Acefast R7 Wireless Microphone

Acefast R7 Wireless Microphone

The Acefast R7 Wireless Microphone sets a new benchmark for accessible, professional-grade audio capture in the Bangladeshi audio-visual market. Designed specifically as an adaptable wireless lavalier microphone to overcome common mobile recording challenges—such as room echo, traffic noise, and heavy equipment—the Acefast R7 Wireless Microphone delivers crystal-clear 48kHz/16-bit HD sound directly to your USB Type-C smartphone, tablet, or laptop. Whether you are broadcasting live on Facebook, recording TikTok clips, or filming outdoor vlogs, this wireless lavalier microphone provides an effortless plug-and-play experience without requiring external apps or complex software setup.

Electret Capsule Engineering & 360° Omnidirectional Pickup

At the core of the Acefast R7 Wireless Microphone is a permanently polarized electret microphone capsule featuring -42dB acoustic sensitivity. Built as an omnidirectional wireless lavalier microphone, its 360-degree pickup pattern ensures consistent vocal warmth and balanced audio capture even when the presenter moves off-axis or turns away from the camera lens. Captured sound is converted through an onboard Analog-to-Digital Converter (ADC) at a 48kHz / 16-bit studio sampling rate, preserving human speech harmonics across an ultra-wide frequency bandwidth.

Dual-Mode DSP: AI Noise Reduction vs. Hi-Fi Mode

The Acefast R7 Wireless Microphone incorporates advanced dual-mode Digital Signal Processing (DSP) accessible right from the transmitter interface:

• AI Active Noise Reduction Mode: Intelligently analyzes incoming acoustic signals to suppress environmental background noise, including ceiling fan hums, air conditioner drone, traffic rumble, and street noise common in Bangladeshi urban settings.
• Hi-Fi Ambient Mode: Bypasses aggressive noise filtering in this wireless lavalier microphone to preserve natural room resonance and full vocal timbre, making it ideal for acoustically treated studios, quiet indoor spaces, and musical performances.

Reliable 2.4GHz Transmission & Ultra-Low Latency

Operating on the license-free 2.4GHz ISM radio band (2400 MHz to 2483.5 MHz), the Acefast R7 Wireless Microphone utilizes an internal ceramic antenna to maintain signal stability across an unobstructed line-of-sight range up to 50 meters. With an ultra-low latency profile of approximately 25 milliseconds (~25ms), this wireless lavalier microphone ensures exact lip-sync alignment for live streams, online classes, and video interviews.

Continuous Pass-Through Charging & Battery Life

The 4-gram receiver unit plugs into your host device's USB-C port and features an integrated pass-through USB Type-C charging port. This pass-through charging design lets creators plug in a power bank or wall charger to power their smartphone simultaneously while recording with the Acefast R7 Wireless Microphone during multi-hour Facebook Live or TikTok sessions. The transmitter's 50mAh lithium-ion battery offers up to 5 continuous hours of operation. When low on power, a quick 10-minute fast charge via USB-C yields approximately 1 hour of active runtime, with full recharging completed in 1.5 hours.

User-Friendly Touch Control & IPX4 Protection

Managing live audio with the Acefast R7 Wireless Microphone is intuitive. A double-tap gesture on the transmitter's capacitive touch surface instantly mutes this wireless lavalier microphone at the hardware level, allowing presenters to manage off-camera comments without interrupting the broadcast. Multi-color LED indicator lights clearly signal active pairing, mute status, low battery, and DSP modes. Furthermore, the durable ABS plastic body boasts an IPX4 splash resistance rating to guard against sweat and outdoor rain splashes.
