AKG WMS40M2MIXSTBDUS25AC - Instrumental Band US25A/C UHF Wireless System with 1 Beltpack, 1 Microphone and Receiver

AKG WMS40M2MIXSTBDUS25AC - US25A/C Dual UHF Wireless System with PT40 Mini Bodypack, HT40 Mini Microphone, and SR40 Mini2 Receiver

The AKG WMS40M2MIXSTBDUS25AC (also known as the WMS40 Mini2 Mix Set ) is a ready-to-use dual UHF wireless system combining an instrument channel via a PT40 Mini bodypack and a vocal channel via an HT40 Mini cardioid dynamic handheld microphone. It operates on two fixed frequencies in the US25A/C band: 537.500 MHz (US25A) and 539.300 MHz (US25C), allowing two channels to be used simultaneously without scanning. The SR40 Mini2 receiver integrates two independent receivers with balanced outputs per channel (6.35 mm TRS jack) , volume control and indicators per channel ( ON , RF OK , AF CLIP ). HDAP companding technology delivers clear sound with 40 Hz–20 kHz response, typical THD 0.8 % and typical SNR 105 dB(A) . Each transmitter lasts up to 30 hours on a single AA battery, making it ideal for rehearsals, live performance, worship, education, and rentals.
