The Shure PA421A combines the RF signals of up to four Shure PSM in-ear monitor transmitters into one antenna and distributes DC power to them, improving RF performance and reducing rack clutter.
The PA421A is a wideband combiner covering 470 to 952 MHz, so it works across many PSM transmitter bands.
The PA421A only powers the amplifier for each active channel, while the older PA421SWB ran all amplifiers regardless of use. The PA421A also has a quieter, temperature-controlled fan.
The PA421A runs on 100 to 240 V AC at 50/60 Hz and draws up to 80 W, so it works on UAE mains power with the correct cable.
The PA421A measures 43 x 401 x 365 mm (1 rack unit high) and weighs 4.3 kg.
Trianze Tech stocks the Shure PA421A in Dubai with fast delivery across the UAE and GCC. Call +971 58 161 3661 or message us on WhatsApp for the best price and current stock availability.
