THAT CONTAINED IN THE OPERATING INSTRUCTIONS UNLESS YOU ARE

QUALIFIED TO DO SO. REFER ALL SERVICING TO QUALIFIED SERVICE PERSONNEL.

The E-1231's input and output are electronically balanced. These can be converted to transformer balanced input and output using the optional matching transformer LT-101 (input) and LT-102 (output).

1.Set the power switch to OFF and unplug the AC cord form a wall outlet.

2.Remove the case by loosening six side panel screws (three each on each side) and two rear panel screws.

3.Install sleeves (supplied with the transformer) by tightening screws from the other side of a chassis, and mount the transformer to the sleeves using screws. See Fig. 1.The input transformer must be located on the left and the output transformer on the right.

4. When mounting the input transformer, detach

connector from CN-104, reconnect

the detached connector to connector at the transformer side, and then connect

connector from the transformer to CN104.
