Item Type: Digital to Analog Fiber ConverterMaterial: PVCInput Interface: Coaxial or for Toslink Digital AudioOutput Interface: L/R, Headphone, Coaxial, for ToslinkFrequency Range: 10Hz-48 KHzOutput Impedance: 16-300Working Voltage: 5VPackage List1 x Converter1 x USB Line1 x Fiber Optic Cable1 x Manual1. This converter does not support 5.1 channels, such as Dolby and DTS.2. There have not an optical output interface for PS4 pro/ PS4 slim, so this converter cannot be used.3. This converter supports digitaltoanalog conversion, but does not support analogtodigital conversion. 4. You cannot control for Toslink or coaxial audio output. 1This DAC converter can convert coaxial or digital audio signals into analog L/R audio, and can be connected to external equipment such as amplifiers through standard RCAtype jacks. 2The twoway switch design makes it more than a DAC converter, not only supports digitaltoanalog conversion, but also supports for Toslink to coaxialand coaxial to for Toslink. 3Builtin highfidelity amplifier chip, L/R and 3.5mm output can drive 16~150 impedance headphone/sound, and the volume control knob is only used to adjust the volume of the headphone jack and RCA jack. 4Equipped with 4.0OD optical cable, coaxial cable and power adapter, no need to install additional programs, just plug and play, please set the audio output to PCM or LPCM. 5You can adjust the volume of the audio output from the RCA L/R+3.5mm jack, and supports sampling rates of 32, 44.1, 48, 96, and 192 KHz, as well as 24bit S/PDIF input bit streams on the left and right channels.
