1、P E R F O R M A N C E I S E V E R Y T H I N G OM3xbDYNAMIC VOCAL MICROPHONE overview The OM3xb, first introduced in 1989, is the original VLM Technology high output vocal microphone. An American-made, hand held vocal microphone designed for live perform- ance, the OM3xb is characterized with a hyper

2、cardioid pickup pattern and a uniform frequency response of 50-18kHz. An excel- lent choice for any size stage, the OM3-xb can provide over 25 dB of feedback rejec- tion off-axis and is able to handle extreme- ly high levels of gain without distortion. Transformerless design, low impedance, and bala

3、nced output allow interference-free per- formance even with long cable runs. The OM3xb produces a highly accurate, natural sound with slight bass proximity. A dent- resistant spring-steel grill and sound pres- sure handling capabilities in excess of 144dB add to the OM3xbs road-worthiness. The OM3xb

Operation and Maintenance: The OM3xb is a durable handheld dynamic microphone with a dent-resistant spring steel grill. It still should be handled with care. Avoid extreme te

9、mperatures wherever possible. Warning: Avoid moisture as it can adversely affect the sound and performance of your micro- phone. Phantom power: The OM-3xb is a dynamic micro- phone and does not require phantom power, be assured that Phantom power will not adversely affect the performance of the OM-3

10、xb in any way. Recording: The OM3xb is a very versatile recording microphone. It is a cost-effective utility microphone for use with vocals, percussion, electric and acoustic guitar, and brass instruments, providing a full-bodied warmth that complements lower-profile floor monitors found in smaller

11、performance venues. Because of the hypercardioid pattern, it is less susceptible to feedback than comparably priced cardioid designs. Its high sound pressure handling will prevent diaphragm distortion, allowing for close miking of the instrument or voice. Live Sound: The OM3xbs tight pattern and hig

12、h off-axis rejection offer unmatched gain before feedback at an affordable price. The high rejection also allows multiple miking in tight quarters (i.e. small clubs) with little bleed through or feedback. The OM3xb has added warmth in the lower mid-bass and a slight boost in the mid-range; it sounds

13、 particularly full and clear on small-to-mid size PA systems without having to add EQ or pad the sensitivity. Microphone placement is not an exact science and depends on the room size, the PA system, and the musicians. Therefore, some experimentation is usually necessary in order to achieve the desi
