Offering superb sound quality, the ART SLA-4 studio linear power amplifier delivers the clean power you need for any professional audio application including project or professional studio environments or commercial sound installations.

The SLA-4 is a true four-channel amplifier in a single rack-space that can be switched easily from Multi-channel, Stereo and Bridged Mono Modes. Separate mode 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.

Designed for long-term reliability in any audio application, the SLA-4's output is fully protected from short circuits. An ultrasonic network decouples RF from the output and helps keep the amplifier stable with reactive loads. The SLA4 is stable into loads as low as 2 ohms (stereo mode) or 4 ohms (bridged mode) making it ideal for virtually any installation application or complex system configuration.

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 high or low levels depending on the amplifier's cooling needs.

1/4-inch TRS and Euroblock balanced inputs as well as multi-way output binding posts are ensure the SLA4 can be quickly and easily tied in to any system without modification. A simple to install tamper proof cover is included.

We chose this amp because it has four channels and excellent sonics, and, for it's versatility. We run three channels, two bridged to house main (8 ohms) and the other two individually, as a monitor line (4 ohms) and a feed to another room (6.2 ohms). On rare occasion the bridged channel gets pushed to within 6dB of maximum. The disappointment we had with this amp was with the cooling fan. The operating environment is usually quiet and the high pitched whine from the fan (>45dBA) was loud enough to be bothersome anywhere in the room. At first I just disconnected the fan and placed the amp vertically to enhance convection which worked well - it got warm but not hot. After a while I bought a quieter fan and modified the control circuitry with thermistors on the output devices. That worked great. At idle the fan is just barely rotating, almost inaudible and gradually increases speed as the amp gets warmer. It has never gotten hot. This is how it should have been engineered to begin with. Also, what's with the Euroblock input terminals? Why not XLRs instead? Overall we are quite satisfied with this little guy, after the mods.

I use this amp to run 4 separate stage monitor channels through 4 YX-10 speakers. There are times when the amp is working hard, but never tapped out. The fan runs quite a bit in this case, but I don't find it as noisy as other reviewers of similar SLA amps have noted. The fans are quieter than the 2 PCs at our board. Good value! Use both front and rear mounts to keep the front panel from staining.
