Product Description

The QLXD2 handheld transmitter pairs with QLX-D digital wireless receivers to deliver transparent 24-bit digital audio with AES-256 encryption and reliable RF performance. Its KSM9 capsule uses a dual gold-layered, low-mass Mylar diaphragm with switchable supercardioid and cardioid polar patterns, giving sound engineers control over pickup and more gain before feedback in difficult rooms. The capsule's exceptional frequency consistency and reduced proximity effect make it well suited to demanding vocal applications in houses of worship, auditoriums, and broadcast studios. As part of the QLX-D platform, the transmitter benefits from one-touch sync with compatible receivers and efficient spectrum use for multi-channel deployments. This unit is supplied in the G50 frequency band.

Frequently Asked Questions

What receiver does this transmitter need? The QLXD2/KSM9 operates within the QLX-D system and pairs with a compatible receiver such as the QLXD4 digital wireless receiver.

When should I use supercardioid versus cardioid? Supercardioid offers tighter pickup and more rejection of off-axis sound for loud stages, while cardioid provides a slightly wider pattern for general use; the KSM9 lets you switch between them.

Is the audio secure for broadcast use? Yes. The QLX-D platform applies AES-256 encryption to protect the wireless signal.

Do you offer a bodypack option in the same family? For lavalier and headset applications, the ULXD1 bodypack transmitter is a comparable Shure digital wireless option.

What warranty and support apply? The transmitter carries Shure's standard manufacturer warranty; contact Creation Networks for warranty terms and AV integration support.
