WirelessDual-channel: SupportFloating-point Recording: 32-bit FloatOn-board Storage: 32GB On-board StorageApp Operation: Comica Audio AppLow-cut: SupportHigh-frequency Boost: SupportSafety Track: SupportMonitoring: SupportDigital Output: USB-C 48kHz/24bitAnalog Output: 3.5mm TRRS/TRS Auto-sensingMuting: SupportGain Adjustment: SupportVisual Operation: SupportBattery Capacity: 3.7V 350mAh (transmitter), 3.7V 3300mAh (receiver)DurationTransmitter: Wired Mode 32H; Wireless Mode 10H; On-board Recording Mode 5H Receiver: 8HFrequency Range: 20Hz ~ 20kHzSensitivity Range: -38dB ~ -18dB re 1V/Pa(12mv ~ 125mv at 94dB SPL) +2dB at 1kHzS/N: 75dBOperating Temperature: 0?? to 50??Wireless Type: 2.4GDimensions: 22x224mm(transmitter), 54x48x22mm(receiver)Net Weight: 94g(transmitter), 29.5g(receiver) Package List: 2 * Microphones1 * Receiver1 * 2-in-1 Charging & Output Cable1 * 3-in-1 Charging Cable1 * 3.5mm TRS to TRS Audio Output Cable1 * 3.5mm TRRS to TRRS Audio Output Cable2 * Shock Mounts2 * 3/8 Male to 5/8 Female Stand Adapters2 * 5/8 Male to 3/8 Female Screws2 * 3/8 Male to 1/4 Female Screws2 * Windscreens2 * Wind-muffs1 * Pin1 * Carrying Case1 * Users Manual
