Know before you buy
Yes, the DAC1 HDR is designed to serve as a preamplifier. It features a high-quality motorized Alps volume control and high-current output stages, allowing you to drive power amplifiers or powered monitors directly without needing an external preamp.
The USB input supports up to 24-bit/96 kHz audio. It uses a plug-and-play USB 1.1 interface, which does not require specialized drivers for most modern operating systems.
The UltraLock clock system is designed to be virtually immune to jitter. By effectively isolating the audio signal from timing errors in the digital source, it ensures the output remains clean, accurate, and free from the distortion often associated with jitter.
The integrated HPA2 headphone amplifier is highly capable and features three programmable gain settings. This allows you to optimize the output for a wide range of headphone impedances, ensuring clean, high-current delivery even for demanding models.
While primarily a digital-to-analog converter, the DAC1 HDR includes relay-selected analog inputs. This allows you to integrate an analog source into your system and utilize the unit's volume control and output stages.
As a legacy product, the DAC1 HDR is known for its robust build quality and professional-grade components. However, because it is no longer in production, ensure the unit is in good working order and verify that your current computer's operating system remains compatible with the USB 1.1 interface.
