Page 4: Introduction
Introduction Thank you for choosing the Quad EQ processor from Mackie. It is part of a family of digital outboard gear based on our TT24 digital mixer engineering develop- ments. We thought it would be good to share the love, not to mention the design and engineering expertise developed during the TT24 program.

Page 13: Filter Button
16. FILTER button This button provides you with access to the variable high-pass and low-pass filters of the current EQ chan- nel. Pressing the FILTER button engages and disengages these two pass filters at their currently edited settings. For the high-pass filter, the signal level of the fre- quency range below the filter frequency is attenuated by an amount determined by the high-pass filter slope.
Page 14: Rta Button
This can be useful for graphic EQs for monitor wedge mixes. A feedback frequency can be easily identified and cut using the Quad EQ in this way. EQD (EQ display) This option allows you to turn off the EQ filter set- ting display during RTA operation, so you can oper- ate the device purely as an RTA.

18. MIC button Pressing this button will engage the measurement mi- crophone input as the source for the analysis function, and it will light the button solid. The gain structure for this microphone input is set for the included measurement microphone, and 48 V phan- tom power is continuously applied to the input.
