Description
This is a high-end power amplifier that was used in the 800D3 series listening sessions.This is a genuine Naspec product.Rare bi-wiring + dual mono + fully balanced amplifier.It is powerful and sounds quite good.It is black with a high-class feel, and the appearance is also in pretty good condition.Accessories Original box, instruction manualClear and powerful reproduction sound with excellent transient and distortion ratioThe huge custom-made toroidal power transformer with a capacity of 2,000VA is used,The power supply consists of filter capacitors with a total capacitance of 180,000?F,The power supply consists of filter capacitors with a total capacitance of 180,000µF, and 8 parallel push-pull outputs with 16 high-speed bipolar transistors per channel.The high power output of 400 watts (into 4 ohms) is provided by an 8-parallel push-pull output stage using 16 high-speed bipolar transistors per channel,The high power output of 400W (into 4 ohms) with 8 parallel push-pull output stages using 16 high-speed bipolar transistors per channel, together with the use of SMD technology, etc., provides clear and powerful reproduction with excellent transient and distortion.?A32The A32 is Primares signature dual mono stereo power amplifier for high power and clean sound.The massive custom-made toroidal transformer in the power supply section has two independent windings per L/R, for a total of four windings.Unbalanced inputs are converted to balanced signals to maximize the benefits of a fully balanced circuit.The output stage is an 8-parallel pushbull configuration using 16 high-current bipolar transistors to achieve a high power output of 250W × 2 (8?).The output stage uses 16 high-current bipolar transistors in an 8-parallel push-button configuration. Although it is a class-AB operation, it is designed to operate almost as a class-A operation in actual use by applying sufficient bias current.The design is based on the class-A operation. This is a high-performance power amplifier that can drive any speaker to its full potential.Output StageThe output stage is an 8-parallel pushbull configuration using 16 high-current bipolar transistors.The output stage is composed of 16 high-current bipolar transistors in an 8-parallel push-button configuration.Although it is a class-AB operation, it is designed to operate almost as a class-A operation in actual use by applying sufficient bias current.The circuit is designed to drive all types of speakers to the fullest.Circuit DesignSMD (Surface Mount Device) prevents signal interference and contributes to the shortest circuit path.The transient characteristics and distortion ratio are excellent, and while being clear and powerful, it also delivers a delicate expression of the sound field.The dual mono configuration and fully balanced design, in which the left and right channels are completely independent from the power supply unit, thoroughly eliminates crosstalk and external noise interference.interference from external noise. Unbalanced input signals are converted to balanced signals to take full advantage of the fully balanced design.The unbalanced input signal is converted to a balanced signal to take full advantage of the fully balanced design.Power SupplyThe power supply is a massive 2,000 VA audio-grade 2,000 VA power supply with four independent windings on the L/R balanced outputs.The power supply consists of a massive 2,000 VA audio-grade toroidal transformer with four independent windings on the L/R balanced outputs, and smoothing power supply capacitors reaching 90,000 ?F per channel per channel.The power supply is capable of supplying high-power, high-speed, and clean power with plenty of margin even at high output power.Protection CircuitProtection circuits are provided against DC offset, temperature rise, and short-circuit of speaker output,A relay is used instead of a thermistor to prevent rush current when the power is turned on so as not to affect the power supply,This design prioritizes sound quality.Speaker Terminal?Speaker Output TerminalHigh-quality WBT speaker terminals are used for sound purity.Two speaker output terminals are provided to support bi-wiring.
