4.  Inserts
Insert points are useful for adding dynamic processing or equalization to a 
channel, subgroup or the mix. Unlike reverbs, etc., which are usually added to 
the dry signal, dynamic processing is normally applied across an entire signal. 
Here, an aux send would be inappropriate. Instead the signal is intercepted 
somewhere along the channel/subgroup/mix, fed through the dynamics 
processor and/or EQ and then returned to the console at the same point where it 
left. The insert point is invisible or normalized, until a jack is plugged into it.
All subgroups and channels have got insert points, as does the main stereo 
output. Both SEND and RETURN are accommodated on a single stereo 1/4" jack 
socket wired tip=send, ring=return. Inserts are always pre fader and also pre 
EQ / aux sends for channels.
Insert points may also be used as pre EQ direct outputs without interrupting 
the signal flow. This is obvious when looking at the patchbay wiring (section 8, 
fig. 8.1). If you want to insert a dynamics processor post EQ, the insert point must 
either be taken from a subgroup, or via a second channel / aux return as follows:
1)  Insert a compressor/gate/EQ across a subgroup, and route the channel to be 
processed (and only that channel) to that subgroup.
2)  Alternatively, patch a channel’s direct out into a compressor/gate/EQ. 
Take the output from that compressor/gate/EQ and feed it back into the 
desk via a secondary input (channel, aux return, etc.).
Figure 4.1 illustrates how you might insert into a channel post EQ for mixdown or 
track-laying (their requirements are different). Mixdown requires one A and one 
B-channel. Recording requires two A-channels.

◊ 
In this arrangement you might find that compression tends to soften 
the perceived amount of EQ applied. The solution? Apply more EQ. 
This creates a real “pressure” sound, great for high energy music such 
as dance. (For a more subtle approach, use the desk insert points word 
for word.)
◊ 
Using a group insert to effect post EQ processing precludes the use of 
POSTPROCESSING AUX SENDS without some serious re-patching.
5.  Subgroup and Direct Outputs
5.1  Subgroups
The principal routes to the multitrack are via the SUBGROUP OUTPUTS. There are 
four stereo (or eight mono) subgroups, numbered 1 to 8. All main channels 
can access all of them, as can the STEREO AUX RETURNS 1 and 2. (For this 
reason it is usually wise to bring your best two FX processors back on these 
returns (or A-channels, for that matter), so that they can easily be sent to tape. 
(See also section 6.1 “Aux masters”.)
Why are there 16 subgroup output jacks on the EURODESK when there are only 
8 subgroups? Well, each subgroup output is duplicated, so that the EURODESK can 
interface with up to 16 tracks via the group outputs without having to re-patch.
As well as always functioning as subgroups for track laying via the SUBGROUP 
OUTPUTS, groups can be routed directly into the main mix bus for submixing. 
Main mix routing is handled by switches (S37) and (S38). (S37) routes an odd 
numbered group to the left bus, while (S38) sends an even numbered subgroup to 
the right bus. That’s fine for stereo submixes. If you want a pair of mono submixes 
instead, also press the MONO buttons ((S35) and (S36)). Now these subgroups feed 
into the center of the main mix stereo image, i.e. equally to L and R. You could have 
the first subgroup feeding into the left hand side, while the second one appears in 
mono, but we can’t think of many real situations where you’d want to do this.
Subgroup SOLO ((S33) + (S34)) follows the mix assignment. E.g.: If the main mix is 
selected, then that stereo subgroup will be monitored in stereo. If mono is also 
selected, monitoring is in mono.
◊ 
Try inserting compression / de-essing / an exciter / a gate across 
grouped signals (e.g. backing vocals, drums, layered synths).
