4 INTRODUCTION Thank you for purchasing an ART SLA- 2 Studio Linear Amplifier - and congratulations, you now own one of the most versatile amplifiers available.
5 INSTALLATION The SLA-2 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.
6 SECURITY COVER For commercial installations it may be desirabl e to set the gain controls on the power amp, and then make them in accessible t o non-qualified operators. This can be acco mplished by using the Security Co ver Plate which is included with the SLA-2.
7 CONTROLS & INDICATORS – FRONT PANEL FRONT PANEL DIAGRAM POWER SWITCH The Power Switch is located on the front of the unit, directly in the center. During initial installation, make sure the attenuators for channels one and two are set to a low volume level before applying power.
8 PROTECT INDICATOR LED The LED will glow when the channel goes into protect mode. In protect mode, the output signal to the speakers will be muted (channel specific). If there is a fault condit ion at the speaker outputs (due to a severe load or short) the LED will light until the fault is removed.
9 REAR PANEL CONNECTIONS REAR PANEL DIAGRAM It is easy to interface the SLA-2 with a wide variety of equipment. All inputs and outputs are loca ted on the rear panel. Standard EuroBlock, ¼” and XLR inputs and bind ing post outputs make patching simple.
10 XLR INPUT JACKS The XLR Input jacks are Pin Two posit ive, Pin Three negative, and Pin One is ground. This connection is for balanced connections. EUROBLOCK BARRIER STRIP Insert the wires, then snug down with the set screw. The entire barrier strip can be removed fo r quick service without disconnecting the individual wires.
11 Spade Connector – Loosen the red and black caps on the binding posts (don’t completely remove). Insert the spade connector into the binding post and tighten the caps down on the spade connector. Be sure that the wire c onnected to one post does NOT come in contact with that of another post.
