- Page 9 THEORY OF OPERATION Input/Output (I/O) PCB (continued) Power supply failure monitor level translator There are four power supplies on the power amplifier PCB, derived as two pairs of symmetrical bipolar supplies. By tying each of these supplies into a node by appropriate resistor values, we have a node that sits at zero volts when all supplies are normal.
- Page 10 THEORY OF OPERATION Digital Signal Processor (DSP) PCB (continued) Power Supplies There are several sets of internal power supply voltage rails. These voltages originate with the main power transformer located in the center of the Input/Output (I/O) PCB. There is also a small keep-alive transformer T5 [I/O PCB schematic, C1] located on the I/O board itself that allows the amplifier to be turned on by SmartSpeaker commands.

- Page 12 THEORY OF OPERATION Digital Signal Processor (DSP) PCB (continued) Microcontroller (continued) 6. Other ADC ports are used for the following functions: • To monitor the gross DC offset on the five satellite speaker channels. Excessive DC offset is assumed to be an indication of a serious problem and the microcontroller will respond to this by shutting off the power to the amplifier.
- Page 13 THEORY OF OPERATION Digital Signal Processor (DSP) PCB (continued) Codec (continued) The codec generates three output signals, either from the 11.2896 MHz crystal, or from the input S/PDIF bitstream; • a serial bit stream containing the 20-bit audio data. • a bit_clock, which indicates when to sample the serial bit stream.
- Page 14 THEORY OF OPERATION Digital Signal Processor (DSP) PCB (continued) Signal Path The signal path through the system takes the following route(s): For analog signals, the L/R stereo pair is introduced from the source via the input cable from the Input/Output board and the 14-pin connector J9 [schematic sheet 1, A-D8]. Each signal is received pseudo-differentially by op-amp U105 [B/C6] and associated components and -6 dB of gain is applied to match with the maximum in/out signal level of the codec (1Vrms).
- Page 15 THEORY OF OPERATION Digital Signal Processor (DSP) PCB (continued) Power-Up Sequence (continued) The microcontroller proceeds to: • Set up its I/O ports. • Print out a “reset” message on the TTY output. • Program the codec and verify that it responds. •...
- Page 16 THEORY OF OPERATION Detailed Theory of Operation (see schematic diagram SD256431) Digital Signal Processor (DSP) Board, Sheet 1 of 4 (continued) The S/PDIF input enters the DSP board at J9 pin 10 [B8] and is routed to the codec by means of C151, R1, R2, D1, C1, C7 and R5 [B5].
- Page 17 THEORY OF OPERATION Detailed Theory of Operation (see schematic diagram SD256431) Digital Signal Processor (DSP) Board, Sheet 1 of 4 (continued) Analog output buffers consists of U103, U104 [B-D2], and associated components. Gain is set by the ratio of R132 to R131 [D2]; to about 6x. Note that the ratio of R189 to R188 [D2] must match.
- Page 18 THEORY OF OPERATION Detailed Theory of Operation (see schematic diagram SD256431) Digital Signal Processor (DSP) Board, Sheet 2 of 4 (continued) Q200 [C2] allows the microcontroller to pull down on the DSP’s reset line. When the microcontroller first boots, all of its output ports are set to a high impedance state. Q200 remains turned on by R252, which holds the DSPs in reset, until the microcontroller is ready to boot the DSPs.
- Page 19 THEORY OF OPERATION Detailed Theory of Operation (see schematic diagram SD256431) Digital Signal Processor (DSP) Board, Sheet 4 of 4 (continued) C506 [D3] is the “soft-start” capacitor, which forces the regulator to start up slowly when power is first applied, thus limiting the inrush current. R510 and Q500 [D3] allow the “soft-start” pin to be pulled low, shutting off the regulator.
- Page 20 THEORY OF OPERATION Detailed Theory of Operation (see schematic diagram SD256421) Power Amplifier Board, Bass Channel Power Amplifier (continued) Short circuit protection is provided through current sense resistor R822. At greater than 16A, Q726 conducts and triggers the one-shot op-amp circuit U707, pins 5, 6 and 7, and mutes the amp for several seconds.

The mute and standby signals for the power amplifiers are brought into the amplifier board at J700 on pins 15, 16 and 18. - Page 22 DISASSEMBLY/ASSEMBLY PROCEDURES 4.3 Align the power transformer (4) with the 8.
