WARNING Service on the d8b must only be undertaken by experienced service technicians. ! SMD ! ! ESD ! The d8b makes extensive use of surface mount components. Servicing technicians should have the tools, experience and patience to perform surface mount rework. The d8b contains components that may be damaged by elecrostatic discharge. All standard ESD precautions must be taken when servicing.

INTRODUCTION This manual contains service information for the d8b digital audio mixer. To service the d8b, technicians should be familiar with op-amp based and discrete analog circuitry, digital troubleshooting, microprocessors, digital audio, DSP, ESD, ESP, and the operation/ application of mixing consoles. Presentation of this manual does not constitute endorsement of qualifications by Mackie Designs.
OVERVIEW The ‘Digital’ functions of the d8b can be broken down into 3 main systems; Computer, DSP, and User Interface. The computer is a Pentium system which is contained in the Remote CPU with the Power Supply . It communicates via standard com ports (RS-232) to the DSP and UI systems in the console.
COMPUTER SYSTEM HARDWARE The computer system within the Remote CPU chassis consists of the following hardware; • Computer motherboard • Computer microprocessor • RAM • HDD, FDD • Ethernet® Card • SVGA Video Card • MIDI Card, SMPTE These are all standard PC compatible parts. However, because the drivers are written into the Mackie OS, other similar devices may not be compatible.
CMOS SETUP If you encounter “System Error 43,” Check the following CMOS setup which you can reach during bootup by pressing Del (or F1 depending on the age of the console). • Enter the standard CMOS setup screen, change the Primary Master to AUTO (highlight and use PgUp/PgDn to modify). • Next go to the Advanced CMOS setup and check the following: Ist Boot Device ..................... 2nd Boot Device .................. 3rd Boot Device ................... 4th Boot Device ...................
DSP SYSTEM A simplified block diagram of the DSP system is shown on the next page. At the heart of the system is an Analog Devices ADSP-2181. It acts as the console CPU, and controls all functions and communications within the DSP system. There are 24 proprietary DSP chips to handle the actual audio processing. Parallel processing with the 24 DSPs allows the d8b to complete all processing within one sample. Operating instructions are loaded from the Remote CPU as the system boots.

UI SYSTEM A simplified block diagram of the User Interface system is shown on the next page. Like the DSP system, an Analog Devices ADSP-2181, is used as the CPU. It controls all functions and communications within the UI system. Also, like the DSP system, operating instructions are loaded from the Remote CPU as the system boots. If the UI system does not ‘find’ the Remote CPU, it will display ‘ERROR 43 HOST COMPUTER NOT FOUND’ in the VFD. CLOCKS Unlike the DSP system, the UI system runs on its own clock.

ANALOG SYSTEMS The analog circuits used in the d8b should be familiar to anyone with experience servicing Mackie products. The 12 Mic Pre’s are the same circuit which is used in the SR40•8. The line amps use Mackie’s ‘unity plus’ architecture. DCA BOARD As the name suggests, the DCA board contains Digital Controlled Amplifiers to control the level of analog signals in the console’s monitor section. The DCA board also contains an analog switching matrix to select and route monitor signals.
DSP SIGNAL FLOW The DSP board is the central hub of the signal flow system, the digital signals must find their way to the DSP board, get DSP’d and make their way out again to the big audio ocean. Please take a look at the Block diagrams chapter, especially the diagram on page D3, and the DSP map on the next page. Also see the connectors chapter for details of every connector and pinout. Signal names (golden rule) Throughout the console, you will see digital signal names beginning with DR and DT.
DSP map This table shows the data received (DR) and data transmitted (DT) by the DSP board. On a scale of 1 to 10, you will find this table fairly useful.
DSP CONNECTORS J12 Digital data to and from CODEC This is a compilation of all the DSP board’s connectors, mainly showing the data received and transmitted, and clocks. The power and ground pins are not shown here, to make things a little clearer. These can be found in the connectors chapter, or on the schematics.

CODEC connectors This is a compilation of all the CODEC board’s connectors, mainly showing the analog inputs, data received and transmitted. The power,ground and clocks are not shown, but they can be found in the connectors chapter, or on the schematics.
DCA connectors J11 Analog signals coming in from CODEC board This is a compilation of all the DCA board’s connectors, mainly showing the analog inputs, data received and transmitted. The DCA board receives the analog Buses, Auxes, Mixes and Solos from the DSP board, then outputs (under control by the Brain board) to the Analog I/O board and Bus out.
TAPE CARDS This shows the analog inputs and outputs on the Tape cards. The analog signals go in and out of the rear panel DB25 connectors J101 and J102 respectively. The Tape cards have their own D/A and A/D converters, therefore, only digital signals are passed to and from the DSP board. Pairs of analog inputs are converted to digital form, for example, input 8 and 7 are combined to form digital signal DR4 which goes off to the DSP board.
TAPE CARDS continued CARD TO DIGITAL SIG ANALOG BACKPLANE TAPE OUTPUT NAME ON TAPE BOARD CONNECTOR PAIRS AND PIN NO. WHAT THE SIGNAL BACKPLANE IS CALLED ON TO DSP THE BACKPLANE CONNECTOR AND DSP BOARD AND PIN NO.
EFFECTS CARDS There are four slots available on the backplane board for Effects cards. They can plug into the backplane connectors J51, J16, J14 and J17. The backplane connectors J21 and J24 transmit and receive data to and from the DSP board.In most cases, the digital signals have the same name on the backplane as appear on the DSP board, but there are a few exceptions, shown in the right hand column of the tables below.
EXTRA CARD One slot on the backplane is available for an extra digital I/O card, such as the PDI•8. It connects to backplane connector J22 (in the ALT I/O slot). The signals to and from the DSP board pass through backplane connector J48. There are 4 digital inputs and outputs, each carrying two data signals. CARD TO BACKPLANE CONNECTOR AND PIN # WHAT THE SIGNAL BACKPLANE IS CALLED ON TO DSP BOARD THE BACKPLANE CONNECTOR AND DSP BOARD AND PIN NO.
The clock card The clock card generates the main clock signals used throughout the console. On other boards there are a few local clocks used, for example, for the serial Rx and TX connection to the remote CPU. This table shows the signal flow from the clock card to the various boards in the D8B. The clock card fits into connector J23 on the backplane board.
The clocks The diagram below shows the relationship between the various clock signals generated by the clock card.
MUTE and UNMUTE On the clock card, there is an important Mute/Unmute circuit. It could have been fitted to any board, but it just so happens it was placed on the clock card. Here is the circuit: The UNMUTE and RESET signals come from the DSP board. The MUTE signal will mute the D/A converters (CS4390 pins 15 and 16) on the CODEC board and the Tape Cards. The left column of the table below shows the signals on the CLOCK card. This plugs into the BACKPLANE card connector J23.
POWER ON SYSTEM < POWER OFF System Boots DSP > RESET UNMUTE MUTE TIME As the console powers up, the D/A converters are muted on the CODEC board and the TAPE cards. This prevents noise form being heard or recorded on the Analog lines. When the system has finished booting correctly, the all-important UNMUTE signal is sent from the DSP board to this little circuit, and so the D/A converters are unmuted and ready.

CONNECTORS Connectors This table shows each connector and the boards they connect to. Note that the connectors on each board are joined to the same numbered connector on other boards. For example, J4 on the Analog I/O board connects to J4 on the Mic/Line control surface. The following pages show each connector in detail, including the labeling and designation on each pin on either end of the connecting cable.
CONNECTORS J1 This is J1 on the power distribution board, not to be confused with the other J1 shown opposite, or J1 on the DSP board.
