The M-1264's (M-1212E's) monaural inputs are electronically balanced.

They can be made transformer-balanced inputs using the optional input transformer LT-101 or LT-102.

How to mount the input transformer

Set the power switch to OFF and remove the power cord from a wall outlet.

Remove the unit's case by loosening six side panel screws (three each on both sides) and two rear panel screws.

Fix two sleeves to the bottom chassis using screws, then mount the transformer to the sleeves using other screws. (The sleeves and screws are supplied with the transformer.) When stacking two transformers due to the number or arrangement of channels, use the sleeves supplied with the M-1264 (M-1212E).

When changing the inputs 1, 3, 5, etc. located in the upper section, detach connector		from CN-104 connector,
connect the detached connector to the transformer connector	, and connect the transformer lead		to the
CN-104. When changing the inputs 2, 4, 6, etc. in the lower section, detach connector		from CN-105 connector,
connect the detached connector to the transformer connector	, and connect the transformer lead		to the
CN-105.
Replace the case.
