Architects’ and Engineers’ Specifications:

The device shall provide two balanced inputs which are selectable as line level or mic level with phantom power. The line inputs and output gains shall be controllable via software; the mic inputs shall be adjustable from the rear panel. Analog audio inputs and outputs shall be accessible via rear panel XLR and Euroblock connectors.

The signal processing Graphic User Interface (GUI) software shall be user programmable using Windows® 98, 2000, and XP operating systems. Software control shall be via RS-232 protocol and shall be located on both the front and rear panel. The GUI shall provide display, configuration and control of all signal processing functions including, but not limited to: • Input Gain and Mixing • Graphic or Parametric Equalization • Compression • Limiting • Gating • Automatic Gain Control • Ducking • De-Essing • Advanced Feedback Suppression (AFS™) • Notch Filters • Sub-Harmonic Synthesis • Matrix Mixing • Bandpass Filtering • Delay

Front panel controls shall include program selection and load buttons. Clearing feedback suppression filters shall also be provided for using the program up and pro- gram down buttons. A PC connection and Clip indicator shall be located on the front panel. The front panel shall also include input and output level meters with a 6- segment LED meter and output dynamics threshold LED.

External control shall include program selection, output level control and muting, and shall be via industry-standard CAT5 cable with RJ45 connectors. The device shall include 20 internal programs with up to 10 being user configurable. All program memory shall be non-volatile providing program security should power or computer fail.

Audio conversion shall be 24-bit 48 kHz. The dynamic range of the processor shall not be lower than 110 dB A-weighted.

The device shall have an IEC power socket. The unit shall meet UL/CSA and CE safety requirements. The unit shall be constructed of cold-rolled steel with a brushed and anodized aluminum front panel, and mount into a standard 19” 1U EIA rack. The device shall be a dbx DriveRack® 220i.
