AKG SR45 High-Performance Wireless Stationary Receiver – Frequency U5
The SR45 is a compact, rack-friendly stationary receiver engineered for reliable wireless audio capture in studio and live recording environments. Its space diversity design and robust construction integrate seamlessly into fixed setups, delivering consistent RF reception without antenna repositioning or signal management headaches. Built for production rooms that demand simplicity and dependability—home studios, project spaces, live tracking sessions, and multi-room facilities—this receiver handles up to 6 simultaneous wireless channels with minimal fuss, freeing you to focus on capturing performances.
RF Performance & Recording Clarity
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 essential for multi-microphone sessions and ensemble recordings. The 105 dB(A) signal-to-noise ratio preserves transparent audio during tracking, while adjustable squelch control ensures clean, dropout-free transmission across varying RF environments and frequency congestion levels.
Connectivity & Studio Integration
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 mixing consoles, interfaces, and preamp chains. A front-panel audio clipping and RF signal LED provides real-time monitoring during tracking and overdubs, eliminating uncertainty during critical recording moments.
