    Using this technology allows maximum amplifier performance under the most demanding and extreme conditions. In the RV-8 there are two amplifier modules. One module consists of three amplifier channels and the other consists of four amplifier channels. Each individual channel is identical schematically, but not identical in the way they are laid out.

  • Page 78: Amplifier Operation

    RV-8 Service Manual Amplifier Operation At the heart of the amplifier is a high performance error amplifier (U2 - TLE2037). From the error amp audio signals move through the voltage translators and on to Q7 (MJE15032) and Q11 (MJE15033). Q7 and Q11 form current gain cells, which feed the paralleled main output devices (MJ21194 NPN, MJ21193 PNP).
  • Page 79 Lexicon Clip The clip signal is derived from the output signal of the error amp. This signal is called V_ERR on the schematic. V_ERR is fed into a window comparator set up by U4-A (LM339D) and U4-B. When the signal coming out of the error amp exceeds ±12.5Vdc it triggers the window comparator. The output of this stage is sent into another comparator stage set up by U4-C.

    RV-8 Service Manual RV-8 ANALOG BOARD THEORY The analog board of the RV-8 encompasses all of the analog audio inputs and outputs, level controls and A/D and D/A converters. This board is located below the RV-8 Video Board. There are three separate signal paths: Main, Zone2 and Zone3. Each of the eight analog stereo inputs, the tuner, the phono, or any of eight digital inputs can be routed to any of the three paths.
  • Page 81 Lexicon 1. An S/PDIF signal may be encoded in Dolby Digital or DTS format and pass through a decoder that outputs the 5.1-channels. These channels are then passed along to the DSP and sent to the analog board. 2. Two sets of three separate analog input pairs can be routed directly to the outputs, bypassing the DSP and converters.
  • Page 82 RV-8 Service Manual SCHEMATIC WALKTHROUGH Analog Audio Inputs (sheets 1,2 & 3) Sheets 1 and 2 are identical. The Left input jacks and associated circuitry are on sheet 1 while sheet 2 includes the Right input jacks and circuitry. Each input pair is buffered by a dual TL072 op amp. Each buffer connects to three DG408 8x1 CMOS switches.
  • Page 83 Lexicon The output of the DAC passes through a second order low-pass filter with its –3dB frequency at 187kHz. The filter topology is a compromise between the flat pass-band Butterworth filter and the Bessel filter with its superb transient response. The filter is flat out to 20kHz. It has an overall gain of 6.7dB when measured at the test points.

The rear channels are switched with separate controls REAR_DACOUT_SEL/ and REAR_DIRECT_SEL/. The output from the analog switch goes to a –6dB level shifter and ADG451 output mute switch. The outputs pass through DC-blocking caps and relays before going to the RCA connectors.

  • Page 98 RV-8 Service Manual Power and Ground Distribution (U16 and U34) The SHARC devices require two supply voltages. One voltage powers the 3.3V IO while the inner core of the device runs off of 1.8V. There are 13 pins on each device that require 3.3V, 14 pins that require 1.8V, and one pin that requires a separate 1.8V to power the internal PLL circuitry.

  • Page 100 RV-8 Service Manual External Register U21 bit map RESREGDECH is decoded from chip select CPUCS3/, write strobe CPUWRH/, and the condition CPUADDR[3:1]==000. The result is an active high strobe when a write operation is performed at CPU address 0x00C00000. This strobe acts as a clock signal for register device U20 on sheet 2. The following table illustrates the register control.
  • Page 101 Lexicon DISP_RS is a decode of CPUCS3/ and the condition CPUADDR[3:1] == 001. This is an active low signal and is a function bank select signal for the VFD. DISP_RW is a read/write strobe for the VFD. When this signal is high, the VFD registers are in read mode.
  • Page 102 DSPATXD, CRY_FCS/, CRY_FINTREQ/, HINBSY During the boot phase of RV-8, algorithm code is loaded into the format FLASH and then into the on- board SRAM. All external memory is accessed through DSPC via its SPI port. As demonstrated with the SHARC devices, the two SPI ports for DSPAB and DSPC are shared, with each one selected by independent chip select signals.
  • Page 103 When this signal is low, the internal clock source is the internal PLL. When high, then all internal logic is driven by the CLKIN pin directly. This signal is significant during the boot phase of RV-8 when the algorithm FLASH U19 is being loaded. Writing to this FLASH can only happen reliably when CLKSEL is high.
  • Page 104 RV-8 Service Manual from the propagation delay of a gate within U7. The resultant signal DELWE/ is the write enable for U19. Software requirements dictate that the FLASH address space begin at 0x80000. U13 decodes out the start address with chip select. When CRY_A19 is high and CRY_NVCS/ is low, pin 4 of U13 goes low.
  • Page 105 Lexicon coming up. This is a likely scenario given the fact that the 3.3V rail is more heavily loaded than the 2.5V rail. There are seven ground pins associated with the core supply, and four associated with the I/O supply. In addition, there are five no connect pins that are recommended by the manufacturer to be tied to GND.
