PCB PARTS LIST NOTES: •Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. •The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. •When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). 560 Ω → 56 × 10 1 → 561 ........................................................

ADJUSTMENT 6.1 IDLE CURRENT ADJUSTMENT The idle current is adjusted in two steps: coarse and fine. Note that the adjustment value for fine adjustment depends on the elapsed time from the coarse adjustment. For the points to be adjusted or measured, see Table 6-1 and Fig. 6- 1. For the adjustment timing and values, see Table 6-2. Be sure to turn VR501, VR502, VR601 and VR602 fully counter- clockwise before turning the power on. 6.2 DC OFFSET ADJUSTMENT Adjust the DC offset with the power on immediately before fine adjustment of the idle current. For the points to be adjusted or measured, and the adjustment values, see Table 6-3 and Fig. 6-1. 6.3 OPERATION CHECK OF THE PROTECTION CIRCUIT While supplying a sine wave of 1 Hz, 1.2 Vrms in DUAL MODE, with ATT.THROUGH OFF, increase the volume level and check that the protection circuit activates before the level reaches the maximum value.

Basics 1.1 Reset Perform the reset when connecting the AC power supply. 1.2 BACKUP Mode Backup is performed when the AC power is turned off. SPRYH (port 16) and SPRYG (port 17) are set to "L" 10 ms after the BACKUP port becomes "L." All the indicators and lamps go dark. Execution of the BACKUP processes (port processing and register processing) begins 30 ms later. Last memory writing to the EEPROM is performed each time a key is operated, but not performed in the backup processes. Port processing 1) I/O ports are specified as output ports. 2) Output ports are set to "L." Backup targets INPUT1/2, ATT.THROUGH, ATT. HOLD (The level value is also backed up when ON), ILL. (The VOLUME level and mode settings at the mechanical switch are checked each time the power is turned on.) As writing to ROM may require 40 ms at maximum, 5 V will be supplied to the microcomputer for about 100 ms after the AC power is turned off at the hardware. The data to be written are composed of the following 3 bytes: BRD. DUAL Bright / dark / off PRO. ON/OFF ON/OFF 1/2 ILL INPUT ATT. THR ATT. HOLD ATT. LEVEL At ATT.

Input-independent last memory is not provided. The ILL and ATT.THROUGH settings remain the same in switching between INPUT 1 and 2. 1.4 TEST Mode None 1.5 SILENT Mode The unit can enter SILENT mode in a condition other than the following: • The BACKUP port is "L." (BACKUP mode) • A volume operation is being processed. • A key input is being processed. • Caution status for mode switching (caution indication state at the operation of OPERATION MODE SW during Power-On state) When 200 ms have elapsed after such a process is completed, the unit can enter SILENT mode. The unit restarts upon key input, a volume operation, mode switching, or P-DET input. The timer is set for 5-second restarting. When 200 ms have elapsed after the restarting process is completed, the unit can enter SILENT mode again. (SILENT mode : The control µ-com enter the low power consump- tion mode and stops the oscillation of system clock.) 1.6 POWER ON/OFF (1) POWER ON After POWER ON, port 16 (SPRYH)(Pin16) is set to "L" and port 31 (FMT)(Pin31) is set to "H." Port 31 (FMT) is set to "L" after 3 seconds, and muting is set to OFF. After another 5 seconds (8 seconds after POWER ON), ports 16 (SPRYH) and 17 (SPRYG)(Pin17) are set to "H," and relay is set to ON. Power ON 3 sec 5 sec 16 (SPRYH) 31 (FMT) (2) POWER OFF Port 16 (SPRYH)(Pin16) is set to "L" 10 ms after POWER OFF (port 26 (BACKUP)(Pin26) becomes "L"). Ports that must be processed other than port 16 are operated immediately after this. 10 msec 26 (BACKUP) 16 (SPRYH) 2. Initializing The main routine starts after reset processing. Normal processing starts after the initializing process is completed with "initcont". The data read during the reset processing are written to RAM. (See the "1. Basics"(P.43).) If the MODE switch was not operated during the POWER OFF period, the read data are written to RAM. If the MODE switch was operated during the POWER OFF period, the default settings are made.

When these protection circuits are activated ,the hardware muting is activated and muting and the output relays are controlled by the microcomputer. There are two protection circuits. 1) DC voltage detection at the output 2) Overcurrent detection due to the short circuit at the load end 1. DC voltage detection circuit At the High-CH (Low-CH) output current amp of C.AMP (L)ASSY, DC voltage is detected by Q507 and Q509 (Q508 and Q510) and these transistors turned ON and P-DET signal becomes Low. When P-DET signal becomes Low ,relay control Tr. Q515 ,Q511 and Q512 becomes open and shut down the relay RY501 and RY502. Also microcomputer receive P-DET Low signal and activate the mute circuit and set OFF the relay control Tr. Q513. 2. Overcurrent detection circuit At the High-CH (Low-CH) output current amp of C.AMP (L)ASSY, (+) side overcurrent is detected by Q503 and Q505 (Q518,Q504 and Q506) and these transistors turned ON and P-DET signal becomes Low.

Three types of speaker drive formats can be selected. 1. SEPARATE mode The product functions as a 4-channel power amplifier (115 watts, 4 ohms for each of 4 channels). By connecting to a 2-way channel divider, a high-grade multi-amplifier system can be established. Using two units of this product provides a Hi-Fi surround system for up to 8 channels. The product can also be used for DVD multi- channel audio, DOLBY DIGITAL, and DTS applications. 2. DUAL mode By connecting speakers that conform to tandem-wiring use, a Bi- amplifier (tandem amplifier) system can be established. By driving tweeters and woofers separately with different amplifiers, interference between speaker units is virtually eliminated. Thus, super hi-fi stereo playback with a high degree of purity is enabled. 3. BRIDGE mode The product functions as bridge-output high-power amplifiers (230 watts, 6 ohms for each of 2 channels). Symmetrical twin-stereo structure High-performance stereo amplifiers are symmetrically mounted left and right. Of course in SEPARATE or DUAL mode, enlargement of a large current loop can be eliminated even in BRIDGE mode, restraining sound degradation due to magnetic coupling, which is a disadvantage of bridge amplifiers. The important parts are isolated by shield plates and shield cases to achieve excellent channel separation at high frequencies (104 dB or more at 20 kHz between the left and right channels). You can enjoy high-grade stereophonic playback in a rich sound field. Advanced direct-energy MOSFET power amplifiers This product employs MOSFETs of larger capacity than with conventional models. For insulation between each large heat sink and MOSFET, a quite small zero-resistance ceramic sheet is employed to improve the radiation characteristics. Not only a rise in temperature with continuous signal input, but also instantaneous rises in temperature with pulse-type input can be minimized. For higher sound quality, the response speed to an input of large sound volume and the clarity are highly improved. In addition, a newly developed Z (ZETT) BIAS circuit that precisely reproduces the thermal factors of a MOSFET is mounted for temperature compensation for the idle current. This drastically improves the drift of the idle current which may greatly affect sound quality, and enables playback at constantly stable sound quality immediately after you turn on the power. Wide-range linear circuit The wide range linear circuit has been enhanced to improve DC stability by newly employing highly accurate parts of 0.5% error and single-chip dual transistors for a completely discrete structure that uses no DC servo or operational amplifier. This enables natural and clear playback of low frequencies by keeping NFB stable from very low frequencies. DAC (Digital Accurate Control) attenuator A high-precision 12-bit D/A converter of ladder resistance type is used. Advantages of the DAC attenuator (when compared with conventional mechanical sliding-type controls) 1. Excellent S/N in practical usage 2. The frequency response is not affected by the attenuation volume setting. 3. The attenuation volume can be programmed. This product provides two curves, for high-frequency attenuation in a multi- amplifier system and for normal volume control. 4. No tracking error (gain error between channels) 5. No signal irregularity from vibration, providing pure sound 6. The operation block and the circuit block can be separated. The signal path length can be minimized by free layout. Large-sized super ring toroidal transformer A large-sized super ring toroidal transformer of 450 VA is employed for the lowest possible loss and lowest impedance at the power block. In addition, repression of power harmonics, which has been regarded as impossible with large-capacity toroidal transformer, has been achieved, enabling powerful and smooth playback at high speeds. Silent control microcomputer When the knobs and buttons are not operated, the control microcomputer enters Low-Power-Consumption mode (system clock oscillation stops). This decreases power consumption, and eliminates high-frequency interference caused by clock oscillation to maintain high sound quality. In addition, the microcomputer continuously monitors the amplifier status and if it detects an abnormality, it immediately activates the protection circuit. By using the microcomputer in combination with the conventional hardware- protection circuit, higher reliability and safety are ensured. Ultra-Low-Impedance Power Circuit Power de-coupling by an ultra-low-impedance condenser, ample jumper lines and a No. 16 wire power cable are employed for very low impedance in the power and ground lines. In the low frequency range, channel separation is greatly improved (achieving 115 dB at 20 Hz) by decreasing ground common impedance. In the high frequency range, the rise in impedance due to the inductance component is suppressed, for higher frequency stability. Thus a power amplifier that is virtually impervious to changes in speaker impedance and connection cables has been created. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 55 M-AX10 7.3.2 Circuit Description Block Diagram + – + – + – + – + – µ-COM EEPROM 1V/50kΩ Input 2 (Low ch) 12dB FLAT AMP ±30V Power Amp Current Stage (Full-wave voltage doubler rectifier) (for Rch same as L ch) ±40V Power Amp Current Stage FLAT AMP 14dB POWER AMP Input 1 (High ch) Silent microcomputer Interruption ATT DATA input KEY input MODE SW INDICATOR FUNC MUTE MODE RY INPUT RY PROTECTION RY ATT CONTROL Protection circuit detection AC ON/OFF information BACK UP RESET Backup Microcomputer Microcomputer LOCAL CIRCUT ON/OFF MUTE 10A(/KU/CA) 4A (/NY) Vref Iout MUTE Protection circuit detection Red Blk Blk Red Low ch OUTPUT VOLTAGE DUAL SEPARATE BRIDGE 37.1V(200W)/6Ω 20V(100W)/4Ω High ch +5V DAC IC LED LED 15V 24V + ~ ~ – 24V 5V Microcomputer RY AC for Lch LED Bridge ±18V Op Amp IC AC IN www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 56 M-AX10 IN 1 IN 2 Each mode of block diagram 12dB 12dB 14dB 14dB DAC VR – Dual Drive Mode – Low ch High ch + + + + RED BLK RED BLK RED BLK RED BLK RED BLK RED BLK Low ch High ch 12dB 12dB 14dB 14dB DAC VR – Separate Drive Mode – Low ch High ch + + + + IN 1 IN 2 12dB 12dB 14dB 14dB DAC VR – Bridge Drive Mode – Full Range + + + – www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 57 M-AX10 Descriptions of the Block Diagram 1. INPUT switching block Four small-signal relays for individual channels are used for input signal switching. 2. 12-dB flat amplifier block The input signal is amplified by 12 dB (4 times) to increase the input level at the DAC attenuator block to improve the dynamic range and signal-to-noise ratio. In DUAL or BRIDGE mode, the flat amplifier on the low-channel side is shut down by the LOCAL CIRCUIT OFF circuit. The circuits are mounted in a shielded box to completely eliminate electrostatic and magnetic coupling. 3. DAC attenuator block Attenuator section This is a digitally controlled high-precision analog attenuator that uses a ladder resistance block of R-2R-type DAC ICs for volume control. The signal is input to the Vref (reference-voltage) terminal and the attenuated signal current is obtained from the Iout (current- output) terminal. The signal at this terminal is converted to a voltage signal by an I-V converter of the operational amplifier. An output signal of the same phase as the input signal is obtained through inversion by the operational amplifier. The attenuation volume adjustment is controlled using serial data from the microcomputer. Control section A 5-bit (31-position) digital rotary switch is used. The rotation angle and information can be sent to the microcomputer, enabling the silent function (Low-Power-Consumption mode) of the microcomputer. Two DAC ICs are used for two individual channels. There is no mechanical contact, resulting in fewer errors in attenuation volume and gang errors within 0.1 dB at any position. The attenuation volume can be flexibly adjusted by the microcomputer software. With this product, it can be set in 2-dB steps (up to -58 dB) in BRIDGE mode and in 0.5 dB steps (up to -15 dB) in SEPARATE mode. When this product is used in combination with a preamplifier, you can bypass the DAC attenuator block using the ATT.THROUGH function. For this bypass switching, the same small-signal relay as with the INPUT switching clock is used. 4. 14-dB power amplifier block Pioneer's original "Direct-Energy MOSFET Amplifier" and "Wide- Range Linear Circuits" are mounted. The circuits function as the inversion/noninversion switching amplifier on the high-channel side and as an inversion amplifier in BRIDGE mode. This eliminates the necessity for an inversion amplifier otherwise essential for a bridge amplifier. 5. Protection circuit When a DC voltage at the output end or a short circuit at the load end is detected, hardware muting is activated and muting and output relays are controlled by the microcomputer. When a short circuit at the load end is detected, a resistance inserted between the MOSFET drain power sources is used (for current detection) in place of a bridge detection circuit, a device greatly affected by the phase difference between the output power voltage and current. Thus, possible malfunction of the protection circuit in practical use is prevented. 6. Power block A large (450-VA) Super Ring is employed for the transformer. The second coils are separated into three coil windings for left channel, right channel, and a subcircuit. For the power amplifier, a full-wave voltage doubler rectifier system is used to suppress high-frequency current. For the voltage amplifier, a half-wave voltage doubler rectifier system is used to obtain the specified voltage without using additional coils. Each signal stage has a local stabilized power source, and the lamps are driven at a constant current for low power consumption. 40dBV (100Vrms) 30dBV 20dBV (10Vrms) 10dBV 1Vrms 4Vrms, 12dBV 40Vrms, 32dBV 20Vrms, 26dBV Bridge Dual Separate 0dBV (1Vrms) -10dBV Maximum permission input level with attenuator (4Vrms) Input 1, 2 Speaker Out Input high, low 12dB 0dB (-58dB MIN) 20dB Bridge 14dB Dual, Separate Input Buffer Amp.

PANEL FACILITIES AND SPECIFICATIONS FRONT SECTION 1 0 - 8 ~ 9 = 4 3 2 6 5 7 1 POWER Press to switch the appliance on and off. 2 OPERATION MODE Use this to switch between the three modes: bridge,dual and separate. Be sure to turn the power off before switching between modes. Switching with the power on will activate the warning circuit. The mode illumination light and mode indicator will flash, and the output will be muted. If it happens, you should turn the operation mode switch back to its original position. The flashing will stop, and your M-AX10 will return to normal. 3 ATT HOLD This button is activated only if the OPERATION MODE switch is pointing to SEPARATE. Press the ATT HOLD (attenuator hold) button while in separate mode allows whatever atten- uation has been set with the ATTENUATOR knob to be retained. Pressing it again will cancel the operation. Note,however, that it is not possible to turn ATT HOLD on and off while the output is muted (eight seconds after switching the power on). 4 ATT THROUGH BEWARE: If this button is used ,the volume will be herted at maximum level. Pressing the ATT THROUGH button for two seconds or longer causes the sound to be output through the speakers without passing through the attenuator circuit. However, because the mute circuit is activated, thereis no sound for five seconds after the button is depressed. The sound will emerge from the speakers five seconds after the ATT THROUGH button is pressed. Note that it will be maximaum volume. Pressing the button again will cancel the operation. 5 ILLUMINATION Pressing the ILLUMINATION button once, twice or three times alters the brightness of the panel light, mode indicator as indicated below.
