INSTALLATION
The SLA-1 may be used in a wide variety of project and professional
studio environments. Self-contained in a steel and aluminum
enclosure, the unit is designed for many years of use. For greater
reliability, we recommend that you not place the unit directly under or
on top of other sources of heat. It is important that any rack-mountable
unit is properly ventilated, and the SLA-1 is no exception.
AC POWER HOOKUP
The SLA-1 has an internal power supply designed to operate at 115
VAC @ 50 to 60 Hz. Units manufactured for use outside the United
States of America have been modified to comply with the required
electrical specifications
AUDIO CONNECTIONS
Audio connections to and from the SLA-1 are balanced XLR [Pin 2 =
Hot (+), Pin 3 = Cold (-), Pin 1 = (Ground)] and balanced or
unbalanced ¼” [Tip = Hot (+), Ring = Cold (-), Sleeve = (Ground)].
OPERATION PRECAUTIONS
Warning: For optimum performance and reliability, do not operate the
amplifier with a speaker load of less than 4 ohms per channel, or any
combination of speakers that together are less than 4 ohms.
Using one speaker per channel, it must be rated at 4 or more ohms.
Using two speakers per channel, they must each be rated at 8 or more
ohms. When in Bridge Mode, the speaker should be rated at 8 or more
ohms.
