Choke coils power input circuit
Attention impact power quality on the sound quality, and, like voltage amplifier with a power buffer amplifier preamp section power supply circuit uses a high performance power smoothing choke input circuits. Compared with typical capacitor input mode, inserted between the rectifier diode and smoothing capacitors choke choke input mode, the pulse ingredients rarely, waveform near sine wave, ruled out the higher harmonic components harmful to the sound quality. This helps achieve high s/n sense of tone.
Large-capacity capacitor module
Are important parts of a transformer power supply capacitor modules ultra low audio frequencies to enhance the sense of drive and improve loose as the goal, from 22,000 mF 33,000mF bulk. Highest quality Needless to say, using the parts after repeated hearing tests, and attention to the speed selected on the basis of.
Equipped with high precision power meter
Configuration of power meter in the center of the front panel, namely Marantz past sea #9 rings. The detection performance of the power meter with high accuracy, coupled with -10dB ~ 0dB, 10dB step within the framework of equal-interval scale, so you can visually control the speaker and amplifier red zone standards. The power meter using the blue LED can be a beautiful light, design is also very prominent. Lighting and power meter can also use the switch on the front panel.
3 system input produced by WBT speaker output terminals
Output terminal has equipped 3 systems, 1 balancing system, 2 unbalanced system. Use the knob on the front panel makes it simple to switch. Even if it is used in combination with models other than, or you can use input Attenuator is set to the appropriate input level. In addition, due to the speaker terminals are equipped with 2 sets of Germany produced by WBT speaker terminals of high grade, therefore easy to use wires to connect.
