ST260’s internal bus structure
In order to gain access to the internal bus structure, you must first remove the top cover.
Turn the amplifier so the rear panel is facing your. The jumper modules may be seen
on the circuit board just behind the level controls.
Below is the default setup for the ST260 amplifier. By arranging the jumpers allows you
to configure the amplifier for different applications. If you wish to use the amplifier as a
stereo (two channel) amplifier, you need not change any of the settings.
In order to reconfigure the ST260’s channels, remove the source control group jumper
from its present position (if necessary) and install it on the terminal you wish to select as
the source for that channel. Make sure it has been inserted on both terminal pins of the
jumper modules.
To complete the configuration, the volume group jumper should be placed at either the
‘USE VOL’ or ‘NO VOL’ terminal depending on you configuration.
Note: A channel that is not being used in your configuration should have its jumper plugs
installed at the default position as shown in Figure F.
Jumper description
Figure G illustrates the jumper modules used in
configuring each channel. Each jumper terminal
location is conveniently labeled as to the source it
can be configured to provide. Explained further on
the following page.
