NEW 2015 Sept: You may now add UPnP/DLNA option to MEDEA/MEDEA+

The MEDEA+ is a reference class 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.

There are three AES/EBU inputs on XLR connectors, and one on Toslink (optical). In addition each of the four inputs has an S/PDIF (RCA) connector wired in parallel. The accepted sampling frequencies are 44.1, 48, 88.2, 96, 176.4 and 192 kHz.
Several signal reclocking schemes are combined for extremely high jitter attenuation, making the MEDEA virtually immune to jitter over a very wide bandwidth.
Multibit sigma-delta D/A converters are used. Our correlation technique which combines two converters per channel gives the MEDEA an additional boost in signal to noise ratio and linearity.

The discrete Class A outputs have a virtually zero Ohm output impedance, but still can drive complex loads without stability problems. Output levels can be set between -infinity and +27dBu. The outputs are symmetrical on XLR connectors and asymmetrical on RCA connectors. They do not have any sound degrading servo mechanisms built in.

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.
Two trimmers set the output levels, one for the left, one for the right channel.
