MPN: Mini D2500
The Earthquake MiNi D Mono amplifiers are the most efficient class "D" series ever built. These amplifiers deliver unbelievable power despite of their super-compact size. With less than 2-inch tall and 7-inch deep, the MiNi D Mono amplifiers can be installed in tight spaces of the vehicle (under the seat, behind the back seat, etc.) allowing you to keep that valuable storage space in your vehicle. Earthquake Sounds 2nd generation series now has built in 5.2V USB connector to power a Bluetooth or WiFi module. One unique feature of the MiNi D Mono amplifiers is the BRIDGE IN/OUT that allows you to link 2 amplifiers together. Designed with patented Optical Control Circuitry, each of these amplifiers has a built-in protection fuse designed to handle 1 to 4-Ohm loads. In addition, the amplifier will automatically reset once the protection circuit is triggered. With the MiNi D Mono amplifiers, you won't have to sacrifice efficiency and space to get the immense power you need for your install. Better yet, due to its remarkable efficiency, you won't even need extra batteries for them.
Allows you to select the center frequency that you want to boost as well as the quantity. For most application, the best setting is at 1/2 turn (2 o'clock position).
Variable Subsonic Filter
Often used to protect speakers from harmful low frequencies and DC voltage. Often clipped low frequencies could have the same effect as that of DC input. The best setting for most systems is at 30Hz Highpass.
LPF (Low Pass Filter)
Often mistaken as crossover, the LPF is used to filter out unwanted mid and high frequencies, leaving the woofer to respond to low frequencies. For most subwoofer application, the best crossing point is about 1/2 turn (2 o'clock position).
Regulates the amplifier's sensitivity to match the signal output voltage of the audio source/head unit. It is not a volume control. The Mini D amplifiers have gain controls that are extremely sensitive and therefore, shoulb be adjusted with caution. When set at Min, it will need 4V to clip these amplifiers. But with a mere 1/4 turn, the amplifers can clip with only 0.5V.
