Amplifier Status Indicator
The alpha series amplifier have three different LED indicators. The first indicator is a power status for visual verification if the amplifier is OFF or ON. The second indicator is a clipping indicator, a extremely useful tool to tune the system. The third indicator is a protection status of the unit and will illuminate if any faults are present.
Nickel Plated Terminal Block
Nickel plated terminal blocks have been used on the Alpha series amplifiers. Since most cable is stranded, it is necessary to use terminal blocks to hold the strands together in fastening the connections. This type of terminal block maximizes the connection to deliver the voltage and current draw needed.
Extruded Heat Sink
Keeping the amplifier cool increases efficiency to an amplifier. To keep an amplifier cool is a combination of several things, but the most important two are power output and heatsink size. A heatsink size is not the only way to cool down an amplifier. Having increased the area of the heatsink increases the cooling dramatically. So, we extruded the heatsink so we can get the most advantageous area to aid the cooling efficiency.
Built-in Crossover
ALPHA4250 FULL RANGE DIGITAL AMPLIFIER features a built-in 12dB internal crossover for use with any type of loud speaker. Use the HP (high-pass) to adjust mid-range and tweeters or LP (low-pass) to adjust the woofers. If you have alternate external equipment to fine tune your system, just set the crossover to FLAT and you can equipped whatever processor you have.
