High Sound Quality
Sure Electronics provide very high sound quality at the same time, for sure we don’t just offer low power consumption, without a high sound quality, everything is nothing. We can get less than +/-3dB frequency response at the AUX channel and so do the Bluetooth channel if APT-X enabled. For most Sure Electronics audio amplifiers, we can get about 90dB or more SNR and 0.01% distortion when output 1Watt.
All our kiosk audio amplifier boards have been pre-tested with CE and FCC regulations for EMC and safety standard. It will help your whole system to be complied with certifications more easily.
During the practical kiosk amplifier installation, high up to several tens of minutes will be spent on connection and debugging in last step of assembly and test. The reasons behind potential problems lies on many aspects of operation, such as power pins reverse polarity, the correct multi-channel orders, volume adjustment of each channel, signal channel disconnection caused by the poor contact and so on. In order to solve the problems mentioned above and improve the effective connction and pass rate of test, we take the advantage of different forms of connctors for power connections, speaker connections, signal input connections and potentiometer connections. For example, 2CKTS Molex mini Fit JR vertical headers, 4 CKTS Molex SL vertical headers and 4CKTS/6CKTS JST PH SMT top entry type headers are populated in KAB2 for easy recognizations. Furthermore, we also provide the matched extension cables for different connectors, which are easily made distinguished from each other by different cable colors. We spare no effects in improving the connection and measurement efficiency and saving the cost on installations and debugging.
Low Power Consumption
The standby power is 0.5Watt at 12Volts, and if in need we can provide optional auto shutdown circuit, and which will make standby power down to 0.002W, 2mW.
Flexible Input Configuration
This board supports 4 channel input selection and covers the universal audio players in our daily life,such as mobile devices (RCA), NUC or PC Main boaed (HD AUDIO/ AC97), X-BOX or PS4 (TOSLINK/COAXIAL), and bluetooth port. Only 2 jumpers on board are used to set the input channel conveniently.
Fully Protection, Robust Performance
The amplifier board series employs the TPA3116/8 and TPA3110 form TI as the main chip. Both of them are equipped with overcurrent and overtempture protection, which is able to avoid permanent stressed causd by unproper operation.
Besides of built-in chip protection, ESD and spike protection components used throughout input and output of the amplifier board ensure its robustness and reliablity. And all the available input and output pins are present as molex headers which facilitates mating and prevents accidental mis-mating during assembly.
