Page 3: Safety Precautions
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 or more Ohms. Using two speakers per channel, they must each be rated at 8 Ohms, or greater. -
Page 4: Introduction
INTRODUCTION Thank you for purchasing an ART SLA-2 Studio Linear Amplifier - and congratulations, you now own one of the most versatile amplifiers available. Offering a superb level of sound quality, the SLA-2’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 5: Installation
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. -
Page 6: Security Cover
This can be accomplished by using the Security Cover Plate which is included with the SLA-2. Simply set the channel attenuators to the desired gain settings, then press the knobs into the chassis until they lock in their recessed position. -
Page 7: Controls And Indicators
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. -
Page 8: Protect Led Indicator
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 condition at the speaker outputs (due to a severe load or short) the LED will light until the fault is removed. -
Page 9: Rear Panel Connections
REAR PANEL CONNECTIONS It is easy to interface the SLA-2 with a wide variety of equipment. All inputs and outputs are located on the rear panel. Standard EuroBlock, ¼” and XLR inputs and binding post outputs make patching simple. INPUTS The SLA-2 has three styles of input connections: EuroBlock, XLR and ¼”. -
Page 10: Xlr Input Jacks
AMP MODE SWITCH The SLA-2 Amp Mode Switch allows you to choose between Stereo Mode and Bridged Mono Mode. Make sure that power is off and that your speakers are wired appropriately when changing this mode. -
Page 11: Smartfan
Do not block the fan or constrict air circulation. Doing so may cause the amp to overheat and/or shutdown. FUSE The SLA-2 utilizes a (T10A 250v 20mm) 10 Amp fuse. Be sure to replace any blown fuses with a fuse of equal rating only. AC POWER INPUT The SLA-2 features an internal power supply. -
Page 12: Ground Lift Switch
OPERATION The main application of the SLA-2 is as a studio linear power amplifier for powering monitors. Connect 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). - Page 13 RF from the output and helps keep the amplifier stable with reactive loads. The SLA-2’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.
