1.5 Quick Start

Suggested connection is shown in figure 1-3. Before using products, please make sure correct connection.

FIGURE 1-3 CONNECTION SCHEMATIC

Note: Please observe the following steps to complete verification so as to ensure the products are intact during transit.

1. Open the amplifier package and make sure the product is intact (No missing or damaged components and no deformation.

2. Please observe the connection schematics when connecting the amplifier board. Use a nearby sound source, such as MP3 or CD player to have a trial. This amplifier board can be deemed as qualified if you can hear the sound corresponding to that sound source

3. It’s suggested to make sure the polarity of the wires first and then connect the audio cables, wires. Turn down the output to the lowest and then power the board.



Sure Electronics 8


USER’S GUIDE

Chapter 2. Hardware Detail

2.1 Power Connection

To power amplifier boards, kinds of power solutions have been provided.

Both DC jack and terminal blocks have been used. Please pay attention to the polarity when connecting power supply.

Note:

1. You are allowed to use only one way to power the amplifier board at a time.

2. AWG16 wires are recommended when boards are powered by using terminal blocks. The length of power supply cable must be minimized. Increasing length of PSU cable is equal to increasing the distortion for the amplifier at high output levels and low frequencies.

2.2 Input Connections

To meet different requirements, kinds of signal input solutions have been provided - RCA connectors, 3.5mm jack, terminal blocks, optical, coaxial, Bluetooth wireless, etc.

Note: You are allowed to feed only one signal to each pair of stereo channels at a time.

2.3 LED Indicators

Most amplifiers have 1 or 2 power LED indicators – green and red.

Green LED is used on most boards for indicating power-on or power-off.

Red LED is used for indicating good or failure operating.

2.4 Gain Setting

On-board DIP switches or buttons are provided for gain setting on some amplifier boards. For details, please refer to Chapter 3.

2.5 Output Connections

To meet different requirements, kinds of signal input solutions have been provided - banana connectors, 3.5mm jack or terminal blocks, etc.

Note:

1. Never connect more than one group of speaker to each of the audio output

2. Refer to on-board descriptions for connection details.

3. Both positive and negative speaker outputs are floating and may not be connected to ground (e.g., through an oscilloscope).

2.6 Notes

In order to protect amplifier board and extend its service lifetime, please read the following warnings carefully since warranties will be voided if you do not observe the following warnings:

Warning 1:

Quality-related issues caused by potentiometers installed by buyers.

Warning 2:

In order to achieve a better sound quality, please use stable power supply since a bad or unstable power supply may worsen the sound quality or even cripple the amplifier board.

Warning 3:

Never equip a pre-amplifier to the audio input since the amplifier itself has powerful amplification ability and a high signal input will burn out the amplifier chip.

Warning 4:

In order to protect amplifier and speaker, please turn the volume output to the minimum when hooking up the amplifier and you may readjust the volume when you are sure that the amplifier is functioning properly.

Audio Amplifier Board

IRS2092 Series

1 X 2500 Watt 2 Ohm Class D Audio Amplifier Board – IRS2092

(AA-AB31491)


It integrates high performance IRS2092 and IR MOSFET IRFB4227 supporting single channel audio amplification.

It features self-oscillating half-bridge topology with optional clock synchronization.

It is capable of outputting full range up to 2500W RMS @ 2 Ohm continuously.

It can be bridged with another one for higher output, around 5000W RMS @ 4 Ohm, without external circuitry.

High reliability is ensured due to extensive protection, including overtemperature turn-off, DC offset speaker protection, over current protection over voltage protection.

It utilizes a noiseless fan along with temperature sensors to maintain the amplifier’s target temperature.


It is targeted to high-end / high power sound systems like disco, active speakers, large subwoofers for PA (Professional Audio), high power studio monitors and high power hi-end hi-fi systems.

2.5 Volume Control

We adopt digital volume potentiometer of high-quality in Modesty series which can adjust the volume precisely after long-time use.

You can touch the induction (“+”,”-”) to adjust the volume in Inspiration series.

2.6 LED Indicators

Our products are based on MCU which controls the indicators to display dynamic LED state and make our products more fashionable and attractive. Please refer to table 2-1, 2-2, 2-3 for details.

2.8 Fault Tracing

If the amplifier does not work well, please read the following table:

TABLE 2-3 CORRECTIVE MAINTENANCE

2.7 Infrared remote (Modesty Series)

Situation Solutions

No sound

1. Check if it is connected with the power and confirm that the voltage regulator works well. If not, connect the power according to the schematics.

2. Check if the signal input cable is connected correctly and if there is signal. If not, connect the lines according to the schematic and input the audio signal.

3. Check if the output cable is damaged and if the speaker works or not. If not, change the output cable and the speaker.

4. Check if the LED keeps off or not. If not, restart it and ensure that the LED displays breathing effect in standby. If it still doesn’t work, remove the power and contact us.

Suddenly no sound when the product is working

1. Check if the product has worked for long time or if the audio signal is too high. If it is, turn off the power and turn it on again.

Welcome to use this self-made 2 x 100W Audio Amplifier Starter version.

With appropriate power supply you will get 100W RMS output @ 6ohm speaker from both channels at the same time. Besides, a high performance headphone amplifier is provided at the front panel to achieve flexible switch whenever you want.

There is a stereo analog input in single-ended mode: TOSLINK input in S/PDIF format.

This is also a “smart” amplifier. Thanks to the integrated micro controller, this amp can tell you what she is doing via her breathing “eyes”. She can work in two modes: auto and manual. And she will take great protection of herself.

Some additional functions make this amplifier even more powerful and convenient.

There is a subwoofer output via RCA jack at the rear panel. When this jack is plugged in, the amplifier will cut off the low frequency part of the speaker output and transmit it via the RCA. You can feed this output signal to your own subwoofer amplifier. We strongly recommend (AA-AB31241), IRS (2*1500) to you.

Remote control function is also provided to help you use the amplifier in a much easier way and keep you away from the amp to focus on what you are listening. (Remote controller is a separate purchase)

2*1500W 2ohm Audio Amplifier

( )

The D1500 is a 2-channel amplifier that's ideal for stage monitors, PA systems, and more.

It will provide 1500W RMS per channel of clean power to a 2 ohm load, 750W RMS per channel to 4 ohms.

High reliability is ensured due to extensive protection, including over temperature turn-off,

DC offset speaker protection, over current protection, over voltage protection.

D1500 also features very low distortion,>100 dB. Global feedback system reduces THD and achieves almost load-independent frequency response, even with very low impedance loads and utilizes a noiseless fan along with temperature sensors to maintain the amplifier’s target temperature.

Its efficiency is above 95%. But equally important, only dissipates 5.5W with no signal when in ON mode (around 2W when in stand-by).
