A surprisingly compact 12-channel amplifier with a new generation 12-channel DSP. 6 channels of RCA inputs, 12 high-level inputs, coax SPDIF input, optical TOSLINK input, Bluetooth AptX HD optional input, optional digital remote control for volume, sub level, preset selection, input selection, mute trigger. 12x50W RMS @ 4 Ohm output channels (at <1% THD+N), 12-channel RCA output, this DSP amp has it all. Perfect for 3-way active front + active rear amplification with an external subwoofer amplifier or 4 Ohm subwoofer on bridged channels 11 and 12 (yes, these are bridgeable even if undocumented). The powerful multichannel input EQ, time alignment and allpass filtering allows for proper OEM integration. A compact, dense multichannel DSP amplifier with very powerful DSP functionality for full integration in the modern multichannel active systems. Infinitely expandable to use high-end external amps via its 8V RCA outs on every channel - you can also use this DSP amp as a standalone DSP if need be. It's truly an universal all-in-one unit!

The DSP supports the following on every output channel:

  • High pass, low pass and band pass crossovers (Linkwitz Riley, Bessel and Butterworth) up to 48 dB/oct
  • 31 band fully parametric EQ with +/-15 dB correction, Q-value 0.3 to 15
  • 1st and 2nd order Allpass filters with Q control and inversion (each of the 31 EQ bands can be switched to Allpass)
  • Time delay up to 15 ms for time alignment, selectable in ms, cm or inches, optional linking of channel pairs
  • Phase phase switching between 0 and 180 degrees
  • Level correction from 0 to -40 dB, optional linking of channel pairs
  • Fully functional input mixer, live mixing of inputs (2 inputs active in parallel), allows the set up of a differential rear fill
  • Internal pink noise generator to test each individual output channel

The input of the DSP supports the following corrections on every input channel, including the COAX, TOSLINK and Bluetooth, separately:

  • High pass, low pass and band pass crossovers (Linkwitz Riley, Bessel and Butterworth) up to 48 dB/oct
  • 10 band fully parametric EQ with +/-15 dB correction, Q-value 0.3 to 15
  • 1st and 2nd order Allpass filters with Q control and inversion (each of the 10 EQ bands can be switched to Allpass)
  • Time delay up to 15 ms for time alignment, selectable in ms, cm or inches
  • Phase phase switching between 0 and 180 degrees
  • Level correction from 0 to -40 dB

Great shelves!
Size: 24x5.8, Color: Black, Size: 24x5.8, Color: Black
I love these shelves (I purchased 6 shelves total). The size I got was perfect, looks phenomenal, & quality is great too! Only negative thing I’d say is that it could be difficult for some people to set up as it needs to be leveled, & can be hard to align with other things since the part that attaches to the wall is separate from the shelf (due to its floating design) but once it’s up, it looks great. Definitely good value for money with its quality. I have them to hold up decorations/toys, & you think some of my shelves have about 5lbs of stuff on it & I’ve had no issues, so functionality is good.

Extremely satisfied

Very nice. I am extremely happy with them. I used painters tape to hold the bracket in place while I screwed it in, worked like a charm 😁 holds a lot of items

Good enough
Size: 15x6.8, Color: Black
As cheap as the day is long but functional. These are basically made out of highly compressed paper and finished to feel like wood. The first one I put up was good with a little tilt to the back which is fine. The second one has a more severe tilt and I had to bend the bracket down to decently level it out. They are sturdy enough to hold quite a bit of weight and look good for what they are. I'm not impressed but I'm also not disappointed, the price is a bit steep for what they are but they serve their purpose.
