AKG WMS40 Mini Instrumental Set US45C - UHF 662.300 MHz Wireless System with Beltpack and Receiver

The AKG WMS40 Mini Instrumental Set US45C is a fixed-frequency 662.300 MHz UHF wireless system designed for instruments such as guitar or bass. It includes the compact SR40 Mini receiver, the PT40 Mini bodypack and the MKG L instrument cable (mini-XLR to 6.35 mm jack), offering a plug & play solution with up to 30 hours of battery life on a single AA battery. HDAP (High Definition Audio Performance) technology and analog FM modulation provide clear and stable sound , while the receiver integrates status LEDs (ON/OFF, RF OK and AF CLIP) and volume control on the output for immediate integration into any equipment.

The radio link operates with a typical power of 10 mW (ERP) and an audio bandwidth of 40 Hz to 20 kHz , with a 110 dB(A) signal-to-noise ratio and a typical THD of 0.8% . The SR40 Mini offers a 6.35 mm jack (TRS balanced) output and is powered by a universal 110–240 V AC switching power supply (EU/UK/US adapters included). The PT40 Mini incorporates a 3-pin mini-XLR connector, gain control and silent ON/OFF/MUTE switch. Its compact design facilitates mobility in stages, rehearsal rooms, theaters or corporate events.
