Compact and dynamic optical compressor. The SN-15 has a wide input signal dynamics, making it suitable for receiving a large variety of signals up to 2V RMS. Feature that gives the device a highly linear behavior for most of the input signals. With the controls it has on board it is also recommended to use it in the studio. The preamp stage does not introduce variations to the output signal, which maintains the same characteristics as the original signal. The internal buffer improves impedance matching for optimal use with other devices such as effects or amplifiers. Graphic indicator of the standard compression threshold.
