Microphone Pre-amplifiers

THAT Corporation produces a range of high performance preamplifiers with impressive audio specs designed for microphone amplifiers, but equally suitable for use in sonar and for bus summing in audio mixers.

The latest pre-amps from THAT use external gain setting resistors, which gives two significant benefits over original types such as the 1510. The first option is to use a digital gain controller, which enables the functionality expected by users today (for example, controlling their audio gear with a tablet or computer). The second benefit is lower noise at low gain, as the feedback resistors are external and are optimised to reduce noise over a wide gain range

The 1510 and 1512 also remain popular today, being pin compatible with the SSM2017, SSM2019 and INA217, but perform better overall. To see a detailed performance comparison follow the link below.
