I want to use two monitor speakers with or without subwoofer. Without sub, a Preset1 programmed in ACP Workbench shall direct the full frequency range to the monitor speakers. In case the subwoofer is connected I want to switch to a Preset2 that limits the monitor’s range to 80 Hz and directs the frequencies below to the subwoofer. How can I realize this in a way that the presets can be chosen from my app? Thank you for answering.
Sorry, I forgot to say that I intend to use the Up2Stream PlateAmp in the monitors and a wire connected Up2Stream Sub in the subwoofer. The crossover shall be programmed in the PlateAmp while the sub just reproduces what he receives via LFE from there.
Actually I haven’t build my speakers yet. I already purchased the Arylic boards but I’m still in the engineering phase. This means I don’t have any experience yet and need more detailed explanation.
I have already built such a setup with the plate amp. I combined Yamaha NX-E700 speakers with a Yamaha NS-SW050 Subwoofer and i still like this combination.
You can set up several parametric equalizers using the APCWorkbench software.
- left channel
- right channel
- subwoofer output
You can store presets on the global equalizer. This setting affects the left, right and sub. Your idea that the presets only affect a high pass filter on the left and right channel does not work.
Furthermore, it is not possible to change the presets via app, but there are 2 alternatives: Either via infrared remote control if you have ordered one or via the web interface.
The simplest solution will probably be to set the crossover frequency as low as possible, in my setup the speakers play down to 55 hz, below that the cut-off is very steep to protect the speakers and the amplifier. To be honest, i have to push it with more than 10db below 100 hz to play that low. For sure, this reduce the maximum volume, but i really don’t listen that loud.
The subwoofer then takes over from 35 to around 70hz, with a very flat low pass filter.
If I operate the speakers without the sub, I activate the Virtual Subwoofer function (D.Bass button) on the remote control. The function is also available in the web interface, but again not in the app. Set the frequency there so low that the speaker cannot play the frequency, in my example about 50 hz. This will give you the illusion of a deeper bass, as is the case with Bluetooth speakers, which produce incredibly fat bass for their size.
- The infrared extension does not fit to the plate amp by default, but i described it in this forum how to wire it
- The web interface may not work on your device, to fix it make a factory reset. I recommend you to do it before you do anything else
