Remote Control Console 9 4.3 Level Adjustments 4.3.1 Transmit Side Adjustments The transmit audio consists of multiple audio sources – microphone audio, AUX input, function tones, and DTMF tones. Each audio sources is summed or generated in the DSP with the analog signal being generated on a single DAC. The following is a list of the potentiometers that affect the transmit path.
10 Vega’s C-2002 5 Hardware Overview The C-2002 is a Two-line, multi-mode console designed specifically for small to medium level system requirements. All functions are housed in a single small modern looking console. 5.1 C-2002 Console The C-2002 consists of the following sub-assemblies enclosed in the single case: Main Processing Board, Keypad PCB and Display. 5.1.1 Main PCB The Main PCB is mounted to the bottom of the enclosure using 4 #6 screws.
Remote Control Console 11 6 Theory of Operation The C-2002 is a Digital Signal Processor (DSP) based product. Because of this, many of the signals that once could be probed on older products, are handled within the DSP itself. This would include DTMF generators and decoders, notch filters, tone generators and decoders, and all of the audio summing. A great deal of the gain controls are included within the software of the DSP.
12 6.4 System Clock Generation Vega’s C-2002 The system clock is derived from a single 32.7680MHz Crystal Oscillator (Y1). The ADSP2189 DSP (U1) processor uses this clock to generate a 65.536MHz internal instruction clock rate. The system clock is routed to the Altera EPM7032AE44 PLD (U5) and divided into the signals necessary for audio processing. These signals include the MCLK (2.048MHz), SCLK (512kHz), LRCLK (8kHz) and FS (16kHz frame sync). Another signal generate by the PLD is B0 (U5-28).
13 Remote Control Console 7 Setup Mode 7.1 Tech Mode The tech mode allows a technician to program the internal settings of the C-2002 console. The tech mode is entered by pressing MUTE-F6-* simultaneously. The technician will be required to enter a PIN number to allow entry. See the section 7.4.4.1 on setting up the PIN number. The Opening Menu is displayed when tech mode is entered.
