Description

The S600X-W power amplifier board features two TPA3255 chips, delivering a maximum output power of 300W+300W+600W for powerful audio performance. It supports a wide input voltage range from 19V to 51V, making it suitable for various applications. In addition, the amplifier board comes with a DIY panel and AUX extension cable, eliminating the need to measure and drill holes when building Bluetooth speakers. With this panel, you can easily create your own Bluetooth speaker in just a few simple steps. The S600X-W power amplifier board supports multiple audio input methods, including Bluetooth, 3.5mm AUX, USB flash drive (FAT32 format, ≤32GB), and USB sound card input, making it compatible with the vast majority of devices. It offers a convenient user experience, and its diverse input options allow you to easily connect smartphones, computers, TVs, and other devices to enjoy high-quality audio output. To reduce noises and interference, you need to ground the amplifier board. Grounding effectively reduces electromagnetic interference and electrical noises generated during the operation of the amplifier board. It also minimizes hum caused by ground loops, providing clearer sound quality and more stable performance. The S600X-W power amplifier board is equipped with multiple built-in protection mechanisms, ensuring safe and reliable operation. It features overvoltage, undervoltage, clipping, short circuit, and overheating protections, preventing damage to the board and connected devices. NOTE: If the input voltage is 50V, the speaker impedance for the left and right channels must be greater than or equal to 4 ohms, and the subwoofer channel impedance must be greater than or equal to 2 ohms.

Power house of sound. I used mine for a mobile install on my e bike. Ran six Memphis audio speakers, 2 -6x9s,2-6.5 component set, and 2-5.25 ran in series with a impedance of just under 3. Oh and a skar evl 6.5 dual 4ohm sub. With the battery I used this thing makes people turn around from over 600 yards away, INSANE!!! ... show more

I built this speaker using this amp on 4x12v 10AH batteries in series for 48v. I blew the rotary dial I had on the horn. I also made the sub get warm durning my testing phase. The range is outstanding. Inside this box is betting like 40yrds on range as long as my phone has a straight view.

Model: S600X-W
This is a great little amp. No static on tuning knob. Plenty of power to drive my selected speakers (4 - 3in Magnadyne 50w speakers and a 5 CORE 12in 1200w subwoofer(WF12120)) in a custom enclosure using a 48v power supply.

    • Great product and customer service
Model: S600X-W
I damaged the lead to one of the potentiometers. I asked if they sold them separately. They don’t, but they shipped me a non functioning amp that I can use the potentiometer lead from. Great customer service and great product.

    • Great sounding board with a couple feature flaws. Customer support gets a solid A+, however!
Model: S600X-W
This amp is for my shed/shop/cave sound system. The idea was to mount it vertically to the back side (along with the power supply brick) of a piece of sanded 1/4" plywood in between the studs with the controls facing out near the wall mounted tablet for easy access. The amount of power (48V 10A brick) seems more than adequate for this setup as I'm not looking to annoy the neighborhood with an obscene amount of output. I just want a nicely dialed in system with a fairly flat frequency response that extends down to my subwoofer's tuning frequency, hence the decision to go 2.1 channel. The board seems well made (not sloppy and with decent capacitors). If you pay attention, you'll notice that a lot of these Class D board amps prioritize signal routing and packaging/board population over standardization of control layout. Maybe I'm picky, but for as long as I've been dealing with the world of audio, the frequency range (from spectrum analyzers to graphic equalizers) has always been represented with lows on the left, mids in the middle (if present), highs on the right. I appreciate the fact that this board has the tone controls properly positioned with bass to the left of the treble adjustment. I really like the front panel and how it's labeled, so swapping the surface mount treble/bass pots isn't really a solution unless one discards the nice front panel as well. Now on to why I deducted two stars (and unfortunately will be returning this board). The board has been on the test bench a few days now as I layout my wiring and sort out the speakers and enclosures, etc. It was only after I had both channels and the sub hooked up that I realized the main flaw of this unit. It lacks a master volume knob. The two sides of the amp are not at all integrated, and operate as completely separate amps. In other words, you can not simply blend in your sub to the main channels and then use the main volume knob as your system volume. I had everything dialed in for just a few moments of enjoyment and then my phone rang so I quickly turned the volume down to almost nothing and grabbed the call. To my dismay, I found the sub still going strong at its original level, which I had to turn down on its own. It turns out Dajunguo calls this lack of master volume "feature 1". Essentially, this means you upset the sub/mains blend every single time you adjust the volume for any reason. Upon realizing this, I reached out to the seller via chat to find out what my options are and after rejecting their suggestion to simply use the tablet volume upstream as the master volume since digital volume controls work by decreasing bit depth and thereby raising the noise floor to audible levels, I was pointed to the ZK-AS21P-W. It is supposed to be an equivalent board I should go for if I wish for the main volume to act as the master volume controlling the output of all three channels simultaneously. It's worth mentioning that only the "P" variant of the AS21 board is equivalent to the S600X and handles up to 50 volts. This morning, I walked into my shed to find the board in the off position (just as I left it last night) but having heated up to an extreme level where it was too hot to touch with bare hands! I hope one is not expected to unplug the brick every single time it isn't in use. The brick itself was not hot at all. The board turned on sending a loud thud through the sub followed by a loud crackle through the mains, then the fan kicked on and it cooled down to normal operating temperature within a few minutes. So, this knocks off yet another star. The only other annoying feature (which can be bypassed/tweaked and password protected with the Wuzhi App) is that despite the manual saying that bluetooth is bypassed when the 3.5mm aux cable is plugged in, the board still reverts away from the aux each time it is power cycled, requiring multiple presses of the main volume knob. I understand the other option is to unplug and plug the aux cable back in after power up for auto aux switch to occur. In other words when the manual says there is no way to shut off non password protected bluetooth other than plugging in the aux cable, they mean you have to power the board on and then plug in the aux cable to avoid the board grabbing your neighbor's bluetooth device as opposed to assuming that leaving the aux cable plugged in prevents the board from broadcasting that it's ready to hook up to any device with no authentication in its current range. All in all, these boards keep getting better and better with every iteration, so I'm hopeful that the next version will have at least some of the above mentioned bugs/annoyances worked out. UPDATE: I ended up realizing I was actually missing some items from the package the day after I had posted this review. So, just coming back here to say that customer support has been nothing but top notch! Yes, this means two stars deducted due to features of the amp but a bonus one added for customer service! :) ... show more

Combined with an 2ah M18 battery it provides 5 hours with 4 6.5 speakers at very high volume and clean sound.
