Thank you for choosing this GE series graphic equaliser for your

application.  You have made an excellent choice.

The GE series are designed and built to be the most versatile

analog graphic processors available.

The combination of a full featured graphic equaliser with high

and low pass and shelving filters provides full control to even the

most exacting user.

The dynamics trim control and the 8 segment level/peak meter

provide headroom optimisation of the signal path.  This unique

feature makes it possible to reduce the noise floor of the unit by

as much as 12dB, making the equaliser virtually dissapear in

critical applications.

If a higher noise floor is acceptable, this control can create an

extra 12dB of headroom for the filter circuits, thereby minimising

distortion and clipping.

The autoranging power supply of the GE series guarantees trou-

ble free operation of these units all over the world, independent

on local mains conditions.

You probably want to start working with this new equipment right

away and not read all of the information inside this manual.

For those of you who are in a hurry, please read the safety in-

structions carefully.  Also the information about the DYN control,

a unique feature of these units, will be very enlighting.

Because  of  the  apparent  similarities  between  the  GE134  and

the GE234, both are covered together in this manual.
