Earthworks SR40 Multi-Purpose Hypercardioid Condenser Microphone, 20Hz-40kHz Frequency Response, 65 Ohms Output Impedance, Matched Pair

The Earthworks SR40 is a directional pre-polarized condenser microphone (Matched Pair) with a first-order Hypercardioid pickup pattern directly coupled to a dedicated wideband, low output impedance transformer less preamplifier. The SR40 requires a standard 48V Phantom Power sup-ply. It features a flat frequency response from 20Hz to 40kHz, fast impulse response, very low handling noise, uniform polar pattern and high SPL handling capabilities. It provides excellent uncolored rejection of sounds arriving off-axis. The SR40 is protected by U.S Patent No. 6,091,829.

Applications
Earthworks SR40 is easy to operate. Connect the microphone to a microphone preamplifier supplying 48V phantom power using a standard XLR microphone cable. Allow up to one minute for the microphone to settle. Plugging in the microphone "hot" will not damage the microphone and is actually preferred for faster settling. It is normal for phantom powered mic to "pop" when plugged in or powered up. Mute the signal to speakers or headphones when phantom power is first applied.

The excellent performance characteristics of the SR40 give it a very wide range of application possibilities. In the studio or on the stage the SR40 is an ideal choice for a variety of instruments including sax, flute, trumpet, guitar, piano and percussion. It is superior for choir because it doesn't spotlight; rather, it picks up an entire section with no hot spots.

Care of Microphones
Avoid touching the front protective screen. Never attempt to disassemble the microphone and avoid extreme heat and condensing humidity. Allow the microphone to warm up in the case when bringing it in from the cold weather. Rough handling may damage the microphone even if no visible marks are left. When not in use keep the SR40 in its case.
