Benchmark DAC3 B Digital to Analog Converter (Silver Rack Mount) Benchmark

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.

The DAC3 B is a professional reference-grade audio digital to analog converter with a fixedgain output. The DAC3 B supports 24-bit D/A conversion of PCM at sample rates up to 192 kHz. It also supports direct conversion of 1- bit DSD at a 2.8224 MHz sample rate. It is designed to be very transparent and this makes it well-suited for critical monitoring in studio control rooms and mastering rooms.

Features:

• Fixed Gain Calibrated Outputs – XLR outputs are calibrated to +24 dBu at 0 dBFS (pads at 0 dB), RCA outputs are calibrated to 2 Vrms at 0 dBFS (calibration is equivalent to “HT MODE” or “CALIBRATED MODE” on other DAC3 models)
• CONTROL LOCK – Disables keypad and remote control to prevent accidental changes
• Low-Impedance Passive Output Pads – 0, 10, and 20 dB – optimize output level to power amplifiers and other downstream devices to maximize system SNR
• SABRE PRO – 32-bit PCM D/A conversion system, four 32-bit D/A converters per channel
• SABRE PRO – Native DSD D/A conversion system, four 1-bit DSD D/A converters per channel
• Benchmark UltraLock3™ Jitter Attenuation System – eliminates jitter-induced distortion
• High Headroom DSP – provides 3.5 dB of analog and digital headroom above 0 dBFS to completely eliminate the clipping of intersample peaks
• Multi-Mode Asynchronous USB Audio 2.0 – 24 bit/192 kHz, DSD (DoP 1.1)
• Driverless Asynchronous USB Audio 1.1 – 24-bit/96 kHz
• Sample Rate Display – displays the measured sample rate, and format (PCM or DSD)
• Word Length Display – displays the measured word length
• 2 Coaxial Digital Inputs – 24-bit/192 kHz PCM, DSD (DoP 1.1)
• 2 Optical Digital Inputs – 24-bit/96 kHz PCM
• 1 Coaxial Digital Output – digital pass through from USB, Coax, and optical inputs when function is enabled
• 2 Stereo Analog Outputs – 1 pair balanced (XLR), plus 1 pair unbalanced (RCA)
• IR Remote with metal housing provides control of all functions (optional)
• Automatic De-Emphasis – automatically responds to consumer pre-emphasis bit (44.1, 48 kHz)
• 12V Trigger I/O – bi-directional 12V trigger can act as input, output, or both
• AUTO-ON Function – can be programmed to turn on when AC is applied
• Power Switch – very low standby power , <0.5 W at 120 VAC
• High-Efficiency Low-Noise Power Supplies – only 12-15 W, 88-264 VAC, 47-63 Hz
• Meets FCC Class B and CE emissions requirements
• Tested for immunity to radiated and conducted RF interference
