This compact professional pre-amplifier is specially designed for adding a turntable to a stereo amplifier that has no phono input or to add a microphone input to an amplifier. The microphone pre-amp section is designed to accept both Dynamic or Condenser microphones via a selection switch or a low level input such as guitar or telephone pick up. The phono pre-amp section features an extremely accurate RIAA record compensation response with very low noise and audio distortion. This high gain, low noise pre-amp is ideal for both home and professional studio and broadcast application.
