Page 6: Installation
INSTALLATION The SLA-4 may be used in a wide variety of applications from project or professional studio environments to commercial sound installations. 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 7: Security Cover
This can be accomplished by using the Security Cover Plate that is included with the SLA-4. Simply set the channel level controls to the desired gain settings and press the knobs into the chassis until they lock into their recessed position. -
Page 8: Controls And Indicators - Front Panel
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 level controls for each channel are set to a low volume level before applying power. CHANNEL LEVEL CONTROLS The dials for the four channel level controls are located to the left and right of the Power Switch. -
Page 9: Protect Indicator Led
(due to a severe load or short) the LED will light until the fault is removed. Channels One and Two share a Protect LED, as do channels Three and Four on the SLA-4. The protect lights will also light during power up and down, to indicate that the signal is muted. -
Page 10: Rear Panel Connections
REAR PANEL CONNECTIONS It is easy to interface the SLA-4 with a wide variety of equipment. All inputs and outputs are located on the rear panel. Standard ¼” and Euroblock inputs and binding post outputs make patching simple. INPUTS The SLA-4 has two styles of input connections: ¼” TRS and Euroblock. -
Page 11: Stereo / Bridge Amp Mode Switches
STEREO / BRIDGE AMP MODE SWITCHES The SLA-4 Amp Mode Switches allow you to choose between Stereo and Bridged Mono Modes. Two separate switches allow you to bridge channels 1 and 2, or channels 3 and 4, or both channel pairs. This maximizes flexibility by allowing the amp to be configured for best utilization in 2, 3, or 4 channel applications. -
Page 12: Smartfan
SMARTFAN™ The SLA-4 features SmartFan™, an advanced, thermal dependent fan assisted convection cooled system. The SmartFan™ system is dependent upon the internal ambient temperature of the unit, and runs at two different levels. -
Page 13: Fuse
FUSE The SLA-4 utilizes a (T10A 250v 20mm) 10 Amp fuse. Be sure to replace blown fuses with a fuse of equal rating only. AC POWER INPUT The SLA-4 features an internal power supply. Plug the detachable cable into a standard wall outlet. Be sure that the supplied voltage matches that of the required voltage labeled on your amplifier. -
Page 14: Operation
OPERATION Connect source audio material directly into each input channel and set the channel level controls to provide an appropriate level into each channels speakers. NORMAL OPERATION For a typical four-channel setup, connect the source (mixer, eq, etc.) outputs into channels one thru four of the amplifier. Connect your speakers to the outputs on the rear of the amplifier. - Page 15 RF from the output and helps keep the amplifier stable with reactive loads. The SLA-4’s external heatsinks do most of the work in getting heat away from the amplifier, in normal operation. A quiet, rear mounted variable-speed fan provides extra cooling of the amplifiers internal circuitry as needed.
