The aux/bus structure on a Heritage 3000 is really flexible. You have 24 busses which can be switched in pairs between either 2 audio groups, 2
mono auxes or a single stereo aux. This switching takes place at the top of each bus master section in the middle of the
console, on what midas
call the "key routing
switch". If this is not lit, the busses are setup as a sub group, if it is red then it is a pair of
mono auxes, and if it is green it is a stereo aux master. This selection then affects how the aux controls on the individual channels behave.
Each of the 24 "
aux send" controls on the
channel strips also have a built in push
button, with different actions depending on the modes.
In group mode, channels are routed to the group bus through the on/off
switch, with the
level control having no affect on the signal. The
led beneath each
channel shows the status of each assignment.
In
mono aux mode, you have a pair of individual
level controls, with individual on/off, and switchable pre/post. So to
send channel one to say, aux one, you would need to press the aux one knob down. It will click, and the green light will come on, and then you can turn the knob in the usual manner to dial in the amount of signal you want. As a quick note, the Pre/Post
switch has no indicator light and is relatively easy to miss a change in setting, and is worth double checking. On the Heritage 4000, the on/off light changes colour to show pre or post.
In stereo aux mode, the left
hand pot on each
channel becomes the pan, and the right
hand pot becomes the
level and on/off routing as per the
mono channel.
So if you think the desks auxes are behaving strangely, the best place to check is the key routing switches in the middle of the
desk!
The Heritage 3000 brochure on the midas web
page has close up pictures of the
channel strips and master sections which may give you a better idea of how the controls are laid out than my description.
Im only 18 but have been working for a rental company in the UK part time for 3 years, I got given a H3K to
play with in the shop in my first week, and sussed out the routing pretty quickly, its definately easier when you have a surface in front of you.
Hope that is of use
