How To Set Amplifier For Subwoofer

Amplifier Settings

Updated one year ago past Jordan Alexander

Monoblock Amplifiers

The settings below are common settings found on monoblock amplifiers. While every monoblock amplifier on the market may not have all of these settings on the same amplifier, information technology is of import to sympathise the office of each setting to achieving the best settings for your build.

Low Pass Filter (LPF)

In its nigh basic explanation, the Depression Pass Filter (LPF) setting on your amplifier acts as a filter that blocks frequencies in a higher place its set level. For example, if your LPF is set for 125 Hz, only frequencies below 125 Hz will be allowed to pass through the amplifier to the speaker or subwoofer.

Subsonic Filter

The Subsonic filter on your Skar Audio amplifier acts very similarly to the Low Pass Filter, but in the opposite manner. The Subsonic Filter will block frequencies beneath its fix level. For example, if the Subsonic Filter is set to thirty Hz, only frequencies above xxx Hz will be passed through the amplifier to the speakers or subwoofers.

Bass EQ

The Bass EQ switch on your amplifier is meant to heave depression-end frequencies. In most applications, this switch should exist left in the off, or 0 dB, position. Nosotros recommend only using this when your amplifier has been properly tuned to do and so. Improper use of the Bass EQ switch can event in impairment to your subwoofer which may disqualify for coverage under warranty.

Gain

Opposite to popular conventionalities, the gain knob on your amplifier does not act in the same style every bit a volume knob (i.e. Turning the gain halfway up does not mean the amplifier is going to produce half its intended power). The role of the gain knob is to maximize the signal to noise ratio by matching the amplifier'due south input sensitivity to match the output voltage to the preceding source unit.

Stage

The purpose of the Phase setting is to change the polarity/management of the sub(s) running off the amplifier. Typically, this setting volition be used in most cases for 2 reasons:

Your gear up has your subwoofers inverted and you need to change the style in which your subwoofers play (inward vs. outward)
Y'all are using a multi-subwoofer and multi-amplifier set up in which the subwoofer(s) playing off of one amplifier is playing outward and the subwoofer(s) playing off of some other amplifier are playing inwards.

Across the ii reasons mentioned above, this setting is not going to need to be used.

Master/Slave Switch

The Principal/Slave Switch is normally establish on amplifiers that have the ability to be strapped. Essentially, when harnessing the power of two like amplifiers (i.e. Harnessing the power of (2) SKv2-4500.1D to become an output of 9000W RMS at 2 Ohm), one amplifier will be set to Principal and the other will exist ready to Slave.

For more than information on how to set this upwards correctly, please use the instructions located in the manual provided with your amplifier.
