[. . . ] ® INSTRUCTIONS XA8800MNu POWER AMPLIFIER XA8800MNu Chapter 1 Important Safety Instruction CAUTION ! Dangerous Voltage The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to presence of uninsulated "Dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. ! Important Instructions The exclamation point within an equilateral triangle is intended to alert the user to presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. Marking by the "CE" symbol (shown left) indicates compliance of this device with the EMS (Electrornagnetic Compatibility) and LVD (low voltage directive) standards of the European Community. 1 XA8800MNu Chapter 1 Important Safety Instruction 1. 1 Before Use Please read all instructions and precautions carefully and completely before operating your power amplifier. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus ( including produce heat. [. . . ] The amplifying circuitry design follows the well appraised current negative feedback structure, featuring the full symmetric and full complementary circuit. The most outstanding advantages of this circuitry are powerful drive, low distortion, rich dynamics, excellent controlling ability, reliable work and good sound. The whole amplifying circuitry can be divided into three stages: the first stage adopts quality Motorola MJE350/MJE340 geminate transistors, the second stage adopts Toshiba 2SC517/2SA1930 geminate transistors and the output stage uses three pair of Sanken 2SC3264/2SA1295 high current geminate transistors. The materials are very select, especially some audio-use-only and world famous capacitances are choicely used in the audio loop. It uses imported relay to switch the coaxial channel and balanced channel. The whole power supply system is consisted of the 350W high quality annular transformer as the core, the 50A high speed bridge rectifier and 60, 000 F Rubycon capacitance. The power supply for voltage amplifying is supplied by the filtered and rectified separate windings of the transformer, which have high speed, low noisy, low impedance and strong shielding ability. Besides, the separate design of the two windings can rapidly reduce the intermodulation disturbance and thus increase the purity of the sound. The core of the protect circuitry takes charge of the protect functions against output over current, over voltage and on/off surge with an indicator which will glitter in case of protect. IC was used as the controlling core, therefore, the general sensitivity and reliability is rapidly increased. [. . . ] Change a higher SNR sound. Signal selector switch wrong Root noise of sound source too big Noise too big Signal shielding effect badly Change eligible signal cable Left and right channel confused Signal source input phase opposed Speaker wire to channels has exchanged or positive negative reversed Connect according to the indication of left and right channel.
