Input/output balance terminal volume controller from SPL (German recording professional equipment manufacturer). By designing an active circuit, it is possible to avoid a decrease in linearity due to changes in impedance that occur in passive circuits. The volume is continuously variable, and there is almost no imbalance between left and right, and it expresses a high level of sound quality. The exterior is dull, and there is a feeling of use such as small scratches. Serial 7020595 (Asaina Satoshi method)
