Default Gain Module with Current Transmission Technology

It can work in Zero Feedback or Current Feedback
This gain module has self-biasing and current transmission gain features; with these features it has an extreme wide voltage range as well as a loose requirement of power supply. It can achieve very low noise level even without stabilized voltage power supply, and it differs from other zero-feedback amplifiers which will make much noise without stabilized voltage power supply. The current transmission technology adopted by Krell on its top-level products makes it extraordinary. The current transmission technology avoids disadvantage of common transistor amplification circuit, it has excellent linearity and signal regeneration even completely without feedback. If working under current feedback mode, you could tell the change of sound.

Default Hi

This gain module can input the RCA signal ,and output the current signal (SATRI),
If it input the XRL signal, then it can output CAST,
If you want input CAST signal, or you can use the BPM7110 gain module,
When BPM-7110 are applied to manufacture preamplifier with CAST technology, the gain and volume of the circuit are able to adjust synchronously. This brings higher SNR and lower distortion. It wont cause overdrive distortion within the effective output range even when the circuit gain is a bit high.
