Summit Audio TPA200B
Tube Microphone Preamp

TPA200B

The Summit Audio TPA-200B Dual Tube Preamplifier combines the best of two worlds: vacuum tubes and high quality solid state. This unique combination creates an environment that yields the warmth associated with tubes without the inherent high frequency loss while providing the reliability of solid state components. The TPA-200B is designed to work in a variety of applications using three input types: microphone input, line level input, and front panel Hi-Z input.

Features:

• Mic. Line and Hi-Z inputs
• Uniquely controllable from "Clean" to "Overdrive"
• Front panel Hi-Z input
• Pad Switch & Phase Switch
• 48 volt phantom power
• Jensen input transformers
• Overload and Overdrive indicators
• Hand crafted in the U.S.A.

• Getting a clean microphone signal
• Getting tube guitar distortion
• Getting a warm bass tone

• Output: +4 dBu corresponds to 0 VU. The output iselectronically balanced or unbalanced using 990 operational amplifiers. Outputimpedance is 75. The recommended output load is 600Ohms or more. Maximumoutput level is +25dBu.
• Input: The input is transformer balanced. The micinput impedance is 2 kOhm, the line level input impedance is 20 kOhm and theHi-z input impedance is one mega-ohm. The mic and line inputs are balanced;the Hi-z input is unbalanced.
