Description
This is a manufacturer-refurbished product (manufacturer-maintained product). [This is an individual manufactured in 2024]Since it has been opened, there are marks on the outer box where the tape was removed and the shipping label was painted on.All accessories are included, but since this is an opened item, the bag of accessories may be different.Renewed with a new design while keeping the basic concept of sa1.0.The sound quality and functions have also been upgraded.?Complete non-feedback discrete circuitThe SA1.0 non-feedback discrete amplifier circuit has been thoroughly reviewed and rebuilt. By improving the drive power of the voltage amplification stage and at the same time reducing the input load on the final stage, we have achieved a wide range while improving drive power across the entire band.?Equipped with two balanced inputsA-0 has two balanced input systems. The balanced input signal is not converted into an unbalanced signal, but is selected in its balanced state, adjusted in volume, and transmitted to the differential input of the voltage amplification stage.? Non-contact wiringIt follows the non-contact signal system adopted in the higher-end model A-1. Connectors are eliminated from the balanced input to the speaker output, making it contactless.?Gain selection switchMoved the gain selector switch to the front panel. In addition, the volume circuit has been revised to minimize changes in sound quality due to gain switching, dramatically improving the dynamism of the sound even at low volumes. By selecting low gain when listening at low volumes, you can now make finer volume adjustments.?Output selection switchA new switch has been added to select between speaker output and pre-out output. You can easily switch between two systems: the speakers connected to the A-0, and the power amplifier and speakers connected to the pre-out.?Super powerful pre-out & headphone outputBoth the pre-out and headphones are output directly from the same non-feedback discrete power amplifier as the speaker output. Since it can drive speakers, it can be called a super powerful preamplifier/headphone driver.?High quality output stageBy intentionally suppressing the maximum output to 10W, which is sufficient for general home use, it is possible to use transistors (2SA1930/2SC5171) with excellent frequency characteristics, linearity, and completion accuracy in the final stage. .By using this in a single push-pull mode, transparent and dynamic sound quality is achieved.It can be said to be a power unpress method that drives speakers with pre-out quality. ?Multi-heat sink methodIn A-0, the heat capacity of the heat sink is twice that of sa1.0. In addition, by separating the heat sinks between the final stage and the driver stage and configuring a temperature compensation circuit tailored to each stage, the stability of idling current is greatly improved, providing both a sense of dynamism and a sense of comfort. is completed.?Ideal construction & pattern layoutBy adopting a full-size chassis, we have achieved the ideal construction refined with A-1. By minimizing the current return loop from the transformer to the rectifier circuit, creating the ideal shortest layout from the power supply circuit to the amplifier circuit, and using star wiring for the ground pattern, the audible S/N and sound reality are improved. It has improved significantly.?Direct mechanical earth constructionBy installing a spike pin directly under the transformer, harmful transformer vibrations are released directly to the outside of the chassis. In addition, by supporting the legs of the product at three points with spike pins, we eliminate the muddiness of the sound caused by chassis dumps and obtain a lively, soulful sound.?Equipped with metal standard insulator (at time of shipment)We have abolished the plastic insulator that was previously standard and have replaced it with a metal insulator that is more particular about sound quality.?SpecificationsOutput Speaker: 10W x 2 (8?), Headphones: 3.0W x 2 (32?), Pre-out: 2.0V (10k?)Total harmonic distortion speaker: 0.2% (10Hz - 100kHz 3.3W 8?), headphones: 0.03% (10Hz - 100kHz 200mW 32?), pre-out: 0.005% (10Hz - 100kHz 2V 10k?)Frequency characteristics Speaker (8? 1W): 5Hz to 350kHz (+0/-1dB), Headphones (32? 200mW): 5Hz to 400kHz (+0/-1dB), Pre-out (10k ?2V): 5Hz to 400kHz (+0/- 1dB)Input sensitivity/impedance LINE1,2: 0.775V/10k?(H), 4.0V/50k?(L), LINE3,4: 0.775V/5k?(H), 4.0V/25k?(L)Total gain H:22dB, L:8dBS/N ratio 115dB (IHF A network)Power supply voltage AC100V 50/60HzPower consumption 31W (J60065), 20W (when idling)Maximum external dimensions Main body: 430(W)×109(H)×418(D)mmMass?8.0kgFor remote delivery areas, additional fees will be charged.
