Radius will launch a small portable headphone amplifier "RK-DA60C" with a DAC-equipped portable headphone amplifier that supports high-resolution playback of 384kHz/32bit from mid-October.The price is 8,250 yen (tax included).A portable headphone amplifier equipped with a DAC that supports USB-C connection to Android devices with USB-C.While the previous model "RK-DA50C" was supported up to 192kHz/24bit, the performance was enhanced to 384kHz/32bit compatible with this model.In addition, the playback frequency band is 20Hz -90kHz to 20Hz -160kHz, and the maximum output is 57..6MW+57.6MW to 66.8MW+66.I improved the specifications to 8MW. The chips are "CX31993", which is equipped with one DAC on the left and right channels to secure left and right separation, providing clearer sound quality and spatial expression. In addition, the CX31993 has been able to efficiently design and miniaturize the tip by adopting the same tip to provide an efficient substrate design and miniaturized to achieve a small and lightweight design of 6 g of mass. The G -class headphone amplifier is used as a portable amplifier. When the entered signal level is low, the power supply voltage is reduced to reduce the power supplied to the headphones, and when the signal level is high, the power supply voltage is increased to supply more power, reducing the current consumption of the connected device. The use of an optimized power supply voltage will always provide high -quality music regardless of the output volume. In addition, the body operates without charging because of the bus power drive. The cable is a single crystal copper cable with silver plating. 3 as an earphone terminal.Equipped with a 5mm stereo jack, it has a function to determine the presence or absence of a remote control of the earphone and headphones when connected, and the control interface built into the chip allows the remote control to be connected to a PC or smartphone.Equipped with an ADC that can input audio from the earphone microphone with a maximum of 96kHz/24bit, it appeals that a clear and high -quality call is possible.THD+N is ≧ 0.001%, S/N
