· Lossless LEEDH Processing volume control
· “bit-perfect” data path from its RJ45 input to its AES/EBU and S/PDIF outputs
· Innovative and highly performing clock circuit and synchronization system
· Ultra-low phase noise oscillators, < -135dBc/SQ(Hz) at 100Hz and < 50fs RMS jitter
Emerson Series Product Highlights
Technology, precision & quality
The original format of the digital Hi-Res music tracks provided by streaming services must be maintained.
With this in mind, we perform no alterations or conversions in order to fully respect data integrity. The streamed music is fully "bit-perfect" all the way through.
We have added extremely precise clocks which ensure perfect timing of data flow, "jitter-free" from the network playback through to the output signals.
Emotional Instruments of Precision
With no unnecessary features, no compromise on quality and the ease of use that contributed to the reputation of Wattson Audio products, the Emerson Series invites you to spend many hours in its musical world.
Emerson DIGITAL always within Reach
In addition to the multi-function front panel button, the Wattson Music app for IOS and the Wattson Remote app for Android handle all the settings on your Emerson DIGITAL, from the bass EQ to the various interactions with the volume of the device.
You'll also find the entire Hi-Res catalog of TIDAL and Qobuz services, as well as the many radio stations offered by Airable in the Wattson Music app.
Complex and Versatile
The Wattson on-board digital signal processors are extremely advanced, featuring our new proprietary oversampling algorithm.
From LEEDH Processing digital volume control, to calculation of low-frequency correction filters and DSD to PCM conversion, this DSP is a key element in the design and operation of the Madison.
Inside the Technology
The apparent simplicity of our streamers actually hides a complexity and a finesse far greater than it seems. From the choice of the internal components to the embedded software and circuit topologies, each step of the development process has been essential to enhance the listening experience.
Concept
The philosophy implemented in the Emerson DIGITAL is that of the straight wire: no sampling frequency conversion or data processing is applied, apart from volume control when used. The flow of data from the network interface is transmitted directly to the S/PDIF and AES/EBU modulators of the Emerson DIGITAL, or respectively to the digital-to-analog conversion chip in the case of the Emerson ANALOG. When properly implemented, this solution guarantees a transparent and coloration-free reproduction.
Network Interface
The Madison, as well as both Emerson models leverage Engineered's streaming engine, a proprietary solution based on a Sitara processor from Texas Instruments.
The embedded software, which handles the various network communication protocols and audio stream decoding, has been under continuous development for many years. Internal processes have been optimized to ensure audio data integrity, transmission reliability, support for Hi-Res file formats (PCM and DSD) without transcoding, and a smooth and responsive user experience at the same time.
Clocks
Two clock generators are used alternately, depending on whether the track being played back is sampled at a base frequency of 44.1kHz or 48kHz (as well as any multiples thereof). Our streamers do not include a variable oscillator or a synchronization loop. The stream of audio data is therefore directly cadenced by the active clock.
Additionally, the selected oscillators offer superlative performances, with extremely low phase noise in the audible bandwidth. The distribution of the clock signals has been carefully designed to minimize jitter throughout the digital audio signal path.
Output Stages & DAC
The Emerson DIGITAL uses two separate modulators for the S/PDIF output and the AES/EBU output. This is the only way to meet the specifications of both standards without having to make compromises.
High-speed output stages, synchronized by the main clock to avoid jitter, and two wide-band RF transformers ensure independent isolated outputs and a perfect rejection of common mode problems for superior performances.
For the Emerson ANALOG, a DAC from Cirrus Logic was chosen. This is a well-proven integrated circuit capable of impressive playback quality when optimally implemented. Its power supply, output stages topology and filter circuits required a lot of adjustments, measurements and listening before validating the final solution in accordance with the product philosophy.
Power Supply
The quality of the power supply for sensitive electronic circuits is a decisive factor for a device of this type. Once again, a close attention has been paid to the selection of the components and topologies. The choice of using an external adapter offers the advantage of keeping the mains voltage away from the core of the device. The DC voltage supplied by the external power adapter is smoothed by a series of common and differential mode filters and then delivered to the various components of the electronic board. Each critical section of the circuits benefits from a dedicated filtering and voltage regulator to avoid undesirable interactions.
Finally, the power supplies for the clock generators, the synchronization circuits and the analog section are particularly well performing, with an extremely low electrical noise, less than 1µV RMS (measured in a frequency bandwidth from 10Hz to 100kHz).
