Tube Queen AM/FM Radio & Bluetooth Speaker R801W-3DI Large collectible table-model Hi-Fi stereo radio /Bluetooth speaker
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.

Radio use instructio ns 1 Listen to FM broadcasting 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.
2 Listen to medium wave broadcasting Medium Wave antenna Medium Wave antenna Press (Figure 2) ⑲ switch to be in medium wave band, and turn the knob 22 to listen to the radio programs within the range of (Figure 2) ○ 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.
Radio external antenna FM/shortwave outdoor antenna Turn the internal and external switch to external position This machine is provided with exclusive FM / shortwave antenna jack, which can be connected to exclusive FM/shortwave outdoor antenna in order to enhance the indoor reception effect.
AFC Function description (Figure 2) ⑫is FM stereo switch, which is provided with AFC (automatic frequency control) switch. When the radio is affected by environment and temperature, frequency shift phenomenon might occur in the received radio program. In this case, AFC function can improve the quality of reception. When using this function, please note that the switch is turned to FM or FM ST position to accurately receive the radio station, and then switch is turned to FM AFC or FM ST AFC position.
External CD Player or Other Signal Resource Please connect audio signal output of CD or other auxiliary signal resource with 17 through RCA AUX IN port of the rear part of radio on the left (figure 1) ○ wire. When using, please press the key switch at the front panel of the radio 15 , and then turn the function switch to FM/AUX position (figure 2)○ 12 .
Speaker system descriptio n Tone control This machine inherits the design of the traditional radio in the 1960s, and is provided with "bass" and "treble" toning knob. The user may adjust the two knobs according to their own sound quality preferences, in order to achieve the desirable sound quality. Attention: in the power-on state, do not use external loudspeaker, and be sure to turn the loudspeaker switch (Figure 1) ⑤ and ⑨ back to INTERNAL state.
Shell maintenance and use Product maintenance and safety This product uses the shell made of solid wood. We give you the following maintenance recommendations: The vacuum tube is a glass product and easy to be broken. When using, it is careful not to greatly collide with vacuum tube. Do not spill liquid on the vacuum tube during the machine's work and ensure that it is used in a ventilated place. 1. 2.

Radio knowledge ①What is shortwave radio? Many countries in the world use short frequency to perform worldwide broadcast transmission. Shortwave frequency range is usually between 1.6MHz and 30MHz. The radio that can receive the frequency with the range is called shortwave radio. ② What is “shortwave meter wave band”？ In general, we also divide the shortwave frequency into many "meter bands". Each meter band contains a frequency range. For example, the 19M band contains a frequency range from 15.
③ ④ Effect of listening to shortwave programs at different times of the day What language programs can be received by shortwave radios? Shortwave signal propagation is subject to the influence of many factors, such as sunspot activity, atmosphere and earth-ionosphere change. The shortwave propagation effect varies with band, sometime good in the daytime or at night. It is not good to listen to shortwave program during daytime, especially from 10 am to 3 pm.
9 ○ ⑩ How to test the effect of an Must the external antenna be very high and long? external antenna? In a general listening environment, turn the radio to a relatively weak shortwave radio station, and go outside of the room while listening. If the shortwave radio signal is enhanced, outdoor antenna should be installed to improve the receiving effect.
14 ○ How to reduce the interference of 16 ○ FM? Shortwave radio Shorten the lever, change the direction of the antenna, change the listening position, and keep away from personal computer equipment, to reduce the degree of interference. Shortwave is transmitted mainly relying on the reflection and refraction between ionosphere and the ground, regardless of day and night. Shortwave can be transmitted very far, so the radio can listen to the long-range radio sound in shortwave band.
19 ○ Why more radio stations received at night than that of the daytime? Medium wave propagation mainly relies on the ground wave. Only a small amount of medium wave is transmitted by relying on sky wave. When a radio wave encounters conductor, conductor will generate induced current, consuming a portion of energy. The phenomenon that weakens the radio wave energy is called the absorption of radio wave. The ground is a conductor, which has high absorption of medium wave.
FCC Warning: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
