MA-4HP

microphone  amplifier

The MA-4HP is a high quality microphone amplifier with an integral high-pass filter. The gain range is 8dB to 63dB and the high-pass ranges from 3Hz to 315Hz @ 6dB/oct. This mic amp is transformer-less and there are no capacitors in the signal path. The 3 dB down points are 3Hz and 120kHz and the output clip point is greater than +30dBm As with all of our products, there are two isolated line driver outputs per input signal (Mic or Line).
