COWON PS 128GB - silver

A completely new level

dominion over all

The Plenum

Native support DSD256 | 24bit / 192kHz high-resolution audio | high performance Burr-Brown DAC PCM1792A | 120 db SNR, THD + N of 0.0005%, crosstalk -139 db | 3Vrms strong output | extra precision dual oscillator TXCO | high quality balanced output | JetEffect and BBE + 7 | DXD / DSD (DFF, DSF) / FLAC / WAV / AIFF / ALAC / APE / MP3 / WMA / OGG / WV / TTA / DCF | dual-core ARM Cortex A9 | 3.7 "AMOLED display with 16.7 million colors | piece, extra solid metal body | isometric design edges | convenient multifunction button | built-in high-speed memory 128 gigabytes | card slot for micro SDXC | optical output | Support expansion units | Matrix Viewer | Stereo level meter | features an external USB converter for PC

Pure essence of perfection

The plenum played without converting the format most advanced DSD 256 (11.2 MHz) and DXD (352.8 / 384 kHz) utilizes genuine HiFi Burr-Brown PCM1792A, contains high-quality output and perfectly balanced dual precision TCXO oscillators and strong output 3 Vrms can handle any headphones. The result is an entirely new listening experience, individual instruments come alive with breathtaking dynamics and suddenly you will be transported into a concert hall with every listen.

Direct support to the DSD DSD 256

As one of the few able plenum directly with DSD playback without conversion to PCM. Copes with DSD 256 (1 bit, 11.2 MHz), 64 DSD and DSD 128 DSD (Direct Stream Digital) format is a high quality Super Audio CD, which processes signals with extreme delicacy on the bit. This technology provides maximum possible information about the audio reproduction of the finest sound details. Because it is a model for the true audiophile who can use this highest studio quality to appreciate.

The swift response of the amplifier 3Vrms

For optimal response time must the amplifier actually bring true sound to headphones. 20 years of development of innovative technologies for audio devices allow engineers from the company COWON produce audio output with high output voltage while maintaining the highest standards of linearity. Enjoy stunning performance from the finest high-impedance headphones HiFi, without the hassle of connecting a bulky dedicated amplifier.

Metal body with isometric edges

Every millimeter copper isometric head was shaped precisely to highlight intersecting region. Circular metal power button has been cleverly positioned to the lower levels, so minimize its unwanted compression. Additionally, he was awarded the design of the device interesting detail.

Knurled 3D backside embodies a design that corresponds with a rich three-dimensional reproduction and soft lighting LED key elements. The overall processing simply can not have a reservation - piece aluminum body has been completed through CNC machining and diamond cutting.

Stable performance dual oscillator

Using a dual oscillator 44.1 / 48 kHz TCXO (Temperature Compensated Crystal Oscillator), each of the sounds sampling of 44.1 kHz and 48 kHz exactly produced with minimal variation due to temperature control and power differences. The plenum why exactly reproduces high quality sound.

Peak balanced symmetrical output

Balanced balanced output effectively block the noise that is generated during the transmission signal by adding rozfázovaných unbalanced signals. Because it transmits two types of signals at once, it can plenum S amplify and correct the output signal for clearer reproduction of the original sound.

The creator of the perfect sound

If you want a true high definition sound, the plenum with the best choice. In its category presents an unbeatable combination of high signal to noise ratio (120 dB), imperceptible harmonic distortion (0.0005%) and extremely low crosstalk (-139 db). Given that it is acoustically the most important criteria, you should be when selecting always remember.

SNR (120 dB)

SNR (120 dB)

Signal to noise ratio (SNR), indicates how much noise is admixed to the pure audio signal. High SNR indicates a cleaner, free of noise studio quality sound.

Duální TXCO

dual TXCO

Extremely high precision dual clock oscillator guarantees perfect compliance with sampling rates of 44.1 kHz and 48 kHz.

THD+N (0,0005 %)

THD + N (0.0005%)

Total harmonic distortion and noise (THD + N) is an indicator signal distortion, caused by diverse factors, including harmonics. A small value indicates a low occurrence of distortion in the source and therefore sound quality.

Stereo přeslech (-139 dB)

Stereo crosstalk (-139 db)

Stereo crosstalk (crosstalk) indicates the degree of interference between left and right channels, caused by electromagnetic induction. A low value means less interference for a clear separation between left and right channels.

High signal / noise ratio - guarantee the highest quality of sound

When listening to music can record the signal in the noise, which is an integral part of each recording. This noise then penetrates the entire reproductive way to the exit. The volume of the signal to noise is called SNR (Signal to Noise Ratio - signal / noise). SNR compares the level of the desired signal to the level of background noise. SNR is one of the key criteria that can be measured and can be compared with others.

If the difference between the two devices 6dB then it is quantized difference of 1 bit digital signal. For example, the device has 113 db SNR loss of more than one of the quantum bit in the digital signal, which has the effect of doubling the difference resolution sound wave compared to plenum S 120 dB. Therefore, to enjoy HD audio device must have the highest SNR value.

If your device has a lower SNR and THD, it means that its performance is distorted when reproducing 24 and 16-bit sources. COWON devoted considerable time, effort and resources to get the best values ??of SNR, THD, etc., Plenum S is therefore the most suitable candidate for all who want to enjoy the full quality of HD sound.

JetEffect 7 - another criterion for great sound

Combining Functions 7 JetEffect and BBE + is used to correct a phase distortion caused by the physical limitations of the receiver or listening environment. Thanks to the reproduced sound close to the original studio recording. In addition, you will also have a sound tuning tool according to your specific preferences. Easily proceeding with 50 presets and reference 10pásmovému equalizer correction phase for setting the audio. No matter what environment while listening to move, you always get the highest possible quality.

10-band EQ filters

Advanced features to customize the frequency and width of each band.


Effects of high-resolution audio for sharpening.


Bass booster to highlight the extra low frequencies.

3D Surround

Three-dimensional sound for enhanced sense of space.

MP Enhance

Restores harmony that were lost lossy compression.

Reverb (8 presets)

Various effects reverb for enhanced realism.

Chorus (9 presets)

Interesting effects that enrich the final recitation.

Pummeling HW and SW clever

Computing power caters powerful dual-core Cortex A9 processor at a frequency of 1.2 GHz. Thanks to him and start running Linux installed quickly and smoothly. For data intensive files, 24bit PCM, DSD and DXD is also needed sufficient storage capacity, the forms fast eMMC memory of 128 gigabytes. If needed, but it can easily be expanded with micro SDXC card slot.

Player also includes several audio ports, based on a classic course 3.5 mm output, which complements but still its balanced flavor and a 4-pin optical output, through which the player can easily connect to an external decoder or your home HiFi report.

140 volume levels

The plenum allows you to adjust the volume of the 140 levels. If you hold down the button to change the volume, the volume changes rapidly. If you just press the button, then each step will change the volume by 0.5 dB. Adjusting the volume can not be more precise.


Sound card in your computer generates noise and parasitic noise. No problem for the plenum S - connection to a PC is made via USB. Thanks to him, the player can be used as a top external sound card that is connected to your computer. When playing audio files on the computer's plenum S is converted into the highest possible quality. This allows you to enjoy HD audio without having to copy files to the device.

Intuitive GUI and 3.7 "AMOLED touchscreen

3.7 "touchscreen AMOLED shining with colors and guarantees trouble-free readability from any angle. The intuitive graphical user interface (GUI) makes operation then up playing. There are many different designs interface, matrix browser and stereo volume level meter. The names of songs, artists or mentioned lyrics are displayed on the screen through advanced formats LRC, LDB, Lyrics3 and ID3 Tag lyrics. There is also support diverse playlists available to them but also by the smart search, which will simplify the start of the desired track.
