How to wire the power supply? There are 4 cables, 2 VCC and 2 GND on the board and the cable that come with the package. Do I use only 1 of these pairs (1 VCC and 1 GND)? Or there is something else

Hi.

You need to short circuit 2 VCC cables before connecting to the positive pole of the power supply.

And also short circuit 2 GND cables before connecting to the negative pole of the power supply.

In this way, it provides higher current for the amplifier board.

There are two versions of ADAU1701 Audio Digital Signal Processor Kernel Board - APM2. One version has micro USB power supply input and another one has USB Type-C.Please explain the difference between these two versions.

Hi.

The difference is the power supply port and communication LED. The old version used micro USB port and the new version uses USB Type-C port, which is equipped with a communication LED.

Hello, I've recently bought a VC01-M62429 volume control unit and after a bit of use I noticed a significant amount of play in the shaft of the rotary encoder and it makes adjusting the volume unpleasant. Could I get a replacement or is that normal?

Hi.

Could you please kindly send some pictures to store@sure-electronics.com so that we can check it for you?

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

hi, i would like to connect via I2S APM2 (slave) & ESP32 (master). should I remove the Y1 oscillator from APM2 and connect the MClK pin of APM2 to MCLK generated by ESP32?

Hi.

Yes. Since your device is master mode and has MCLK, you need to tear down the crystal oscillator on APM2 and connect MCLK pin to MCLK generated by your devcie.

Please kindly refer to this video.

Hello, I am looking to make a 2.1 audio system for two 15watt 4ohm speakers and one 30watt 4ohm subwoofer. Is there way for me to create this with Wondom equipment?

Hello.

It is suggested to use JAB4 (4CH 30W audio amplifier board, which can be configured as 2.1 output mode) or mono JAB3 + stereo JAB2v2.

Since the power is higher than that of your speaker, you need to control the voltage of input signal or control volume to make sure your speaker do not overheat.

Can I combine a JAB3 DSP with 2 other boards to create a 4.1 system, all of which are controlled by the Sigma Studio DSP processing? Thanks!

Hello.

JAB3 can be connect with JAB2v2 to build audio 2.1 or 4.0 system and they can all be controlled by SigmaStudio DSP processing.

If you want 4.1 system, it more suggested to connect JAB4 with 2CH audio amplifier board TAS5754.

Hi, Jaap van Mastrigt.

Thank you for your interest in our products.

JAB3 can be connected with JAB2 as 2.1 system or 4.0 system.

If you'd like to build such an audio system, you can take a look at this video.

https://www.youtube.com/watch?v=uDU5oW40AbM

If you want 4.2 system, it is suggested to connect JAB4 (4CH amp with BT & DSP) with 2CH TAS5754 amp.

Hello, how exactly do I have to connect the ON/OFF switch on the AA-AB32178 to eliminate the crackling noises? Which pins need to be connected? mfg, Nils from Germany

Hi, Nils.

To eliminate power-up pop noise, please do as follows.

First, short circuit 'MUTE' and 'GND', as well as 'STBY' and 'GND'. Then power up. After that, make 'STBY' and 'GND' open at first, after around 500ms, make 'MUTE' and 'GND' open.

To eliminate power-off pop noise, please short circuit 'STBY' and 'GND' before powering off.

HI, Do you have a UK based supplier/stockist. I have ordered from Audiophonics but due to brexit I have incurred higher prices/import taxes and postage time of 3 weeks or more. I would like to be able to order from someone with a more urgent delivery.

Hi.

We don't have supplier in UK.

Maybe you can place an order with us directly and choose express shipping.

It will take around 3-7 days for the parcel to arrive.

Hi, I want to update the firmware of the ICP5, but the software don't recognize the ICP5. The Analog Devices USBi is listed in the device manager of windows. The programming LED is blinking. Miumax JAB2 is installed. Can you help me please?

Hi.

If you want to update the firmware of ICP5, you need to make it turn into BootLoader mode at first.

You can take the introduction on PC UI control in the user guide for a reference.

If the power accidently gets connected backwards will it damage the board 2 X 15WATT CLASS D AUDIO AMPLIFIER BOARD - MAX9736A[145]?

Hi.

This audio amplifier board is integrated with reverse voltage protection.

Therefore, if the power gets connected backwards by accident, this audio amplifier board will enter into protection mode.

Will the 2 X 15WATT CLASS D AUDIO AMPLIFIER BOARD - MAX9736A[145] work with a 12VDC or a 24VDC power supply?

Hi.

Thank you for your interest in our products.

The recommended power supply range is DC10V - 28V

Therefore, this amplifier board can work with a 12VDC or a DC24V power supply.

The output power would be only 9W when it is driven by a 12V power supply in an 8Ohm load.

Is there a way to allow the I2S input and output to operate at the same time while the JAB5 is still in master, sending the LRCLK and BCLK to another device (like an RPi) with data in and out? I noticed in the documentation it says that it is either in or out, but I would like to use both while it is set to master.

Hi.

Thank you for your feedback.

JAB5 has been defined as when it's master mode, it supports I2S output and when it's slave mode, it supports I2S input, which cannot be changed.

If you want I2S input and output simultaneously, please contact us with store@sure-electronics.com for customization. Please note MOQ would be required.

Hi, Do you have an example of cascading of JAB5 as 8.0 and how to set this up in sigmastudio?

Hi.

You can take the JAB5 connection guide for reference.

You just need to set the switch on one JAB5 at M and other at S, then connect the I2S input and output port.

There is no need for any setup in SigmaStudio.

Hi. Thank you for the reply to my question about that how to use the external MCLK source on APM2. The answer is that the crystal oscillator needs to be torn down, using a disassembly tool. Do not have the schematic of APM2, so I wonder is the crystal oscillator (Y1) the only discrete component we need to take off?

Hi.

Yes. The crystal oscillator (Y1) is the only component you need to take off.

Hi there, I just received my APM2 modules with the ICP1/3 programmers. I tried to use APM2 as a i2s slave working with a i2s master which does USB-to-i2s bridging. In that case, the ADAU1701 MCLK source needs to come from i2s master instead of the onboard crystal oscillator (I believe its Y1 on APM2). Is there any way to make this happen like reworking APM2 board by taking Y1 off?

Hi.

Yes, the crystal oscillator needs to be tore down, using disassembly tool.

After that, your need to introduce a 12.288MHz clock signal from the I2S master device to ADAU1701 board.
