ALO, LR independent portable DAC/amplifier "Continental Dual Mono"

　The Mixed Wave will release a Portable USB DAC/amplifier "Continental Dual Mono" with ALO AUDIO, which has a vacuum tube independently.The price is open price, and the expected price is around 195,000 yen.There are two colors, black and silver.

　Portable DAC/amplifier with Micro USB and analog input/output.Analog input / output is 3.In addition to 5mm stereo mini, 2.5mm 4極端子も装備。Astell&Kernシリーズの対応プレーヤーとバランス接続できる。

　The amplification stage is a dual mono configuration with two built -in vacuum tubes.Equipped with an independent linear voltage regulator for each circuit, the internal voltage of each circuit is independent.It is said that the distortion of the internal voltage was minimized by the amplifier circuit and the DAC circuit.In addition, a clean power supply with less distortion is delivered to each circuit by a linear -type voltage regulator without switching noise.

　The built -in vacuum tube is a Philips "6111", which is sold to a customized PCB, making it a microponic noise measure, making it easy to replace it by users.At a later date, a vacuum tube for replacement will be released.The motorcycle system (self -bias system) is adopted, and the vacuum tube bias adjustment is not required.

　The cross talk is suppressed by the amplifier design that makes LR independent.It has a built -in transistor as well as a vacuum tube, and it is said that it is an ALO AUDIO's unique sound stage with a rich midrange of the vacuum tube, pursuing low impedance, tight bass, and accurate acoustic characteristics.The IC amplifier adopts parts that meet the Alo Audio standard and layout class AB.

　The DAC chip is equipped with WOLFSON's "WM8741A" and DSD 2.Supports 192kHz/24bit such as 8MHz and PCM.The housing uses an aluminum with CNC processed.A heat dissipation hole is provided on the side.Gorilla glass is used for the front window where the interior vacuum tube is seen.

　Panasonic lithium -ion battery "18650" with a life expectancy of about 1,000 cycles is implemented in series.Continuous use time is about 7 hours when only unbalanced output is used, and about 5 DAC or balance output is used..5 hours.It depends on the type of vacuum tube used.The charging time is 3 hours.

　It also has a gain switching switch and an indicator that can determine the sampling rate when digital input.The external dimensions are 82 x 127 x 25mm (width x depth x height) and weighs about 412g.Includes silicone straps and AC adapters.

　Sold separately, connect the product with the AK series "AK380", "AK240", "AK120LL", and "AK100LL", 2.5mm/4 polar cable "SXC 24-2.5mm to 2.5mm Balanced "will also be released on July 29.The price is open price, and the expected price is around 13,900 yen.Length is 10.8cm.Use 4 high -pure silver plating copper 24 AWG conductors.The exterior material is LUX FEP (fluorided ethralopylene).
