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

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.
