New product---Alctron SD series DI box


2018 new year new start. Alctron publish the newSD series DI box (impedance transformer), totally 3 kinds, they are SD201SD202SD205. Alctron hasalready had DB-1DI100DI120 and other kinds of impedance transformer. Compared with regular DIbox, new DI box is pay more attention to appearance and color. Otherwise,making some changes in function, the transform function is more outstanding.

Feature 1: multi-color, easy to distin

Alctron found that nowadays there is a commonproblem in living stage: when many amps put in together, you may confuse. Baseon this point, when D & R SD series DI box, Alctron choose highestrecognition color, red, yellow and blue. After choosing color, we make sometoning, then the color is more beautiful.

It is easy to recognize, even in a complexlighting environment, you can see it immediately.

Feature 2: applying to various acoustic environments

Different acoustic environments ask fordifferent DI box. So Alctron D & R one series DI box to fitting differentacoustic.


In SD series, SD201 is an active DI box andSD202, SD205 are passive DI box. Take its function as example, SD 201 applyingto bass, keyboard, acoustic guitar and other instruments, especially when theoutput level is lower, it also keeping outstanding sound quality..

SD202 focus on high Z instrument helping them toreduce its own impedance. SD202 feature two transformers to balance the signal.MONO output connector used to transfer stereo to mono signal. SD205 designedfor laptop, tablet, smart phone and other music player such devices without anypower supply.

SD series DI box adopts high quality alum shellwhich is firm and strong impact resistance. The concise designing style andspace-saving volume make it easy to carry out. Though dust-free paintingprocessing to roast and paint, then the surface is fine and smooth. Theconnector is also showed ingenuity.
