Introduction

The EQ573 is based on the famous design of the classic 1073 and 1084.
It can be used as a stand alone unit through the lunchbox XLR's or in tandem with the MP573
mic pre, as an insert between the input and output stages, recreating the full architecture of
the 1073. The switching between the two modes is done on the front panel, allowing the use
of both modes.
The EQ573 is a three bands parametric EQ (High shelf, Mid, Low shelf) and a variable High pass
filter.
The EQ573 enhances the possibilities of the 1073/1084 by adding several frequencies and
Q's:
Stand alone installation
Insert the EQ573 into a free slot in the lunchbox (or rack). Do not omit the 2 fixing screws on
the module front plate before moving. It is pretty heavy and the weight would put too much
pressure on the back connector.
Installation with a MP573
You need a free slot, next to the MP573.
Remove the jumper from the CN1 connector on the MP573 and plug one end of the link cable
into it.
Connect the other end of the link cable to connector CN2 on the potentiometer PCB of EQ573
then insert the EQ573 into the lunchbox, making sure the link cable passes above the EQ module.

XLR Connections

In the XLR mode, the EQ connects to the rear female XLR for input and to the rear male XLR for output.
In the Pre mode, the rear XLR's are simply connected as a pass-through.
The XLR pinout is as follows :
Pin 1 : Ground
Pin 2 : + Signal
Pin 3 : - Signal
