2021 New Saw tooth(Buzzsaw) Single -sounding background
The size of the chassis 300@mm*height 80mm*depth 420mm sawtooth bird dual single channel 250W background introduction:
A high -quality amplifier must have a high -end gorgeous appearance, and it must have an artistic atmosphere from the inside to outside design.The sound performance must be very cost -effective, very good multifunctional input and output interfaces are suitable for the public system.It is necessary to have a powerful driving force and easily control some large food speakers.It also guarantees the sound resistance of the sound.
Dual -single -channel 250W rear -level appearance introduction: In the case of chassis materials, we did not hesitate to use a thickness of 2mm cold rolled plates through high -precision laser cutting and 100 -ton stamping machine bending.Washing and decontamination on the surface and paint pink paint multiple times.Aluminum alloy parts are treated with high -precision multi -axis CNC processing drilling precision and large polishing machine polishing. It must be the best.(Panel color can be confession and black choice, the chassis default black sandblasting process)
Yuanshi dual single -sound road 250W rear materials introduction: The whole machine inside the machine uses a 700VA power ring transformer, and the highest -level new material silicon steel sheet and high -purity 4N oxygen copper wire are used on the materials.Wind by.
In the middle of the transformer, epoxy resin irrigation treatment was performed, and the traditional sandwich cake installation method was abandoned.Personally, it is believed that the use of sandwich cakes will squeeze the wire bag, which will cause the wiring and iron core gaps.There will be a lot of bulls, which will also have a great impact on the sound.The primary and secondary leads of the transformer are directly out of the paint.Although the installation is not as convenient than using multiple wires, the sound will definitely be more performance than using multiple wires.
The power supply system of this machine adopts a fully independent form of power supply. The main release of large circuits, input buffer circuits, protective function circuits, and a total of 3 circuits on each channel are made of multiple independent taps in the transformer.Traffic DC conversion and storage filtering and independent stabilization.
Most of the rear -level power supply rectifier from a high -speed large -current rectifier bridge is used to translate the DC conversion.The stability of the line plays a good role.Practice has proved that large transformers and high -capacity capacitors reserve have a very good effect on improving sound details and accuracy sound fields.
Many foreign inscriptions are also seen everywhere. The three -pair of high -power Golden Flinting Darlin Tube can output strong current driver speakers on the current driver. The differential pipe uses Philips silver bread.The feedback capacitance uses AVX 钽 capacitors that can help medium and high frequencies.There are single -end, balance, and BTL bridge on the input board. Power supply is also a separate set of power supply. The same is to use Anonmei''s rectifier diode and two 1000U capacitors for power treatment. There is no large current component here.Therefore, the use of three -terminal stabilization power supply directly seems to be simple and active.The input single -end and balance signals must be made by the OP op amp on the input board.The purpose is to make the front and back impedance well match, and finally go through another OP op amp for differential cross -guided processing.Everyone knows that the op amp has a direct impact on the sound, so all the two op amps use high -level OP2134/2604.The entire machine connecting plug -in uses high -level materials. The single -end input interface uses Taiwan''s gold -plated RCA. The two balanced seats use the imported gold -plated Nutrilite brand.
Yuanshi dual single -channel 250W back -level function: input interface supports single -end RCA, balance XLR input, and supports two machine bridges to connect the BTL working mode.
After the bridge, the output power is 700W8 European driver a larger food speaker.Sawtooth(The rear level of Buzzsaw is the standard with a dual single -sound latter.Large eclipse speaker nemesis, small figure and big thrust, is a small return on the box of ATC, Dana, PMC and other boxes, and pushes the best solution.The best version of the Jinfengda Linton is neutral, warm and atmospheric, full and powerful, brave and good, pushing a large amount of food speakers.
