Description: DescriptionCondition : NewLow noise balanced input amplifier with a S/N ratio (GAIN MAX) of 130 dB (guaranteed value: approx. 3% improvement from A 250).The input amplifier circuit is newly designed in a full-discrete configuration to achieve the lowest noise in its history. Higher output power of the power amplifier increases the Class-A operating range by 25% compared to the A250.High-efficiency large toroidal transformer.Large filter capacitor (100000uF).MOS FET 20-parallel output stage (replaced Toshiba MOS FETs with Fairchild MOS FETs).Ideal speaker drive due to low impedance of the entire power amplifier.Damping Factor (DF) is significantly increased from DF=1400 of A250 to DF=2,000 or more.A large bus bar provides both a low impedance output and an ideal grounding structure.Feedback from the immediate vicinity of the speaker terminals provides complete control of back EMFs from the speaker (balanced remote sensing).A MOS FET switch with low ON-resistance of 1.6 mΩ is used as the speaker protection element.High-precision, accurate digital power meter with 40-point LED and 5-digit numeric display.Real-time calculation of resistance between speaker terminals based on output current and voltage to detect short-circuit conditions.When a short circuit or abnormal temperature is detected between the speaker terminals, the meter lamp blinks to warn the user of the abnormality and immediately cuts off the output to protect the speaker.

Buyer cannot choose the shipping carrier. Economy shipping does not include a tracking number. Economy shipping is 11 to 23 days from ship date to arrival. Standard shipping is 5 to 10 days from ship date to arrival. Expedited shipping is 1 to 4 days from ship date to arrival.International Buyers - Please Note: Import duties, taxes, and charges are not included in the item price or shipping cost. These charges are the buyer's responsibility. Please check with your country's customs office to determine what these additional costs will be prior to bidding or buying. Note on voltage:With the exception of some devices such as USB power supplies, most Japanese electronic devices have a voltage of 100V and an "A" plug adapter. In order for you to use this device outside Japan where the voltage is higher than 100V such as 200V-240V, you are required to use a transformer to adjust the voltage to your local country. Without using a transformer and plug adaptor, this device may be broken. Please purchase these devices in your local store.Products with low power consumption can operate at 120V in the U.S. and other countries without problems.
