AKG Instrument Set Overview

  • 1Description
  • 28 Fixed Frequencies Available for UHF Wireless Channels
  • 3Detachable Antennas
  • 4Squelch Control
  • 5Rechargeable Contacts on Transmitter

The WMS420 Wireless Instrument System from AKG offers guitar, bass, and keyboard players a simple-to-use wireless system for live sound applications including performances, presentations, and installations. This system consists of a PT420 bodypack transmitter with a 1/4" instrument cable and a SR420 tabletop UHF receiver.

The system uses dual-antenna diversity to improve signal reliability and reduce dropouts and offers a maximum range of 100'. For improved reception with multichannel setups, the included 1/4-wave antennas can be removed and upgraded with professional RF accessories such as antenna splitters and remote-mounted directional antennas.

The beltpack transmitter includes a 1/4" guitar cable, but will also work with a wide variety of AKG lavalier and headset microphones with a TA3F connector. The beltpack features a noiseless On/Off/Mute switch, a gain control knob, an LCD channel display, and a battery status LED indicator.

The transmitter is powered by a single AA battery (included) which provides up to six hours of operating time—and even up to 8 hours depending on battery type and use circumstances. The transmitter also includes charging contacts for use with rechargeable batteries and AKG's CU400 rechargeable base station (both available separately).

The front panel of the receiver features an On/Off button, a rotary output volume control, and a button for selecting one of the available eight carrier frequencies within the system's range. An LCD display shows the selected receiving channel, an RF 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 an adjustable squelch control that will automatically mute the audio output if the strength of the radio transmission becomes too weak. A DC IN port with strain relief accommodates the included AC adapter. The balanced XLR output lets you connect to a mixer, while the unbalanced 1/4" output is ideal for connecting to a guitar amplifier.

8 Fixed Frequencies Available for UHF Wireless Channels

The WMS420 offers 8 preset frequencies in the UHF spectrum, which can be deployed to create a clear wireless operating channel with a range of up 100'. If interference should occur, simply switch to another frequency and resync the components. A total of 8 systems can be used at one time.

Detachable Antennas

The included antennas can be removed to enable the use of professional RF accessories such as antenna splitters and remote antennas for multi-channel systems.

Squelch Control

Squelch automatically mutes the audio output if the signal strength of the transmission frequency falls below an adjustable threshold.

Rechargeable Contacts on Transmitter

Outside contacts on the bodypack transmitter allow you to recharge the battery while still inside the transmitter (rechargeable battery and charger available separately).
