While mixing, the IO5-D/e module can be used in dual mode. Both signal chains of the module, Tape Chain and Record Chain, can feed the mix bus in parallel. The 24 bus routing of the module can not only used for recording and additional aux sends but for audio sub groups as well. It is possible to assign the routing matrix to the tape or the record chain. Both chains can be used as sub group master alternatively

Stereo Master, Pan Pot's and Sub Groups

By default, the stereo master mix is driven from the tape chain. The tape chaine fader output drives the mix bus via the mix pan. However, it iis possible to drive the mix pan from the record chain as well. A second pan pot, the RT Pan can be inserted into the signal path from the record fader to the routing matrix by the PAN switch. It controls the relation between the odd and the even numbered busses. The output of the record fader drives the mix bus when the MIX switch is pressed. The RT Pan is always inserted in this signal path.

The Pan Pots are rotary controls with center detend. The center attenuation is 3 dB, which maintains are pure direction control that does not change the level.

TO RTG

The TO RTG switch next to the Mix Pan switched the mix bus off and routs the mix pan output to the input of the routing matrix with the highest prority. This function overrides any other signal that is assigned to the routing matrix. The same function is implemented with the IO5-D/c inline channel.

TO RTG makes it possible to arrange audio sub groups on the fly without the need to consider the level relations and the pan settings. By pressing TO RTG, exactly the level that was sent to the mix bus now drives the input of the routing matrix. If a pair of routing busses is selected, that are not otherwise needed, these busses become a subgroup that mirrors level and pan settings exactly. This principle offers the choice to arrange any number of audio subgroups up to a maximum of 12 stereo at any time.

Sub Group Master Chains

With the IO5-D/e inline channel, either the tape chain or the record chain of any channel can be used as audio sub group master. While one of the chains is used as master, the other chain can still be used as input. The INP switch selects the output of the routing bus amp as tape chain input signal, while SUB assigns the bus amp to the record chain input. No patching is necessary for this method; however, one of the signal chains of channel 1 must be the master of bus 1. Of course it is possible to patch the bus amp signal to any other channel. Using the patch bay makes possible to use stereo channels or stereo return inputs as stereo sub group masters.

The audio subgroup system of the 5MT Series D mixing consoles is not limited to only one level. A particular subgroup master can be routed to another routing bus. It is possible to configure up to 12 sub group levels by using this method,
