DAB is the third generation broadcasting after conventional AM, FM analog broadcasting .DAB is short for Digital Audio Broadcasting, which is close to CD quality sound, and the listener can listen to the radio non-interference completely.
The tube FM radio used tube 6N3 as a high-level and mixing, tube 6C11 as the unit local oscillates,tube 6J4 as IF amplification together with 5pcs mid cycle inductances, and it has the advantages of high sensitivity, low noise. After stereo decoded by TA7343AP, then the signal will be amplified by tube 6N2 as a preamplifier. And power amplifier part, it used 6N2 to drive 2pcs tube 6P1 that is classic and famous application.
This tube radio has two tubes, which adopt super-regenerative mode to receive FM radio signals. Has high sensitivity, Either high impedance headphones with nostalgia, but also through the line output jack. You may connect it to amplifier and computer sound card to access the playback, that expand the scope of application of the radio.
This tube FM radio head adopted tube 6C11, and its rectifier adopted tube 6Z4. Its signal reception and treatment adopted classical tube circuit, and used TA7343 as a stereo decoder that then result in stereo output. After stereo FM signal input power amplifier system for amplification, you will listen to FM radio with musical tube sound
Gennally, a HIFI interconnection RCA cable is made of 2 pcs pure copper RCA connecters which are made of copper-plated plug generally, copper shell, and advantages of copper shell can be shielded from external interference and a pair separated OFC wires cable instead of a pair of wires molded together, and then assemble them though soldering with high quality solder.
Tube amplifer combines wireless Bluetooth technology is new trend, especially, combines the latest Bluetooth 4.2 like as CSRA64215 that also supports aptX audio technology that provides CD-level sound quality with Bluetooth connectivity
A typical setup for a USB DAC system is shown above. We have two Firewire disks for our library (one is for backup). We use Firewire over USB drives because we don't want to overload the USB link. The output of the DAC is fed to a preamplifier or integrated amplifier and then to the amp and speakers.
Single-ended tube output circuits are used in both audio and instrument amplification. There is less distortion in a single-ended amplifier because the output currents do not cross over.
Users often consult our technicians, how to deal with left and right channels imbalance? This is a bit of a relatively complex issue, involving audio sourcing, audio cables, amplifier, HIFI speakers as well as factors such as personal subjective listening. Without considering the individual factors of subjective listening conditions, you can solve it step by step with the following tips.
