Page 5: Installation Of The Mix4
Two BNC connectors are provided for Sync connection to and from the MIX4. The MIX4 takes Word Clock, AES sync and video sync (if the optional sync board is installed) and synchronizes all internal timing to one of these references if instructed by the system Setup software.
Page 6: Mix4 Principle Functions
Level Control Simple Diagram Each of the 4 Channel Strips of the MIX4 can be connected to one of the 14 inputs (sources). Sources 1 and 2 are normally used for microphones but can be used for analog line level signals.
Page 7 The MIX4 has a sophisticated monitoring circuit. In addition to analog line level monitor output for monitor amps and speakers, two headphone level outputs with offset level control are provided. Both outputs have manual level setting by a turn pot at the desktop remote.
Page 8 There is also a serial interface for connection to a PC via RS 232 that serves for configuration of the MIX4. This interface may also be used in RS 422 mode.

Page 12: Operation
A push on the Channel Rotary Knob switches it to the PAN / BALANCE mode. When a mono source - underlined L or R or C - is assigned to the MIX4 Channel Strip it is a PAN function (This might be used when you have say two microphones in an interview situation, with one panned to the left, the other to the right).
Page 13 (s. p. 20). Test tone generator : For testing purpose of outgoing lines you can route a 1kHz test tone to the busses of the MIX4 (s. p. 20). The level of that signal can be set from the desktop remote.

Page 17 Klotz VADIS II In this case, 16 sources for each MIX4, connected to a VADIS system, must be pre-selected in within the “Junger Audio DDE client” (see extra description for VADIS operation). Thus you will get 16 more (external) sources for the MIX4.
Page 18 Jünger Audio-Studiotechnik GmbH Important note! When you are selecting an external source for the MIX4 (see above) there are two ways to leave this mode (see 4.1 or 4.2 below) : Turn source selection mode on by pressing the <SRCE> button.
Page 19: Bus> Assignment And Bit Transparent Mode
<BUS> Assignment and Bit Transparent Mode This is where you route the output of a MIX4 Channel Strip to one or more of the possible buses. Possible buses here are the Mix bus, the Hybrid bus (a function to operate a telephone hybrid that also means a Mix Minus or clean feed to that bus) and the Direct Out bus.

Possible settings are : -22dFS, -20dBFS, -18dBFS, -15dBFS, -9dBFS, -6dBFS, 0dBFS If you turn the generator on you will monitor it automatically via the monitor section of the MIX4. You can decide now on which bus output the test tone is present. Therefore you must press the respective Bus Button.
Page 24: User> Operator Management
In principle the MIX4 knows 10 Operators and one Guest. After turning power on the device is in Guest mode. If one is a registered Operator one can log in to the MIX4 and will then be forced to authorized himself by a four digit PIN-number.
Page 25 Turning the Channel Rotary Knob in channel D selects one of the 8 Snap Shot memories where the actual state of the MIX4 surface (sources of the MIX4 channels, their bus assignments, DSP settings as well as GAIN and PAN / BALANCE) may be stored. Pressing the rotary control D stores the data.
Page 26 Jünger Audio-Studiotechnik GmbH Presets : In addition to the Operator specific Snap Shots, there are 100 Presets which are accessible to all Operators in common. These represent audio parameter of a single source which can be loaded into any Channel Strip to make settings for certain narrators available for all Operators, for example.
Page 27: Setup Of Mix4
14 possible local sources. When turning the MIX4 on for the first time it will be started with a set of standard parameters which relate to the hardware configuration and will ensure moderate levels at the analogue outputs.

0dBFS, the level on the analog output will be +22dBu. The Bus Limiter threshold settings (set in the Digital Pane – see above) and the analog output maximum level set in this pane allow you to fit the MIX4 to any requirement for operating level and head room. Examples: If you want a digital level on the bus of -18dBFS to produce an analog output level of +4dBu, then set the Max.
Page 32 Jünger Audio-Studiotechnik GmbH Headphones pane Both headphone outputs have independent amplifiers and can be adapted individually by the MIX4 remote to fit the desired listening conditions. The maximum output level can be set to +15 dBu. The signal monitored may be selected “Fixed to” one of the “BUSses” or the “PFL” selector or to ”Follow Monitor Selection”.

Page 40: Controlling The Mix4 With Sdi Interface Installed
From the de-embedding side we have access to the 2 pre-selected groups. The decision is made by Setup software (see Source section). For the embedding side one can decide if one wants to embed the MIX4 stereo buses or pairs from the SDI input channels. This is under direct access from the desktop remote unit.
Page 41 The SetUp software of the MIX4 shows on the Hardware- and Sources pages, if a SDI interface is installed : With actual firmware the MIX4 can make use of two of these audio groups at a time. This must be set on the Sources page : This setting applies to the de-embedder as well as to the embedder.

At the same time the number of selectable sources for the MIX4 is limited by the set up functions of the DDE interface to a maximum of 16 and the differentiation between 2 channel and stereo sources will be made here also. Inside the MIX4 sources are always treated as 2ch ones, Therefore a mono source is processed as a ”double mono”...
Page 45 MIX4 ID from 1 – 8. It is obvious that it goes hand in hand with a correct IP number and subnet mask for the MIX4 itself as well as the declaration of the VADIS IP number for the MIX4 (see Router Page in SETUp software).
Page 46: Setup The Mix4 To Remote Control Mandozzi Router
First you must go to the Hardware page and perform a “from Device” to load the current settings into the Setup software. You must assign a unique IP address and subnet mask to the MIX4 as well as a gateway address if necessary (pls. contact the system administrator for IP addresses). Such IP configuration will only be valid after a power cycle of the MIX4.
Page 47 You may disable a group completely if there is no need for as much as 16 groups for the current application of the MIX4. This also applies to the sources within a group. If there is no need for as much as 8 sources per group you should disable the unused ones.
Page 48 If you have set up the sources for the MIX4 you must setup the input configuration. The MIX4 is connected with the router by tie lines. You must tell the MIX4 the output of the Router to which the relevant input is connected.
Page 49: Setup The Mix4 To Remote Control Dhd Rm 4200 Router
Set up the MIX4 to remote control DHD – RM 4200 router functions The procedure to prepare a MIX4 for DHD router remote control is quite simple. Pls. ensure that the MIX4 and the PC, where the Setup software is executed, are connected to the LAN where the DHD router and the PC that holds the CSV type configuration file reside.
Page 50 Jünger Audio-Studiotechnik GmbH If the application port number is different from 2008 that number will appear below the IP number. You must correct it to 2008 for proper operation. Send the Setup “to Device”. Press the “Configuration” soft button on the Router page. This will open a file dialog : From here one must choose the CSV (comma separated) file that contains the actual Device configuration.
Page 51 One may disable a group completely if there is no need for as much as 16 groups for the current application of the MIX4. This also applies for the sources within a group. If there is no need for as much as 8 sources per group one can disable the unused ones.
Page 52 Jünger Audio-Studiotechnik GmbH Each source for the MIX4 can be selected by a pull down box that opens, if one clicks the triangle soft button in the far left column : One can scroll through that list. The selection is made by clicking on a list entry.

If you have lots of connections in use and you would like to transfer such information to a different PC, you must export the registry key which you will find here : HKEY_LOCAL_MACHINE\SOFTWARE\Juenger Audio\SDM4Base\ The example below assumes you are about to mange operator profiles : After you have selected “Operator Profiles”...
Page 57 Jünger Audio-Studiotechnik GmbH The next example shows a list of presets loaded from a device. The entries 1, 3, 4, 5 und 9 have been marked and afterwards moved by <Import> into the “Workspace” : In the “Workspace” the entry number 3 “SM69” is high lighted. The label of the soft button shows now <Edit SM69>.
Page 58 Jünger Audio-Studiotechnik GmbH You must click into a drag label and hold the mouse button down. Now you can change parameters by moving the mouse pointer horizontal. If you click close to the left and right edges inside a drag label, the value jumps to the maximum / minimum of the existing range.
Page 59 Jünger Audio-Studiotechnik GmbH The functions <Backup> and <Restore> allow to store and retransmit operator profiles and presets by a strike without to preview the names and select items. In position „Device“, data of a whole device may be stored as well as restored. This function is from interest for a service case if you must exchange a device.
Page 60: Operating Of A Telephone Hybrid Or Isdn Codec With The Mix4
The first step is to select a Mix4 GPI for signaling an incoming call. The next step is to select a MIX4 Tally output that signal the hybrid to accept the incoming call. On the Desktop-Unit page of the Setup software, a User Button function must be selected to permit direct talking to the hybrid.
Page 61 Jünger Audio-Studiotechnik GmbH An incoming call (signaled by the GPI) will be shown by that Strip’s channel button blinking dark yellow. Pressing that button will take that call by closing the Tally and will activate the PFL function so one can listen to the caller.
Page 62: Mix4 Dynamics - The Junger Multiloop
Principals of Multi-Loop ™ Compressors The Junger Multi-Loop™ also allows adaptive controlling of the parameters of the control loops. The Multi-Loop™ DSP module analyses the structure of the input signal and adjusts the attack and release times automatically to match.
Page 63 6 dB below the Threshold level. The limiter of the MIX4 has an adjustable threshold. It defines the trigger point of the limitation and normally is set to 0 dBFS. If this value is lowered, the rotation point of the compression response curve will be moved in parallel..
Page 64 Jünger Audio-Studiotechnik GmbH Beside overload free and frequency independent dynamic processing the MIX4 utilizes new filter principles. Dynamic filters only take effect up to a certain defined threshold : Static Filter (Range = -10dB) Dynamic Filter (DE-ESSER) This the DE-ESSER makes use of. Here the adaptive controlling adjusts the Threshold dynamically to the processed signal.
Page 65: Level Diagram Of Mix4
The MIX4 operates at the analog inputs up to a level of +22 dBu. This compares to a digital level of 0 dBFS after A/D conversion. E.g. if an analog level of +6 dBu shall cause a digital level of -9 dBFS, a (digital) gain of 7 dB is necessary.
Page 66 Jünger Audio-Studiotechnik GmbH At the output you can set the maximum analogue level based on 0dBFS. For our example one must set the output to +15dBu. I.e. at 0 position of the channel fader and with a channel gain of 0 dB the operating level at the output will be +6dBu again (incl.
