SAFETY INFORMATION

1. Parts that have special safety characteristics are identified by the symbol on schematics

or by special notes on the parts list. Use only replacement parts that have critical characteristics recommended by the manufacturer.

2. Make leakage current or resistance measurements to determine that exposed parts are acceptably insulated from the supply circuit before returning the unit to the customer. Use the following checks to perform these measurements:

A. Leakage Current Hot Check-With the unit completely reassembled, plug the AC line cord directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a leakage current tester or a metering system that complies with American National Standards Institute (ANSI) C101.1 "Leakage Current for Appliances" and Underwriters Laboratories (UL) UL6500 / UL60065 / IEC 60065 paragraph 9.1.1. With the unit AC switch first in the ON position and then in OFF position, measure from a known earth ground (metal waterpipe, conduit, etc.) to all exposed metal parts of the unit (antennas, handle bracket, metal cabinet, screwheads, metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical return path to the chassis. Any current measured must not exceed 0.5 milliamp. Reverse the unit power cord plug in the outlet and repeat test. ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE UNIT TO THE CUSTOMER.

B. Insulation Resistance Test Cold Check-(1) Unplug the power supply and connect a jumper wire between the two prongs of the plug. (2) Turn on the power switch of the unit. (3) Measure the resistance with an ohmmeter between the jumpered AC plug and each exposed metallic cabinet part on the unit. When testing 3 wire products, the resistance measured to the product enclosure should be between 2 and infinite MOhms. Also, the resistance measured to exposed input/output connectors should be between 4 and infinite MOhms. When testing 2 wire products, the resistance measured to exposed input/output connectors should be between 4 and infinite MOhms. If it is not within the limits specified, there is the possibility of a shock hazard, and the unit must be repaired and rechecked before it is returned to the customer.

ELECTROSTATIC DISCHARGE SENSITIVE (ESDS)

DEVICE HANDLING

This unit contains ESDS devices. We recommend the following precautions when repairing, replacing, or transporting ESDS devices:

• Perform work at an electrically grounded work station.

• Wear wrist straps that connect to the station or heel straps that connect to conductive floor mats.

• Avoid touching the leads or contacts of ESDS devices or PC boards even if properly grounded. Handle boards by the edges only.

• Transport or store ESDS devices in ESD protective bags, bins, or totes. Do not insert unprotected devices into materials such as plastic, polystyrene foam, clear plastic bags, bubble wrap or plastic trays.

TEST PROCEDURES

Test Setup:

1. The arrow buttons navigate through the user interface settings; Mono, Stereo, Bass Array and separate channel operation.

2. The rotary control selects the type of speaker EQ under test e.g. 402, 802, LT4402 etc.

3. For the following test procedures, set the unit to Stereo setting and then use the rotary control to select the EQ to test.

Note: The Panaray® system digital controller has the equalized frequency responses for all of the Bose® professional speakers programmed into a DSP integrated circuit.

Prior to testing for frequency response, check that the system responds to key pad entries. Press the arrow keys to navigate through the EQ selection settings. Rotate the rotary pot and check that the display changes from one type of speaker equalization to another. If these functions are working properly then continue on to the frequency response tests. If these functions are not working, the unit may be defective.

Required Test Equipment:

• Audio Signal Generator

• dB Meter

1.5 Measure the frequency response of the output using the table below.

THEORY OF OPERATION

The following is a brief functional description of the main and front panel PCBs for the Panaray System Digital Controller.

Main PCB Overview

The main PCB includes the following features and main functional components:

• DSP for audio processing with associated SRAM and Flash memory

• Analog audio input

• Analog audio output

• MIDI interface (Input, Output)

• Support for 44.1 kHz

• Serial SPI interface to front panel

Front Panel PCB Overview

The front panel PCB includes the following features and main functional components:

• AVR microprocessor for handling display, keys, LEDs and encoder

• Reset

• 2 x 16 character display

• Keys and LEDs

• Encoder

• Standby button

THEORY OF OPERATION

Power Supply

The power supply is a primary switch mode power supply (SMPS) which generates DC voltages for the main PCB and front panel PCB.

Most digital logic runs at 3.3V to minimize power consumption. A few digital components run on a 5V digital voltage. The a 5V low noise analog voltage which is generated on the main PCB by linear regulation from +15V.

The DC voltages from the power supply is led to the front panel PCB as well.

The total maximum power consumption is below 15 Watts.

The power supply used on the Panaray are no schematic diagrams available for it. The entire power supply PCB should be replaced in the event of a failure.

DSP Circuit

+ 15V voltage is primarily used by the analog circuits. Each CODEC has

®

Digital Controller is non-repairable. As a result, there

The DSP (Digital Signal Processor) is the heart of the main PCB. This is the device that performs the sound processing and is the host processor of the system. The DSP is a 24 bit 56362 Digital Signal Processor from Motorola, which runs with a clock frequency of 100 MHz.

The DSP receives analog audio (through CODEC #1). These audio signals are transferred to the DSP as serial digital data. The DSP processes the audio data as defined in software programs and transmits the processed audio data to the CODECs for analog output.

The DSP has attached 24 x 128 bit of fast SRAM. Software programs are transferred from Flash to SRAM and executed from there. The SRAM is also used for temporary data storage.

The 8 x 256k bit Flash stores the programs to be executed in the DSP. Also presets are stored in Flash memory. The Flash can be programmed in-circuit.

Boot

The DSP can either boot from the Flash or from the serial port interface. Flash boot is default. If SPI boot is required, the “SPI_DOWNLOAD” signal must be pulled high. Booting from serial port interface is an option which can be used for downloading new software to the Flash memory. Downloading new code can be done directly on the connector to the MIDI port. When downloading through the MIDI port, data is sent to the microcontroller on the front panel PCB. The microcontroller has access to the DSP RESET pin and the serial port interface. This way the data can be retransmitted to the DSP through serial port interface.

JTAG

The DSP has a JTAG interface, which is used for debugging and hardware testing.

57

THEORY OF OPERATION

Clock Circuit

The clock circuit selects and distributes the correct clock frequency to the rest of the main PCB. The clock circuit is formed upon one independent clock oscillator, which is a NAND gate crystal oscillator.

The clock oscillator is the base frequency for the 44.1 kHz sample frequency. The frequency of the oscillator is 512 times the sample frequency. The clock oscillator has its own enable signal. When the enable signal is high, the clock oscillator is active. There is a pull-up resistor on the clock oscillator which ensures that the oscillator will start running during power up and reset conditions.

The DSP core and CODEC #1 and #2 always runs at the crystal oscillator frequency.

Analog/Digital Audio Routing

The block diagram, Figure 4, shows the routing for the analog and digital audio signals. The analog inputs and outputs are balanced, thus pin 3 should be connected to pin 1 when used with unbalanced equipment. Both the input and output levels are controlled by the DSP. CODEC #1 converts the analog input signal to a digital signal. The DSP performs the sound processing and the digital signal is forwarded to CODEC #1 and #2 where the signals are converted back to analog signals.

Front Panel AVR Microprocessor

The microprocessor controls the display, encoder, keys and LEDs on the front panel PCB. The microprocessor communicates with the DSP through a serial port interface.

Reset

The master reset controls the microprocessor. The microcontroller has access to the DSP RESET pin so after the microcontroller wakes up it pulls the DSP out of reset.

Display

The display is a 2 x 16 character with back lighting.

Keys and LEDs

On the front panel PCB there are six keys. Four of the keys have built-in LEDs. The keys and LEDs are part of a matrix circuit which are constantly scanned by the microprocessor.
