Thank you for choosing Senal.
The Senal OLM-2 is a high-performance professional lavalier microphone. Its miniature, lightweight
design allows for discrete placement without compromising sound quality. This versatile workhorse
microphone is ideal for broadcast, video, and stage applications. Utilizing a broadcast-quality wide-
range electret condenser element, it features smooth frequency response and wide dynamic range.
Its omnidirectional polar pattern enables 360° sound pickup, capturing a natural blend of voice and
ambience with low sensitivity to wind and handling noise, as well as to vocal plosives. Designed to
connect to a wireless body pack, the OLM-2 can be combined with the Senal PS-48B Power Supply to
operate on phantom or battery power, enabling it to plug into any XLR microphone input.
