4.2 Live situation
Fig. 4.2: Live situation: example of typical connection scheme
For live applications all instruments are connected to the Main input channels. Since the Mix-B input channels
are not used for the Tape Return bus (as in the studio), these inputs can be used for keyboards, sound
modules, etc. It should be noted though that the TO MAIN MIX button in the Mix-B Main section must be
pressed and the LEVEL control for the Mix-B bus set to 12 oclock. The Main Mix outputs feed the power amps
of the P.A. system. Therefore, the buttons 2-TRACK or MIX-B in the MON/CTRL section should be up, so that
you can monitor the Main Mix bus. Aux Sends 1 & 2 are used to feed the monitor system and should therefore
be set pre-fader. These Aux Sends derive their signals from the Main input channels (SOURCE button up); all
effect sends are assigned to Aux Sends 3 through 6.
If two monitor paths are not enough, you can also use the Mix-B bus as a stereo monitor bus, for example to
drive two side-fill speakers. For this purpose, press Mix-B channels SOURCE button. Make sure that the
TO MAIN MIX button in the Mix-B section is up (not pressed); otherwise, the monitor mix would also be sent to
the FOH system.
The Subgroups can be used to create, for example, a sub-mix of all drum instruments. In this way, you can
control the overall level of the drums with just two faders.
In a live situation, the vocals are often not loud enough and cant make themselves heard, even though they
may be processed with Compressors or their faders may be fully up. If you have a Subgroup with no signals
assigned, you can route the vocals to this Subgroups and adapt their levels there.
If you consider using dynamic processors, you should patch these devices to the Subgroup inserts. As the
Main input channels are most often used for the monitor mix, a Compressor in the channel insert would raise
the signal level in soft passages and induce feedback in the monitor system.
4.3 Patchbay
A Patchbay allows to patch the audio signals of most components in your studio from a central point and send
them to other units, which makes your entire cabling better structured and is indispensable for professional
work. If you want to use your studio as effectively as possible then it is preferable to use a complete Patchbay
wiring scheme, but even less sophisticated patchbay solutions will benefit smaller studio configurations.
4.3.1 Patchbay configuration
The majority of commercially available Patchbays include two rows with 24 phone jacks each in a 19" 1 HU
rack panel. On the rear, either a corresponding number of phone jacks or contacts for soldering signal leads
can be found. Each group of four of these phone jacks forms one module. The configuration of some
