[. . . ] Here the 528E replaces their usual microphone preamp and either feeds their tape machine or workstation directly, in essence becoming a one-input, one-output console. Figure 7-2 illustrates the connections needed.

Using the 528E as a channel insert device 22 For best results, the 528E should replace the mic preamp in your console or recording chain. If you have to plug the 528E into a microphone input (-40 dBu nominal level), then you'll need to pad (attenuate) the output of the 528E down to microphone level. An internal jumper connection reduces the 528E's output to this level. Although a far preferable connection would be to bypass your console's mic preamp, this will work. When configured for mic-level output, the 528E's circuitry doesn't care if phantom powering is or isn't present at the console's mic input. Appendix A contains instructions for altering the output level of the 528E. Note: Padding (attenuating) the output of the 528E back to microphone level is a workable solution towards interfacing the 528E into a console or system having only microphone level inputs. However workable, the ultimate performance of the 528E will be limited by the performance of your system's existing microphone preamps. If you can find a way to bypass the existing microphone preamps in your system, do so. Using the 528E as a Channel Insert Device The 528E can also be used as a channel-insert device with your console. Use the 528E's line input and line output as shown in Figure 7-3. Using the 528E in an Effects Loop Signal processors used in a console's effects (send-receive) loop should not be insert or series1 processors. A series processor means that you have to break the signal path to insert the processor. Since using the effects loop does not break the signal path, we don't recommend that you connect the 528E here. Use the channel-insert jacks as described under the previous heading or insert the 528E between your console and your tape machine. Using the Patch Points Located on the rear panel are several TRS jacks. These jacks are the connections between the various processors that make up the 528E. The jacks are half-normalled, which means that without any plugs inserted, the signal flows through them via internal switching contacts. The term "half normal" means that only the input or return jack has switching contacts; inserting a plug into the output or send jack does not break the signal path. This allows you to access the signal at various points in the 528E's signal path for use with external processors.
