bassman619 Posted August 23, 2013 Report Share Posted August 23, 2013 Amp is memphis mc1.1500 ..this is something I dnt understand here. It has a gain control as all amps do but there is also a switch that slides back and forth that says input sensitivity. Left side says 1x. Right side says 10x. Can some one explain to me what does it control and where should I have it set? My settings on amp are as follows. Lpf_80hz ..gain 0.7v which results in pulse of 28-40volts outputting from the speaker wire connections. Which is making 1200-1500watts rms..Subsonic set at 37hz..bass boost 1/3 ..enclosure is tuned to 38hz. Head unit bass curve set at 80hz..so whats up with the input sensitivity switch?

Devilsniper Posted August 23, 2013 Report Share Posted August 23, 2013 The gain control adjusts the amount of signal required to drive the amplifier to full output .With the gain at maximum (full clockwise rotation), less signal voltage Is required to drive the amp to full output. With the gain at minimum (full counter -clockwise rotation), more signal voltage Is required to drive the amp to full output.The gain Is adjustable from either 1OOmV-1Vor 1V-1OV range. With Is Selected with the lox multiplier switch. Put the Is with In x1 to select either 1OOmV-1V or x 10 to select 1V-10V.

bassman619 Posted August 23, 2013 Author Report Share Posted August 23, 2013 But if I change it to 10x then whats going to be different? You need trunk space to get groceries and shit...bitches love groceries Link to comment Share on other sites More sharing options...

ROLEXrifleman Posted August 23, 2013 Report Share Posted August 23, 2013 Don't over complicate this. What is your voltage output from your deck ( or source) feeding the sub? That voltage is what you should set your switch to. SO..... If your deck outputs LESS than 1 volt switch it to 1x If your deck outputs ABOVE 1 volt and less than 10 set it to 10x Rolex you sicken me.

rockFord_Expedition Posted August 23, 2013 Report Share Posted August 23, 2013 Very different. 1x takes the input sensitivity numbers at face value. 10x multiplies them by 10. Do you have a way to check the voltage of your RCA's? Does the gain have numbers that coincide with the position of the dial?
