  • Great addition to a great DSP
Bought the date and DSP 408 to add to my system since it was at such a great price point for what you get. After using it with just the laptop connected to it for a while decided to pull the trigger on the Bluetooth module as well and couldn't be happier. Very easy to install and use and the app is a breeze and allows you to do changes on the fly instead of having the boot up the laptop connect it etc. Definitely would recommend 5 out of 5 stars. Using it in a car audio setup with stock head unit. 2008 Acura TL type S stock HU, Dayton DSP-408, Audio Apex CAB M-165 5CH AMP. ... show more

  • It works
I was a little worried about it coming loose since I have my DSP mounted on the side of my trunk close to 2 IDMax 12s in ported box but so far so good. I have the wired remote for on the fly subwoofer/volume/eq presets but it's nice to be able to go further into different options without having to bust out a laptop. ... show more

  • Will not work straight out of box...... see below. 5 stars, esp for individual speaker control
No sound? Seems DOA (Dead on Arrival)? Tech support said unit out of box will have no sound because all volumes are set to 0 initially. To change them I used the opt USB dongle https://www.amazon.com/gp/product/B07FNC6L34/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and Goodle Play Store app https://play.google.com/store/apps/details?id=leon.android.chs_ydw_dcs480_dsp_408) as I have android. I guess with windows, you don't need the bluetooth dongle for your phone if a direct wire is ok. Not sure about that though. App is not super intuitive, until you get used to how they think, so no discouragement just yet, ok! To get sound working, you have to increase several volumes via the app by finding the main volume control, then volume controls at each of the 8 channels one by one and at each of the 4 Input channels. Just kick any volume control up you find, we're just trying to get it working at this point, right? Initial setup to get sound working: 1) Download playstore App and plug in opt usb dongle (at least this is how I did it with android phone and bluetooth successfully paired to phone) 2) With app loaded in phone and USB dongle plug into unit for maybe 30 seconds, open the app. The phone should show a upload progress popup starting within a few seconds and a on screen power button symbol in upper right corner should go from red to green. Has to be green before continuing successfully. If all is good so far, the upload progress popup changes to a success popup after a few seconds. If not, make sure you're still paired to unit via phone's built in bluetooth app and if still no go, remember reboots are your friend. Reboot nit with USB dongle inserted and the with units small power led illuminated confirming phone is still paired. Processes are not super fast, so try to have a little patients. About 60 seconds worth of patience is plenty. 3) Phones app Initial screen should show main volume left/right slider. Slide it right to increase. 4) Scroll down to boxes 1 -> 8 (each representing a channel) and select one of the boxes and selecting each function box below that, increasing any volumes you find. Volume output should respond immediately if full audio is present, no audio..look for more volume controls. It's going to be a input volume, output volume or main volume or you don't have live audio in or the out is not connected. Can touch the RCA centers or click against each other to listen if amp is responding. 5) Continue volume search and increases for each channel individually (8 total) just to get some sound output 6) Voilà, sound through your amp and speaker.....right? 7) No?, darnit...well I tried. Call tech support on the condition they don't criticize my steps, I'm very sensitive you know. 1-800-338-0531 or email at tech@parts-express.com. Notes: -If you want to recall some favorite settings from the apps screen using clickable boxes (or by pressing the opt and cool looking wired volume control), then this function is it. This is why there is a Save button, click it then select either [Save] or [Recall]. -If you're hardwired, switch off (move left) the "steaming" slide switch (upper right corner) to prevent usb stream bypass of your wires. -To exit app, click the common looking circle power button icon little power circle icon changing it from green to red (upper right corner) to disconnect app from unit. Unit settings will not change because of the disconnect. If at any time the symbol is red, your not connected and screen changes will not be accurate or saved most likely. This can cause undo hair loss from pull hairs out of your head in frustration. -If background audio noise is heard during pause or quiet sections, consider using a set of Isolation Transformers inline @ at the RCA input Jacks. They are available in increments of 4 transformers good for 4 channels (need two for all 8 input channels) at JacobsParts (AP3054) https://www.amazon.com/gp/product/B00TEED91K/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1. You probably know, these can't solve all noise issues as noise can have different sources needing different kinds of filters. These are for grounding and dc noise. Noise that usually DOES NOT goes away when the low level RCA amp input is unplugged or noise that follows engine revs most likely need a different filter. Does not support speaker level amp inputs. Wish list- A spatializer/ambience/3D function selectable by channel. ... show more

  • Does what is supposed to do
Does what it's supposed to do. But definitely overpriced. If the convenience is worth the price is up to the buyer. Too bad it doesn't work with Android head units, but that's not the modules fault. 3 stars because it's simply overpriced.

  • Much too expensive, doesn't stay connected and doesn't play well with other Android apps
This BT adapter doesn't work very well if you are trying to use your phone to send audio (by any means) to a device other than the DSP. The usage case that needs this is to run the Android AudioTest app on the same phone that is running DSP control. The AudioTest app will send a tone sequence into the audio system (via headset jack to aux audio system input) and record the system response using a suitable mic (again via headset jack). The app will then show a table of data and plot of the response curve which is very useful for setting up the parametric EQ. Unfortunately: (1) the BT connection drops out frequently and (2) the DSP app will not control the DSP if the BT connection does not allow audio. I am using the DSP-408 for bass management only, not for full range signals so I have no use for the streaming mode and hence disabled streaming on the ap. I am able to get the DSP-408 BT device to pair and able to twiddle the DSP parameters but not reliably. The app does not control the DSP unless it has audio and in this case the AudioTest app sends audio to DSP which is not desired. Possible remedies are: (1)I use a PC USB connection to a PC to tweak EQ (I wanted to avoid this). (2) use two phones where one runs DSP-408 app and the other runs the AudioTest app (need two phones) (3). Possibly use "Separate app sound" mode under Android to direct the AudioTest app output to the headphone jack (so far no help DSP app still wants audio). I think the main problems are that the DSP-408 BT dongle should not require an audio connection to tweak the parameters and certainly should not drop the BT connection so frequently. Considering the inflexibility the DSP-408-BT dongle the price is way out of line. ... show more

  • Dongle is good- but look at other dsp's- this one is cheap but malfunctions
The bluetooth dongle is a must for the dayton dsp. I have to give the dongle 5 stars, but the dsp itself not so much. Malfunctioned in about 3-4 wks time. No help from mfr
