DESHIBO RD1748 Full Band Radio Second Frequency Conversion High Performance Professional Digital Tuning Radio

DESHIBO RD1748 Full Band Radio Second Frequency Conversion High Performance Professional Digital Tuning Radio

Features:
- RD1748 is a high-performance broadcasting receiver designed to cater to broadcasting enthusiasts.
- The panel adopts a hot stamping and wire drawing process.
- This machine uses a high-performance microprocessor (MCU) to accurately control the radio frequency, automatically track and lock the received frequency, overcoming the frequency drift phenomenon existing in traditional analog radios. At the same time, it can display status information such as radio frequency, time, and broadcast signal strength.
- Use a powerful microprocessor to set intelligent alarm mode, snooze mode, and timed sleep mode.
- The use of secondary frequency conversion technology greatly improves the sensitivity, selectivity, and anti-interference of radio receivers.
- Equipped with a 75Ω FM antenna socket, it can easily connect to FM dedicated outdoor antennas for FM long-distance reception (FM DX) or connect to local wired broadcasting networks (75Ω CABLE FM).
- The short wave of this machine adopts a field effect transistor (FET) as a preamplifier, which is stable and reliable.
- Medium wave/short wave can adjust the RF GAIN based on the strength of the broadcast signal to achieve the best reception effect.
- The medium wave can choose a wide/narrow medium frequency bandwidth, greatly improving listening performance.
- In order to suppress the interference of various powerful FM radio stations and VHF communication signals near the listening location on shortwave reception, a RF low-pass filter (30MHz LPF) was designed on the antenna circuit.
- Equipped with 500Ω external antenna port in the mid band
- Unique software algorithm design for fast and slow tuning selection, capable of quickly and accurately selecting channels
- Favorite 50 radio stations memory function.
- To achieve the best sound reproduction, this machine adopts a 5-inch high-quality speaker and AB class analog audio amplifier integrated circuit, and is equipped with independent high and low pitch adjustment circuits.
- When receiving FM radio, using headphones to output can listen to FM stereo. Users can manually turn on and off FM stereo according to the radio program to obtain clearer and purer sound.
- Equipped with an L/R line output socket to connect to audio amplifiers and recording equipment.
- Equipped with an L/R line input socket to connect an external sound source as a power amplifier.
- The LCD display screen of this machine adopts a white night backlight lighting system, which can be manually selected to turn off or automatically turn off the light in 3 seconds.
- This device is easy to carry and can be used for both carrying on shoulder and hands.
