供应CPI P631前置&后级放大器

PRODUCT DESCRIPTION
The microphone preamplifier P631 has been designed to match CPIˊs microphone
M620FA, M620FB, M620FS and M620PA. It also can match artifical mouth M610C with a one way post-amplifier. P631 power supply the microphone connected to its input with an 8.2V and 24V phantom supply and adds a selectable weighting filter (A ); also available there is a 20 dB gain stage.
The Power Amplifier is designed to fulfil the needs of an electro-acoustical analyzer to amplify audio.Using the Power Amplifier for frequency response measurements acts as 25W power amplifier to drive the speaker or artifical mouth.
