Manufacturer's Description from Josephson


Josephson Series Five microphones are rugged, stable and cost-effective alternatives to high voltage metal diaphragm lab mics for speaker testing, room acoustics, and general audio measurements between 20 Hz and 20 kHz. The 6mm condenser capsule has a permanently polarized backplate and a 3.5 polyester diaphragm, metallized with a rugged nickel- chromium alloy. Frequency response is flat -+2 dB from 20 Hz to 20 kHz. Like all Josephson mics, the diaphragm is critically conditioned during manufacture for minimum drift over time. Series Five mics have been in rugged field service for more than ten years, with little or no change in response. Several versions are available for use with a variety of other equipment.

The C550 series is a "half inch" model available in three sensitivity steps, each one covering an operating range of about 100 dB. The C550H provides 10 mV/Pa output, suitable for microphone level inputs. The L version is more sensitive, for use with line level inputs, while the F version has lower sensitivity for use in high sound pressure level measurements. Frequency response is flat for on-axis sound incidence, but any of the models may also be supplied with a -D suffix for flat diffuse field response. All models may be powered with 24 to 48 volt phantom supplies, and provide symmetrical active balanced outputs. They will also operate on phantom power as low as 15V with some reduction in maximum level.

For more critical applications, please refer to model C617 in the Josephson Series Six, which has lower noise and higher overload point than the Series Five, uses lab grade metal diaphragm mic capsules, and standard phantom power rather than the dedicated power supply required for most lab mics.

About Manufacturer

Josephson Engineering makes a wide range of fine condenser microphones for studio, stage and field sound pickup, and audio instrumentation. The company began in San Jose, California in 1988 and moved to Santa Cruz in 2000. This is our 20th year of producing microphones. In the process of developing our own mics, we've come up with special technologies that let us realize designs that weren't possible in classic mics of years past. This means that the expert user has a wider range of sound choices, without many of the compromises of older designs. Besides our own production, we also supply microphone capsules to several other mic manufacturers that become the mics for their most demanding customers. All of our business is individual -- we use select local dealers who bring our product directly to critical users around the world. We have a standard product line that covers many applications, but if there's a microphone you need that we don't make, we'll either tell you about the best one we know of for that job, or make it for you ourselves. We won't tell you that one of our mics is good for everything -- there's no such thing. Josephson also provides electro-acoustical engineering, design and manufacturing services for challenging requirements in many industries, specializing in microphone transducers and supporting systems. Our OEM capabilities have allowed several companies to excel in their own markets, using capsules made by Josephson.
