274 Quad Expander/Gate
DBX - 274 Quad Expander/Gate

The DBX 274 has four independent channels of user selectable gating. Each channel of the 274 has an assignable input filter that can be used to make the gate more responsive to certain frequencies. The noise gate features threshold and hold control that allows the user to set the level at which the gate starts affecting the gain. Additionally, the gate employs controls for depth and release, switched radio control, input and a stereo slave switch. The level of user control combined with the clear and intuitive layout for rapid setup makes it a great addition to any project studio.

The Quad Gate is a part of the new dbx Project 1 series that take advantage of the latest technology to provide high quality at an affordable price

Rolls - DB225 Direct Box
Rolls - DB225 Direct Box

The DB225 is a transformer balanced, passive professional direct box. It features a Ground Lift switch for hum elimination, and an Attenuator switch for padding the input signal from -20 or -40dB. Padding the input signal provides a way to connect the DB225 to a line level signal, even a speaker level signal and connecting it to a balanced line or Mic input on a mixer. The two 1/4 inch; inputs are paralleled pass-through to also send the input signal to a tuner, pre amp, etc..

  • Attenuator switch to select the exact level you want
  • Ground lift switch to help eliminate ground loops
  • Frequency response 20 - 20K Hz + - 1dB
  • Output imp. 600 ohms
  • Input Impedance 50K ohms
  • Max output level +4 dBm
  • Weight 1 lb, 0.45kg
