**ONE ONLY!**
The Opus 83 is a studio condenser microphone suitable for instrument miking. Employing back electret technology, its wide frequency response of 40 - 20,000 Hz combined with a slight proximity effect makes it suited for all formats of recording. Its cardioid polar characteristics are similar to higher priced studio microphones, capturing the sound required with the greatest of ease. Housed in a robust brass body, it easily withstands the rough and tumble of studio use. The 83 handles a maximum SPL of 138 dB at 1 kHz with a THD of 1%, a signal-to-noise ratio of 60 dB relative to 1 Pa and operates between 12 and 48 V from a phantom power supply.
