C.B.I. Releases The EarSplitter 24 Channel Splitter 3 Space (PICTURE SHOWS 16 CHANNEL VERSION) Rack Mount! w/15ft XLR Fan, and 30ft Fan Snakes.
With Isolation Transformers. Call for other options. Thank you
THIS ITEM MAY NOT BE IN STOCK BUT WILL GENERALLY SHIP WITHIN 3 BUSINESS DAYS
In ear monitor systems have become a standard for touring musicians. Most commonly utilizing a small rack that holds all of the wireless transmitters, signal processing and a rack mount mixing board. The stage microphones and instrument signals need to be split to feed both the performer's system and the main sound system.
C.B.I. has developed a splitter snake that will fit perfectly into this type of system. The all new EarSplitter can be built using only two rack spaces which split the signal to both monitors and front of house.
The EarSplitter is available in 16 and 24 channel configurations catering to in ear customers (see other auction). The trunk lengths can be customized along with options such as isolation transformers and ground lifts. Call for quote!
The EarSplitter design is simple and portable for any production considering in ear monitoring.

FACTS ABOUT TRANSFORMERS!:
PARALLEL SPLITS The simplest form of splitter is the parallel type split. This involves taking a mic cable and simply "Y" connecting the plus, minus and ground wires to two other cables.
This method successfully connects the mic to multiple mixing consoles but connects the consoles directly to each other as well. Most modern consoles behave well when connected to each other but keep in mind that there is no DC isolation between them. Also, differences in the impedances of the legs in active balanced inputs of multiple consoles can make the system more susceptible to hums and buzzes caused by outside interference. However, if a system works well with a parallel split, this type is popular because they are simpler to construct and do not require employing isolation transformers - an added expense. If a splitter is to be used in a noisy environment or is to be connected to many different systems (such as a mobile recording setup) the possibility of encountering problems can be lessened by using a microphone splitting transformer as described below.
TRANSFORMER ISOLATED SPLITS In a transformer splitter, the microphone is wired straight through to a "Direct Out" and also to the input of a splitting transformer. (See figure below.) This transformer has a 1:1 turns ratio and its output side is connected to the second or "Isolated" split output. (Transformers with two or more secondaries are used for achieving more than one iso split.)
The transformer will pass the microphone's AC audio signal but will block DC voltage in either direction. Impedances are still reflected from the destination to the source across the transformer just as in a parallel split. Therefore, transformer isolation does NOT change the impedance loading of the circuit and does not allow for an increased number of splits over parallel splitting for impedance reasons alone.
One of the outputs is usually wired as a direct connection because the transformer will also block phantom power (DC). Remember to plan on connecting this direct leg of the split to the console that will be providing the phantom power.
A major benefit of using a transformer split is that it increases each leg's ability to reject interference by improving the "balanced" characteristic of the line (called "Common Mode Rejection" or CMR).
A disadvantage of this type of split is the added expense of the transformers. High quality transformers are essential for providing proper shielding and for preserving the frequency response of the mic signal - don't cut corners here!
