What is a Digital to Analogue Converter (DAC) ?
A Digital-to-Analog Converter (DAC) is an essential electronic component in digital audio devices. Its role is to convert digital signals into analog signals, enabling sounds to be reproduced through loudspeakers or headphones.
The use of a DAC enables the conversion of a digital signal into a precise analog signal, reducing unwanted distortion and providing a clearer frequency response. Some offer the possibility of programming options to suit your personal preferences.
The Digital-to-Analog Converter replaces the internal converter and offers the opportunity to improve the conversion of a sound signal to make it more efficient.
There are three types of Digital-to-Analog Converter:
- Integrated into a HI-Res Audio nomad player. Bathys headphones feature this audio conversion system.
Aspects
| Advantages | Disadvantages |
Quality | Better sound quality and no compression | |
Channel separation | Improves clarity and separation of instruments | Requires high-quality audio files |

- Separate unit (mains or battery), with volume control and sometimes usable as a preamplifier.
Aspects
| Advantages | Disadvantages |
| Power | High output power | Depends on mains or battery supply |
| Power supply | Constant power supply | Less portable due to need for a power source |
Sound quality | Better audio quality | More bulky and expensive than more compact models |
| Connectivity | More expensive quality options | Requires mains plug or recharging |
