Product
Introducti
Tube Queen is a large table-model radio /Bluetooth speaker produced by our company.
This product uses the Hi-Fi concept and draws experience from Germany's excellent
radio design style in the 1950s to 60s. The product uses electronic tube to make power
amplifier and signal strength received indicator.
This product is a high-sensitivity radio with FM stereo reception and high-quality
Bluetooth speaker, but also a Hi-Fi tube amplifier that may be used separately. In case of
connection with external high-quality speaker, it can form a set of high-fidelity stereo
system.
This product is a multi-frequency radio that has four frequencies, namely, FM (FM)
stereo, medium wave (MW), shortwave 1 (SW1) and shortwave 2 (SW2), and uses
vacuum tube (commonly known as "cat’s eye") tuning indicator.
This product is also a high-quality Bluetooth audio speaker. Its Bluetooth program uses
the CSR 4.0 Bluetooth module that supports aptx lossless transmission. Hence, it can
guarantee excellent audio effect via Bluetooth.
This product uses high-power vacuum tube to make post amplification, so the output
power is strong. Coupled with the high-quality loudspeaker, and excellent circuit and
electro-acoustic design, this product has acquired sound effect unique to radio set. In
connection with stand-alone high-quality audio speaker, the Hi-Fi sound effect can be
achieved.

Power switch and sound adjustment
(Figure 1) ⑩ is the powerport (in), which may be
connected with 230V or 115V alternating current
(AC) by use of standard three-pin plug (random
configuration). Before use, please check if the
voltage transfer switch (Figure 1) ⑪ is consistent
with the alternating current (AC). When the voltage
transfer switch is at 115V position, it can adapt to
110 - 120V/60HZ alternating current (AC); when the
voltage is at 230V position, it can adapt to
220-240V/50HZ alternating current (AC); the
switch’s factory setting is 230V (Note: only adjust
under professional guidance)
Panel (Figure 2) ⑬ is the power switch and
volume knob. By clockwise rotation, turn
the power on, and by counterclockwise
rotation, turn the power off. After power
on, continue to rotate to the right to
increase the volume to an appropriate
location (the volume knob is normally
adjusted to around ten o'clock direction).
Due to the use of vacuum tube amplifier,
vacuum tube needs about 30 seconds for
warming up before normal operation.
Therefore, the radio speaker will make a
sound 30 seconds later. Note that the
volume can’t be turned to the maximum
during these moments.
