Hi , can the wondom JAB5 amplifier handle 4 ohms?

Hi.

It is suggested to use JAB5 to drive a 6Ohm load.

It may cause over current protection if JAB5 is used to drive a 4Ohm load.

Wish this could help you.

Does the AA-JA33286 have 4 analog inputs? If not, how would it function as a 4.0 amp? Thank you.

Hi.

Thank you for your interest in our products.

AA-JA32286 doesn't have 4 analog inputs. It supports analog input, Bluetooth input and I2S input. All the signals would be mixed and then be divided by ADAU1701 DSP and transmitted into four amplifier chips for amplification. Please see the attached block diagram for reference.

You can change the settings through programming the firmware with SigmaStudio.

Wish this could help you.

Thank you for your answer for my queston "After downloading data from SigmaStudio to my JAB3+ board (SKUAA-JA32173) via ICP3 programmer the bluetooth connection interupts and cannot be restored", but the problem still remains. After using SigmaStudio to upload any kind of program, the connection via bluetooth is still possible but no sound played back.

Hi.

If possible, could you take a video to show us how you restore the program and the Bluetooth problem so that we can find the reason and solve it for you?

You can send it to store@sure-electronics.com.

We will reply to you as soon as we receive your email.

Is there a sound or beep when bluetooth is connecting? - Most Amps or bluetooth adapter do that noise/beep, when connecting.

Hi.

There is no sound or beep when Bluetooth is connected.

There is an indicator for Bluetooth. When the Bluetooth is searching, the indicator will blink. When the Bluetooth is connected, the indicator will be ON.

Wish this could help you.

Hi, I would like to control the volume of the AA-AB3225-6 (TAS5754 based) board from a touch screen using an Arduino or ESP32 based microcontroller. Are there any code examples (preferably using the Wire library) on programmatically changing the volume that I can adapt? Thanks.

Hi.

The AA-AB32255 (6) has already been integrated with MCU 5754 controller and the communication terminals are not drawn out. You can control the volume potentiometer port through high-low voltage level to adjust the volume.

Wish this could help you.

Hi, my amplifier (AA-AB31241) is in shutdown when I start it. SHDN pin is floating (5V) on the board, and output is not short circuit. How can I remove this SD mode ? Thx for your help !

Hi.

Could you please check if the output voltage of the audio amplifier is approximately half of the power supply?

Here is a video for your reference on how to locate the problems of the audio system.

I have 100 WATT CLASS D AUDIO AMPLIFIER BOARD WITH BLUETOOTH - JAB2 - 1100[743] It replaced a basic TPA3116d2 in a very high efficiency setup. On Bluetooth the volume is way low compared to how it was with the previous amp. Is there a way to increase the gain? It is not even touching the speakers capabilities.

Hello.

The gain of this board is 26dB now.

If you want to increase the gain, you need to replace the corresponding resistors on the board.

Please see the resistance value needed for different gain and the position of the two resistors in the attached pictures.

Wish this could help you.

Hello, is the new (JAB5 4 X 100 WATT CLASS D AUDIO AMPLIFIER BOARD SYSTEM[756]) compatible with the (5S 26650 LITHIUM BATTERY BOARD)? If so, how would the wiring look like? Thank you in advance.

Hi.

The new JAB5 can be powered by BCPB4.

Since the output voltage of BCPB4 is 21V max, the output power of JAB5 would be lower.

Please kindly see the attached picture for reference: Connect the output port on BCPB4 with the power supply port on JAB5 pin to pin.

We will release a BCPB-BSH very soon, which can boost the voltage of the battery board to DC24V/32V/36V/48V.

Please stay tuned.

Wish this could help you.

Hi, hope you can help. I have a new AA-AB31511 with the AA-AA11117 volume control. I am running it from 2 laptop power supplies in series to give 39v dc. All I get out is a single continuous tone about 400hz. Does this with or without any input. What way round does the volume control go? What are the switch settings? Are there any other jumpers/links? Any other suggestions?

Hi.

It is suggested to change a power supply and have a try.

Please check the operation voltage of the amplifier board after powered on to see if the amplifier has been powered on successfully and if the output voltage is around half of the power supply voltage.

Here is the video for your reference.

In addition, please try to use a separate audio source to input audio to avoid the ground loop issues.

Hello, are there hardware filters on the output of the JA31181? Can I listen to normal music using a standalone JA31181?

Hello.

Thank you for your interest in our products.

There is hardware filter on the output of AA-JA31181. In addition, there is a default program in the equipped DSP module, which includes filter.

There are also four on-board potentiometers on JAB3, through which, you can adjust the frequency and gain. You can refer to the datasheet for detailed information.

You can play music with the standard JAB3.

Wish this could help you.

Hello, the JAB3+ seems to be a very interesting product of its class, could you answer these questiones for me? Is the mudule capable to connect itself to another one? For example using two of them as mono speakers and connect them wirelessly to create a stereo setup? (like commercial bt-speakers JBL, sony...). Can I config the module with my ICP1 programmer kit? kind regards

Hello.

Thank you for your interest in JAB3+.

JAB3+ do not support TWS for wireless audio connection with another JAB3+.

It provides an analog signal output, which can be connected with another standard audio amplifier to build audio 2.1 or 4.0 system.

We are now preparing to develop new products that supports TWS.

With the ICP1, you can program JAB3+ with SigmaStudio.

Wish this could help you.

I added additional cells to create 2 x 72v battery packs for my AA-AB32431 but it's still not working. The fans spin up for a few seconds but nothing happens after that. These are 20amp lead acid batteries, with 16 gauge wiring. What am I doing wrong? The only thing I can see is I'm not using the grounding cable, not sure if it's necessary. Please help! Please email me andycaldwell@yahoo.com

Hi.

It might be the connection problem.

We have uploaded a connection diagram for your reference.

If there is still problem, please send a picture or a video to store@sure-electronics.com so that we can find the problem and solve it for you.

AA-AB32431 I just purchased this amplifier for a battery powered portable speaker system I'm building. I'm using 2 x 36v. 20ah Lead Acid batteries as the power supply. However, when I connect the amp to the batteries, nothing happens. What am I doing wrong?

Hi.

Please note that IRS2092 series boards needs dual power supply.

The recommended power supply range for AA-AB32431 is ±55 - ±75V.

You can take the following video for reference:
