Introduction

ARIOSO

D/A converter, preamplifier and headphones amplifier.

In conjunction with a laptop / PC operating © Vista / Windows7 /

ARIOSO realizes a high performance audio source without drawbacks. The playback of audio files at CD quality (1411 kbps) is absolutely comparable with the reproduction of a pure high class CD-player. The result you get

ARIOSO you play and on the correct settings of your computer running the audio software. In contrast to a red book CD-player, a computer in conjunction with the USB input can play files with extremely high resolution and with different formats like WAV, FLAC or DFF (DSD bitstream) bitstream) internet shops like 2L.no, HDtracks.com or highresaudio.com to name but a few. The choice of music and the number of albums available is clearly limited today, but new releases show up every day. The big advantage here is that you are not bound to a certain format like SACD or DVD-Audio. Computer audio is future proof.

The second essential digital audio format is S/PDIF (Coax / Toslink).

ARIOSO supports sample rates up to 192kHz and bit depths up to 24bit. The S/PDIF inputs are intended for high performance CD drives as well as for © iphone / ipad / ipod docking stations. Here it builds the bridge to the playback of music collections stored on mobile devices.

Connections - rear

AC mains: connect a high quality IEC power cable to the power socket. Before connecting the cable to a live wall socket, ensure that it is firmly connected to the unit’s power socket first.

Power (on/off) switch: the on/off switch disconnects the unit completely from the AC mains when switched off. No standby function is used.

USB – input: the USB input employs a standard female B USB connector. Connect to the host computer with a high quality 2.0 USB cable.

Coax – input: an RCA connector is provided for correct hook-up of coaxial cables.

Toslink – input: the optical input is compliant with JEITA RC-5720B standard, better known as Toslink. A shutter is provided to protect the sensitive optical receiver from dust.

Analogue Left / Right – output: a pair of gold plated RCA’s allows the connection of a power amplifier. This high current output drives any amplifier with ease.

Operation

ARIOSO ready to operate. The blue LED confirms the power on status. It takes approximately 60s (1mi n) before the DAC is ready to operate. stand by function is implemented. Power off means zero current drain from the mains.

The front toggle switch is used to select the input source. The USB input conforms to the USB audio 2.0 standard. Here, a computer running Windows, Linux or a Mac is connected via a high quality cable (length < 1.5m). The yellow LED lights up, when the USB input is selected and when bus power is present (cable connected, computer powered up). This LED alters the colour to green when a

DSD stream is detected. Using and listening to the USB input requires a Mac or Windows computer with the appropriate driver installed.

S/PDIF sources like a CD-transport or an i-pod docking station are conveniently connected to the RCA connector, whereas the Toslink input is used for sources requiring an interference free link. A TV set top box for instance is best connected here using a digital fibre optic cable.

The volume control works simultaneously for both analogue outputs. The control range spans from -80 … +7dB.

Driver installation

Installing process (Mac)

No drivers are required for the Mac computer with OSX 10.6.4 and later. A native support for audio devices compliant with USB 2.0

Audio class is already included in the operating system. Your

ARIOSO use. Be sure to select the ARIOSO output device in the “System Preferences / (Hardware) Sound /

Output” menu. In the “Applications / Utilities / Audio Midi setup.app” menu you can select the standard sample rate which is (44100 kHz) for CD sourced music. Using high end audio player software instead of iTunes is recommended.

Installation process (PC)

Do not connect the ARIOSO and install the driver:

ARIOSO http://linnenberg-audio.de/html/downloads.html

The installation package offers two installation utilities, “setup32.exe” and “setup64.exe” for Vista / Win7 or XP operating systems. Doubleclick on either “setup64.exe” or “setup32.exe”, depending on your operating system: the driver will be installed in your PC. Restart your

PC or Notebook and connect the ARIOSO

ARIOSO will now be recognized as usable device.

When the driver installation is done, you are ready to play music via

USB. As long as the ARIOSO as output device. As it is the case with Mac computer, we highly recommend using special software instead of the Windows Media

Player.

JPLAY (PC)

There are numerous high performance audio player for Mac and

Windows OS available. Describing all of them would definitely go beyond the scope of this manual. If you should encounter problems with specific software, please feel free to send an enquiry regarding the matter. We will be happy in assisting you rectifying the subject.

Representative for a high quality audio player the JPLAY software is presented below. The reason why JPLAY was chosen is simple: it sounds awesome and is easy to use – even for computer newbie’s.

order your software licence at www.jplay.eu

. One drawback is the very basic to non existent user interface, the other is that JPLAY can produce clicks and plops when in DSD mode (start.- and endpoint)

Those of you not willing to except the limited functionality can use

JPLAY as ASIO output device in foobar2000 or just work with foobar2000 alone. Foobar2000 is free of charge, but needs to be accustomed for DSD playback capability. Here is what to do:

7

Foobar2000 (PC for PCM and DSD playback):

Install the latest version of foobar2000 from the official website www.foobar2000.org

. Download the kernel streaming support from the components section of the website. This allows you to have a bit-perfect transfer via USB. Decompress the file and copy the file

“foo_out_ks.dll” in the directory “components” of the foobar2000 directory.

After having successfully installed all foobar2000 components,

ARIOSO

Click on “file”; a drop down menu will appear; here go to

“preferences”. Select “playback / output”. Now you have to make several adjustments:

Device: KS: Ivo Linnenberg Elektronik Streaming

Buffer length: 2000ms

Output format: 24bit

That’s the default setting for PCM files like WAV, FLAC or even MP3. In

ARIOSO following: First, you need to download and install the Super Audio

CD Decoder plug‐in at: www.sourceforge.net/projects/sacddecoder/files/foo_input_sacd/

Download “foo_input_sacd‐0.6.1.zip” (or later), open and extract all files. Then click and install “ASIOProxyInstall‐0.6.0.exe”. After the installation is finished, copy the “foo_input_sacd.dll” file into the foobar2000 components folder. Next download and install the ASIO support 2.1.2 (or later version) plug‐in: www.foobar2000.org/components/view/foo_out_asio/

Run the downloaded file foo_out_asio.fb2k‐component to install the ASIO plug‐in. Start foobar2000, click menu and select “file”, and then enter the “preference” section. Jump to “playback / output” tab. Select “ASIO: foo_dsd_asio” as output device in the “Device” section.

Go to the ASIO4ALL website and download “ASIO4ALL 2.10” (or newer): www.ASIO4ALL.com

In foobar2000 “preferences / playback / output / ASIO” you will see

ASIO4ALL as an ASIO driver option: Double click on ASIO4ALL to launch the control panel. If you don’t see the control panel it is minimized on your task bar. Configure ASIO4ALL by selecting “Ivo

Linnenberg Elektronik USB driver 1.0.56”. Click on the little icon to highlight it.

Now configure “foo_dsd_asio” by selecting ASIO4ALL as the ASIO driver. Here again, the control panel may be minimized on the task bar. Important: Use “DoP Marker 0x05/0xFA” = “DSD Playback

Method” ; “PCM to DSD Method” = “none”; “Fs” = “DSD64”

Close the “foo_dsd_asio” pop‐up window; go back to the “Tools /

SACD” tab and select “DSD” as “ASIO Driver Mode” option.

Furthermore: “PCM-Volume” = “+0dB”; “PCM Samplerate” =

“176000”; “DSDtoPCM Mode” = “Multistage”; “Preferable Area” =

“Stereo”

Click “OK” button on Preferences windows and restart the program.

You are now ready to play back PCM and DSD files with foobar2000.

Some tips and hints using DSD

Following the instruction steps above will guarantee a trouble free operation. When using the DSD feature, please consider this additional advice:

The DSD bit stream is transmitted using the PCM structure. The so called DoP marker indicates that the incoming data is actually DSD and not PCM. The ARIOSO selects the proper signal routing automatically by analysing the data stream. When in DSD mode, the digital signal directly drives the sigma delta modulator of the

DAC chip. No buffering, resampling, filtering or soft muting takes place: the DSD stream reaches the analogue output in the purest native form. In contrast to the fool proof PCM format, abrupt signal changes will be transmitted to the analogue output without attenuation. This implies some easy to follow rules:

In order to avoid click noise, avoid skipping in DSD files and avoid mixed DSD64 / DSD128 playli sts. It is good practice to have separate playlists for DSD64, DSD128 and PCM. The different PCM separate playlists for DSD64, DSD128 and PCM. The different PCM tracks can vary from 44.1kHz/16bit to 192kHz/32bit wi thout producing any click noise, whereas switching back and forth between DSD64 and DSD128 may produce som thout between DSD64 and DSD128 may produce som e harmless artefacts.

Generally, the DAC behaviour is largely dependent on the music player software used, because the software is responsible for maintaining the DoP marker.
