AKG PT45BDD - PT45 Band D Wireless Bodypack

AKG PT45 BDD – Band D (863.1–864.9 MHz) Wireless Beltpack for Perception Wireless 45 Systems

The AKG PT45 Band D is an analog UHF bodypack from the Perception Wireless 45 Series designed for vocal and instrument applications in installations, education, worship, and events. It operates in Band D (European channel 70, 863.1–864.9 MHz) , a generally unlicensed band of use in much of Europe (subject to local regulations). It features a 3-pin mini XLR connector for compatibility with the AKG MicroMics range and the MKG L instrument cable, a gain control for adjusting the input level, and a silent On/Mute/Off switch that prevents popping when unmuted. The battery indicator turns red with approximately one hour of battery life, ensuring predictable live use.

Within its band, the PT45 offers selectable fixed frequencies (up to 8 depending on band/country) with switching up to 30 MHz in the PW45 family. It delivers 40 Hz–20 kHz audio with a typical SNR of 105 dB(A) and THD of 0.8% , operates on a single AA battery and achieves up to 10 hours of battery life . Its electronics provide ~4 V power for AKG condenser microphones and a nominal RF power of 6 mW , sufficient for stable links with the SR45 receiver in stages and medium-sized rooms.
