The AKG WMS420 UHF Wireless Instrumental System is designed for live sound reinforcement applications such as for public address, presentations, installations, and performances that require up to eight simultaneously operating systems over a 30 MHz bandwidth. This system consists of a PT420 Beltpack Wireless Microphone Transmitter, an SR420 UHF Stationary Wireless Receiver, two detachable RF antennas, an AC adapter for the receiver, a AA-size battery for the transmitter, and a 1/4" instrument cable.

The UHF receiver features two detachable antennas that enable connection to a wide range of professional RF accessories such as antenna splitters and remote mounted directional antennas for use with multi-channel systems. The front panel of the receiver features an on/off button, a rotary volume control, a button for selecting one of the available eight carrier frequencies within the system's range, an LCD display that shows the selected receiving channel, an RF OK LED to indicate the presence of a signal, and a CLIP LED to indicate when the audio level is too high.

The back panel of the receiver features a squelch control knob that will automatically mute the audio output if the strength of the radio transmission frequency becomes too weak. The back panel also features a DC IN port with strain relief for connecting the AC adapter, a balanced XLR-3F output for connecting to a live mixer, and an unbalanced 1/4" output for connecting to a guitar or instrument amplifier.

The beltpack wireless transmitter comes with a 1/4" instrument cable, but will also work with any of AKG's line of MicroMics. The beltpack features a noiseless on/off/mute switch, a gain control knob, and an LED indicator light. The transmitter is powered by a single AA battery which provides between six and eight hours of operating time with a range of approximately 30 meters. The transmitter also includes charging contacts for use with rechargeable batteries and AKG's CU400 rechargeable base station (sold separately).

Smooth and quiet wipe
Size: Combo Pack (26" & 20"), Style: Top Lock Narrow, Size: Combo Pack (26" & 20"), Style: Top Lock Narrow
Swapped these onto my car and they work great. Installation was quick and easy, took just a couple minutes. The wipe is smooth and quiet with no streaks, even in heavier rain. Feels like a solid upgrade compared to cheaper blades I’ve used before. So far very satisfied.

Terrific Bosch blades
Size: Combo Pack (26" & 20"), Style: Top Lock Narrow, Size: Combo Pack (26" & 20"), Style: Top Lock Narrow
These German made wiper blades do their job so well that my wife was impressed. Once you get the hang of it they are one minute to replace. Recommend placing a cloth under the blade to avoid any windshield scratches if the metal wiper assembly accidentally falls down on the glass. Nice to see the Bosch name on the wiper blades.

Best replacement option for 2025 Tesla Model Y Performance
Size: Combo Pack (26" & 20"), Style: Top Lock Narrow, Size: Combo Pack (26" & 20"), Style: Top Lock Narrow
Outstanding replacement option for 2025 Tesla Model Y Performance (Pre-Juniper), so much smoother than the OEM wipers. Very easy to replace. They seem very durable after testing on all wiper settings. Definitely keep the windshield clearer without streaks. Seem to also have more stability on mounting compared to OEM option. 15/10 replacement for the cost, can’t beat it.
