Tube Queen AM/FM Radio & Bluetooth Speaker

Product Introducti on
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) ⑩is 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) ⑪is 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) ⑬is 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.

Front panel (Figure 2) ⑮- ⑲five key
switches are function and wave

the radio will start working under the
corresponding function or wave.
(Figure 2) ⑯-⑲when a certain wave switch is pressed,
adjust the tuning button, (Figure 2) ○
22 to search for
your favorite radio station. When the "cat’s eye" (Figure

reached the optimal state.

Radio use instructio ns
1
When the machine is used as a radio, it is of paramount
importance to place the machine and the external antenna
correctly. Otherwise, you may not receive any radio programs,
or only receive bad one! It is recommended to use the machine
close to window as much as possible. If it is impossible to use
the machine near the window, a group of external antennas will
be of great importance. The more professional the antenna and
antenna installation, the better the machine performance. In
addition, in case of connection with external antenna or not, it
should also be noted that the switch position for “internal/
external” antenna on the back of the machine must be correct!
Listen to FM broadcasting
This machine has equipped with built-in FM line. If the radio is placed
close to the window in the general urban area (not far from the radio
transmitting station), there is no need to use external antenna
generally. When external antenna (random accessory) is used, turn the
rear③(Figure 1) to the external (EXTERNAL) position. The external
antenna of this machine can also be connected with dedicated external
antenna or dedicated cable antenna. Press the (Figure 2) ⑯key switch
on the front of the machine to be in FM wave, and adjust the tuning
knob to the range of 87--108MHZ for its radio programs. Turn the
transfer switch (Figure 2) ⑫to FM position to be in ordinary FM state.
Turn to FM St position to be in stereo FM state. If the FM St effect is
not good enough, the switch can get a higher Signal to Noise Ratio
(SNR) at FM

Listen to medium wave broadcasting
Press (Figure 2) ⑲switch to be in medium wave band, and turn the knob
(Figure 2) ○
22 to listen to the radio programs within the range of
530-1610KHZ. This series of machine has high magnetic antenna. The AM
external antenna can also be used. Connect the two lines of the antenna to the
antenna clip, as shown in the figure below. Adjust the antenna to the best
direction, and then adjust the knob on the antenna (with external antenna for
tuning) to get the best signal. When the outdoor antenna is used, make
connection from (Figure 1) ①, and adjust the direction of external antenna to
get the clearest radio broadcasting.

Listen toAM shortwave broadcasting
The shortwave shared FM antenna (using external telescopic antenna for best effect) is
used as same as FM. This machine has shortwave 1 and shortwave 2. Press the front
keyboard switch ⑱to be in shortwave 1 , press the front keyboard switch ⑰to be in
shortwave 2, and adjust the tuning knob ○
22 to find the desired radio broadcasting. In
shortwave 1, the radio programs within the range of 4.5-12MHZ can be received
(Figure 2). In shortwave 2, the radio programs within the range of 12-24MHZ can be
received. When the radio broadcasting is received, please turn the short or long distance
switch ④on back of the machine to LONG-DISTANCE position. When the machine
is close to the station with strong signal, please turn the short or long distance switch to
the SHORT-RANGE position. Otherwise, it may cause overload . The (Figure 2)
"fine-tuning knob" may also be adjusted for fine-tuning in order to receive program in
the best state. The factory status is "remote".
