FX AUDIO TUBE-03J + Vacuum Tube Hybrid Preamp Tone Control Black Description Op Amp & Vacuum Tube Hybrid Preamp "Adopting 6K4 as a Standard Accommodated Vacuum Tube, HIGH / LOW" "" Tone Control Function (Tone Direct Function) "Power Supply Active Filter Circuit with Power Transistor" "AC Adapter Required (Sold out) DC12V / 1A DC Jack 5.5mm × 2.1mm (Center Plus) " This product is a hybrid type preamplifier combining a vacuum tube and an op amp. By adjusting the volume and sound quality by the operational amplifier arranged in the previous stage, the tube and the advantages of the operational amplifier are added by using the tube tube of the subsequent stage, and the tone of the vacuum tube is unpleasant even at the maximum volume of the volume. I can enjoy it. In addition, while introducing high quality parts with a well-established high quality part everywhere so as to use in full-scale audio applications, we have realized a price that is easy to obtain at low prices. [How to use] Please use this product between the output of the sound source playback device such as a CD player, a DAC, and a silicide player, and a power amplifier. INPUT: Connect to analog output terminals such as a CD player or DAC. Output: Connect to an analog input terminal such as a power amplifier main amplifier. [Features of Products] ■ Adopting 6K4 as a standard attached vacuum tube TUBE-03J adopted a 6J1 military tube in the supplied vacuum tube, but it is already difficult to obtain 6J1, so with TUBE-03J +, 6K4 is used in TUBE-03J + Is. The design itself is done on a 6J1 basis and is adjusted to no problem with 6K4, but we recommend 6J1 (sold separately) to taste the original power. It is not the difference between 6K4 is not good, so it is one of the fun of TUBE-03J + to try a delicious vacuum tube. ■ Hybrid preamp by vacuum tube and op amp The pre-stage buffer unit and tone control unit adopt TEXAS INSTRUMENTS audio operational amplifier "NE5532" (DIP socket type) with high cost performance on the sound quality surface! The later stage is a hybrid configuration of a vacuum tube circuit, and the sound quality with high quality and depth and taste by utilizing the adoption of the vacuum tube and the op amp respectively. ■ Tone control function (tone direct function) ■ Gain setting function The DIP switch on the back of the main body can set a two-stage gain setting of HIGH / LOW. ■ Equipped with power supply active filter circuit by power transistor ■ Recommended part of adopted parts ■ Improve characteristics by reviewing artwork ■ DC 12V also fully driven and noise measures by boosting [Notes] ※ AC adapter is sold separately. Please purchase the recommended AC adapter at the same time. ※ This unit is a preamp. Power amplifiers are required separately to connect to passive type speakers (not built-in amplifier).
