If you have purchased either a Benchmark HPA4 or LA4 amplifier and you currently have an older version of a DAC2 or DAC3 converter other than the DAC3 B, you may be eligible for a free DAC Firmware Upgrade Kit. Converters manufactured after 9/17/2018 are fully compatible with the HPA4 and LA4 and do not need this upgrade and do not qualify for a free upgrade kit. The date of manufacture is shown on the bottom of the unit.
Version 2.2 improves the power management and provides a very slight reduction in standby power consumption. Standby power consumption is reduced from 0.50 Watts to 0.28 Watts.
Note: The DAC3 B Firmware Version 1.1 is equivalent to Version 2.2 of the HGC and L.
Versions starting with 2.0 include the preamplifier COMPATIBILITY mode. This mode disables the MUTE and DIM functions and places the volume control in the unity-gain HT position. Use this mode when the volume is being controlled by a downstream line amplifier such as the Benchmark HPA4.
When paired with an HPA4, the DAC3 and HPA4 can be controlled by a single Benchmark IR remote control. The HPA4 provides volume control, DIM and MUTE functions. Both units switch inputs in a coordinated fashion so that all digital and analog inputs are available. Place the DAC3 in compatibility mode and connect it to XLR input 1 on the HPA4. Select "Benchmark DAC on XLR1" in the HPA4 REMOTE menu.
If you are located in a country served by our distributor network, you may not be able to order directly from our store. If the checkout option is not available, you will need to call or email our customer service department to order your kit.
The DAC3 circuit boards and the software chip can be damaged by static electricity. Use of an ESD wrist strap is recommended. If a wrist strap is not available, hold chassis with one hand while inserting chip and moving jumpers. Do not touch the circuit board until your other hand is making contact with the chassis.
The software chip will be damaged if it is inserted backwards. The white line must face the rear panel of the DAC3!

"Having bought an HPA4 preamp to pair with my existing DAC3 and AHB2 I required a firmware upgrade for the DAC3. I requested it online and it was mailed to the UK quickly. The installation was clearly documented and straightforward. Yet again, I'm impressed with the quality of Benchmark products and their service."
"I am an obessive audiophile. I have Bluesound Node N130, powered by a Teddy Pardo PS connected to my Benchmark DAC3 via a Audio Sensibility Statement coxial cable. I previously installed Synergistic Research ORANGE Quantum Fuses in my DAC3, which made a significant improvement. After installing the Firmware Upgrade Kit I heard a noticable improvement in detail and soundstage depth. Here's the golden rule: Jitter and noise in the digital realm equals distortion in the analogue realm."
"Great service. Fast shipping. Product was well packed, and userguide for implementing the firmware update was easy to follow."
The AHB2 sets the benchmark for the lowest noise and lowest distortion in a power amplifier ... at any price.
Benchmark preamplifiers are designed to accept and deliver studio-level balanced output signals, but they also deliver state-of-the-art performance when operating at HiFi signal levels which are typically 10 dB lower.
High-Resolution Playback Begins with an External D/A Converter
Benchmark Studio&Stage™ professional audio cables deliver the high performance required for studio applications while delivering the durability to withstand the most demanding live sound applications.
