Description

DAC3 B – REFERENCE-QUALITY – BASIC FEATURES

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 analogue inputs, the mute and polarity controls, and the headphone amplifier.

To make system integration easy, the DAC3 B retains an IR remote control (handset optional), a 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 rack-mount 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 same circuit board and the 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 ideal converter to use

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 analogue inputs, the mute and polarity controls, and the headphone amplifier.

The DAC3 B is a professional reference-grade audio digital-to-analogue converter with a fixed gain 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
