Operational Details
This section describes the details of operating the 528E. Usage information can be found later in
this chapter.
The 528E accepts monaural analog input signals at mic or line level, processes them, and delivers
them back to you as balanced line, unbalanced line or balanced mic level signals.
Stand-alone Operation
A vast majority of users use the 528E as a stand-alone device. Here the 528E replaces their usual
microphone preamp and either feeds their tape machine or workstation directly, in essence be-
com ing a one-input, one-output console. Figure 7-2 illustrates the connections needed.
