Description
AKG SR45 High-Performance Wireless Stationary Receiver – Frequency U5
The SR45 is a compact, rack-friendly stationary receiver built for gigging musicians and touring bands who need rock-solid wireless performance night after night. Its space diversity design and robust construction ensure consistent RF reception across any venue—no antenna tweaking between sets, no dropouts during your solo. Built for the rigors of live performance—clubs, theaters, festivals, and larger stages—this receiver handles multiple wireless instruments and vocals simultaneously, letting your band focus on playing instead of troubleshooting gear.
RF Performance & Audio Quality
Operating across the 530–560 MHz U5 frequency band with a 30 MHz selection bandwidth, the SR45 accommodates up to 6 simultaneous channels, making it ideal for multi-guitarist setups, dual vocalists, or full band wireless rigs. The 105 dB(A) signal-to-noise ratio delivers the clean, transparent audio tone you need on stage, while adjustable squelch control keeps your performance locked in tight across packed RF environments and venue frequency congestion.
Connectivity & Control
Audio outputs are available via both professional balanced XLR and unbalanced 1/4" (6.3 mm) jack connectors, each independently adjustable from mic to line level for seamless patching into your existing live mixing chain or pedalboard interface. A front-panel audio clipping and RF signal LED gives you real-time visual feedback during the gig, so you always know your wireless link is solid and your tone is clean.
