  • clicks:942
  • product description:Size: 235*306*90mm
    JPA1024 amplifier module is mainly used for electroacoustic testing, which uses the ultra-low noise OP and Class-A circuit to reject the noise from inputs. It supplies power and plays the role of preamplifier for microphone and artificial mouth.
  • Features:
    ■ It has 3 channels for microphone power supply (+24V)
    ■ It has 3 channels for microphone preamp (0dB/20dB/40dB with 0.01% THD)
    ■ It has 3 channels for 20dB amplifier gain (for artificial mouth and speaker) ■ Output interface: BNC ■ Input interface: BNC
