Benchmark DAC1 HDR
The DAC1 HDR is a reference-quality 2-channel digital-to-analog audio converter with remote control. The DAC1 HDR features a remote-controlled motor-driven Alps volume control, and relay-selected analog inputs.
DESIGNED, ASSEMBLED, AND TESTED IN THE USA
This Benchmark product was designed, assembled, and tested in the USA using USA and imported components. Most major components are made in USA.
The DAC1 HDR preserves the exact topology and sound of the audio path in the classic DAC1, while adding some of the most frequently requested features.
The DAC1 HDR has all of the features of the DAC1 plus:
Remote control (optional metal IR remote)
High-quality motor-driven Alps volume control
Dim, Mute and Standby functions
Relay-selected analog inputs
USB Audio 1.1 interface (96 kHz, 24 bits)
1 additional digital input for a total of 3 coaxial, 1 optical, and 1 USB
Programmable headphone gain with 3 settings (0 dB, -10 dB, and -20 dB)
Programmable mute switch on left headphone jack
An Industry Standard
Benchmark's award-winning DAC1 has become a standard in the finest recording studios and mastering rooms. Audio engineers rely of the accurate, uncolored, and precise sound of Benchmark DAC1 converters. The DAC1 is free from digital artifacts and its sound has a true analog character that eliminates the fatigue caused by many digital devices. All DAC1 converters are designed for professional applications, but many audiophiles have discovered the smooth and detailed sound of the DAC1. Benchmark's professional DAC1 converters have become a centerpiece in may home listening rooms.
The DAC1 HGC is a reference-quality professional converter that is equally suited for the finest audiophile systems.
HDR-VC™ High Dynamic Range Volume Control
The DAC1 HDR features Benchmark's HDR-VC™ (High Dynamic Range Volume Control). The HDR-VC™ incorporates a high-quality custom-built motorized Alps potentiometer. This motor-driven volume control maintains the dynamic range of the converter over a wide range of volume settings. Competing products usually use a digital volume control or an integrated analog volume control chip. These competing solutions can introduce distortion and noise while reducing dynamic range. Benchmark's HDR-VC™ provides remote volume control without these performance compromises. Reverb tails and delicate musical details are delivered to the analog outputs over a wide range of gain settings.
Professional users may choose to omit the optional remote handset ($100 savings), but they will appreciate the feel, accuracy, and durability of the premium Alps potentiometer. The remote control handset can be purchased separately, and may be added at any time.
Dim and Mute Functions
The remote control includes unique 'Dim' and 'Mute' functions. 'Dim' (quiet) is a special volume setting for low-level playback. The 'Dim' button toggles the DAC1 HDR between 'Normal' and 'Dim' volume settings. Both settings are independently adjustable from the remote, or from the volume-control knob. The DAC1 HDR remembers and recalls your specified 'Dim' and 'Normal' volume settings. This feature is ideal for HDTV users, as it allows you to set your preferred 'Dim' level for commercials, etc. Studio users can use this function to set two independent monitoring levels.
The 'Mute' function fades down the volume to the 'Dim' level before muting and smoothly raises the volume to the 'Normal' level after unmuting.
Five Digital Inputs
With a generous selection of digital inputs (3 coax, 1 optical, and 1 USB), the DAC1 HDR can serve as the heart of expansive media and entertainment system. The DAC1 HGC replaces the low-quality converters that are built into typical consumer devices. The DAC1 HDR will enhance the audio performance of your digital television, digital cable box, DVD/CD player, computer, music/media server, satellite radio, and any other device with a digital audio output. The DAC1 brings studio-quality sound to home listening rooms. Many professional users also appreciate the flexibility provided by the 5 separate digital inputs.
All digital inputs on the DAC1 HDR (including the USB) feature Benchmark's jitter-immune UltraLock™ clock system. The USB interface operates with Benchmark's AdvancedUSB™ native 24-bit, 96-kHz USB technology.
The DAC1 HGC has a pristine analog input path that allows the connection of analog-only devices. The stereo analog input passes through the motorized volume control and out to the analog outputs. This input allows a connection from an analog source such as a phono stage, FM tuner, iPod, VCR, or tape deck. In the studio, this input provides quick access to the studio monitoring system when a client brings a demo on a portable device.
International Power Supply
The large internal power supply supports all international voltages and has generous margins for over and under voltage conditions. The power supply is sized to supply the demands of the HPA2™ headphone power amplifier when driving two sets of low-impedance headphones.
Calibrated or Variable Output Levels
The front-panel gain control sets the output level of the headphone jacks. It can also be used to control the output level of the balanced XLR and unbalanced RCA analog outputs. A rear-panel switch selects "Variable" or "Calibrated" output levels. In the "Calibrated" setting, the rear-panel outputs are controlled by internal multi-turn calibration pots.
Direct Interface to Power Amplifiers
All Benchmark DAC1 and DAC2 converters are designed to directly interface with power amplifiers and powered monitors. The DAC1 HDR features high-current output stages that are designed to cleanly drive difficult loads. The XLR outputs are equipped with Benchmark's exclusive low-impedance passive output attenuators. These attenuators can be set in 10 dB steps (0 dB, -10 dB, -20 dB and -30 dB) to optimize the gain-staging between the DAC and the power amplifier. This important feature maximizes the signal to noise ratio of the entire playback system. At Benchmark, we believe that this is one of the most important features of our converters. Proper gain-staging is an absolute necessity in a high-performance system.
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, generating 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 HDR (using state-of-the-art testing equipment by Audio Precision). UltraLock™ will block more then 12.5 UI of jitter (@ 1 kHz). The UltraLock™ clock system easily outperforms even the best-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 HDR 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. The DAC1 HDR achieves transparent, audiophile-quality playback through a true plug-and-play solution.
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 HDR is natively compatible with most Windows, Mac, Linux, and Android operating systems. As a native device, there are no drivers to install or configure.
Add Benchmark Cables to Complete You New System
Benchmark offers a no-nonsense selection of very high-quality cables. Benchmark cables are designed for durability and transparency, and most are manufactured in the USA. Our optical cables are manufactured in Canada.
Add a Rack-Mount Kit
All Benchmark DAC1, DAC1, ADC1, and MPA1 products are housed in a 1/2-wide 1 RU chassis. Two units can be mounted side-by-side in a 1-RU tray.
HPA2™ Headphone Power Amplifier
The DAC1 HDR includes the HPA2™ - Benchmark's signature high-current, 0-Ohm headphone power amplifier. The HPA2™ is 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 HDR has two 1/4" headphone jacks on the front panel.
