AVT2728 B

The universal microphone amplifier can work directly with popular two- and three-pin electret microphones. Very good sound quality has been achieved: thanks to the use of high-performance components: tantalum capacitors and the NE5532 low-noise operational amplifier. Thanks to this, the module has such good parameters that it is perfectly suited to working with good quality dynamic microphones.

The device is especially recommended for electroacoustics and musicians

Selected parameters:

• nonlinear distortions <0.09% (at maximum amplification)
• frequency response> 25 kHz
• the possibility of adjusting the gain in the range of 0.9-100x
• regulation of step and liquid gain
• power circuit for the electret microphone
• power supply - 6-25 V (battery or accumulators)
• set of elements and documentation included
