The Benchmark DAC3 B Rackmount Digital to Analog Audio Converter is well suited for many professional studio applications and is the ideal converter to use in front of Benchmark's HPA4 headphone amplifier or LA4 line amplifier. It delivers the full performance of the flagship DAC3 HGC, but eliminates the volume control, the analog inputs, the mute and polarity controls, and the headphone amplifier.

Reference-Quality D/A Converter    Two Channels, 32-Bit Processing    Use with HPA4 or LA4 Amplifiers    Streamlined Feature Set

• The DAC3 B is the basic D/A converter in Benchmark's DAC3 converter series. The DAC3 B is the ideal converter to use in front of Benchmark's HPA4 headphone amplifier or LA4 line amplifier. It is also ideal for many professional studio applications. It delivers the full performance of the flagship DAC3 HGC, but eliminates the volume control, the analog inputs, the mute and polarity controls, and the headphone amplifier.
• To make system integration easy, the DAC3 B retains IR remote control (handset optional), 12 V trigger,  and the programmable auto-on feature. The DAC3 B adds a control-lock feature that turns off the remote control and locks the keypad to prevent tampering and accidental changes. The optional 1/2-width rackmount faceplate allows the mounting of two units in a single 1-RU rack space.
• The DAC3 B sounds exactly like the DAC3 HGC because it uses the exact same circuit board and the exact same audio path. Benchmark has simply eliminated the unnecessary parts to deliver a stripped down race car of a converter. If you want a basic D/A converter that delivers the finest conversion available, the DAC3 B is for you. 
• The DAC3 B  is a 2-channel D/A converter featuring the new ESS Technologies ES9028PRO converter chip. The DAC3 converter has lower THD and THD+N noise than Benchmark's DAC2 converters.
• Benchmark's DAC1 and DAC2 D/A converter families have been the reference to which other converters have been compared. It is rare to find a converter review that does not draw comparisons to the DAC1 or the DAC2. Benchmark converters are in daily use at many of the world's finest recording studios and mastering rooms. Benchmark converters are also enjoyed by thousands of audiophiles. Benchmark has raised the bar again, the DAC3 defines a new reference.

• The DAC3  delivers outstanding musical detail and precise stereo imaging. It employs an advanced high-headroom digital filter design, and a high-sample-rate Asynchronous USB Audio interface. All inputs are fully isolated from interface jitter by Benchmark's new UltraLock3 jitter attenuation system.
• Internal digital processing and conversion is 32-bits, and this processing includes 3.5 dB of headroom above 0 dBFS. This headroom prevents the DSP overloads that commonly occur in other D/A converters.
• Four balanced 32-bit D/A converters are summed together to create each balanced analog output. This 4:1 summation provides a 6 dB noise reduction, and gives the DAC3 industry-leading performance.
