A.C. Power Connection
It is important that the LS28SE be
connected via its supplied 15 amp
IEC 14-gauge power cord to a secure,
dedicated A.C. power receptacle.
Never connect to convenience power
receptacles on other equipment. Only
use the power switch on the front of
the LS28SE for On/Off control of the
preamplifier, or the IR input, RS232 or
remote control.
RS-232 Input
The RS-232 input allows connection of a
control or automation system.
IR Input
The IR input allows a remote IR sensor or
repeater system to be connected to the
LS28SE for control purposes, utilizing a
standard mono 1/8” connector.
12V Trigger Out
The +12V DC trigger out jack provides
the ability to remotely turn on and off the
preamplifier and other linked components
such as power amplifiers having similar
capabilities.
Important
Use the best available speaker wires
and interconnects. Audio Research
cannot emphasize this enough. As better
components and systems are developed,
it becomes increasingly important to
avoid the limitations of inferior system
interconnections.
It is important sonically that your entire
system be connected so that the audio
signal arriving at the speakers has correct,
or ‘absolute’ polarity (i.e., non-inverted).
