bhi DSP

This product has been out for a little while, but I thought I would show it for those that are unfamiliar with bhi's DSP products. This is a DSP speaker unit:

 

 

The left side has a couple of buttons to toggle DSP filtering on and off, as well as set it to one of the five DSP filter levels. This is the same company that makes the DSP units for the GAP Hear-It speaker. In fact, they said that the GAP product is made by them, branded for GAP. I asked him how his products compared to the SGC speakers (since I have one). He showed me the audio graph of the SGC speaker, noting how it was very "rippled" I can attest to the fact that the SGC unit makes the audio sound warbled. A brief demonstration of this device showed that it's DSP is very effective at targeting just the audio portion without much distorion.

 

One design issue that I see with this unit is that it is difficult to use this in a mobile environment, where it is actually most desirable. The typcal mobile user that doesn't have a lot of dash/cab space for radio gadgets is going to want to install this under the seat or out of site. That means you're going to want to engage the DSP filter, set the desired filter level and then just forget about it, wanting it to turn on whenever you turn the vehicle on. Unfortunately, this device uses a little push button contact switch to set the level and engage/bypass the DSP, so you can't use it remotely. The rep said that the unit will remember the filter level, but not automatically engage the DSP filter after it loses power. I asked him if they could make a version that used an on/off toggle switch (or similar) to engage the DSP filter to solve this issue. He replied that I was the second person of the day that asked that question so he would talk to his engineer to see about designing something like that. If they come out with it, you heard it mentioned here first
