@ 40 Hz does not fit into most of the modules.
All electronically balanced outputs have a drive capacity of at least + 24
dBu into the nominal load of 600 Ohms between 40 Hz and 15 kHz (worst
case condition).
Nominal level +6dB (or custom level, respectively)
Source impedance < 50 Ohms
CMRR/IEC > 34 dB, typical value 46 dB
Transformer balanced outputs:
If transformer balanced outputs are ordered, the low frequency headroom
is limited by the core saturation level of the transformer itself at low
frequencies. The minimum value of the core saturation is + 26 dBu into
600 Ohms at 40 Hz.
Nominal level +6dB (or custom level, respectively)
Source impedance < 60 Ohms
CMRR/IEC > 34 dB, typical value 46 dB
CMRR/IRT > 60 dB up to 15 kHz
Level Diagram
The entire level diagram of the 5MT console system is flat. The internal
levels of the circuitry are not lower than the external levels of inputs,
insert points and outputs. In combination with the high supply voltage
of +/- 20 Volts this principle results in an overall headroom of more
than + 24 dBu throughout the entire console circuitry. Since full level is
processed on all amplifiers, processing stages and the mixing busses as
well, maximum dynamic range is achieved, also as far as the mix noise is
concerned. The mix noise in particular suffers from a level diagram, that
uses lower internal levels to achieve a nominal higher output level.
3.2 Connector Types
Four versions of the connector panel
The connections for each module type of 5MT consoles are standardized.
There are 4 types of connector panels.
Version 1 is used for type of input modules for consoles with internal
patch bay.
Version 2 is used for all types of input modules for consoles without
internal patch bay.
Version 3 is used for the master section
Version 4 is used for tie jacks with consoles with internal patch bay.
The master panel also contains the power supply connector. One of
these panels is part of each 5MT console.
All connector panels are available with different
versions of multipin connectors. This manual concerns
the D-Sub connector version. Another manual is
available for the 30-Pin Siemens connector version.
Location of the connector panels
The connector panels are mounted right behind the belonging input
modules, the master section and - if installed - the patch bay at the rear
side of the frame. The connector panels are inside the frame and can be
covered by additional rear sheets. A row of metric 4 mm threads allows
the installation of cable clips at the rear bottom of the console frame.
These clips can be used to hold the cable tree. The connector panels are
mounted approximately 75 mm inside the frame.
Routing bus and master bus Assignment
The assignment of the 24 routing bus rails to the module slots is part of
the frame installation. It can be changed by the rearrangement of bridges
on the frame boards. See the drawings of the frame boards for details
on this configuration. This configuration determines which routing bus
is connected to a particular module slot. If not otherwise specified, the
busses will be assigned to the first 24 channels in the frame.
