The fader control position facilitates this interchangeable use. The Console Circuit. — The basic circuit for the console is shown in Fig. 6. It is arranged to connect to incoming or outgoing circuits of 200 ohms impedance. Equipment patching points are provided at a number of places within the circuit to permit the insertion of apparatus, such as equalizers, when needed. All apparatus patched into the console circuit is likewise designed for 200 ohms image FIG. 5. Rear of refecording console with cover panels removed. impedances. The patching points permit the inserting of apparatus to affect the signals of the incoming circuits in groups of one, two, four, or the total of circuits. This has been found to be a practical setup for the rerecording work of our studios. It affords a maximum of flexibility in the use of patched in apparatus, but, more important, the mixer is able to use variable networks with groups of sound tracks thus reducing his mechanical work. The patching points are obtained by the use of the transformers shown which are known as mixer transformers. This transformer is an extended design of the well-known hybrid coil, the revised design of which was developed at Metro-Goldwyn-Mayer Studios for our
