July 25, 2001PreSonus unveils the DEQ624 Stereo Graphic Equalizer. The DEQ624 utilizes 24-Bit Digital Signal Processing yet gives the user a familiar analog interface. The two 31 Band Equalizers offer three switchable ranges of operation: +/-6dB, +/-12dB or +12/-24dB.
A Security feature on the DEQ624 locks out all of the front faceplate controls using a programmable password-style of access. Once engaged, the DEQ624 will retain all of the settings programmed by the installer, regardless of power shutdown. The user has the ability to recall up to four presets on the DEQ624.
In addition, the DEQ624 features a brick wall limiter with variable threshold as well as a downward expander featuring variable ratio and threshold.
A unique feature on the DEQ624 is AHC (Adaptive Hum Cancellation). When engaged, this algorithm identifies 60 Cycle Hum caused by ground loops and dimmers and uses phase cancellation to eliminate the problem without causing any alteration to the audio.
The DEQ624 also features High and Lo Pass Filters (20Hz-20kHz) as well as Hi Q for selected frequencies. When the Hi Q button is engaged, it changes the standard 1/3rd Octave Q (4.75) to a tighter 1/8th octave notch (8.0).
Lastly, the DEQ624 features a ‘Channel A Master Mode’ which when engaged allows a mirror image of Channel A’s controls to be duplicated on Channel B, while keeping the audio paths independent.
The inputs and outputs of the DEQ624 include XLR Balanced, 1/4" TRS Servo Balanced and Barrier Strips for permanent installation.
