DESIGN OF AUDIO CONTROL AND MONITOR PANELS FOR ASW FLIGHT TEST PURPOSES

Abstract

An audio control panel and project monitor panels were developed to meet the demands for a convenient and efficient means of routing and recording the audio information derived from the various project receivers aboard a P2V-7 aircraft, and to aid project personnel and coordinating their efforts during test flights. The following features were incorporated in the audio control panel: (1) The patching network was enlarged over that used in the previous audio panel; (2) Each tape recorder input was preceded by a step attenuator; (3) A built-in volume level meter was installed to permit the reading of input levels oe project personnel can monitor any of the inputs to all recorder channels. The tape may also be monitored by means of a downstream reproduction system to check the quality of the recording. By means of auxiliary project monitor panels, the project group is provided with an interphone system tha all recording channels; (4) For playback signal level control and measurement reference, facility was provided for application of a calibration signal to all recorder channels at any time; and (5) The project personnel can monitor any of the inputs to all recorder channels. The tape may also be monitored by means of a downstream reproduction system to check the quality of the recording. By means of auxiliary project monitor panels, the project group is provided with an interphone system that may be operated separately from the regular aircraft intercommunication system (ICS).
