The STA-500 is a rock-solid and widely applicable stereo PA amplifier, designed for a variety of audio applications. Whether it concerns a fixed installation in a catering facility, a club building or a mobile DJ set: this amplifier delivers the stable performance you need. Equipped with active fan cooling and an extensive electronic protection circuit, the STA-500 remains cool and reliable even during prolonged and intensive use.

Thanks to the separate volume controls per channel and the handy clip LEDs, you always have full control over your sound system and prevent overload.

The most important advantages at a glance:

• Optimal Temperature Control: Powerful fan cooling for continuous performance under high loads.

• Advanced Security: Built-in circuit with LED indication against short circuit, overheating and DC voltage on the outputs.

• No Power-on Blast: Integrated speaker power-on delay protects your precious speakers at startup.

3. Long Product Description (The Complete Story)

Versatile powerhouse for general applications: The STA-500

The STA-500 Stereo PA Amplifier is the ideal partner for anyone looking for a no-nonsense amplifier for general use. Thanks to its robust construction and universal character, this power amplifier is perfect for both background music and more powerful sound systems in cafes, schools, fitness centers or home studios.

Full control and fine tuning

There are two independent volume controls (level controls) on the front of the STA-500. This allows you to adjust the volume of the left and right channels separately and accurately down to the decibel. To ensure that the connected audio system does not become overdriven, each channel is equipped with a bright LED clip indicator. As soon as the signal threatens to distort, the LED warns you immediately, so that you can adjust the volume in time.

Maximum security for amplifier and speakers

Security comes first with the STA-500. The amplifier is equipped with an intelligent protection circuit that continuously monitors the status of the device. In the unlikely event that a short circuit occurs, the temperature rises too high or DC fault voltage occurs on the outputs, the amplifier will intervene immediately to prevent damage. This is immediately made visual via an LED indication on the front panel. In addition, the automatic switch-on delay prevents that dreaded loud 'bang' over the speakers when you switch on the set.

Smart solutions for installers

A known problem when connecting multiple audio devices is the so-called ground loop, which results in an annoying hum. The STA-500 effectively solves this with a Ground Lift switch on the back. This allows the signal ground to be easily disconnected from the housing ground to make the hum disappear immediately. Add to this the active fan cooling, and you have an amplifier that continues to perform quietly, cleanly and reliably under all circumstances.
