AKG HT45 BD A Wireless Microphone System 45

AKG HT45 BD A Wireless Microphone System

The AKG HT45 BD A is a compact handheld wireless microphone system engineered for studio sessions, remote recording, and portable home-studio setups that demand reliable RF performance without excess weight. At 214 grams with an ergonomic 237mm profile, it remains unobtrusive during takes and overdubs, while the noiseless on/off/mute switch and integrated gain control streamline workflow between tracking passes. The cardioid dynamic capsule (P5 head) captures close-proximity vocals with natural presence and effective rejection of room reflections and ambient noise—critical for clean isolation in less-than-ideal recording spaces.

Wireless Performance & Studio Flexibility

Operating across the 500–865 MHz band with 8 selectable frequencies, this system navigates interference from WiFi, cell networks, and other RF sources common in home and professional studios. The 10 mW RF output delivers a 30-meter line-of-sight range, enabling freedom of movement within a typical tracking room or between isolated booths without tethering to a cable. FM modulation ensures clean, dropout-resistant signal transmission to its paired receiver, maintaining take continuity and reducing the need for re-records due to transmission artifacts.

Audio Quality & Recording Runtime

Signal-to-noise performance reaches 105 dB(A) with minimal distortion (0.8% THD at 1 kHz), preserving vocal detail across the full 70–20,000 Hz audio bandwidth for transparent captures that sit well in the mix and require minimal de-essing or corrective EQ in post. A single AA 1.5V battery powers the transmitter for up to 10 hours of continuous use, eliminating the need for external packs or proprietary power solutions and reducing changeover time during long session days.
