OSD Audio SMP500DSP Class D Subwoofer Amp is designed for use with higher wattage passive subwoofers such as in-wall subs that require external power. It is rack mountable and 1U chassis. This sturdy sub amplifier is not for the faint of heart. It serves up 1000 watts of power peak and 400W RMS @ 4 ohms, so to say that it is powerful is an understatement.
You'll experience deep, rich and crisp bass while watching your favorite movies, especially action and adventure flicks. A big bang for the buck, features include a front-mounted power meter, back panel adjustable gain and volume control limiter to protect the woofers as well as low-level and high-level pass-through input/outputs to cover newer and old school sound systems. Combining the best qualities of both class A and B amp technologies, distortion is low while efficiency is high, and the SMP500DSP Mono Amp also includes a variable high cut filter that routes higher frequencies to main speakers. This allows subs to concentrate on the low-frequency sound effects for which they are designed and keeps low bass away from your surround speakers for much cleaner highs and midrange.
This sub amp does more than just supply power. You'll notice an improvement in the overall sound quality of your entire home theater surround sound system.
I have a bose as5 sunning a pair of bose 151as speakers on my deck but feels like the set needs more bass. Wou!d your bass amp.be able to help of i also.get an outdoor sub? How would i.connect it as bose doesn't have a subwoofer output?
The SMP500 would be an excellent addition to your BOSE setup. We have a couple of choices for outdoor passive subs that would be a good match for your BOSE 151. Check out our FORZA 10 Passive 10" down-firing Deck/Patio Subwoofer (4 ohms). Or you can add one or two of our GLS8 8" in-ground subwoofer (8-ohm). The SMP500 will handle a 4-ohm load so one of the FORZA10 or one or two of the GLS8. The SMP500 features a Speaker (High) level input and Output so can be connected inline between the BOSE 5 and the Speaker 151. Or you can connect directly to Speaker B. And leave BOSE 151 connected directly to the Speaker A. I am pretty sure you could combine the SMP 500 in line with Speaker A and add a second pair of BOSE151 to Speaker B for even more coverage.
I need to know more about your application in order to answer your question better. What makes up the rest of your system? How many speakers will the subwoofer be working with (Brand and model numbers)? Do you have room for two Subs; the SMP500 will drive two of these subs. What other amplification are you using, what sources are you using? email@example.com
I would suggest connecting to Speaker B to the SMP500 while leaving your current setup with the Speaker B connecting to the Source A input of the Speaker Selector. The in-wall sub would wire directly to the speaker outputs of the SMP500 using 14 or even 12 gauge wire. You want to make sure the output is variable, so the master volume control from your AKAI affects both the high and low frequencies equally. Sometimes the Preamp level is fixed so you might need to adjust the volume from the SMP500. I would try it both ways.
Another thing to consider is are you using Impedance Matching Volume Controls for your protection (either the SSVC4 with internal IMVC or the DSM4/ISS4 with external IMVC). The AKAI should see an 8-ohn load on Speaker A from the Speaker Selector. The Impedance is not as much of a factor if you utilize the Preamp output from the AKAI to RCA signal level inputs. It would help to know more about your overall system. What Speaker Selector are you using, and what Brand and model number of the six speakers (3 pair) and In-Wall sub.
Thank you in advance; firstname.lastname@example.org
I have 4 outdoor Def Tech AW6500 speakers.
I am considering the following set up, please let me know if feasible:
Zone 2 line out from my Receiver to OSD SMP500 line in
I would like to connect two OSD GLS8 subs to the SMP500
How would I do this?
Would the SMP500 see a 4ohm load?
Next - line out from SMP500 to OSD XMP300 line in
How would I make this connection?
How would I connect the 4 Def Tech speakers to the XMP300?
Would the XMP300 see a 4ohm load?
Would the OSD AMP300 be better for this set up, or does the XMP300 work just fine?
What is the difference between these two amplifiers?
Which is better?
Great setup. The SMP500 would be ideal for driving the 2 GLS8 in-ground subwoofers. You have two choices for connecting the 2 GLS8's. I would recommend using our CL3 12/2 gauge speaker wire for the subs. You could run a single two-conductor to the first speaker and tie the inputs to a second two conductor pair to output to the second pair. The other choice would be to home run both wires from each GLS8 to the SMP500. In both cases, you have a parallel connection creating a 4-ohm load. Ideal for max power from the SMP500. Then you connect an RCA Stereo Cable from the signal level output to the Main RCA Inputs of the XMP300. Note: The XMP300 is a newer Digital design versus the Class AB AMP300. Typically the Class D Digital design features a 93% efficient Power Supply so no need for a heavy-duty power supply like the AMP300. You also have a higher power output from the XMP300 for a lower price as well. The XMP500 is also a Class D design with a similar physical size as the XMP300. You can not go wrong with either the AMP300 or XMP300.
You have made good choices, along with your Def Tech speakers.
According to our engineers, there is no factory reset; you would need to go through and make changes manually for each feature you might want to change.
