【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.
Support MM/MC phono input, multiple input impedance switch (1KΩ/470Ω/220Ω/100Ω/47Ω/22Ω/10Ω), can convert phono signal to line level signal, low noise integrated circuit and high quality components can ensure clear sound. T4 PLUS tube preamplifier meets more HiFi audio needs.
3.5mm AUX input, amplifies low-level audio signals from smartphones, tablets, PCs, MP3s, etc., making it easier to drive amplifiers and active speakers, greatly improving sound quality.
Not only MM/MC phono preamplifiers, but also stereo audio preamplifiers and headphone amplifiers are especially designed for audiophiles pursuing HiFi sound. Note: 1. If you prefer 3.5mm AUX input and use MM/MC phono input, please make sure the AUX cable is unplugged. 2.Stereo RCA and 3.5mm headphone jack can be output at the same time, and the knob also controls the volume of the two outputs at the same time.
3.5mm headphone output and perfect circuit design: The T4 PLUS preamp also incorporates a classic headphone amplifier circuit (2*NE5532), which can easily drive 32-300Ω headphones. Adopts affordable and advanced architecture, including TI TPS5430 + 7205MOS for power management and TL071 + JRC2068 phono preamplifier circuit.
A unique and surprising combination of appearance: the preamp is integrated with retro vacuum tubes and features a VU meter. Pointers dancing in warm light with a strong vintage feel, dynamically decorate your audio system and provide you with different acoustic enjoyment when enjoying HiFi music.
Please note:
