The BD-3000 conference room special amplifier inherits the international leading professional technology, achieves the extremely high performance index in the circuit design and the effect aspect, makes the music fluent natural, exquisite pure beauty, the human voice level is clear, the pleasing to the ear, is a high quality power amplifier.

The superior double operation amplifier is used to make the front amplifier, with the lower distortion output of the rear amplifier, so that the amplifier has excellent control ability and drives the speakers with low sensitivity, and the timbre performance is also satisfactory.

In order to enhance the cooling effect and stability, the collector circuit grounding design, power amplifier tube directly installed on the radiator, cooling effect and reduce the tube power amplifier is greatly enhanced by high temperature instability or distortion phenomenon, power amplifier tube at the same time, the longer life of both suitable for fixed installation, also suitable for live broadcast field installation, unlimited application in various fields, including classrooms, training room, cinema, amusement park, radio and television, etc.

Bd-3000 power is developed by symmetric double difference circuit design technology, which greatly improves the stability and dynamic range of the input stage and strengthens the control ability of zero drift.

The output adopts complementary collector output design, so that the crossover distortion is less, so that the size of the signal drive is accurate, the timbre is distinct, and has the characteristics of treble thin, bass rich, sound more clear.

BD - 3000 power amplifier adopts maken up of some boards power assembly technology is extremely high level in today's power component: it is combined with the mechanical and electrical is an organic whole, forming an independent heat balance feedback system, of the type of wind tunnel heat balance and unique electric heating technology, the power amplifier working in full power under the rated temperature at 68 degrees Celsius, at the same time, this unique BanKuaiShi power assembly design makes all of the electronic device with temperature in an electric parameters, such as technology platform, is not easy to self-excited;

Good transient response, large dynamic, low background noise, good control force of sound field, and complete protection circuit: temperature control, switching machine buffer, overcurrent, overvoltage, DC protection and so on make BD-3000 power amplifier extremely reliable.

Product Features:

◆ The power amplifier adopts the large-current soft starting technology and the original digital common-touch timing sequence starting technology, so that the starting current of the power amplifier is small and has almost no impact on the power grid.

◆ Three working modes of stereo sound, bridge and parallel connection and three input sensitivity choices of 0.775V/1.0V/1.44V are provided.

High speed, low noise temperature control CVT cooling fan.

◆ Heavy frame and light plate structure design, excellent earthquake resistance, durability, low failure rate.

◆ Conversion rate greater than 45V/MS, providing excellent transient response, making the sound more transparent and clearly layered.

◆ High signal-to-noise ratio (above 105dB), very low background noise.

◆ Signal and clipping LED indicator light can monitor the working state of the amplifier.

◆ Multi-stack integrated protection circuit includes DC, overcurrent, voltage limit, overheat, dynamic automatic amplitude limit protection, so that the amplifier works normally and stablatively
