This product is fulfilled by seller
K157UP1A microcircuits are two-channel microphone amplifiers with two-channel recording preamplifiers. They provide amplification of signals from 160 mV and 10 mV, applied respectively to the microphone input and the input of the preamplifier of recording, to the standard level of the microphone linear output equal to 250 mV. High overload capacity (over a microphone input over 36 dB and a 16 dB preamp input) allows the use of ICs in low-frequency paths with automatic gain control (AGC). The difference between K157UP1 and K157UP2 is that the first requires the use of AGC regulating elements with a positive controlled voltage, and the second with a negative one. Contain 63 integral elements.
