TRINITY Audio writes: “The TRINITY DAC with its patented LIANOTEC architecture sets new standards so that discerning music aficionados can finally enjoy their most beautiful recordings as if it were the true to life original. The DAC supports the playback of audio files with 44.1kHz – 384kHz sampling rates and 24bit resolution and DSD 64 in a direct DSD mode, which means the DSD signal is not processed inside the DAC.”
The asynchrony USB interface is galvanic de-coupled from the computer side and is synchronized with two full customized, hermetic sealed Voltage Controlled Oven Controlled Xrystal Oscillators VCOCXO, which deliver the 2 master clocks of 44.1kHz*512=22.579200.0MHz and 48kHz*512=24.576000.0MHz.
The exact frequency can be fine-tuned to compensate any aging for the next 20years. The selected master clock is available as a 50Ohm output signal on the back of the DAC. The accuracy is 1ppb or 0.02Hz (factory setting) with a tuning range of +/-1000ppb. The outstanding extreme low jitter is 28fs (10Hz-100kHz).
These VCOCXOs are very low sensitive to any acceleration with 1ppb/g, measured in the worst-case axis.
The sampling frequency (the frequency of the word clock) of all input signals is measured with the help of a real frequency counter. The frequency counter works also for the XLR and SPDIF inputs and is based on an own reference TCXO with 2ppm accuracy.
The TRINITY DAC has its own USB 2.0 Hub inside the DAC.
The Port 1 is used by a USB Memory Stick, which contains the driver, firmware and test tones to check the DAC. Customers can even write own music files on it.
The Hub has its own galvanic decoupled low noise 5V power supply. Therefore, the PC side of the USB interface gets its power supply from the DAC and not from the noise PC.
A further advantage of the USB Hub is that you can easily add additional USB Interfaces.
The DAC is designed as a very modular concept.
It has space for 4 DAC modules, which have all their own XLR connector.
The USB Interface has two separate signal paths. One is for the PCM and another independent path is for DSD. That means you can run 4 different DAC architectures inside one DAC enclosure.
