GENERAL

Contoured to fit comfortably in the palm of your hand, the Model 520DX ªGreen Bulletº microphone produces the unique sound that has made it a legend among harmonica players.

The 520DX features a volume control knob at the base of the microphone (see Figure 1) that allows musicians to make adjustments to suit their needs during a live perfor- mance. An attached cable with a standard 1/4-inch phone plug allows the microphone to be connected to a high-imped- ance device.

APPLICATIONS

Connect the 520DX directly into a guitar amplifier to produce the classic blues harp sound. Use the following guidelines:

￿The volume control on the microphone should be turned down before plugging it into an amplifier. As you move away from the amplifier, the volume can be turned up.

￿Adjust the microphone's volume control knob during performances as needed. For example, when switching from playing rhythm to lead or to place the microphone on standby between sets.

￿To avoid feedback, maintain as much distance as pos- sible from monitors or loudspeakers. Adjust the volume of monitors or loudspeakers at the mixing console so that no feedback is present when the volume control knob on the harmonica microphone is at its maximum setting.

NOTE: The volume setting of the guitar amplifier may have a significant effect on the overall tone produced. Experiment with different microphone and amplifier volume settings to achieve the desired effect.

This microphone is part of Shure's line of portable microphones and boasts several distinctive features and technologies that set it apart in the audio industry.

One of the main characteristics of the Shure 520DX is its classic design, which pays homage to the iconic green bullet microphone used in blues music since the mid-20th century. The microphone's unique shape not only adds to its aesthetic appeal but also influences its acoustic properties. The design includes an integrated stand mount and a die-cast casing that enhances its strength and ruggedness, making it a reliable choice for both studio recordings and live performances.

The frequency response of the Shure 520DX ranges from 50 Hz to 15 kHz, providing a warm and full-bodied sound profile. This microphone excels in capturing the nuances of vocal and instrumental performances, and the dynamic element allows for high sound pressure levels, making it ideal for loud sources. Its frequency response curve is tailored to emphasize mid-range frequencies, which are crucial for reproducing the timbre of harmonicas and the clarity of vocals.

Another significant feature of the Shure 520DX is its built-in compression technology, which helps to reduce distortion and improve the overall sound quality when dealing with louder audio sources. This technology ensures that users can achieve a smooth sound without clipping or unwanted artifacts, further contributing to its popularity in live settings.

The microphone also includes a classic windscreen that minimizes plosive sounds, ensuring clear articulation of vocals and instruments. Additionally, it employs a unidirectional cardioid pickup pattern, which helps to isolate the sound source while reducing background noise, making it especially useful in crowded environments.
