Teave:

The black DAC3-L from Benchmark is a two-channel reference preamplifier with a built-in digital to analog converter system. It is capable of converting Direct Stream Digital (DSD) signals as well as Pulse Code Modulation (PCM) files up to 24-bit / 192 kHz. Designed as an output device for computer-based media, the DAC3-L can be used with home media servers, digital audio workstations, desktop audio editing applications, and computer-based radio broadcast systems. The DAC3-L maintains the familiar DAC2 form factor and feature set, but delivers the higher performance available from the ES9028PRO D/A converter chip.

The 8-channel/32-bit ESS Technologies ES9028PRO chip features two distortion compensation systems, which independently remove most of the 2nd and 3rd harmonic distortion in the D/A converter. It also uses 4:1 summing to form each of the two output channels. This results in an enhanced frequency response and a 6 dB signal to noise improvement with low THD and THD+N noise.

The DAC3-L follows sample-rate changes initiated by your computer or software and uses a multimode asynchronous USB system for data transfer. This allows the unit to act as the clock master, reducing jitter by first transferring the audio data from your computer to an internal buffer, and then to the digital to analog subsystem. The dual data transfer uses Benchmark's proprietary UltraLock3 jitter attenuation system, reducing jitter noise and distortion to at least 140 dB below the level of the audio.

The Hybrid Gain Control (HGC) combines the unit's active analog gain control, passive low-impedance attenuators, 32-bit digital gain control, and servo-driven volume control. The HGC provides the dynamic range of an analog system and the accuracy of digital control. All analog inputs are controlled in the analog system and digital inputs in the digital system. The 32-bit Digital Signal Processing (DSP) also provides up to 3.5 dBFS excess digital headroom throughout the entire conversion process.

The DAC3-L features a variety of input and output options including two stereo unbalanced analog RCA inputs, two optical TOSLINK digital inputs, two coaxial digital inputs, one USB digital input, two stereo analog unbalanced RCA outputs, and one stereo analog balanced XLR output. It is compatible with the Benchmark IR remote control (available separately).
2-channel D/A converter designed for maximum transparency—converters are ideal for critical reference-quality professional systems
8-channel/32-bit ESS Technologies ES9028PRO converter chip uses 4:1 summing to form each of the two output channels—achieves a 6 dB signal to noise improvement with low THD and THD+N noise
ES9028PRO features two distortion compensation systems that independently remove most of the 2nd and 3rd harmonic distortion in the D/A converter
High-headroom DSP is designed to handle signals as high as +3.5 dBFS in the entire conversion system and prevents common DSP overloads
All digital inputs support native PCM or DSD conversion
All inputs are fully isolated from interface jitter by Benchmark's UltraLock3 jitter attenuation system
Hybrid Gain Control system combines active analog gain control, passive low-impedance attenuators, 32-bit digital gain control, and a servo-driven volume control—all inputs are controlled by the rotary volume control, which also moves in response to commands from the remote control (included)
Analog inputs are never converted to digital, and digital inputs never pass through an analog potentiometer
Digital inputs are controlled in the 32-bit DSP system to preserve precise L/R balance and precise stereo imaging, while avoiding any source of noise and distortion
USB system supports USB Audio 1.1 for sample rates up to 96 kHz and USB Audio 2.0 for high-resolution 192 kHz and DSD playback—system is frequency agile and will follow sample rate changes initiated by the computer and/or the media playback software
Sample-rate and word-length displays confirm the proper operation of your media player
High-fidelity preamplifier includes input selection, volume control, and output buffering functions—high-current output stage can be programmed to match the input sensitivity of your power amplifier or powered speakers
Programmable Home Theater Bypass function sets the pass-through gain to unity for integration of a home theater audio system via the RCA inputs
Second coaxial input can be reconfigured as a digital output—in output mode, any selected digital input, including USB, will pass through to the coaxial output
12-volt trigger connection can be used as an input, output or both, and is compatible with any common 12-volt trigger input or output—the trigger can be used to turn a power amplifier on or off automatically or respond to a 12-volt trigger and follow the actions of another audio component
Distributed power supply regulation to achieve the lowest possible noise—each critical subsystem has at least one dedicated low-noise voltage regulator
Compatible with Benchmark IR remote control (available separately)—all functions can be controlled from the front panel or from the remote
Designed, assembled, and tested in the USA using USA and imported components—most major components are made in the USA
