die zijn nutuulk ook een behoorlijk stuk duurder... en waarom zou je meer willen betalen voor iets waar je toch niet al te lang mee bezig bent... kabels ompluggen is nutuulk ook een veel stoerderderderde bezemkastigheid...!Origineel geplaatst door anoniempje
hallo ik zit ook aan een patch bay te denken maar zijn er ook patch bays die niet meteen automatisch doorgeschakeld zijn ??
dat ik gewoon alles zelf aan de voorkant moet in prikken wat ik nodig heb
als alles automatisch is doorgeschakeld zonder dat er kabels aan de voorkant in zitten lijkt me frustrerend werken

What is normalling?
Normalling routes signals automatically between sockets on a jackfield, unless a plug is inserted to replace the 'normalled' signal with another. Patchbays are usually configured to allow a studio to operate with no plugs inserted on the jackfield at all -- sources would be routed automatically to their default console channels, desk outputs routed to the recorder inputs, and the relevant mixer monitoring outputs connected to the loudspeaker amplifiers. What the patchbay really provides is the flexibility to alter the normal signal path.
There are several varieties of normalling, but the most common arrangement is called 'half-normalling', also known as 'listen and break'. Of the two sockets involved in a normalled connection, the first (upper) carries the output of one piece of equipment, and the second (lower) the input to another device -- let's consider a keyboard output and a desk channel line input. The idea is that, under normal conditions, the keyboard will always be connected to the relevant channel line input. However, we might also want to route that keyboard output somewhere else, or we might want to connect an alternative signal to that particular mixer input.
The arrangement shown at the top of this page allows precisely this. The keyboard signal is connected to the spring contacts in the top socket as well as the switching contacts on the bottom socket. The spring contacts of the bottom socket are connected to the mixer input. With nothing connected, the keyboard signal flows past the upper socket and through the switching contacts of the bottom socket, straight to the mixer. If a plug is inserted in the top socket, the keyboard signal can be distributed elsewhere -- this socket is often referred to as a 'Listen' or 'Sniff' socket because it permits the source signal to be listened to -- without changing the signal path to the mixer input.
However, if a plug is inserted into the bottom socket, the spring contacts are pushed away from the switching contacts by the body of the plug. The keyboard signal is therefore broken at these contacts -- hence this socket is referred to as a 'Break' socket. The inserted plug is now connected directly to the mixer input, allowing an alternative signal to be introduced.
On B-gauge and Bantam jack fields, normalling is either hardwired between the contacts of the jack sockets themselves, or performed at a central wiring frame -- each contact of every socket being wired back to this point. The former arrangement makes modification difficult, but the latter, although much more flexible, requires bigger cables and a lot more terminations in the wiring frame! On most A-gauge patchbays, each vertical pair of sockets is mounted on a separate circuit card -- patching sockets on one edge and rear-panel sockets on the other. The normalling facility is provided either by solder links or, more commonly, by reversing the circuit card.
The reversible circuit card enables normalling arrangements to be changed without needing any tools and works because the normalling link is in place all the time. When the normalled pair of connectors are positioned to the rear, the source and destination plugs from the equipment break the link anyway, but if the card is repositioned with the normalled connectors at the front, a half-normalled connection is established between the source and destination.
For the sake of completeness, other common types of normalling are called 'Single' and 'Double'. In single normalling, the switching contacts of both connectors are linked together so that plugging into either the source or the destination socket breaks the normalled signal path -- there is no 'listen' facility without breaking the normalled connection. Double normalling is used to provide better reliability since the switching contacts of both sockets are wired in parallel -- if one set becomes dirty, the second set maintains the signal path. With this arrangement, it is still possible to derive a 'listen' signal without breaking the signal path, but it is necessary to plug leads into both sockets to break the normalled signal path (see diagrams, right).
What should or shouldn't be normalled on the patchbay?
The default connections for the studio should be normalled -- the idea is that the studio should operate without any patching (although it is usual to patch microphones). Line sources such as samplers, keyboards, CD players and so forth should be normalled to their usual input channels. Similarly, group outputs and tape inputs should be normalled, as should their returns. The same applies to the stereo mix output and the master stereo recorder, the monitoring outputs and the loudspeaker amplifiers.
If the desk insert points are brought onto the patchbay, sends should be normalled to their corresponding returns, and if you always have a specific reverb connected to Aux 1, say, then normal those connections too.
Normalled connections should be planned carefully before you connect anything to the patchbay -- the classic cock-up is to accidentally normal the output of a signal processor to its own input, creating a permanent howl-round condition that is definitely not good for the processor!

er zijn schakelbare pachbays, daarop kan je per kanaal instellen waar je signaal naartoe gaat.
