------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------ Upgraded 7-band EQ preamplifier: With independent rich frequency band control (50Hz/125Hz/315Hz/750Hz/2kHz/6kHz/16KHz), T8 can compensate for the deficiencies of the speaker and sound field by adjusting the 7-band high, mid-low range, and change various sound sources. You can also change the timbre and loudness to achieve different sound effects. REAL BALANCED XLR PREAMP: Supporting XLR and RCA inputs and outputs, the T8 can reproduce high-quality audio from amplifiers and active speakers with superior separation, resolution, soundstage, and clean background. It also comes with a balance control that corrects the left and right channels of all outputs and prevents the sound field from shifting from the center position. HiFi warm and sweet tube sound: Adopts classic pluggable Soviet Union 6H1N-BN tube, improves all music-related details, warm and delicate, full and mellow, dynamic and melodious sound. Pluggable socket design for tube rotation and sound shaping. Easy to select and change the sound signature to your liking. Advanced design and attractive appearance: Adopts electrolytic iron plate with excellent shielding performance, and the performance is precisely balanced. The black aluminum alloy chassis with vintage warm tube lights is cool, exquisite and durable, very suitable for audiophiles pursuing HiFi sound.
