Crown microphones effectively. The CM, GLM, and LM microphone lines are covered in this booklet. For application notes on the PZM®, PCC® and SASS®, please see the Crown Boundary Mic Application Guide. You will find that Crown microphones can solve many of your audio problems. -
Page 4: Reduce Background Noise And Leakage
• Use a Differioid mic on vocals such as the Crown CM-310A or CM-311A. How to pick up sound at a distance The farther you place a microphone from a sound source, the more reverberation, leakage, and back- ground noise you pick up. Also, you hear more mixer noise compared to the signal because the mixer gain must be higher with distant miking. -
Page 5: Reduce Phase Cancellations Between Two Mics
CM-310A. • Place an external foam pop filter on the microphone. • Place the microphone out of the path of pop travel - above, below, or to the side of the mouth. • Roll off low frequencies below 100 Hz. -
Page 6: Achieve A Natural Tone Quality
How to achieve a bright tone quality A “bright” sound is crisp, clear, trebly, and articulate. To achieve a bright sound, use a microphone with a rising high-frequency response, such as a Crown GLM-200 or a PZM-30D / PZM-6D set to “rising”... -
Page 7: Cm-150
Designed for installation by sound contractors, this model has a separate circuit module. The microphone is shock mounted, and is meant to be permanently screwed to the lectern top. The LM-300A is a gooseneck microphone that plugs into an XLR-type connector mounted in your lectern. -

An excellent choice for this is the Crown CM-311A. It is worn with lips touching the microphone, and offers extremely high gain- before-feedback and isolation. For less critical situations, use a CM-312A. It is smaller and lighter than the CM-311A, and the mic is at the side of the mouth. - Page 9 • Tape the cable of a GLM-100 to the grille cloth in front of a speaker cone. A mic placement at the center of the cone sounds bright; a placement near the edge of the cone sounds more mellow. Drum set (Figure 7): Toms and Snare, Recording/Reinforcement: •...
- Page 10 Percussion Recording/Reinforcement: • Place a CM-700 about 1 foot away. • Tape a PZM on the musician’s shirt (see the Crown Boundary Mic Application Guide). Ambience Recording: • Place one or two PZMs on a distant wall, or on the control-room window.
- Page 11 • For maximum isolation and gain-before-feedback, use a GLM-100 close to the drum head a few inches in from the rim. • Place a CM-700 12 inches from the drum head for recording, closer for sound reinforcement. Violin Recording: • Place a CM-700 or CM-150 1 to 2 feet away over the top.
- Page 12 5 to 15 feet in front of the front-row musicians. • See the Crown Boundary Mic Application Guide for more suggestions. The SASS is especially useful for this application. Reinforcement: • For sound reinforcement of an orchestra or band, mike each section separately a few feet away with a GLM-100, CM-30, or CM-31.

Page 14: Choosing The Right Crown Microphone
This guide will help you select the microphones best-suited for your applications. Transducer Type Condenser or Dynamic In a dynamic microphone, a coil of wire attached to a diaphragm is suspended in a magnetic field and generates an electrical signal similar to the incoming sound wave.
