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 input, 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 easy plugs and even better value
Size: 6 pairs
Great plugs and amazing value for the money. Easy to use and tighten and the screw cover works wonderfully. Even comes with a couple extra screws in case you lose one. The sound is better than what I had and I used 14 gauge wire. Plugs were perfect, not too tight at all. I could see having to push for new posts but they are snug and didn't take too much force to put in. 10/10

Great looking and easy to install.
Size: 6 pairs
These 24K gold-plated banana adapter connectors have proven to be an excellent choice for my outdoor speakers, providing a clean and seamless installation. The quality of these banana plugs is outstanding. The 24K gold plating not only adds a touch of elegance but also ensures optimal conductivity and corrosion resistance. I appreciate the attention to detail in the design, which allows for a secure and reliable connection between the speaker wire and the speakers themselves. Installation was a breeze. The plugs fit snugly into the speaker wire, providing a secure connection that minimizes signal loss. The process was straightforward and hassle-free, allowing me to set up my outdoor speakers quickly and efficiently.

Very nice connection.
Size: 12 pairs
The banana connectors are great, I don’t know why I haven’t used them before. Very easy to install. I cut the wires and started fresh.

Great product but screws are annoying
Size: 6 pairs
These 24K gold-plated banana plugs are a solid choice if you’re looking for an easy and reliable way to connect your speaker wire. The connectors feel sturdy, and the gold plating gives them a clean, professional look while also helping prevent corrosion. Installation was straightforward — the wire slots fit snugly, and once tightened down, the connection feels secure. I used them for both my home theater and stereo setup, and the sound quality is clear with no noticeable interference or loss. The pack includes 6 pairs (12 plugs), which is plenty for most speaker setups, and they fit my receiver and speaker terminals perfectly. My only small complaint is that the screws could be a bit tighter or smoother when clamping the wire — you just need to make sure they’re seated properly to get the best hold. Still, once installed, they stay firmly in place.
