INSTALLATION
The ART SCL2™ may be used in a wide variety of applications and environments. Housed in a rack-
mountable, all-steel enclosure, the unit is designed for continuous professional use. Mounting location is not
critical. However for greater performance and reliability, we recommend that users not place the unit on top of
power amps, or other sources of heat and/or strong magnetic fields.
Unpacking
The SCL2™ was packed with care at the factory. The shipping carton was designed to protect it during initial
shipment. Please retain this carton for use in transporting SCL2™ when it is not installed in a rack, or in the
unlikely event that the SCL2™ requires servicing. The shipping carton should contain:
- SCL2™
- The user's guide
- Power cord
AC Power Hookup
SCL2™ has an internal power supply designed to operate at 105 to 125VAC, 50 to 60Hz. Units
manufactured for use outside of the United States have been modified to comply with the required electrical
specifications for the country of use. Under no circumstances should the power cable be altered. If the cable
becomes cut or damaged, discontinue its use and have it replaced before operating
SCL2™.
The power source must provide a good ground connection, and the ground pin on the mains plug should
never be defeated.
Analog Audio Connections
Audio connections to and from SCL2™ are:
Balanced input: [XLR] Pin 2 = Hot (+), Pin 3 = Cold (-), Pin 1 = Ground
[1/4”] Tip = Hot (+), Ring = Cold (-), Sleeve = Ground
Balanced output: [XLR] Pin 2 = Hot (+), Pin 3 = Cold (-), Pin 1 = Ground
[1/4”] Tip = Hot (+), Ring = Cold (-), Sleeve = Ground
Unbalanced 1/4” cables may be used with no damage to SCL2™, however, we strongly recommend users
use a balanced connection whenever possible to reduce noise. We recommend using only high-quality cables
equipped with the appropriate connectors.
