MEDIA ENGINEERING's wide experience in the field of broadcasting and close contact with customers led to the development of a new and modern analog mixing console called MEMIX.

With 15 faders it's featuring up to 32 stereo line inputs plus 32 microphone inputs. MEMIX is to be used in radio broadcasting and preproduction studios. It has a modular structure and is fully equipped with all functionalities needed for professional radio broadcasting. MEMIX is compact, robust and easy to install, test and maintain. There are only four modules (units) and one small printed cicuit board a system engineer needs to know:

  • 19"/1U power supply
  • 19"/4U electronics chassis
  • 4-fader operation unit
  • 3-fader+master operation unit
  • MIC-preamp board
BASIC CONCEPT

The control signals from the faders and the pushbuttons built into the operation units are transmitted to the electronics chassis that is containing all electronic circuits The operation units simply act as remote control devices. They do not contain any audio signal.

HUMAN INTERFACE

There are two types of operation units:
  • The 4-fader operation unit contains 4 faders with 5 pushbuttons assigned to each fader.
  • The 3-fader+master operation unit featuring 3 fader-channels only but it has a master section with 13 pushbuttons.
Both operating units have the same physical size and can be mounted lined up in a row.

All control functions are activated by pushbuttons. This unique feature allows total flexibel control and is solving the well known problem of worn out potentiometers.

For simple operation, MEMIX contains only the essential controls and useful functionalities broadcasters need. Consequently, MEMIX has no pan, filters, routings etc., as these functions are quite often unnecessary and confusing.

MEMIX' flexibility is achieved by a unique feature:

EACH PUSHBUTTON IS PROGRAMMABLE WITH A SPECIAL FUNCTIONALITY

Thus all units are off the shelf and customized as well. Using MEMIX as a console of "European style" or "American style": no problem!

Some programmable functions are:

  • INPUT STEREO LINE A/B selection
  • INPUT MICROPHONE A/B selection
  • CHANNEL ON/OFF
  • FADERSTART ON/OFF
  • GAIN-STEP UP/DOWN/0 dB/PRESET
  • INSERT-RETURN ON/OFF
  • PFL
  • ROUTING TO AUXILIARY OUTPUT 1/2/3
  • ROUTING TO TALKBACK BUS
  • VOLUME CRM UP/DOWN/PRESET
  • VOLUME HEADPHONES UP/DOWN
  • EXTERNAL MONITORING INPUT 1/2/3/4/5/6
    selection
  • MONITORING SUM (main output)
  • MONITORING SUM+EXT. (mixed)
  • TELEPHONE HYBRID ON/OFF

STRUCTURE

The MEMIX operating units can be built into a studio furniture. Due to the flat construction an open view to studio guests or onto touch screen monitors is achieved. The 3-fader plus master operation unit contains a microprocessor board for data exchange with the electronic chassis. All signals originating from the pushbuttons are transmitted to the electronics chassis via a 4-wire RS422 connection. In addition, each VCA fader signal is fed to the chassis. There, the input boards containing all audio and control circuits for channel 1-3 or 4-7 or 8-11 (and so on) are connected to all audio devices in the studio via D-type connectors.

The master board in the electronic chassis sums up all audio busses. It contains all audio outputs as well as a microprocessor for centralized control of all DCAs, solid state analog audio switches and the faderstart relais'. 8 separate relais' are programmable for special purposes (GPOs).
