IMPORTANT SAFETY INSTRUCTION – READ FIRST This symbol, whenever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure-voltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Read manual. Read instructions: Retain these safety and operating instructions for future reference. Heed all warnings printed here and on the equipment.

INTRODUCTION Thank you for purchasing an ART SLA-1 Studio Linear Amplifier - and congratulations: you now own one of the most versatile amplifiers available. Offering a superb level of sound quality, the SLA-1’s clean and powerful circuitry combined with a straightforward user interface quickly and easily delivers the power you need for professional and project studio monitoring.
PAGE 4
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.
PAGE 5
CONTROLS & INDICATORS – FRONT PANEL 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. CHANNEL ATTENUATORS The dials for channel one and channel two’s volume attenuators are located to the left and right of the Power Switch. When set to zero (fully clockwise), there is no attenuation of volume.
PAGE 6
REAR PANEL CONNECTIONS It is easy to interface the SLA-1 with a wide variety of equipment. All inputs and outputs are located on the rear panel. Standard ¼” and XLR inputs and binding post outputs make patching simple. INPUTS The SLA-1 has two styles of input connections: XLR and ¼”. Use these connections to connect the output signal from a mixer, preamplifier, crossover, or EQ to the amplifier. The balanced XLR connection is recommended for cable runs longer than 20 feet.
PAGE 7
AMP MODE SWITCH The SLA-1 Amp Mode Switch allows you to choose between Stereo Mode and Bridge Mono Mode. Make sure that power is off and that your speakers are wired appropriately when changing this mode. OUTPUT BINDING POST The SLA-1 Outputs for channels one and two are multi-connection jacks. You can use banana jacks, spade connectors or bare wire. Bare Wire Connections – unscrew the red and black caps on the binding posts (don’t completely remove).
PAGE 8
FUSE The SLA-1 utilizes a 7 Amp fuse. Be sure to replace any blown fuses with a fuse of equal rating only. AC POWER INPUT The SLA-1 features an internal power supply. Plug the detachable cable into a standard 110~120v wall outlet. Be sure that the supplied voltage matches that of the required voltage of your amplifier. Never plug the amp into an outlet that does not match the required voltage of your amplifier. Serious damage could result.
PAGE 9
OPERATION The main application of the SLA-1 is as a studio linear power amplifier for powering monitors. Plug source material directly into the inputs and set the output controls to provide an appropriate level into the next stage of your system (and an excellent choice for this are the ART SLM-1 Studio Linear Monitors). NORMAL OPERATION For a typical stereo setup, connect the source (mixer, eq, etc) outputs into channels one and two of the amplifier.
PAGE 10
PROTECTION The SLA-1’s output circuitry is fully protected from short circuits. An ultrasonic network decouples RF from the output and helps keep the amplifier stable with reactive loads. The SLA-1’s heatsinks do most of the work in getting heat away from the amplifier, in normal studio operation. A very quiet, rear mounted variable-speed fan provides extra cooling of the amplifiers internal circuitry as needed.

WARRANTY INFORMATION Limited Warranty Applied Research and Technology will provide warranty and service for this unit in accordance with the following warrants: Applied Research and Technology, (A R T) warrants to the original purchaser that this product and the components thereof will be free from defects in workmanship and materials for a period of three years from the date of purchase.
PAGE 12
SERVICE The following information is provided in the unlikely event that your unit requires service. 1) Be sure that the unit is the cause of the problem. Check to make sure the unit has the proper power supplied, all cables are connected correctly, and the cables themselves are in working condition. 2) If you find the unit to be at fault, write down a complete description of the problem, including how and when the problem occurs.
