Benchmark 500-15200-400 overview

  • 1Description

The black DAC2 L Digital to Analog Audio Converter from Benchmark is a low noise, low distortion 2-channel digital to analog converter. This DAC2 converter features two unbalanced RCA stereo pair inputs, two digital audio channel inputs, and two analog balanced outputs. The DAC2 L system supports multi-mode asynchronous USB system. It employs an advanced high-headroom digital filter design and a high sample rate asynchronous USB audio interface with each input fully isolated from interface jitter using the company's UltraLock2 jitter attenuation system. The device performs 32-bit internal processing and conversion and includes 3.5 dB of headroom above 0 dBFS. Each Balanced output is the sum of four balanced 32-bit converters.

All digital inputs on the converter support native DSD conversion. The DoP1.1 open standard is automatically detected by the device on all inputs and the system seamlessly switches to native DSD conversion. The DAC is designed to directly drive power amplifiers and powered speakers. The XLR outputs of the converters feature adjustable low-impedance passive attenuators that can be used to optimize the matching of the converter to the power amplifier or powered speaker. Sonically, the converter has been designed for maximum transparency making it appropriate for professional reference and Hi-Fi critical listening applications alike.

The converter combines active analog gain control with passive low-impedance attenuators, a 32-bit digital gain control, and a servo-driven volume control. Each of the inputs can be controlled by the rotary volume control which also will move in response a remote control (sold separately). None of the digital inputs are ever allowed to pass through an analog potentiometer, and are instead controlled by the unit's 32-bit DSP system for precise L/R balance and imaging with minimal distortion or noise. The passive output attenuators provide gain reduction without compromising the dynamic range of the converter.

The device's Ultralock Jitter attenuation system uses 32-bit DSP processing with 3.5 dB of headroom and a sample rate of 211 kHz to reduce jitter to at least 140 dB below the level of the music and well below the threshold of human hearing to eliminate audible jitter artifacts. The DSP can handle digital signals as high as +3.5 dBFS because the inter-sample peaks found in many commercial releases as the result of signal interpolation can sometimes exceed the 0 dBFs threshold of individual sinusoidal wave samples.

The device's USB system supports USB Audio 2.0, DSD, and USB Audio 1.1. The frequency agile design allows the converter to follow sample rate changes initiated by the computer or media playback software while retaining asynchronous conversion to eliminate unnecessary sources of jitter.

The master clock of the device has a low-jitter design which controls the transfer of audio from the computer to the USB sub-system, then to a buffer in the DAC, and then to the D/A conversion sub-system. This second asynchronous transfer eliminates any traces of jitter that may accumulate as the data is transferred between the USB and conversion subsystems. The synchronous USB system supports USB Audio 2.0 for high resolution 192 kHz and DSD playback. No drivers are required on Mac operating systems and an easy to install driver adds both 192 kHz and DSD capabilities to Windows operating systems.

An Asynchronous driverless USB Audio 1.1 mode can be enabled from the front panel or from the remote control (sold separately) to allow quick plug and play connections to Windows, Mac, iOS, and Linux operating systems. Even when the DAC is powered down, the USB subsystem will remain active to prevent interruption of computer operations and eliminate the need to reconfigure the computer every time the device is turned on.

Quad 32-bit Balanced Conversion System
Uses four balanced 32-bit D/A converters to deliver 4:1 redundancy which reduces noise and distortion
Diagnostic Tools - Sample-Rate and Word-Length Indicators
Displays sample-rate and word-length to confirm the proper operation of your media player
Polarity Switch
Inverts the polarity of the signal to solve phase related problems
Home Theater Bypass
Sets the pass-through gain to unity when the surround system is active
Digital Pass Through
Allows any selected digital input (including USB) to pass through to the coaxial output in bit transparent formats including DSD (DOP 1.0), Dolby Digital, and DTS
Power Switch
Sets the convert to standby or shut down mode with power consumption less than 0.5 W in full shut down
Low Power Consumption
Uses high-efficiency low noise power supplies that may be operated from any standard international voltage without adjustment
Distributed Power Regulation
Uses distributed power supply regulation of each critical subsystem with at least one dedicated low-noise voltage regulator
