Features and Benefits

DC Offset Protection

This circuit protects the output of the amplifier against DC voltage. If for some reason DC voltage is detected at the output stage, the amplifier will shut down protecting the speakers from direct current.

Short Circuit Protection

The circuit protects the amplifier from damage due to a short found in the speakers or wiring. If one of the speakers or its wiring comes in contact with ground, the amplifier will shut down. To resume normal operation, correct the problem and turn the head unit off, then back on. The amplifier will reset and play again.

Thermal Protection

To protect the amplifier circuitry against damage caused by prolonged exposure to high temperatures, a thermal protection circuit is activated if the amplifier reaches excessively high operating temperature. Once the thermal circuit is activated, the amplifier will shut down to cool off. The amplifier will automatically turn back on once it cools down to a safe operating temperature.

Power Indicator

The diagnostic L.E.D. illuminates when the amplifier is on and receiving power.

Built-in Crossover

The “Speed Series” amplifiers include a built-in variable crossovers. The crossover features a variable frequency selection for precise low pass filtering for the SPA1000D, SPA1300D , SPA1600D and SPA1900D. The SPA90.2 , SPA90.4 and SPA150.4 also offer the same frequency selection with the option of low or high pass filtering.

Power and Speaker Distribution Blocks

Heavy gauge bare wire distribution blocks are provided for maximum power and signal transfer with minimal resistance.

Bass Boost (SPA1000D SPA1300D SPA1600D SPA1900D)

For added low frequency performance the amplifiers are equipped with a variable *0~18 dB bass boost @ 45Hz.

Line out

Full range line outputs have been provided for convenient connection to additional amplifi- ers in the system. The outputs are buffered to reduce signal loss. Please note that the amplifier’s input level adjusts these level outputs.

Power Fusing

This protects the amplifier against short circuits and excessive current.

Remote Turn-on

Automatically turns amplifier on when connected to the head unit’s remote output. The amplifier will turn on and off with the head unit to save current consumption. This control also operates the reset circuit for the amplifier’s protection. It must be connected with the head unit in order to reset protection circuits.

Adjustable Input Sensitivity

Allows you to fine-tune the level matching between your source and the power amplifier.
