The fader section of the IO5-D/c Inline Module is completed by some additional functions, that offer a couple of interesting features. Besides the peak present indicitors, there is the fader reverse function and the AUX function that makes it possible to use the record chain fader as an automated aux send in several different ways.

Additional Functions of the Fader Section

Peak Present Indicator

A peak present inidcator is assigned to each fader. It reads the peak level at the input of the fader. The indicator uses a multi color LED that displays a level above -20 dB with green color. At 0 dB, the color changes to yellow. While the level increases above 0 dB the color changes via orange to red. With red color, there is still a headroom of 5 dB. This principle of level indication is well tried for more than 20 years. It offers a very good overview of all the levels of the entire console.

Fader Reverse

The Fader Reverse Function (FDR) flips both the faders and their assigned control elements like CUT, PFL, Solo and the automation interface controls. In normal mode, the main fader controls the tape chain level (multitrack out to mix) while the short fader controls the record chain level (mic or line input to routing matrix). The FDR swiches exchanges the faders but leaves the basic signal unchanged. This is the major difference between the Input Reverse Function REV and the Fader Reverse Function FDR. You can use the fader reverse swtich to assign the two fader in a way that offers the best comfort and overview for your task.


The Aux switch rearranges the fader section to offer some additional features that are useful while mixing. In normal mode the two faders operate independently. If AUX is pressed, the second fader is coupled to the main fader. To make the principle easier to understand, let us assume that FDR2 is post FDR1 when AUX is active. In this mode, FDR2 works like an auxilliary send. This offers two possibilities.

FDR2 operates as automated Aux Send
FDR2 drives the routing matrix of the channel. If the routing system is not needed for another purpose in that particular channel, it is possible to use free routing busses as floating aux sends. In this case, FDR2 operates as a simple aux send, however, there are two differences. Since the FDR2 is automated, this floating aux send can of course be automated too. Though the Series D mixing consoles do not offer level automated auxilliaries, this way makes it possible to apply this feature on the fly in some channels where it is useful.
FDR2 operates as automated Send Master
The pre and post fader signals of FDR2 are available on all the sends of the module. The single REC switches per send make it possible to switch each send either to the tape chain or the record chain. The AUX function assigns the record chain to the post fader signal of the tape chain. Therefore the REC switches of the sends can be now used to select the FDR2. In this mode, FDR2 becomes an automated aux master send. This mode does not block the routing matrix. It can still be used for recording or audio sub groups, while FDR2 operates as automated send master for all aux sends that are assigned.

Actually, FDR2 is not always assigned post FDR1. With AUX pressed, the SOLO ON switch becomes a PRE switch that makes it possible to select the input of FDR1 alternatively. This offers the choice to use FDR1 and FDR2 with the same input signal, however, independent level control is possible.

The Fader Reverse Function is not affected by the AUX swtich. Also in AUX mode, it is possible to flip both the faders. Therefore, FDR1 and FDR2 in the above examples can be the main fader or the small fader, depending on the state of the FDR switch.
