01 / BRICK

The Sure Electronics Brick Series combines a high performance Class-D amplifier available in eighteen modules delivering from 300W to 2000W of high-quality audio output power with wide power range. They are in strict accordance with industrial amplifier standard, creating a compact (only 3.9 x 3.9 inches PCB size), indurative amplifier solution in an ultra compact and lightweight package.
All Brick modules are based on Class-T (a branch from Tripath Class-D) modulator, and provide very warm and powerful sound. Sure Electronics always chooses IRF (now Infineon), Infineon, and other world grade MOSFET suppliers, we use only Nippon Chemi Corpration electron capacitors, original SAGAMI inductors in this series and all other components from original manufacturers or authorized distributors only.*

Thanks for Audio Signal Detection and Single Ended/ Differential signal configurable technologies which provide a convenient way to integrate Brick into systems. Not only for industrial integration, Sure Electronics also provides interface boards which are convenient with retail customers.

*Sure Electronics confirms Nippon Chemi Corpration electron capacitors and original SAGAMI inductors are used in Brick series. Other series product materials are selected according to actual situation.

02 / T-AMP

Designed to meet the needs of highly demanding professional audio applications, the T-AMP series emphasized high reliability when developed. All audio amplifier boards have been pre-tested with CE and FCC regulations for EMC and safety standard which will help the whole system to be complied with certifications more easily. Full protections on board like undervoltage, undercurrent, overvoltage and overcurrent protections make the whole system more safe and durable. Reverse connect protection on board will save huge maintenance costs and time for system integrated customers. Temperature control fan with a high quality customized heatsink provides reliable double thermal protection.

High Sound Quality

Sure Electronics build this product series for high quality sound. This product series is driven by Class-T (a branch from Tripath Class-D) modulator, and provides very warm and powerful sound. We are not going to waste words in what Tripath chips can provide. There are too many such articles. We are just                            sure that we are the most skilled designers for Tripath chips. Original and most                            powerful integrated power stage STA516BE from ST Micro, which is the direct                            cousin from Tripath TP2050, just more powerful, is used in our integrated                            solutions. We fine select very low RDSon MOSFETs and they must be audio                            suitable in our test, extremely fast recovery diodes, in our discrete power                            stage. That makes our auido amplifer boards able to provide best high sound                            quality for listening, not only in datasheet.

Single (Asymetric) Power Supply

This product series requires single supply ONLY. You don't have to use transformers. Only one switching power supply unit is enough and we even do not need any auxialiary power supply. That will greatly reduce the installation time and the system design is never complex. Sure Electronics also provides a                            Farad Capacitor solution, which can ensure customer use 350Watts - 600Watts                            Power Supply Unit to drive 1kW rated audio load. Contact us for details if you                            are designers for subwoofers, it will reduce your cost greatly, not by using a fake                            power marking trick.

03 / TAS5630B

Just one look at the power input terminals and you will know that this amplifier board means business! A Class-D Texas Instruments TAS5630 with PurePath™ HD enabled integrated feedback is used to deliver 300W to two channels, effortlessly and efficiently. This amplifier board works amazingly well with both low sensitivity speakers and subwoofers.

A robust heatsink, two-stage cooling fan, as well as protection circuits to protect against over/under voltage, over current, short circuit, and over temperature conditions are built-in for years of enjoyment. Four fixed gain settings allow you to match the amplifier to your source, and use your source as the volume control. A 25 to 50 VDC power supply is required (sold separately).

  •   Class-D Texas Instruments TAS5630 with PurePath™ HD enabled integrated feedback
  •   Robust heatsink with two-stage cooling fan
  •   Pre-drilled mounting holes
  •   Over/under voltage, over current, short circuit, and over temperature protection circuits
  •   Click and pop noise reduction
  •   Phoenix-type speaker terminals
  •   Two line-level RCA inputs
  •   Large screw-down power input terminals

    *Introduced here is 2x300W TAS5630 Class-D Amplifier Board (AA-AB32191).

04 / IR2092

This Class-D amplifier board uses an Internal Rectifier IRS2092 amplifier controller IC, six IRFB4227 HEXFET® power MOSFETs, and two ST Electronics STTH1602C high frequency, ultra-fast diode ICs to deliver amazing amounts of clean output—up to 2,500 watts x 1—into a 2-ohm load.
Two 60 to 94 VDC high-voltage power supplies are required for operation; each power supply dedicates its full output potential to a single rail for maximum output. This results in increased high-fidelity output, high dynamic range, low distortion, and a wide 20 to 22,000 Hz frequency response.
This amplifier board also includes a myriad of protection features: over current, over/under voltage, DC output, and temperature protection circuits are built-in. A rather small footprint lends itself for use in space limited applications.

Real Strength for Any Applications

In Sure Electronics, that is real 1kW when it is declared as 1kW; that is continous playing back for 1kW audio signal; that is continous power for drive 1kW resistor dummy load; that is continous power for drive 2550Watts air conditioner in parrallel! That is different, different from those weak amplifiers with only coin size                            heatsink, different from those amplifiers without good layout and traces thin as                            hair, different from those amplifiers without any high quality components. How                            could they achieve the rated power they declared? So try Sure Electronics                            amplifiers and feel what true RMS power means.

Great Components from Great Suppliers

We always use IRF(now Infineon), Infineon, and other world grade MOSFET suppliers. We use only Nippon Chemi Corporation electron capacitors, original SAGAMI inductors in this series and all other components from original manufactuers or authorized distributors only. We can always provide commecial                            invoices from our suppliers - only original or authorized.

*Introduced here is 1x2500W Class D IRS2092 Amplifier Board (AA-AB31491).
