Definitions
- the invention relates to a control console for sound signals according to the preamble of the claim.
- a control desk is known (brochures "Studer 900 Professional Regietech ⁇ ik PI 3/82 D / E” from Studer International AG, Rege ⁇ sdorf, Switzerland).
- the object of the invention is to provide a control desk which, with an unchanged operator philosophy, enables both an analog and a digital transmission signal to be generated without the quality of the input signals originating from digital audio signal sources being obtained by digital / analog signals. Change and subsequent
- a hybrid technology is used in the control console according to the invention, the input signals originating from digital audio signal sources first being summed and a further digital signal which corresponds to the sum of the processed analog input signals of the control console being added to this digital sum signal.
- the signal resulting from this represents the digital transmission signal.
- a further analog signal is added to the sum of the processed analog input signals, which is obtained from the sum of the processed digital input signals.
- the resulting signal represents the analog transmission signal.
- Both the analog and the digital transmission signal contain the i d entic modulation.
- the surface of the control desk is practically unchanged and is only replaced by level controls for those from digital audio signal sources originating input signals expanded.
- analog level controls that are no longer required can be replaced by the level controls for the digital audio signal sources.
- the fact that both a digital and an analog transmission signal are generated in parallel with the control desk according to the invention has the further advantage that interference in the digital part does not lead to a transmission failure.
- each digital audio signal source also has a corresponding analog signal output which is connected to analog inputs of the control desk for reserve purposes, so that the signals coming from digital signal sources in the event of an accident occur via the halogen part of the invention Control desks are processed and inserted into the analog transmission signal. Since digital line transmitters have an additional input for an analog transmission signal for reserve reasons, transmission in the event of an accident is also ensured in this way on the purely digital transmission path.
- the control desk illustrated in the drawing has an analog part 10 illustrated on the left half of the drawing and a digital part 20 shown on the right half of the drawing. Both parts 10 and 20 are separated from one another by a broken line for better clarity. separated.
- the analog part 10 comprises a processing section 11, to which a multiplicity of analog input signals A. to A - are supplied. In the processing section 11 there are level controls, filters, switching elements, control devices and the like in the usual way.
- a processed sum signal of the analog input signals A is fed to both an analog / digital converter 12 and a summing element 13.
- the output signal D of the analog / digital converter 12 is fed to the digital part 20, from which an analog signal A is fed to the second input of the summing element 13.
- the output signal of the summing element 13 represents the analog transmission signal, as will be explained in more detail below.
- the digital part 20 has a processing section 21, to which a multiplicity of digital input signals _ ⁇ ale D j _ until D ⁇ _ ⁇ is fed.
- These digital audio signals generally come from digital audio signal sources, such as CD players, DAT recorders or digital signal lines. (e.g. from the slaughterpost).
- the digital processing section 21 consists only of level adjusters since, in addition to leveling, no further processing, such as filtering, is required for the supply of signals from digital audio signal sources. If necessary, the processing section 21 can of course also include digital filters, switching devices and the like. 6
- the processing section 21 comprises control devices, such as e.g. Preview button, digital level display and much more.
- the processing surface of the processing section 21 is, as already mentioned above, inserted into the processing surface of the processing section 11, so that the operating philosophy of analogue control desks familiar to the sound engineer is available.
- the sum signal of the processed input signals is located at the output of the processing section 21
- the output signal D of the analog / digital converter 12 of the analog part 10 is present, which means that the digitized version of the sum of the processed analog signals is supplied to the sum of the processed digital signals.
- the output signal A of the digital / analog converter 22 is, as already mentioned, fed to the second input of the summing element 13 of the analog part 10; this means that the analog version of the sum of the processed digital signals is supplied to the sum of the processed analog signals.
- the output signal of the summing element 23 represents the digital transmission signal. If one compares the transmission signals at the outputs of the summing elements 13 and 23, it is found that both signals
- control desk With the help of the control desk according to the invention, a very inexpensive, fast and flexible entry into digital radio on the studio side is made possible without any loss of quality.
- the need to purchase a large, expensive control desk using purely digital technology is eliminated, as is the need to retrain the sound engineers.
