Crown Audio CM-30 CS Series Condenser Microphone Crown Audio CM-311A Differoid Head-Worn Condenser Microphone
The CM Series of condenser microphones by Crown offer exceptional quality at truly affordable prices. With application-specific microphones, ranging from professional-grade headworn microphones to critical-response microphones for the most demanding recording applications, the CM Series can fit most any microphone need. Types include hand-held, headworn, hanging, or stand-mounted.

With innovations such as Crown's patented Differoid technology, the CM series combines years of technical know-how with durable, high-quality materials and workmanship. These qualities are direct contributors to the successful performances of our customers, and a primary reason for the success Crown enjoys today.

The Crown® CM-30 is a professionalquality, supercardioid condenser microphone designed for inconspicuous miking of a choir, orchestra or stage. The mic cable connects to the electronics/faceplate which fits a standard electrical outlet box.

The CM-30 can also hang over conference tables or discussion groups for inconspicuous isolated miking. Because of its supercardioid pickup pattern, the CM-30 rejects background noise and room reverberation, and improves gain-before-feedback more than a cardioid microphone.

The CM-30 has a smooth, wide-range frequency response for natural reproduction of the singing voice, organ or other musical instruments. Extreme low frequencies are filtered out to reduce pickup of room rumble. The microphone output is balanced, low impedance. It is protected against static and radio frequency interference. A built-in removable hanger allows easy position adjustment by bending the lower portion of the hanger.

The CM-30 requires 12-48V phantom power. The CM-30 is black; the CM-30W is white.

  • Designed for touring and live-sound applications, the Crown® CM-311A is a rugged head-worn microphone with unequalled performance. It sounds like the best handheld microphones—full, clear, and distortion-free, even with the loudest singers.

    The CM-311A is the latest version of the Crown’s proprietary Differoid® technology. Its cardioid pickup pattern rejects sounds from the rear, such as floor monitors. Its noise-canceling ability rejects sounds at a distance, such as instruments on stage and crowd noise. This results in the CM-311A having outstanding gain-before-feedback and isolation.

    Lightweight and comfortable, the mic’s headband and boom adjust to fit any singer. An included pop filter greatly reduces breath noise and pops. Because of the boom’s unique behind-the-ear design, it does not cover up the singer’s face. Two models are available: CM-311A and CM-311AE. The CM-311A is powered by a 9V battery or phantom power. It has a battery belt pack with an on/off switch, a programmable mic on/off switch, and a “Mic On” LED. The CM-311AE is a pig-tail version allowing you to connect it to most wireless transmitters.

    Note: Putting an XLR connector on the CM-311AE and connecting to a mic input with phantom power WILL damage the mic element. For wired applications, use the CM-311A. How to adjust for best fit and to prevent boom bounce
    Note: To get the maximum performance out of this microphone, take the time to adjust it to fit correctly. For best results, the CM-311A MUST be custom fitted to a single user’s head.

  • Crown Audio LM-201 Supercardioid Lectern Microphone Crown Audio LM-300A Supercardioid Condenser Dual Gooseneck Lectern Microphone
    The Crown® LM-201 is a professional quality, supercardioid electret condenser microphone designed for use on lecterns, pulpits, or similar applications. The microphone is easily installed with the included mounting screws. As it is swiveled to the desired position, adjustment is far quieter than conventional gooseneck microphones. Swivel motion is limited to prevent cable damage.

    The LM-201 is rugged and is built to withstand daily use. Because of its supercardioid pickup pattern, the LM-201 rejects background noise and room reverberation, improving gain-before-feedback more than a microphone with a cardioid pattern. The LM-201 has a smooth, wide-range frequency response for natural reproduction of the voice. Low frequencies are filtered out to reduce pickup of lectern thumps, room rumble, etc.

    The included wire-screen grille has a two-stage pop filter to reduce pickup of explosive breath sounds. An external foam windscreen is supplied for extra pop rejection or for outdoor use. The base and mic capsule are shock-mounted to attenuate handling noise and lectern thumps. The microphone output is balanced, low impedance, which allows long cable runs without hum pickup or high-frequency loss. Two finishes are available: black (model LM-201P) or brown (model LM-201B).

  • The Crown LM-300A is a dual-gooseneck microphone for lecterns, pulpits, or similar applications. The mic is identical except for arm length (see Figs. 3 and 4). Each professional-quality mic is an electret-condenser type with a supercardioid pickup pattern. The mic plugs directly into a female 3-pin XLR-type panel connector.

    Because of its supercardioid pickup pattern, the LM-300A rejects more background noise, room reverberation, and feedback than a typical cardioid microphone. The model has a smooth, wide-range frequency response for natural reproduction of the singing or speaking voice. Very low frequencies are filtered out to reduce pickup of mechanically induced noise, room rumble, etc. The goosenecks adjust silently.

    Supplied with the microphone is the WS-9, a highly effective foam pop filter. Its two-stagedesign greatly reduces explosive breath sounds. A low-cut switch built into the electronics housing further reduces breath pops and handling noise. Optional accessories include the LM-SM lockable shock mount, which provides mechanical isolation when mounted in a pulpit, lectern, or table top.

    The microphone connector is a male 3-pin XLR-type for easy plug-in installation. The output is balanced and low impedance which allows long cable runs without hum pickup or high frequency loss. Superior RFI protection is also provided. Requires 12-48 V phantom power.

  • The Crown® PCC-130SW is a surfacemounted supercardioid microphone of professional quality. This handsomely styled unit is appropriate for use on the most elegant boardroom table or lectern. Other applications include distance learning, teleconferencing, courtrooms and council chambers.

    The PCC-130SW has a silent-operating membrane switch which is normally off. The switch can be confi gured for touch on/off, momentary on or momentary off. This configuration is set by a bottom-mounted slide switch. A high-intensity LED lights when the unit is on. The PCC- 130SW is intended for multiple-microphone useon a conference table where each person wants control of his or her microphone. A ¼-inch (6.35-mm) stereo phone-plug option is available as the PCC-130SW/ SPP.

    The microphone attenuates 70 dB when the switch is in the off position. Since the microphone capsule is placed on a boundary or surface, direct and refl ected sounds arrive at the diaphragm in-phase resulting in a wide, smooth frequency response free of phase interference. Clarity and reach are also enhanced. Self-contained electronics eliminate the need for an in-line preamp.

    Powered by 12-48V phantom power, the PCC-130SW has a low-impedance balanced output which permits long cable runs without hum pickup or high-frequency loss. A 15-foot (4.6-m), two-conductor-shield microphone cable is included with a TA3F connector (mic end) and 3-pin male XLR-type connector (output).

    Although the standard connector on the microphone is a Switchcraft TB3M, the microphone can be special-ordered with a ¼-inch (6.35-mm) stereo phone plug on the bottom of the base plate as the PCC-130SW/ SPP. RFI suppression is included. Self-noise is low and sensitivity is very high. A bass-tilt switch allows the user to tailor the low-end response for particular applications.

    Membrane Switch
    The PCC-130SW membrane switch can be configured to work three ways:
    1. Touch on/off. Touch the switch to turn on the mic; touch it again to turn off the mic.
    2. Momentary on. Touch and hold the switch to turn on the mic momentarily. Release the switch to turn the mic back off.
    3. Momentary off. Touch and hold the switch to turn off the mic momentarily. Release the switch to turn the mic back on. This option serves as a cough button or privacy button.

    After choosing the option you prefer, set the slide switch according to the label on the bottom of the microphone. The LED in the microphone housing will light when the mic is on.

  • Crown Audio PCC-160 Phase Coherent Cardioid Microphone Crown Audio PCC-160W Phase Coherent Cardioid Microphone, White
    The Crown® PCC®-160 (Phase Coherent Cardioid®) is a surface-mounted halfsupercardioid microphone intended for professional applications on stage floors, lecterns, conference tables, and news desks—wherever improved gain-before-feedback and articulation are important.

    Similar to the Pressure Zone Microphone® (PZM®), the PCC is designed to be used on a relatively large boundary surface. Unlike the PZM, the Phase Coherent Cardioid uses a subminiature supercardioid mic capsule. Its directional polar pattern improves gain-before-feedback, reduces unwanted room noise and rejects sounds from the rear.

    Surface-mounting creates a “half-supercardioid” polar pattern and increases directivity 3 dB. Since the microphone capsule is placed on a boundary, direct and reflected sounds arrive at the diaphragm in-phase. This coherent addition of direct and reflected waves increases sensitivity 6 dB and prevents phase cancellations. The mic capsule is small enough to ensure phase coherency up to the highest frequencies in the audible spectrum, resulting in a wide, smooth frequency response free of phase interference. Clarity and reach are also enhanced.

    Self-contained electronics eliminate the need for an in-line preamp box. The PCC-160 can be phantom powered directly from the console or other remote power source providing 12 to 48 volts. If battery power is required, a battery supply unit can be inserted anywhere in the mic line right up to the console or mixer. A “bass tilt” switch allows the user to tailor the low-end response for particular applications.

    Thanks to its low profile and black finish, the microphone becomes almost invisible in use. A side-mounted connector complements the form factor of the PCC-160, allowing the unit to be placed effectively at the stage edge, at the top of a lectern or in other tight spots. If desired, the cable can be hard-wired for bottom entry.

    The PCC-160W is finished in off-white to blend with surroundings where lighter color is appropriate. The heavy-gauge, all steel body protects the unit from accidental abuse. Permanent mounting is enabled by screw holes in the base. Engineering attention-to-detail has assured years of trouble-free use from this reliable microphone.

    Capable of withstanding up to 120 dB SPL without distorting, the PCC-160 will never overload in practical use. Its electret condenser capsule provides a wide, smooth frequency response from 50 Hz to 18 kHz. RFI suppression is included. Self-noise is low, and sensitivity is very high to override mixer noise in distant-miking applications. Output impedance is 150 ohms, balanced. Half-supercardioid polar pattern rejects pit orchestra and offers high gain-before feedback.

  • Crown Audio PCC-170SW Phase Coherent Cardioid Microphone, Switch Version, Polar Pattern Crown Audio PCC-170W Phase Coherent Cardioid Microphone, Low Impedance, White
    The Crown® PCC®-170SW is a surface-mounted supercardioid microphone of professional quality. This handsomely styled unit is appropriate for use on the most elegant boardroom table or lectern. Other applications include churches, courtrooms and council chambers.

    The PCC-170SW has a silent-operating membrane switch which is normally off. The switch can be configured for touch on/off, momentary on or momentary off operation. This confi guration is set by a bottom-mounted DIP switch. A high-intensity LED lights when the unit is on.

    The PCC-170SW is intended for multiplemicrophone use on a conference table where each person wants control of his or her microphone. The microphone attenuates 70 dB when the switch is in the off position. Since the microphone capsule is placed on a boundary or surface, direct and reflected sounds arrive at the diaphragm in-phase, resulting in a wide, smooth frequency response free of phase interference. Clarity and reach are also enhanced.

    Self-contained electronics eliminate the need for an in-line preamp. Powered by 12-48V phantom power, the PCC-170SW has a low-impedance balanced output which permits long cable runs without hum pickup or high-frequency loss. Although the standard connector option is a Switchcraft TB3M, the microphone can be special- ordered with a ¼-inch (6.35-mm) stereo phone plug on the bottom of the base plate as the PCC-170SWSPP.

    RFI suppression is included. Self-noise is low and sensitivity is very high. A bass-tilt switch allows the user to tailor the low-end response for particular applications.

    Membrane Switch
    The PCC-170SW membrane switch can be confi gured to work three ways:
    1. Touch on/off. Touch the switch to turn on the mic; touch it again to turn off the mic.
    2. Momentary on. Touch and hold the switch to turn on the mic momentarily. Release the switch to turn the mic back off.
    3. Momentary off. Touch and hold the switch to turn off the mic momentarily. Release the switch to turn the mic back on. This option can serve as a cough or privacy button.

  • The Crown® PCC-170 is a surfacemounted supercardioid microphone of professional quality. This handsomely styled unit is appropriate for use on the most elegant boardroom table or lectern. Other applications include courtrooms and council chambers. Because of its highly directional pickup pattern, the PCC-170 minimizes background noise and feedback.

    The microphone reproduces the voice with a clean, clear and natural sound. Since the microphone capsule is placed on a boundary or surface, direct and reflected sounds arrive at the diaphragm in-phase. This coherent addition of direct and reflected waves increases sensitivity 6 dB and prevents phase cancellations. The mic capsule is small enough to ensure phase coherency up to the highest frequencies in the audible spectrum, resulting in a wide, smooth frequency response free of phase interference. Clarity and reach are also enhanced.

    Self-contained electronics eliminate the need for an in-line preamp. Powered by 12-48V phantom power, the PCC-170 has a low-impedance miclevel balanced output which permits long cable runs without hum pickup or high-frequency loss. Although the standard connector option is a Switchcraft TB3M, the microphone can be specialordered with a 0.25-in. (0.635-cm) stereo phone plug on the bottom of the base plate as the PCC-170SPP.

    The PCC-170W is finished in off-white to blend with surroundings where the lighter color is appropriate. RFI suppression is included. Self-noise is low and sensitivity is very high. A bass-tilt switch allows the user to tailor the low-end response for particular applications.
