Review by Stacy Zemon
Featuring clear, crisp vocal performance in a lightweight package, this microphone signifies the quality and performance value of the Crown CM Series of microphones.
One of the benefits of this headset design is it allows DJs to get on the dance floor and interact with the crowd.
The Crown CM-311A is a cardioid pattern which uses Crown’s Differoid® technology to reject sounds from the rear of the microphone. This innovation allows crowd noise to be rejected for a high gain before feedback.
With a headset weight of only 2.1 oz, one can barley notice it is being worn. The headset is hard wired into a belt pack to prevent a mic jack from popping loose or connection related problems The belt pack with battery installed has a insignificant weight of only 6.1 oz.
Accessible on the top of the belt pack is a programmable mic on/off switch. This switch can be set up to work in three different ways, push on or push off, momentary on, or as it is supplied from Crown, momentary off. Removing three screws to the belt pack case allows access to a miniature switch to change the switch settings.
The flexibility of these switches would allow an MC to turn the mic off completely or just press and hold the button in the instance of coughing or clearing ones throat.
Next to the switch is a small red LED, which lights after the unit power switch has been turned on. A large metal belt-clip is permanently attached to the belt pack for hands free use. For ease of hook up, a male XLR connector is recessed within the bottom of the high-impact plastic belt pack.
The headset headband is made of bendable steel wire. The mic boom is constructed from durable non-flexible brass tubing. The 2-conductor shielded cable is 42 inches in length from headset to belt pack. A small clip is fastened to the cable for attaching to one’s clothing.
The microphone element is housed within a small rounded silver grill, which is attached to the fully adjustable brass mic boom. A large user friendly knob or thumbscrew allows for complete adjustment of the boom, in or out and down or up. Attached to the underside of this knob is a large padded foam block. This block sits just below the right ear and becomes the stabilizer for the mic boom and element.
To prevent the mic boom from bouncing, Crown suggests bending the headband wire, both side ear pieces and the wire assembly which holds the padded block for the best fit possible. Included with the mic is a foam pop filter which snaps down over the metal windscreen. The transducer on the head set is called an electret condenser.
The element reproduces frequencies from 50 Hz to 17 kHz and has a cardioid pattern. This element can take up to a maximum SPL of 148 dB with only 3% THD according to Crown’s manual. The manual also states, up to 110 hours of battery usage can be achieved.
