Frequently asked questions
Can I use the PT420 as a handheld vocal microphone like the WMS40?
No. The PT420 is a bodypack transmitter with a three-pin mini XLR input jack designed for instruments and headset mics. The WMS40 includes a cardioid dynamic handheld capsule built specifically for vocals and is ready to use as a complete system.
How long will each system run on batteries before needing replacement or recharge?
The WMS40 Mini runs 30 hours on a single AA battery in the handheld transmitter. The PT420 bodypack runs 8 hours on a single AA battery and includes a red battery-status warning light.
Do I need to own other equipment to use each system?
The WMS40 includes a receiver and can connect directly to a PA or amplifier via 1/4-inch jack—you only need a power outlet. The PT420 is a transmitter only and requires a separate AKG U2-band receiver to function.
Which system works better in crowded venues with many wireless devices?
The WMS40 operates on Band A (537.500 MHz) and requires no frequency coordination for most venues. The PT420 uses the U2 band (614.100–629.900 MHz) and may require frequency coordination in environments with multiple wireless systems, but both are professional-grade solutions.
