Synthax and RME Announce Major Firmware Update for the ADI-2 Pro

Enhanced functionality and more intuitive operation are key attributes of latest update

Ft. Lauderdale, FL – May 2017… Synthax, Inc., the Americas distributor for RME, a leading manufacturer of high quality digital audio solutions, is pleased to announce the availability of a major new update for the RME ADI-2 Pro High-end AD/DA converter. In addition to correcting a least significant bit error in the input channel 2 (analog right) and an invalid mixer parameter, the new update extends the ADI-2 Pro’s functionality considerably.

Among the numerous system enhancements, RME has performed DSP code optimization: rewriting and restructuring parts of the DSP code to lower system resource usage. This enabled RME’s engineering team to activate the full frequency range for the third EQ band, which can now operate down to 20 Hz. Similarly, there has been a major overhaul of Channel 1 and 2 Handling by separating settings memories for Main Output 1/2 and Phones Output 1/2. There are now individual settings for both sets of outputs.

With this update, the rear outputs now also ramp up the volume when either switching between front and back manually or when removing a phones plug. Further, before switching an output into the Off state, volume is temporarily reduced because the quick mute by the relay often resembles a click sound, which does not happen at lower volumes. With this update, RME has optimized the digital volume control to preserve a full 190 dB distortion-free resolution at the digital outputs.

The updated firmware also provides LCD Tint control. Now, the IPS panels used in the ADI-2 Pro come in a wide range of colors, from bluish white up to a faded yellow. Likewise, there are numerous improvements to the Graphical User Interface (GUI) and several new functions, including Bass/Treble Enable On/Off, the ability to toggle between the Phones and Rear outputs by pushing the Volume button for half a second, and changing the digital output’s source so they get their signal from the Mains Out 1/2. Additionally, there is now dedicated Mute capability via a Mute entry in the I/O menu of outputs 1/2 and 3/4, re-mapped function keys for improved efficiency, plus a Bit Test to ensure full bit accuracy when working in the digital domain.

Mathias von Heydekampf, Managing Director at Synthax, commented on the new ADI-2 Pro firmware update, “Since its introduction, the ADI-2 Pro has delivered crystal clear, sonic transparency for use in a wide range of audio applications. With the new Firmware Update 141 / DSP 76, this exceptional AD/DA converter takes yet another dramatic step forward. I have every confidence that users – both current and prospective – will find much to like.”
