Channel D Introduces New Phono Preamplifier and DAC Buffer Products

Channel D, developers of the innovative Pure Vinyl™ and Pure Music® audio software for Apple Macintosh computers and the creator of the Seta® Ultra Wide Bandwidth Balanced Flat Phono Preamplifier will introduce their new Seta Plus Phono Preamplifer and Seta DAC Buffer products at the 2012 Rocky Mountain Audio Fest, October 12-14, in Exhibit Room 482.

- The new Seta Plus Phono Preamplifier represents the continued evolution of Channel D’s ground-breaking ultra wide bandwidth Seta “flat” phono preamplifier. The Seta Plus includes an updated, ultra low impedance, low noise rechargeable internal AGM battery power supply based on the original Seta phono preamplifier design, delivering superb transparency, detail and three-dimensionality for vinyl playback, a key benefit of the Seta’s ultra wide bandwidth battery powered design. An optional high quality headphone output is available.

- The new Seta DAC Buffer solves a critical problem with today’s Computer Audio that occurs when driving power amplifiers directly with the output of a DAC: setting the proper system gain structure. The Seta DAC Buffer provides a sonically transparent, analog way of adjusting the attenuation of any DAC’s output (in 6 dB steps from -6 to -30 dB), permitting using the DAC or computer playback software’s digital volume control in its optimum sweet spot (-10 to 0 dBFS).

Unlike passive signal attenuators which would be used for a similar purpose, the high (2 megohm) input impedance of the DAC Buffer insures that electronic loading of the DAC’s output is kept to a minimum, while providing a sonically transparent, ultra wide bandwidth (DC - 12 MHz, -3 dB) and low (20 ohms) output impedance for driving any power amplifier load or long interconnect run without adding noise or distortion. The net effect is one of stunningly deeper, more well controlled bass with greater impact plus lower listening fatigue and improved ease of presentation over the entire audio frequency range.
