The Whirlwind Director Single Channel Direct Box is everything you need for going direct in one simple box.
This passive Whirlwind Director Deluxe Direct Box converts line, instrument, or speaker level signals into a low impedance mic level. The Director's input is Hi-Z bridging. The DI box includes a 30dB pad switch for selecting level, a switchable low pass roll-off filter to eliminate amp noise, and a ground lift switch on the Lo-Z output.
