1. DUMP PRESET SENT When performing a system exclusive dump from the CEQ 28R its MIDI output need not be connected to the CEQ 28 MIDI input 6 CEQ 28R MIDI COMMAND SUMMARY The CEQ 28R responds to MIDI program change com mands by recalling the Preset EQ curve requested The CEQ 28R must be listening on the correct MIDI channel or be in OMNI mode When the CEQ 28R receives a valid program change command it will display 3 bars in its front panel display The CEQ 28R will receive MIDI controller commands that are on the correct MIDI channel and for controller numbers assigned to EQ sliders or switches The CEQ 28R responds by displaying the 3 bar MIDI activity indicator and by changing the appropriate EQ slider or switch When in OMNI mode the CEQ 28R will receive MIDI controller changes messages sent on any channel The system exclusive messages that the CEQ 28R sends and receives are outlined in the MIDI implementation anntinn 7 FACTORY RESET OF MEMORY If you have changed many of the MIDI communication parameters or if you wish to erase all of the EQ curve stored in memory you can reset the CEQ 28 s memory to the factory settings CAUTION When the following action is performed all of the stored curves EQ settings and other setup changes are returned to the factory settings ALL STORED CURVES ARE LOST If you wish to save any of the stored curves use a MIDI System Exclusive dump to the CEQ 28 Connect the CEQ 28R and CEQ2. OPERATING INSTRUCTIONS CEQ 28R INTRODUCTION 1 DESCRIPTION Thank you for purchasing the Peavey Architectural Acoustics CEQ 28R If you are not yet familiar with the operation of the Peavey Architectural Acoustics CEQ 28 we recommend that you take a few minutes to read the CEQ 28 manual and familiarize yourself with its operation before proceeding with this manual The CEQ 2BR is a 28 band 1 3 octave graphic equalizer that isa companion to the CEQ 28 It can be used asa slave equalizer that tracks EQ changes made on the CEQ 28 or as an independent equalizer that is remotely controlled from the CEQ 28 When the CEQ 28R is used as a remote expander the CEQ 28 front panel controls and display are used to control the CEQ 28R so that it operates just like the CEQ 28 By adding CEQ 28Rs up to 16 channels of audio can be individually equalized from one CEQ 28 Once curves are loaded or created in the CEQ 28R the CEQ 28 can be removed so that the EQ curve you have carefully created cannot be altered However any of the 128 stored curves can be recalled via MIDI program change commands if enabled or the CEQ 28R can be set to a mode that allows one of 2 4 or8 presets to be recalled from the front panei 2 FEATURES e 28 Band graphic equalizer on 1 3 octave centers e 26 Band constant Q filters e Top and bottom bands 32 Hz and 16 kHz are shelving filters e MIDI controllable sliders 12 dB in 1 dB steps or 6

4. as you manually adjust an EQ slider on the CEQ 28 the same change is being made on the CEQ 28R You can confirm that the CEQ 28R is getting the messages if the CEQ 28R display changes to 3 bars when an EQ change is made What we have not yet considered is that the two equalizers may contain different EQ curves when we start Each time an EQ band is adjusted on the CEQ 28 the corresponding band on the CEQ 28R will be set the same However if you don t adjust all bands of the equalizer then the unadjusted bands may be set differently Itis best to either set both equalizers flat or recall identical curves before starting manual adjustment We also must consider what happens when a curve is recalled on the CEQ 28 Performing a recall on the CEQ 28 causes the corresponding preset on the CEQ 28R to be recalled But if the CEQ 28 and CEQ 28R have different curves stored in their preset memories the two EQ curves will be different The best way to solve these problems is to dump the desired preset curves or ALL presets via a system exclusive dump from the CEQ 28 to the CEQ 28R Then recall one of those curves to assure that both units have the same EQ settings If you create a new curve and store it in the CEQ 28 be sure to remember to also dump the preset containing the new curve to the CEQ 28R If you want additional CEQ 28Rs to track the master CEQ 28 connect each in turn to the MIDI output of the previous CEQ 28R Taking the signal fr
