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.

y 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

y SABRE - 32-bit PCM D/A conversion system, four 32-bit D/A converters per channel

y SABRE – Native DSD D/A conversion system, four 1-bit DSD D/A converters per channel

y HPA2™ reference-grade headphone amplifier with dual outputs - “0-Ohm”, high-current

(DAC2 HGC and DAC2 D model only)

y Multi-Mode Asynchronous USB Audio 2.0 – 24 bit/192 kHz, DSD (DoP 1.1)

y Driverless Asynchronous USB Audio 1.1 – 24-bit/96 kHz

y Benchmark UltraLock2™ Jitter Attenuation System – eliminates jitter-induced distortion

y Sample Rate Display – 44.1, 48, 88.2, 96, 176.4, 192 kHz and DSD

y Word Length Display – 16-bit, 24-bit

y 2 Coaxial Digital Inputs – 24-bit/192 kHz PCM, DSD (DoP 1.1)

y 2 Optical Digital Inputs – 24-bit/96 kHz PCM

y 1 Coaxial Digital Output – digital pass through from USB, Coax, and optical inputs when

jumpered

y Aluminum IR Remote provides control of all functions

y 2 Stereo Analog Inputs – 2 pairs, unbalanced (RCA) (DAC2 HGC and DAC2 L model only)

y 3 Stereo Analog Outputs – 1 pair, balanced (XLR), plus 2 pairs unbalanced (RCA)

y Low-Impedance Passive Output Pads – 0, 10, and 20 dB – optimize output level to power

amplifiers to maximize SNR

y 2 HPA2™ Headphone Outputs – one output has option to automatically mute main outputs

(DAC2 HGC and DAC2 D model only)

y HPA2™ gain jumpers for customizing headphone output gain for headphone sensitivities (DAC2

HGC and DAC2 D model only

)

y 12V Trigger I/O – bi-directional 12V trigger can act as input, output, or both (DAC2 HGC and

DAC2 L model only)

y Home Theatre Bypass – places analog input(s) in a fixed-gain pass-through mode (DAC2

HGC and DAC2 L model only)

y High Throughput Mode - places the digital input(s) in a fixed-gain

y Polarity Switch – inverts the polarity of selected digital inputs

y Mute and Dim Functions – accessible from remote or front panel

y Automatic De-Emphasis - in response to consumer pre-emphasis bit (44.1, 48 kHz)

y Power Switch - very low standby power - <0.5 W at 120 VAC

y High-Efficiency Low-Noise Power Supplies – only 12-15 W, 88-264 VAC, 50-60 Hz

y Meets FCC Class B and CE emissions requirements

y Tested for immunity to radiated and conducted RF interference
