Active Crossover ACN400
Resistance switching ladder attenuator In a variable resistor that slides on a resistor, noise is generated by a point-contact diode, which can be a source of distortion. This unit is a crossbar twin structure. A gold and platinum contact relay switches the resistance and attenuates. |
Power supply for each left and right A switching power supply that does not generate flux leakage and a fast-response dropper power supply are used to construct a highly stable power supply. |
Unique transformers A unique transformer placed in the signal path cuts noise and allows only the audio signal to pass through without adding anything extra. Both inputs and outputs are equipped with one XLR and one RCA each, and the use of transformers ensures perfectly balanced inputs and outputs. |
