240 WARN September can be made within half an hour by the normal operating personnel. The change from density to area, or vice versa, is also accomplished with a set of parts, in this case consisting chiefly of the modulator unit and light valve. Direct positive recording is also being made available by means of a conversion kit. There are two types of Westrex re-recorders. One is for 100-mil standard density or area track and the other for 100-mil standard, 100-mil push-pull, and 200-mil push-pull tracks, density or area. Fig. 3 — Westrex M4AB re-recording mixer console. On the push-pull re-recorder the change in tracks is achieved simply by turning an indicator knob and switching the phototube control from standard to push-pull. These re-recorders have a loop capacity of 25 feet. In addition, the base loop cabinet on which the rerecorder is mounted has a 30-foot capacity. There is a door at the top of the re-recorder for the extension of the loop upward and the base cabinet has removable side plates which make possible the use of adjacent cabinets for the running of very long loops. An automatic rewind with variable speed is available if required.
