beresford - tc-7510 DAC - Digital Analog Converter

This converter features four high-quality digital inputs (two optical and two RF/coaxial), any of which can be selected to feed the parallel analog RCA outputs and the headphones.

Use the TC-7510 when you need to add 4 digital inputs to a fully analog receiver or amplifier, or to provide 4 digital inputs when the existing ones are insufficient or of low quality. It can also serve as a standalone headphone amplifier, or to enable headphone control from a digital source while the main amplifier sends a different source to the speakers. Finally, the converter can be used to add a digital input to any type of analog amplifier.

The TC-7510 easily outperforms the low-resolution Digital-to-Analog Converters used in inexpensive and mid-priced receivers and audio amplifiers, delivering a wider dynamic range and superior musicality.

Specifications
- Selection of one digital input from among four (two optical, two RF)
- 2 analog stereo outputs and 1 stereo headphone output
- A robust and elegant metal finish
- Digital-to-Analog Converter Studio, reference quality from perhaps the most famous name among makers of Digital/Analog integrated circuits
- Exceptional built-in headphone amplifier consisting of a low-noise dual 5532 op-amp in Class A, used in many studio audio mixing devices to ensure analog integrity at the output stage
- Included digital chipsets: an input receiver CRYSTAL CS 8414 and a BURR-BROWN PCM 1716 96KHz/24 bit converter.
- 2 AES/EBU coaxial inputs and 2 optical inputs (Toslink) provided.
- 2 analog outputs via stereo RCA jacks:
1. A variable output whose level can be controlled via the volume control on the front panel,
2. An output with a fixed line level.
- A separate external power supply ensures that the TC-7510's excellent signal-to-noise performance is not compromised by hums or other external noises.
- Including an AC/DC power supply with a selectable 1.7 A mode that offers better audio performance.
