The STM-3 is part of the group of "STICK-ON" products from Radio Design Labs. The STM-3 is a quality microphone preamplifier designed for use in commercial sound, broadcast, and recording applications. Its compact size makes it ideally suited for locations where a larger or heavier preamp cannot be used. Its performances makes it the best choice, even when larger preamps could be used! The single-ended supply input makes the STM-3 the ideal choice for both permanent and mobile equipment installations. Some features of the STM-3 are:
- Balanced microphone input accepts impedances from 150 to 600 ohm
- Input circuitry permits connection of unbalanced microphones, or even 4 or 8 ohm speakers in intercom or monitoring applications
- Variable gain (up to 75 dB) and ample headroom allow operation with any microphone
- Phantom supply input terminals allow connection of external power when STM-3 is used with phantom powered microphones
- Supply input is single-ended and operates from 12 Vdc to 33 Vdc
- Two separate outputs are provided for balanced 600 ohm or unbalanced 10 kohm
- No lugs required for reliable connections
Power supply is required.
