Benchmark DAC1 2-Channel, 24-bit, 192-kHz, D-to-A Converter The DAC1 is a reference-quality, 2-channel 192-kHz 24-bit audio digital-to-analog converter featuring Benchmark’s UltraLock™ technology. The DAC1 is designed for maximum transparency and is well suited for critical playback in studio control rooms and in mastering rooms. A compact and rugged enclosure makes the DAC1 an excellent choice for location recording, broadcast facilities, and mobile trucks. The internal power supply supports all international voltages and has generous margins for over and under voltage conditions. Two ¼” headphone jacks are driven with Benchmark’s new HPA2™ headphone amplifier. The HPA2™ is a high-current amplifier that is capable of driving a wide variety of headphone loads while achieving less than 0.0003% distortion under load. The gain control sets the output level of the headphone jacks. It can also be used to control the output level of the balanced XLR and unbalanced RCA analog outputs. A rear-panel switch selects Variable or Calibrated output levels. The DAC1 will playback 192-kHz signals with a 52-kHz analog bandwidth. THD+N is an astonishing low -105 dB (0.00056%) measured at 0 dBFS, and -107 dB measured at -3 dBFS – at any playback frequency, at any sample rate, and with any degree of input jitter.

The DAC1 has an internal, international toroidal power supply. The front panel level-control always adjusts the headphone output level. The front panel level-control can also be selected to adjust the output levels at the rear of the converter. Alternately, the output levels can be set at a fixed gain with precision, rear panel; 10-turn trim pots. The balanced output level range is +10 dBu to +29 dBu at 0 dBFS.
