RME Unveils New DPS-2 Power Supply and LNI-2 DC Filter and Stabilizer

German audio interface specialists RME Audio, announced two new solutions designed to improve the performance of its ADI-2 series of converters in critical applications. The RME DPS-2 is a super low noise linear audio power supply with a unique µfilter and sensor technology that adds a wide range of unique and highly useful features such as offering two differently filtered outputs. The second product is the LNI-2 DC, an active DC filter with galvanic isolation.

Good news from New Jersey. Orchard Audio has updated one of its original and best-selling products, announcing the release of PecanPi DAC, Streamer, and Streamer Ultra Rev 3.0. The major update for rev 3.0 devices is the addition of a S/PDIF (coax) input, which allows the DAC to be used standalone. The rev 3.0 devices also use lower noise linear regulators and give users the option to have RCA outputs built-in. The Orchard Audio website is being updated to reflect the new models, shipping from March 2022.

Orchard Audio, the innovative audio venture created by Leo Ayzenshtat, expanded its catalog of products for audio enthusiasts and integrators with the launch of Starkrimson Ultra Amp Modules. These high performance audio power amplifier modules utilizing gallium nitride (GaN) MOSFET transistors, expand the highly praised Starkrimson amplification line and are available as completed modules or unpopulated PCBs.

In this article for audioXpress, Bill Reeve discusses “An Alternative to Linear Regulators.” A project were he searches for equivalent power-line ripple rejection with less power dissipation, using a source follower-based (SFB) low-pass filter. Because no one wants to listen to an audio amplifier that hums. This article was originally published in audioXpress, April 2014.
