ART SLA4 4-Channel Studio Linear Power AmplifierOffering 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
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.

Useful, simple room divider
Color: White, Size: 4 Panel Basic
All the pieces were accounted for, and some even had extra pieces, maybe just in case they need changing. It was a bit like putting together a piece of IKEA furniture, though I went slower than usual so as not to make any mistakes. It wasn’t too hard to put together myself, and helps give my studio apt a feeling of space and privacy for my bed. I only wish it had a lovely Japanese design on it, but it does amazingly seem to match the wall color.

Multi purpose divider
Color: White, Size: 4 Panel Basic
I am excited this divider is being used to block off a portion of the dining room where I stored extra supplies. It looks nice!
