The Orban 764A Programmable Parametric Equalizer provides superior equalization in a fully-programmable package. Its flexibility and efficiency provide all the equalization you need to precisely define the sound of all audio tracks and instruments — and, when you’ve got the equalization you want, the Programmable Parametric Equalizer remembers the control settings so you can produce the same sound later, with the push of a button. Optional 764A/SL Slave units provide additional programmable parametric equalization. 764A Programmable Parametric Equalizer features include: • Four-band parametric EQ with variable frequency, bandwidth, and boost/cut for precision control. • Continuously tunable 18dB/octave high-pass filters and 12dB/octave proprietary Automatic Sliding Besselworth™ low-pass filters that provide full flexibility while retaining maximum musicality. • Instantaneous access to 99 user-programmed control setups. • Input attenuator which can be used as an automated fader or mute. • Parameters adjusted with rotary encoders for analog style operation. • Digital display of current control settings. • Noise and distortion specs significantly better than 16-bit digital. • Up to 99 channels of equalization which can be controlled from one master unit. • Memory protected by internal back-up battery. • Security code to lock programming controls and prevent tampering. • Optional MIDI, RS-232, or RS-422 interface.
