Product Introduction:
1.Power Supply Voltage:defaults double AC 18V/3A,power more than 60W (the maximum voltage should
be no more than double AC 19V,and it should be no less than 18V;or the digital tube will be off,
and the voice will get distorted;if you want to use AC 12V,you need to modify lamp filament buck
resistance 2.2 ohm;then the amplifier output power will be relatively low).
2.Headphone amplifier/pre-output:amplification times is 0.8
3.Im1875t amplifier output power:typical 20W (max 30W)
4.Loudspeaker impedance:4-8 ohm
5.Total harmonic distortion:<0.04%
6.Signal noise ratio:105dB
7.Frequency response:14Hz-100KHz

3. Rotary encoder can count the output
pulse times by rotating positively and negatively. This counting method
has no limitation,it can reset and come back to the
initial status if matching with the key on the encoder (that is to say
it will count from 0).
4. Operating Principle: Incremental encoder is a kind of rotary sensor which transforms the rotation displacement into a series of digital pulse signal. These pulses are used to control angular displacement. In Eltra encoder, the transformation of angular displacement adopts photoelectric scaning principle. The reading system is based on the radial dividing plate's rotation of alternative light window and non-light window, and it will be exposed to infrared light source at the same time.
The light will reflect the picture of plate on the surface of receiver. The receiver is covered by a diffraction grating, and it has the same window width with the plate. The operation of receiver is to detect the change of light plate rotation, then transform the light change into
electric change. Increase the low level signal into high level and
generate square pulse without any interference. This process needs circuit to deal with. The reading system usually adopts differential method, that is compare two different signals who have the same waveform bu the phase difference is 180 degree so as to improve the output signal quality and stability.
Reading is formed on the basis of the difference between two signals, so
it eliminates the interference.

Much thanks for your order and joun wwwicstation.com. Here we have this new DIY kits recommendation to you.
Tesla Coil is a transformer (resonant transformer) that uses resonance principle to produce ultra-high voltage but low current, high frequency AC power.The Tesla coil consists of two sets (sometimes three groups) of coupled resonant circuits.
This Tesla added New music playback
function: arc stimulates the air into the plasma, and generates the
vibration of the air which makes this new concept of speaker! This speaker can play mobile phone and computer music with high-quality sound.
When voltage input 15-24V DC, arc length 24V, Tesla Coil 5 - 10mm is the most ideal. Small size woth full-feature, it can work for a long time without interruption, also can light up the lights, energy-saving lamps, flash frequency tube and so on without touch with them.
Attention: 1. This product is safety, as the power is
not high; but you'd better dont touch the electric arc on top of the
coil, there will be burning sense. 2. After a long time of charging, plz do
not touch the heat sink because of the very high temperature; especially
when using 24v voltage.It has a reserved fan interface, plz add cooling
fan if necessary. 3. Plz dont let yourself or other objects
close to the coil when it is working. That is because of other objects,
as a good conductor will make the coil to form a good circuit and absorb
coil energy, which will make the effect terrible. 4. Do not put mobile phones, mp3 and
other electronic devices close to the coil, otherwise the coil will
produce high-frequency magnetic field interference, making your phone,
mp3 and other equipment out of work or even damage!
