Up2Stream Plate Amp 2.1 portable sound system with Dayton Audio Epique subwoofer and passive radiators


My first project using the great plate amp

Love the plate amp - makes it easy to get a clean and professional setup.
My first project sounds great, but the passive radiators I used hev problem to handle high volume.

Decided to start a new build (v2) where I replace the subfoofer and radiators with the 7" Dayton Audio Epique + 2 x Epique passive radiators (hope this is a ok combination)

I`ll keep the DD audio 5.25" speakers to handle mid/high frequencies.

And the great plate amp…

Have started working on the updated design - I`ll share images later

Playing with the v2 design (only one speaker at the moment)
I`m going to use the same speaker positions as in V1

The idea is something like walnut on top/bottom and balck leather on the front/sides…

Something like this (not the correct speaker elements in the 3D model)

The led ring is a combined push button/RGB LED used for mode selection (Bluetooth, WiFi…) each mode have a different color (I`ll share more information about it later)

The Up2Stream Plate Amp 2.1 at the rear.

This amp is perfect for projects like this - a lot cleaner/more professional setup compared to my first build where I used the standard 2.1 module.

The old passive radiator used in v1 vs the new one for v2

Exiting

First test installed in V1 (not tuned…)

Have to find some better test music

Hope your neighbors enjoy :sunglasses:. Don’t forget to provide some details on the LED ring you mentioned.

In my V1 project I used a RGB led ring push button - different colors = different modes (bluetooth, usb…)

But in V2 I plan to use a NeoPixel led ring push button in combination with a arduino to get more colors/more options… (winter project)

I promised to share how I connected the RGB mode select push button in V1


Made a simple wireing diagram

Made a short demo video

Solid Green = WiFi connected
Blinking BLUE = Bluetooth not connected
If I connect using USB, I get solid Red

Used the connector at the mid top (same as on the standard Amp 2.1

You can add other buttons for Vol +/- … by including more push button/resistor combinations.

For V2 I plan to test a setup where I use a neopixel based bush button in combination wit an Arduino to cover all modes…
It is also possible to include a small OLED display that can display the mode using text

In V2 I`ll include control buttons (previous, next, pause/play and vol up/down)

I`m going to use an PS-BC12113 BCPB4 Battery Manager Module 5x26650 for my V2 build

Some parts for my new neopixel led ring button for mode select/status arrived today - soon I’ll have all the parts I need to test my idea :blush:

I`m going to order some walnut wood for my V2 build
Love the look

First test - Neopixel led ring mode select button

In this test I use 4 buttons to simulate 4 modes (bluetooth, Wi-Fi …)

The colors are only for test - I can use other colors)

Some design updates - while waiting for the Walnut wood…

Plan to install braces like this

Not decided if I should make a dedicated chamber for the Arylic Plate Amp + battery module
