LS Output - LSA-4/2 card
The loudspeaker amplifier uses a bridged circuit producing high output power.
Therefore, neither output terminal may be connected to ground.
6.0 AMU Alignment Procedure
This procedure assumes that the user is familiar with precision audio equipment
alignment. All model variants are covered here so the user will understand the
function of the various controls.
It is recommended that an exchange card is obtained from TSL in the event of a fault.
Due to the complexity of these circuit cards TSL use a custom jig for accurate
alignment.
