ART sla1 Manuale Utente

- 4 - 

 

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 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.
