Product Description
Introduction to 768 remote control balanced tube preamplifier:
●The panel is made of aluminum alloy wire drawing process. The chassis is made of 1mm thin steel plate, with good shielding effect and frosted paint process.
●Metal film resistors and military Dahongpao resistors, Siemens Thousand Layer Cake and other capacitor coupling are used.
●The 4-way input is switched by imported silver contact relays, which has a longer life and smaller contact resistance.
●The input and output interfaces use gold-plated lotus seats.
●The power transformer uses a ring transformer, imported iron core, oxygen-free copper wire winding, and sufficient power supply.
●Standard version: 6J1 or 6C1 vacuum tubes * 4 are used for amplification.
●The remote control can achieve: volume, channel switching, and mute functions.
●The volume uses the original Japanese ALPS motor potentiometer.
●With a power grid purification circuit.
●There is a headphone monitoring amplifier output.
●The volume knob uses an expensive aluminum alloy knob.
●The machine has a memory function, which remembers the channel status when it was last turned off.
●When the device is turned on, the channel status window flashes to remind you that it is preheating. After preheating is completed, it turns on and displays the current channel.
●Press the mute button on the remote control, the channel status flashes, press it again to resume, or press the volume up and down buttons to resume playback.
●Bluetooth is optional, using the Qualcomm CSR8675 receiving module and PCM5102A decoding. Copy the lossless audio file to your phone, download and install the HiBy Music APP to play, and you can get close to CD quality.
