INSTALLATION
The SLA-4 may be used in a wide variety of applications from project
or professional studio environments to commercial sound installations.
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-4 is no exception.
AC POWER HOOKUP
The SLA-4 has an internal power supply designed to operate at 120
VAC @ 50 to 60 Hz. Units manufactured for use outside of North
America have been modified to comply with the required electrical
specifications.
AUDIO INPUT CONNECTIONS
Audio connections to the SLA-4 are balanced or unbalanced ¼" [Tip =
Hot (+), Ring = Cold (-), Sleeve = (Ground)].
Euroblock connections: can be wired balance or unbalanced.

SPEAKER LOAD SAFETY 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 Ohms or greater.
When using two speakers per channel, in parallel, they must each be
rated at 8 Ohms, or greater.
When in bridge mode, the speaker load should be 8 Ohms, or greater.
