400W of pure bass power deliver an enormous, fat, warm sound!

8 - 6550 vacuum tubes are at the heart of this amp. Ultrawide frequency response is accomplished through the use of a specially designed toroidal output transformer. It's built for the road and has a reputation for extreme reliability. Features include 2 sets of speaker outputs in both banana plug and 1/4" configurations and a preamp thru for hooking up multiple power amps. The DB 728 has a "soft start" for the regulated screen voltage, a feature found only on the best audiophile amps. 2 large whisper-quiet fans keep the amp cool and have high and low speeds for nearly silent operation.

  • Power output: 400W RMS. Into 2, 4, or 8 ohms
  • Transformers: Custom-designed toroidal output transformer for ultrawide bandwidth Power transformer is also toroidal
  • Outputs: Speakon connectors and 2 - 1/4" outputs
  • Inputs: One 1/4" unbalanced input and one input thru for patching a preamp signal thru to an additional power amp
  • Output Impedance Selector: A 3-position switch provides switching for 2, 4, and 8 ohms
  • Calibration: 2 bias trim pots, plus a driver balance trim pot, provide for perfect calibration of the unit
  • Cooling: 2 whisper-quiet fans regulate the operating temperature of the amp
  • Weight: 57 lbs.
  • Chassis: High-quality aluminum construction provides sturdiness without excessive weight

Raw Power

By Topher The Thumb

from Manteca, CA

I've been playing through the Aguilar DB 728 for about a year now and have never been happier with my sound. I've tried many power amps from SWR, Eden, Ampeg, Crown, and self constructed, and none of them have lived up to the warm ridiculous punch of the Aguilar. I recommend it to every bass player I meet and always get asked what I'm playing through at shows.
