    The MacOS version compatibility / Internet transaction security dilemma

    Channel D

    Ever since we began developing and marketing software products over 21 years ago, we've always endeavored to support as wide a range of legacy computer operating system (OS) versions and computers as technically possible. Due to extensive optimization for low CPU usage, our products can still be used on 12 year old computers running a 10 year old operating system (Mac OS X 10.5, first released in 2007)!

    However, Internet commerce sites (including the merchant service that processes our transactions) are migrating their systems to something called TLS 1.2 ("Transport Layer Security," previously called SSL) due to Internet hacking and security concerns. Unfortunately, this technology is not backward compatible with older OS versions - or at least, old OS versions aren't being updated to support it.

    So, while you may be able to use our products with computers running old OS versions, starting recently you cannot easily purchase them via the Internet with a web browser running under an old OS.

    To reiterate:

  • Our software products are compatible with computers running Mac OS versions up to 10 years old.
  • However, beginning recently (April 2017) you cannot purchase our products using computers running 10 year old Mac OS versions. (There is a work-around, however.*)

  • This presents an unpleasant dilemma. Due to these circumstances which are beyond our control requiring supporting increasingly restrictive (but nonetheless necessary) Internet security policies, for future product releases we will likely be discontinuing support for older OS versions.

    As of April 2017, the oldest Mac OS version that supports current Internet transaction security policy is 10.9 ("Mavericks"). Our products (that is, the software license codes) are delivered using email, so they also can be purchased with web browsers running under updated versions of Windows or Linux, as well as on portable devices running iOS, Android, etc. Apple computers supporting MacOS 10.9 are mid 2007 or later iMacs or 15 and 17 inch MacBook Pros; 2008 or later Mac Pro and MacBooks, and mid 2009 or later Mac Minis and 13 inch MacBook Pros.

    *Mozilla Firefox 45.9.4 "Extended Support Release" (esr) supports TLS 1.2, runs on MacOS 10.6 through 10.8 and can be used to purchase products from our web store. It can be downloaded here. Click on the link, then be sure to click on Show Firefox 45, and finally download the appropriate language-localized version.

    Seta L20 introduced at AXPONA 2017

    At AXPONA 2017, we introduced our brand new Seta® L20 moving coil phono preamplifier.

    Several years in development, the L20 represents a cost-no-object statement product that builds on the strengths of our award winning Seta Model L MC phono preamplifier by increasing the frequency bandwidth to 20 megahertz (20,000,000 Hz) – 1000 times the bandwidth of audible frequencies - while simultaneously and dramatically increasing the signal to noise ratio and reducing harmonic and intermodulation distortion to nearly unmeasurable levels.

    The Seta L20ʼs lower noise and ultra-low harmonic and intermodulation distortion and ultra wide signal bandwidth pays clear and discernible dividends by delivering breathtaking clarity, depth and accuracy from LPs.

    The L20 is a ground breaking phono preamplifier in significant ways.

    Channel D

    A dual-mono, direct coupled, fully balanced design, each channel has its own independent rechargeable battery power supply. Though the left and right channels share the chassis, they are galvanically isolated from each other and from the outside world. Chassis common is floating but can be tied to either or both channels.

    The equivalent input noise of the L20, measured with a 1 ohm source resistance, is an astonishingly low -134 dBu, despite the extreme signal bandwidth capability.

    The L20ʼs 24 volt power supply rails are able to swing 20 volts peak to peak into a 600 ohm load from DC to 100 kilohertz with negligible distortion. The L20 includes selectable voltage and current amplification modes as well as front panel adjustable gain and Mono summing mode, plus the Setaʼs unique cartridge balance trim control, accessible via the front panel.

    The L20 weighs 45 pounds and includes a 576 watt-hour internal rechargeable battery power supply. Battery recharging is automatically managed via proprietary Channel D circuitry, the same as used in the Model L and all other Channel D Seta preamplifiers. Pricing to be announced, but will be substantially higher than other preamplifiers in our product line.

    More details to follow.

    Channel D at Capital Audiofest 2016

    Our exhibit room audio system was the same high performance, tri-amped (panels/stereo woofers/stereo subwoofers) system we used at AXPONA (see April 2016 News post below for details).

    Taming the acoustics of this nearly-square room footprint with its unfavorable dimensional ratio (42 by 46 by 11 feet) was extremely challenging. Aided by making careful acoustic measurements with Channel D's Mac the Scope software in swept-sine and third-octave-filtered pink noise modes, we spent over 8 hours determining optimal positions for the panels and woofers, before fine-tuning and voicing the system with music.

    Using the adjustable time alignment feature of the Pure Music / Pure Vinyl crossover gave us the freedom to position the woofers for best uniformity of coverage (especially important in an exhibit room), slam / definition and frequency response, and to position the panels for best imaging. The bandwidth-limited (250 Hz and up) audio used to drive the panels was delayed 7.2 milliseconds relative to the main woofers, and the aggregate panel/woofer combination was delayed an additional 16.7 milliseconds relative to the subwoofers. Time alignment for speaker positioning flexibility is impossible to realize in an all-analog multi-amped system because the necessary signal delays cannot be generated with analog circuitry.

    See you at Capital Audiofest next year!

    Analog Planet

    Our exhibit room system consisted of:
    - Channel D Pure Music and Pure Vinyl software ($129 / $299)
    - Mac Mini (controlled using Screen Sharing and a MacBook Air) ($799)
    - Apple Cinema Display with TrollTouch resistive touchscreen overlay
    - Music Hall MMF 9.3 turntable ($2200), Ortofon Cadenza Bronze cartridge ($2300)
    - Channel D Seta Model L Phono Preamplifier ($3800)
    - Lynx Hilo ADC / DAC ($2500)
    - Music Storage: Synology DS-513 RAID 6 NAS 9 TB ($1700)
    - Wall panels and corner bass traps from ATS (ca. $1200 total)
    - Wisdom Audio D75 Adrenaline Planar Magnetic Loudspeakers (discontinued; ca. $28,000 in 1995)

    We omitted the analog 2-way electronic crossover of the Wisdom speakers (what we feel is their Achilles heel) and implemented the crossover using the built-in crossover feature in Pure Music / Pure Vinyl, in conjunction with 6 output channels from the Lynx Hilo DAC. This improved definition and removed the slight haze caused by the analog electronics and its multiple and complex op-amp based filters. The system was tri-amped with a Hegel H20 power amplifier ($6000, 200 watts per channel) driving the panels and digital power amplifiers supplying 2000 watts per channel driving the bass and sub bass speakers (all located behind the backdrop). The bass was time-aligned to the panels using the digital delay feature in the Pure Music / Pure Vinyl crossover. Therefore, the bass speakers could be positioned for best tonal uniformity and coverage, while the panels could be positioned for best imaging. (Those locations are almost never the same.) More than one group of attendees remarked something along the lines of "you realize that you are embarrassing the big guys?"

    Enjoy the Music's review of our Seta Piccola phono preamplifier: "Much more than a great phono preamp"

    Channel D

    "Its greatest asset is its transparency, so transparent that when listening to records I forgot it was in my system. That's the nicest thing that I can say about a component where its main purpose is to boost the signal from a phono cartridge. That it does so with causing as little harm as possible is not as easy as one might think. The Seta Piccola Mk2 manages to do this, and at the same time gets out of the way of the signal it is processing. I highly recommend the Seta Piccola Mk.2 for anyone looking for a phono preamp anywhere near its price." Click for full review

    Channel D Exhibit, Room 490

    After many years of being congratulated for having a "good sounding room" (putatively because of having "good sounding speakers") we decided to prove that there is more that goes into getting good sound than the speakers. The room setup, treatments (from ATS Acoustics) and playback front-end are paramount. Provided that all of those are optimal, then the sound quality will shine through, regarless of the speakers which are used (provided there is a certain minimum level of quality there). So we took a step back to 2009/2010 and used the same speakers we did at RMAF and AXPONA: Polk RTI-A1 bookshelf speakers, which cost less than $300 per pair new at Amazon. We covered the markings on the speakers, so that "brand bias" did not enter into the picture. Judging by the reactions from press (see Audiostream coverage linked below) and attendees, we were successful. :-)

    $1598 Channel D Lino Phono Preamp / ADC surpasses $4500 Audio Converter

    "22nd of September 2015. My Lino Phono Preamp/192/24 ADC-DAC arrived yesterday. Disconnected my Prism Sound Orpheus and the Lino was plugged in to my system of Mac Mini, VPI Classic (balanced output) and low output ZYX R1000 Airy 3 MC cartridge. Some adjustment had to be done: load, gain and some other things but basically plug and play.

    "And what a relief. Now everything became quiet, much less system (almost dead quiet) and surface noise. Soundstage increased and a more coherent sound appeared with no loss of resolution compared to the Prism. And this was straight from the box.

    "When you hear this you can tell the Lino is made for vinyl. Prism Orpheus is a great sounding Sound Card even with vinyl but the Lino made a huge difference."

    Pure Music 2.0.3 Update Released

    Channel D

    The 2.0.3 Update addresses performance issues with iTunes 12.1, an Unexpected Quit issue with Playthrough / Streamthrough, enhancements to Streamthrough, as well as including additional bug fixes and performance enhancements, and is recommended for all users.

    Pure Music 2.0.3, available for download now from the Channel D website, brings enhancements to its Streamthrough streaming audio technology. Streamthrough permits conveniently playing and enhancing other computer audio sources through Pure Music, with full access to Pure Music's dithered volume control, 64 bit crossover, audio EQ plug-ins, NetSend streaming, metering, etc., all without needing to quit Pure Music.

    Streamthrough has been included with Pure Music for the last 4 years (making Pure Music the first computer audio software to offer this feature, by a considerable margin). However, Streamthrough has been enhanced and refined even further in Pure Music 2.0.3, making it the most advanced and automated such offering available.

    Streamthrough is fully integrated with Pure Music. There is no need to purchase or launch a separate application! Even better, switching to Streamthrough is AUTOMATIC - if you play an Internet radio station in iTunes, or TIDAL, Qobuz, Spotify, YouTube, etc., the audio is "automagically" detected and switches Pure Music from file play to Streamthrough mode!

    In addition, Pure Music 2.0.3 includes improvements to address performance issues with iTunes 12.1, which was recently released by Apple.

    "It's now been quite a few months, and it has not only met my expectations, but exceeded them... For most of my years in the-end audio, I was a "purist." I believed that systems had to be as simple as possible, that only SET amps could provide musical satisfaction, and that CDs were at best, a poor substitute for vinyl. As time has gone by, and as I've experienced new things, I've had to shed many pre-conceived notions, and spit out quite a bit of Kool-Aid. The use of digital processing, not just for room correction but also - heaven forbid-! - for RIAA processing, has been the latest and perhaps most significant step."

    Best Sound (Cost no Object) - AXPONA 2014

    Channel D

    Best Sound Award (Cost no Object) - "Best sound award goes to the Channel D/Lynx Hilo/Hegel/Joseph Audio Pulsar system in the "Wabash" room. Using room correction, corner bass traps and sidewall absorbers from ATS, and precise speaker placement, Channel D was one of the few rooms to get accurate sound." Click for Show Report.

    AXPONA 2014 - System Setup Details

    2-way bi-amped subwoofer using Pure Music's Pure Vinyl's adjustable crossover A bi-amped stereo subwoofer setup was needed to attain lifelike listening levels with bookshelf speakers in the large (16x27x10 foot) room. Accordingly, we used the built-in 64-bit adjustable crossover feature of the Pure Music/Pure Vinyl software. Room correction consisted only of bass absorber traps and wall panels from ATS Acoustics, in conjunction with painstaking optimization of the positions - to within less than an inch - of subwoofers and main speakers (aided by Channel D's Mac the Scope measurement software). The crossover used four analog outputs from the Lynx Hilo DAC: two for the Pulsar bookshelf speakers and two for the subs. A second stereo amplifier was used to drive the subs.

    The subs, which were positioned along the back wall behind the banner, also were time-aligned by delaying the main speakers 2.95 milliseconds using the time alignment feature of Pure Music/Pure Vinyl. Time alignment is a critical but often overlooked aspect of integrating subwoofers into an audio system and is needed to insure that the sounds from the subs and the main speakers arrive at the listening position(s) simultaneously, essential for optimum smoothness, "slam," and definition.

    Pure Music Update Released

    The latest free Pure Music update, version 1.88, has been posted. We have decided to postpone the 1.9 release for additional testing of new features which are not included in 1.88, which was the version frozen at the time Pure Vinyl 3.1 was completed (and was incorporated in Pure Vinyl 3.1).

    In the interim, Pure Music 1.88 has more than two dozen new features and performance enhancements compared to Pure Music 1.86. A complete list of changes is provided in the Release Notes in the User's Guide included with the update. Additional, significant user-requested feature enhancements are coming in Pure Music 1.9, which we anticipate will be available by mid - December.

    Hurricane Sandy Update (Pure Vinyl 3.1 released)

    Our utility power was finally restored late Monday afternoon, November 12 (after operating for two weeks on emergency generator power) but our Internet and phone were interrupted because the utility crew cut the fiber optic line while installing four new utility poles on our drop. Finally, everything was restored late Tuesday afternoon, November 13. The new Pure Vinyl 3.1 update was posted on November 16. The Pure Music 1.9 update will be posted one week after that. We would prefer to release them simultaneously, but the staging is necessary to manage the higher than normal load on our server which occurs every time we post a new release. The new releases will be free, as usual. - Channel D Support Team

    Special Advisory Statement - Hurricane Sandy

    October 30, 2012 - To our loyal Customers: Our operations have been disrupted by the destructive Hurricane Sandy, the worst storm to hit the Mid-Atlantic States in 50 years. We currently are working using sporadically available and limited reliability emergency generator power, and it may be several days to a week before power and normal operations are restored. We are postponing the release of the updates of Pure Vinyl and Pure Music because we will be unable to deliver our usual level of support at this time, and anticipate that the new releases will likely generate their share of questions. Our merchant operations are based in the San Francisco area, and continue to operate normally. We thank you for your patience and understanding at this difficult time, while we cope with the aftermath of the storm. - Channel D Support Team

    RMAF 2012: Channel D Introduces New Ultra Wide Bandwidth Seta Plus Phono Preamplifier and Seta DAC Buffer Products

    Channel D

    Channel D 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.


    Channel D

    - 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.

    For full information, please see the news release.
