The DSP has three pre-programmed EQ settings (REF, EQ1, EQ2). On the 4 mm thick aluminum plate the SA-1 has several means to adjust the sound. We recommend trying to even out peaks instead of trying to fill in dips, as a dip most likely occurs due to a wave cancellation and adding more power to the affected frequency will only increase the cancellation. ![]() Trim the PEQ frequency knob to the correct spot and adjust the PEQ gain to balance out the dip or peak. Then on the SA-1 amp set the PEQ mode to On and set the PEQ gain knob to either +9 dB or -9 dB to see which frequency is targeted. Start by using Real Time Analysis (RTA) measuring at ear-height at a couple of different locations in your listening area to see if a certain frequency range has a repeating pattern, for example a dip or a peak. ![]() To use this feature in the best way we recommend using measuring eqiupment like the XTZ Room Anayler II Pro to get a sense of how the system is performing within the listening area. The PEQ can target frequencies between 30 Hz and 120 Hz, +/- 9 dB. The EDGE SA-1 sub amp has a built-in parametric EQ (PEQ) where you can target and compensate for issues with room modes and nodes that are unique for every listening area. Pre amp stage developed by XTZ and ICEpower.In that case it will be programmed with a firmware where all DSP settings are neutral and not optimized for a particular XTZ subwoofer. XTZ CINEMA SUB 1X12 (including conversion plate)Ĭhoose the desired firmware version for the XTZ subwoofer you want to use the amplifier with, or choose "Neutral DSP" if you want to use the amplifier with your own build. The EDGE SA-1 sub amp is equipped with an advanced digital signal processor (DSP) which gives the amplifier extreme control over the driver, and has extensive adjustments available via two EQ tools: pre-programmed EQ settings REF, EQ1 and EQ2 plus the built-in parametric EQ (PEQ). ICEpower modules is used in many very costly high-end designs thanks to its extreme performance (S/N ratio of 117 dB) and huge power vs. SA-1 is a mer advanced amplifier than previous subwoofer amplifiers, has more power and improved impulse response. Opinions? If I should replace it, what $200 or less sub would be on par with the Velodyne.The new subwoofer amplifier EDGE SA-1 is built with the best class D technology from ICEpower® capable of 700 Watts RMS and is a part of the SUB 10.17 Edge, SUB 12.17 EDGE and CINEMA SUB 1X12 EDGE among other models. I've been blowing cash like crazy on this basement (plus other stuff), so spending $600+ on a sub is not in the cards right now. The sub and enclosure are in perfect shape.but is it worth dumping $156 to make it work again vs buying a $200 or less new sub (or used if I find someone local selling something decent)? I am too project heavy to think about component testing/repair on the Velodyne's amp if it can even be salvaged. Looking online, the only amp that I found that seems to fit the opening on my Velodyne is this: Well, I'm finishing my basement, doing in-wall speakers and another small home theater.so I need a sub. State Farm was good to me and I did some upgrading, replacing it with a Rythmik 12" ported sub and stored the Velodyne away for a rainy day. Yes, I have since upgraded surge protectors and installed a whole home surge protector. About 7 years ago, we had a lightning ground strike that fried a number of things in our home, including the amp on the sub. ![]() Was my main sub for years and performed well for what it is (10" ported sub, 250watts RMS). I have a Velodyn CT-100 I bought 20 years ago (yes, in 1999 - hard to imagine it was that long ago).
