FX-AUDIO- DAC-T3J: Integrated DAC with headphone amplifier and tone control preamplifier, supports 3 digital inputs, and is Hi-Res compatible.
Integrated DAC with headphone amplifier and tone control preamplifier, 3 digital inputs, and Hi-Res audio support.
FX-AUDIO- DAC-T3J
For the heart of the system, we've chosen the high-performance, highly regarded ESS Technology "ES9018K2M" DAC IC, which is compatible with high-resolution audio!
Utilizing an IC with a proven track record in performance-oriented professional audio equipment and a strong reputation for sound quality, this device achieves excellent sound separation across the entire frequency range, resulting in high-resolution and clear sound quality.
The headphone amplifier uses the high-performance headphone amplifier IC "MAX97220," achieving high sound quality with excellent THD+N characteristics across the entire frequency range, even with low-voltage operation.
It features a tone control function, allowing you to adjust the balance of high and low frequencies to suit the sound source and your preferences.
The RCA output is also volume-controlled, making this an integrated DAC that can be as a DAC, tone control preamplifier, and headphone amplifier all in one unit.
By connecting it to a simple power amplifier with only analog inputs, you can add digital conversion, 3-input switching, tone control, and headphone amplifier functions.
This item allows you to add functions to the DAC that are not present in the amplifier, expanding the range of applications for the entire system.
It supports PCs, mobile operating systems (Android/iOS), and even some game consoles (PlayStation)!
The power connector uses a highly versatile USB Type-C connector, so you can use your existing adapter and cable without having to purchase a separate AC adapter.
This eliminates the cost of purchasing a separate AC adapter, allowing you to utilize any spare USB adapters or cables you may have. *If you do not have these, please purchase them separately.
*This product is a DAC with a built-in preamplifier function, so unlike typical DACs, the RCA output is linked to the volume control.
*The RCA output automatically stops when headphones are plugged in.

■ Differential converter operational amplifier: Texas Instruments "NE5532" (DIP)
[Notes]
*The USB Type-C connector is for power supply only. It cannot be for USB digital signal input, so please use the Type-B connector for USB connections.
*This device does not support bus power operation, so please be sure to connect the USB Type-C connector to a USB port capable of supplying power using a cable.
*Whether or not high-resolution signals can be transmitted depends on the hardware and software specifications of the device connected as a playback device.
While this product itself is Hi-Res compatible, Hi-Res playback will not be possible if the connected device or software does not support the transmission of Hi-Res signals.
