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
