DAC1 PRE - Listen and the Music will Engage You
Stereo Pre-Amplifier / DAC / Headphone Power Amp
The DAC1 PRE is a reference-quality stereo pre-amplifier, headphone power amplifier, and computer audio playback device (USB DAC), incorporating the 24-bit, 192-kHz DAC1 digital-to-analog conversion (DAC) system. With the DAC1 PRE, the music engages the listener breath-taking realism.
The DAC1 PRE is the culmination of years of high-precision analog and digital audio circuit design. Benchmark has achieved unprecedented sonic purity in their audio systems through an intelligent engineering philosophy - establish a pristine analog delivery path and eliminate digital distortion artifacts. The DAC1 PRE continues this tradition of excellence.
With six stereo inputs and four stereo analog outputs, the DAC1 PRE anchors expansive media systems and provides a pristine audio path from source to amplifier. The six stereo inputs include an analog input, a USB computer input, an optical input, and three coaxial digital inputs. The output section includes stereo XLR balanced, RCA unbalanced, and two headphone jacks driven by Benchmark's HPA2 ™ 0-ohm headphone power amplifier.
The acclaimed DAC1 D-to-A conversion system
Engineers and audiophiles have grown to rely on Benchmark for critical digital audio conversion for more then 10 years. They are consistently finding themselves engaged in the music when using Benchmark digital analog converters - engaged in a way that is rarely achieved with digital converters.
The superior performance of the award-winning DAC1 has made it the 'Benchmark' of D-to-A converters. The DAC1 PRE gracefully merges the DAC1 conversion system with elegant analog circuitry, Benchmark's HPA2™ 0-ohm headphone power amplifier, and essential features and functions.
Jitter-Immune UltraLock™ Clock System
Benchmark’s proprietary UltraLock™ clock system achieves an unprecedented immunity to jitter. Many modern (and expensive) converters suffer from significant jitter-induced distortion. If jitter is not effectively addressed, a converter will generate non-musical sideband tones and digital distortion. Benchmark’s highly-regarded UltraLock™ clock system ensures that jitter is never a problem, even under extreme conditions.
Even in the presence of extremely high input jitter, no jitter-induced artifacts can be detected on the outputs of the DAC1 PRE (using state-of-the-art testing equipment by Audio Precision). UltraLock™ will block more then 12.5 UI of jitter (@ 1 kHz). With the UltraLock ™ clock system, the D/A conversion-clock in the DAC1 PRE is totally isolated from the clock of the digital audio source. The UltraLock ™ clock system easily outperforms most well-designed two-stage PLL designs.
The bottom line is this: Benchmark converters will consistently and faithfully deliver truthful audio without jitter-induced artifacts, no matter what variables are present.
AdvancedUSB™ Audio Technology
The USB interface of the DAC1 PRE operates with Benchmark’s unique AdvancedUSB™ technology. Unlike many USB equipped D/A converters, Benchmark's AdvancedUSB™ technology supports 24-bit audio at sample rates up to 96 kHz without the installation of any drivers or other special software. Benchmark’s UltraLock™ clock system isolates the converter from the high levels of jitter that are found on USB interfaces. AdvancedUSB™ responds automatically to sample-rate changes to bypass the operating system’s sample-rate conversion. The DAC1 PRE achieves transparent, audiophile-quality playback through a true plug-and-play USB DAC.
It is very important to have a 24-bit USB path, even for 16-bit playback, because digital volume controls and other DSP function s can increase 16-bit audio to 24 bits. If a 16-bit USB DAC is used, up to 8 bits of each digital audio sample will be truncated resulting in significant, non-musical digital distortion at audible levels.
Audio streamed via USB is subject to significant amounts of jitter. The AdvancedUSB™ interface utilizes the UltraLock™ clock system. Consequently, the performance of the USB input is equal to the performance of the other inputs, regardless of the jitter present. The DAC1 PRE is natively compatible with Windows 7/Vista/XP/2000 and Mac OS X. As a native device, there are no drivers or other software required to install or configure.
HPA2™ Headphone Power Amplifier
The DAC1 PRE includes the HPA2™ - Benchmark's signature high-current, 0-Ohm headphone power amplifier. The HPA2™ is arguably the ultimate reference headphone power amplifier. It will deliver the full rated performance of the DAC1 to the headphones. The HPA2™ maintains less than 0.0003% THD+N under a full load from two sets of headphones. The DAC1 PRE has two 1/4" headphone jacks on the front panel.
