Hz The GQ 7 offers five processing modes Stereo Mid Side Mid Solo and Side Solo The default mode is Stereo which equalizes one or two channels of audio according to the current parameter settings Choosing Mid processes just the center signal leaving the difference between the left and right channels untouched Choosing Side processes only the difference between both channels but not the center Using Mid Solo and Side Solo you can solo either the Mid or Side channel This way the unprocessed channel is no longer audible To equalize the Mid and Side channels with separate EQ settings simply put two GQ 7 instances in series then set them to Mid and Side modes respectively 3 6 Spectral analysis By default the GQ 7 performs a spectral analysis of the incoming signal in real time Note that while the horizontal axis showing the frequencies from 25 Hz to 25 kHz is identical for both the EQ curve and the spectral image the vertical range is different The spectral analysis always uses a range between 0 dB and 90 dB regardless of the current zoom setting This is necessary to be able to see enough of the signal spectrum If desired Spectral Analysis can be turned off on the back panel This can be useful to save some processor time when using many instances of the GQ 7 simultaneously GQ 7 User s Manual 8 3 7 Volume Knob SYNAPSE GQ 7 GRAPHIC EQUALIZER All In 2 E als 15 VOLUME The volume
