DAC2 DX - Reference Stereo Preamplifier / PCM and DSD D/A Converter / Hdph Amp / Async

The Digital-Only DAC2 for Audio Professionals

Includes Asyncronous USB Audio technology, High-Current Output Drivers, AES/XLR Input. Remote Control optional.

The DAC2 DX is the DAC2 of choice for users who do not need analog inputs.

The DX is well suited to the needs of professional users and includes an XLR AES digital input. The DAC2 DX is the only DAC2 model that includes dual stereo output buses. The analog output buses can be independently set to fixed or variable gain. The DAC2 DX is also the only DAC2 available with in a rack-mount version.

Benchmark Performance

The DAC2 DX is Benchmark's newest 2-channel D/A converter.  When compared to the legendary DAC1, the DAC2 has lower noise, lower distortion, and improved accuracy. The DAC1 became a reference standard in many of the finest recording studios and mastering rooms.  The DAC2 defines a new reference.

DAC2 converters deliver outstanding musical detail and precise stereo imaging.  They employ an advanced high-headroom digital filter design, and a new high-sample-rate Asynchronous USB Audio interface. All inputs are fully isolated from interface jitter by Benchmark's new UltraLock2™ jitter attenuation system.

Internal digital processing and conversion is 32-bits, and includes 3.5 dB of headroom above 0 dBFS. Three balanced 32-bit D/A converter are summed together for the main output bus. Two channels are reserved for the auxiliary RCA output bus.

The performance of the DAC2 DX exceeds the measurement limits of today's state-of-the art test equipment.

Native DSD Conversion

DSD (in DoP 1.1 format) is automatically detected on USB, coaxial, and XLR digital inputs. The system seamlessly switches between native DSD and native PCM conversion. DoP 1.1 is supported by many media players, and DSD downloads are now available from several sources.

Enjoy seamless transitions between native DSD and native PCM playback.

Direct Connectivity to Power Amplifiers and Powered Monitors

Benchmark DAC1 and DAC2 converters are designed to directly drive power amplifiers and powered speakers.  Benchmark converters feature adjustable low-impedance passive attenuators at the XLR outputs that can be used to optimize the interface to the power amplifier (or powered monitor). The sonic importance of these attenuators cannot be overemphasized. Proper gain matching between the DAC/preamplifer and the power amplifier is essential for achieving peak system performance. The attenuators allow precise matching to all amplifiers and powered monitors.

Passive output attenuators are only found on Benchmark converters - don't settle for anything less.
