EBS Reidmar 502 D-Class 500 Watts Bass Amp Heead, 2 ohm Technology!

The EBS Reidmar 502. EBS Breaks New Ground With A Lightweight Bass Amp Featuring A New Class D Power Module Co-Developed By Ebs That Truly Handles A 2-Ohm Load.

Handles a 2-ohm load

The EBS Reidmar 502 handles a 2-ohm load so it can drive two 4-ohm cabinets simultaneously. To our knowledge, it is the first lightweight amp in the 500W-range that truly does that. And it does it with conviction too.

Efficient power handling

Due to EBS clever developed Soft-clip design, the Reidmar 502 makes efficient use of all the power at hand. That means more punch and a lot less compressed sound than with lightweight amplifiers using automatic limiters to prevent clipping. It keeps the bass tone from sounding muddy and preserves the lows solid on higher volumes.

Analog preamp

The preamp, featuring EBS renowned built-in compressor and a 4-band EQ-section, gives you full control. Use it to bring out anything from a warm nice low end, brilliant highs, and mids that cut through the mix when you need it.

Some other features include:

  • Onboard adjustable compressor.
  • Effects loop (send and return)
  • Balanced XLR-out for live and studio use (with pre/post EQ switch and Ground Lift)
  • Line out
  • Headphones output

Perfect Companions

If you prefer a compact rig, match the Reidmar 502 with a couple of EBS ClassicLine mini-size 112 cabinets, the new ClassicLine 210, or the NeoLine mini-size cabinets (for more clarity and punch).
For a more impressive look or when the gig calls for an even more powerful bass tone, you can use the Reidmar 502 with a couple of 4-ohm, 410 cabinets as well. A nice, well-balanced setup, that hits a sweet spot between power and portability is to use it with a NeoLine 210 and 212 cabinet together.
