Product Description

Copland DAC 215 – Universal High-Resolution DAC, PRE-Amplifier, Headphone Amplifier

Many audiophiles people consider their personal computer or laptop to be their primary audio source based on the ease and excellent sound quality of digital music files performed from a computer. The Copland – DAC 215 analyzes audio data at extremely high resolution while connected to a computer, and playback quality is mainly determined by the data itself.

The ES9018 Reference 32-bit DAC in quad mono, 8 mono to 2 stereo format is at the core of the DA215’s D/A converter, which has numerous S/PDIF inputs, PCM, and DSD capabilities.

The statistical properties of the signals are taken advantage of by combining four in-phase and four opposite-phase converters per channel; the signal power of the phases correlates and add-up in constructive addition, whereas the noise power of the phases is de-correlated, improving the signal-to-noise ratio of the resulting analog waveform.

The generally regarded Copland CD players inspired the Class A buffering technology. It has incredible sound quality, as well as free movement and acceleration.

Aesthetic Design Copland – DAC 215

The DAC215 does have an asynchronous USB input, four S/PDIF digital inputs, an analog input, two analog outputs (fixed and variable), a full pre-amplifier with analog volume control, and a front-panel headphone output with vacuum tube gain stages.

The Amplifier can use to play music using headphones. However, you can connect the amplifier’s RCA outputs to use it as a high-end pre-amplifier with volume control.

For pure DAC mode, the volume control and pre-amplifier functions can bypass for pure DAC mode. The USB 2.0 PCM 24/32 bit data transmission to 384 kHz on the DA215 USB input implementation includes native DSD64 and high-resolution DSD128.

The input converts to i2s and connect directly to the DAC chip. As soon as he is connected, the computer recognizes the DAC and sends the digital audio data to him. Avoiding the internal audio circuitry of the source device.

The asynchronous USB-B port links to the USB-A port on the Computer. The Computer does not drain power. The USB input section’s regulated power supply has its own power transformer winding. The loud computer line entirely stopped by the use of digital Isolators.
