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) 6500 IEC 60065 paragraph 9.1.1. With the unit switch first in the ON position and then in OFF position, measure from a known earth ground (metal water-pipe, conduit, etc.) to all exposed metal parts of the unit (antennas, handle bracket, metal cabinet, screw-heads, 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 the exposed metallic part has a return path to the chassis, the reading should be between 2 and 5.2 Megohms. When testing 3 wire products, the resistance measured to the product enclosure should be between 2 and infinite Meg ohms. Also, the resistance measured to exposed output/input connectors should be between 4 and infinite Meg ohms. When testing 2 wire products, the resistance measured to exposed output/input connectors should be between 4 and infinite Meg ohms. 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. 2 Specifications Physical Description: Dimensions: Weight: Cover: Base: Display: Inputs: TAPE: AUX: VCR: TV: Digital: Composite video: S-Video: Component video: Optical input: FM antenna: AM antenna: TV sensor: Power: Serial data port: Remote control receiver: Outputs: Speaker Zone 1: Speaker Zone 2: Record L and R: Record digital: Optical output: Composite video: S-Video: IR: FM Tuner: Tuning range: De-emphasis: Channel spacing: Sensitivity, mono usable: Stereo, 50 dB quieting: Signal-to-noise @ 65 dBf: Noise ratio @ 65 dBf: Harmonic distortion, 1 kHz, @ 65dBf Capture ratio @ 45 dBf: AM rejection @ 45 dBf: Adjacent channel selectivity, 200 kHz, for both channels, @ 45 dBf: Alternate channel selectivity, 400 kHz, for both channels, @ 45 dBF: Image rejection: RF inter-modulation: Sub-carrier product rejection @ 65 dBf: Frequency response 30 Hz-15 kHz: Stereo channel separation @ 1 kHz: Auto stop level (seek): Mono/Stereo threshold: 15.8" W x 11.0" D x 3.5" H (40.1 x 27.9 x 8.9 cm) 8.2 lbs.

This amp is configured as a voltage follower (providing no signal gain). The drive is capable of playing DVD-video discs (including CSS decoding).

Communication to the VFD is serial through J103. An ATAPI cable for data and separate power cable connect the drive to the Main PCB (see sheet 2 of SD254135). The outputs of these filters are fed to active band-pass filters constructed of sections of U303. The power detection circuit is built around U303. and L303 form a similar filter about 31500 Hz. and line-doubled. The outputs of these active band-pass filters (if present) are rectified and summed by D302. D303 performs a voltage shift equal to that of the rectifier so that a reference voltage for the comparator can be generated with diode drop compensation. The Schmidt trigger section. or 480p monitors use 31500 Hz. The comparator compares the rectified signal with 0. C325. the comparator output will go high. The circuit detects the presence of the television’s horizontal sweep frequency. The remainder of U303 serves as a comparator and a Schmidt trigger. C328 and L302 form a highly peaked low-pass filter about 15750 Hz. designed to minimize chatter at the circuit output. the active filters have a Q of 5 (allowing for component variation) and a gain of 20.

Theory of Operation 8.0 LS28/35 Bass Module Issues The LS28/35 bass module is sold as a system with the AV28 media center and is mentioned for reference. Refer to the Lifestyle® 28 and 35 Digital Acoustimass® Powered Speakers service manual part number 264562. 8.1 LEDs The amber and green LEDs on the DSP board serve to provide information about the status and operation of the speaker’s DSP board. The following is a summary of the various possible states of the LEDs and a functional description of the state(s) represented. • Green LED: The green LED serves a dual purpose: general system health and serial data received. The green LED will blink once per second with a 50% duty cycle (i.e. on for ½ second, off for ½ second) if the system booted and is running normally. If the unit is in the SmartSpeaker “Off” condition, the green LED will blink briefly (approx. 0.1s ON time) once every 5 seconds. • The green LED will also toggle whenever a serial data byte is received. This will interrupt the normal 1-second blink rate. The green LED blinking faster than 1 Hz usually indicates that it is receiving serial communications. Amber LED: The amber LED serves to signal 3 conditions: power applied/boot status, S/ PDIF status and clipping status. When power is first applied the amber LED will light briefly. If the PROM FLASH checksum is incorrect or hardware does not pass power-on self test, the green LED and amber LED will alternately blink at approx. a 5 Hz rate. If the green LED is blinking at its normal, 1 Hz rate, a blinking, 1Hz amber light indicates that there is no valid S/PDIF signal present: If the amber LED is off while the green LED is blinking normally, then valid S/PDIF is present and being received. Finally, the amber LED will briefly blink (in this case, only when valid S/PDIF is present) when the satellite amps are clipping. This should only occur when playing the system at extremely high levels. 8.2 DIP Switches The LS28/35 bass module has a set of four DIP switches, accessible from the back connector area. Three of these switches (switches 1, 2 and 3) set the Room Code of the speaker, and must match the three Room Code DIP switches on the remote control (switches 7, 8 and 9) used with that speaker. Switch 4 on the speaker is only used in manufacturing/test to enter TAP mode, and should nominally be left DOWN. 9.0 Legacy Speaker Issues 9.1 Protocol Setup The AV28 media center supports legacy (existing) Bose® powered speaker systems in both Zone 1 and Zone 2. However, these systems (AM25P/30P II digital bass module and LSA) require the console to send control commands using the older CD-5 Serial Data Port Protocol, which is NOT the default smart speaker protocol used by AV28 media center. To enable this older protocol, the user must use the OSD (Settings/Setup) menus to change either the Zone 1 Speaker Protocol or Zone 2 Speaker Protocol from “Normal” to “Legacy” mode. • 26 Theory of Operation 9.2 Addressing The older CD-5 smart speaker protocol allowed addressing up to four speakers (“rooms”) per zone, referred-to as Speakers A, B, C and D. Similarly, older Bose® Lifestyle® remote controls had four DIP switches used for selecting which of these speakers should be controlled. All AM25P/30P II digital bass module powered speakers are hard-wired as smart speaker address A. All LSA’s are hard-wired as address B. The AV28 media center's RF remote has three Room Code DIP switches (not implemented at printing of this manual), allowing up to seven speakers per zone to be addressed, referred-to as Rooms A through G. Since this addressing scheme is different than that used by older systems, a translation table is required to understand how to use AV28 media center’s RF remote when controlling AM25P/30P II digital bass module or LSA (when a zone is set for legacy mode), as follows: Postman RF Remote Room Switches for Legacy Mode Postman Remote's Room Resulting CD5 Smart DIP Switch Pattern Speaker Message's (switches 7,8&9) Header 000 (Room A) 0x31 001 (Room B) 0x35 *010 (Room C) 0x39 011 (Room D) 0x3D 100 (Room E) 0x32 101 (Room F) 0x36 *110 (Room G) 0x3A 111 (All Rooms) 0x3E Legacy Speaker that the Console Allows This Remote to Control Cobalt I #1 Cobalt I #2 Cobalt I #3 All Rooms LSA #1 LSA #2 LSA #3 All Rooms The table shows that up to three AM25P/30P II digital bass module’s and three LSA’s (labelled #1, #2 and #3 here) can be addressed by a AV28 media center remote control. Note that a special adapter box would be required to actually hang more than one AM25P/30P II digital bass module and one LSA off each zone of the AV28 media center . *To control a single AM25P/30P II digital bass module, it is recommended that the user set switches 7, 8 & 9 on the user’s AV28 RF remote to 010 (Room C, where 0=down and 1=up). To control a single LSA, it is recommended that a user set these switches to 110 (Room G). 27 Theory of Operation 10.0 Software 10.1 FLASH Update Capability The software in the AV28 media center is stored in FLASH. During boot, the software is decompressed from the FLASH to the DRAM, where it is executed. U1 can update the contents of the FLASH, so the software is field upgrade-able. Additionally, the console can update the FLASH where the DSP stores its code in the LS28/35 bass module using the speaker cable. 10.2 FLASH Update Procedure Note: A software update disc can be obtained by calling Bose service. If you have a software update disc, check the service intranet site or call Bose service to make sure you have the latest version. 10.3 Software Version To find out which version of software is loaded in a console, first press the [ALL OFF] button on the keypad. Next, press and hold the [STORE] key and press the [ENTER] key one time. The software version is displayed on the VFD in the following format: SV C:(dateCode):(version)-(build) – for example, SV C:092501:1.0-0125 would indicate Version 1.0 code made from build #125 on September 25, 2001. 10.4 User Settings Stored in FLASH Certain user settings (tuner presets, OSD settings like preference for Film-EQ in a particular source) and tuner calibration coefficients are stored in a protected area of FLASH. These are not overwritten when the software is updated. There are two important consequences: • Sending an FU [Flash Update] command via ETAP will erase the user settings (but not the tuner calibration). • After setting any preferences (house code, tuner presets, OSD settings), you must cycle the power on and off with the remote and wait a few seconds before unplugging the unit. When the unit is powered off by the remote, the user preferences set in that session are stored in FLASH. 28 4. Top Cover Replacement 2. 5. lift out the DVD/CD assembly (1).
