INPUT MODULES

Every module has three selectable inputs. There is a microphone input on XLR, and two
stereo line inputs on cinch connectors and a Start connector.
The mic input is a professional balanced input
circuit, this means that you now have a
studio-class microphone-channel at your disposal.
A microphone is an instrument that turns
acoustical signals in electrical ones, without any
amplification (in most cases).
These very small signals have to be amplified
without any noise and interference from the
mixing table. The Discom 4 is equipped for this
purpose. Instead of one sensitive connection at
the input channel, the Discom 4 has 2 connections
per channel (balanced). This is a major difference
between the Discom 4 and other disco mixers.
It is now possible to connect the 2 wires in your
microphone cable to the balanced input as
follows:
- One wire to pin 2 of the XLR connector.
- The other wire to pin 3 of the XLR connector.
- The shielding on the remaining pin 1 of the
connector.
What are the advantages of this system ?
A microphone cable connected in this way is
completely insensitive for outside interference.
STEREO LINE
The stereo line inputs need to be connected as follows.
The left cinch connector is the left input and the right Cinch connector is the right input.
The shield needs to be connected to the ground.
The START switch has two active connections to be wired. The tip and ring are shorted when
the ON switch or optional faderswitch is activated.
The controls of the input modules have the following functions.
