On 2011, Weiss Medea is replaced by new generation MEDEA+

This because of the new analog section we built for the MEDEA – a new D/A converter chip augmented by eight of our in-house designed discrete operational amplifiers. A truly state of the art design which makes the MEDEA+ a top performer amongst Audio D/A Converters. All MEDEA units can be upgraded with this new analog section.

What MEDEA+ users say:

“We have had a chance to spend time with the Medea+ with Firewire.  All I can say is .. WOW.  It is amazing.  I listened with a TAD system (CR1s, Viola Labs preamp, various amplifiers) and also with a highly resolving headphone setup (Woo WES and Stax 009s).  Mighty impressive!”

“What I’ve felt this week-end is beyond words. Again this evening I’ve been transfixed by the music during hours… “Beast” was not the appropriate adjective for the Medea+: it puts out the most refined sound one could possibly imagine.
I congratulate you… you are doing a beautiful profession indeed…”

Other upgrades available for MEDEA or MEDEA+ are:

- A Firewire interface. The Firewire interface allows to connect the Medea to PC or MAC computers for music file playback via the MEDEA. The features of the Firewire interface are the same as those of the INT202 interface as shown here. Information on computer based music playback can be found here.

- A ST type glass fiber optical input. This input allows to connect e.g. the JASON CD Transport to the MEDEA via a glass fiber cable for uncompromised signal transmission.

Please contact us for upgrade path. Older Medea can be upgrade to latest Medea+, Firewire (CAS playback) and AT&T Fiber Optic (matched with Jason)

The MEDEA+ is a stereo 24 bit / 192kHz Digital to Analog converter designed with the aim of keeping an absolutely uncompromised audio signal path. Much detail and thought was spent on the digital input as well as the analog output stage.

Both have in common the purest possible approach in audio design, aspiring for nothing less than excellence. This is coupled with an ergonomic design that gives the user immediate access to all necessary functions, while keeping an uncluttered and thus easy-to-use front panel. This combination makes a truly professional D/A converter catering for the highest expectations.

We engineers at Weiss refuse to accept any compromises in both electronics or software. We built the MEDEA to be immune to jitter down to subsonic frequencies. This means you simply forget about expensive digital audio cables. We also incorporated upsampling (oversampling) right into the DSP, taking the same algorithms as used in our professional audio product range. And we made the analog outputs not only Class A but also very low impedance, which assures that the MEDEA flawlessly drives subsequent cables and input stages.

Features:

Digital Inputs: 

Input #1 & #2 – Two AES/EBU inputs on XLR connectors, Two S/PDIF inputs on RCA connectors.
Input #3 – Firewire Input for computer connection
Input #4 – One AT&T Fiber Optic Input. One Toslink input.
The accepted sampling frequencies are 44.1, 48, 88.2, 96, 176.4 and 192 kHz.

Synchronization:

Several signal reclocking schemes are combined for extremely high jitter attenuation, making the MEDEA virtually immune to jitter over a very wide bandwidth. In the case of the Firewire input the master clock is contained in the Medea+.

DSP Algorithms: 

For Jitter reduction and upsampling.

Converters:

Four channels of 32bit D/A conversion are used per audio channel. The paralleling of channels lowers converter imperfections, an additional boost in signal to noise ratio and linearity.

Analogue Outputs:
All analogue processing is done with our own discrete operational amplifier modules, the Wiess OP1-BP. The OP1-BP is arguably the best audio operational amplifier currently available. Four OP1-BP are used per channel, two for current to voltage conversion, and two for the balanced and unbalanced output stages. The OP1-BP run in class A mode for all common loads. Output levels can be set with a rotary switch at the back of the unit. The level range is 32dB with a 1dB step resolution.

Power Supply:

An overrated, non-switching power supply is used. All sensitive voltages have their own regulators which are separated between left and right channels. The result is an analog output free from “digital noise” and channel crosstalk.

Mechanical Design:
The MEDEA employs a twin metal frame. The inner chassis is made of steel and acts as a very effective shield against electrostatic and electromagnetic radiation. The outer frame is made of thick anodized aluminium for additional shielding, for optimal heat convection and for beautiful looks of course.

Frontpanel controls:

• Four switches with corresponding blue LEDs are used for selecting one out of four input sources.
• Power switch
