Features

The DAC2 series is a reference-grade digital to analog converter, stereo system pre-amplifier, and
headphone amplifier with infrared remote control. It supports D/A conversion of PCM sample rates
up to 192 kHz, as well as direct DSD conversion.
HGC™ (Hybrid Gain Control) – combines motor-driven active analog potentiometer, 32-bit
digital attenuation, and passive analog attenuators, to achieve state-of-the-art performance
SABRE - 32-bit PCM D/A conversion system, four 32-bit D/A converters per channel
SABRE – Native DSD D/A conversion system, four 1-bit DSD D/A converters per channel
HPA2™ reference-grade headphone amplifier with dual outputs - "0-Ohm", high-current
(DAC2 HGC and DAC2 D model only)
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
Benchmark UltraLock2™ Jitter Attenuation System – eliminates jitter-induced distortion
Sample Rate Display – 44.1, 48, 88.2, 96, 176.4, 192 kHz and DSD
Word Length Display – 16-bit, 24-bit
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
jumpered
Aluminum IR Remote provides control of all functions
2 Stereo Analog Inputs – 2 pairs, unbalanced (RCA) (DAC2 HGC and DAC2 L model only)
3 Stereo Analog Outputs – 1 pair, balanced (XLR), plus 2 pairs unbalanced (RCA)
Low-Impedance Passive Output Pads – 0, 10, and 20 dB – optimize output level to power
amplifiers to maximize SNR
2 HPA2™ Headphone Outputs – one output has option to automatically mute main outputs
(DAC2 HGC and DAC2 D model only)
HPA2™ gain jumpers for customizing headphone output gain for headphone sensitivities (DAC2
HGC and DAC2 D model only)
12V Trigger I/O – bi-directional 12V trigger can act as input, output, or both (DAC2 HGC and
DAC2 L model only)
Home Theatre Bypass – places analog input(s) in a fixed-gain pass-through mode (DAC2
HGC and DAC2 L model only)
High Throughput Mode - places the digital input(s) in a fixed-gain
Polarity Switch – inverts the polarity of selected digital inputs
Mute and Dim Functions – accessible from remote or front panel
Automatic De-Emphasis - in response to consumer pre-emphasis bit (44.1, 48 kHz)
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, 50-60 Hz
Meets FCC Class B and CE emissions requirements
Tested for immunity to radiated and conducted RF interference
