Our Nexd™ Switching Technology Stems From Our Class D Expertise To Deliver Outstanding Fidelity And Efficiency, Leading To Compact Amplifiers That Deliver High Power And Exceptional Value. - Let´s Get A Little Nerdy... A Traditional Pwm Switching Amp Design Uses A Fixed Switching Frequency And Varies The Pulse Width Based Solely On The Audio Input Signal To The Pulse Modulator. This Basic Approach Assumes Some Ideal Conditions, Like A Rock-Steady Power Supply, That Do Not Necessarily Occur In A Real, In-Car Installation. Power Supply Sag With Signal Causes Distortion At All Power Levels With These Designs, Even Well Below Clipping. The Cure For This Is Feedback (A Corrective Signal Sent Back To The Input Side), But This Becomes Impractical As The Audio Frequency Increases, Making It A Good Solution For Band-Limited (Subwoofer) Amps, But Not For Full-Range Amplifiers. Differential-Balanced Inputs: - Most Audio Equipment Uses Single-Ended, Ground-Referenced Rca Jacks To Receive Audio Signals. This Means That The Rca Shield Is Connected Directly To Signal Ground. This Is A Simple, Cost Effective Input Design That Works Well For Short Runs In Noise Free Environments. In Noisier Environments, This Method Cannot Reject The Common Mode Noise That Could Be On Both Rca Conductors (Shield And Center Conductor). - By Having More Than One Chassis-Grounded Rca Shield On A Device, Single-Ended Input Designs Are Also More Susceptible To Ground Loops. If Noise Is Present On Both Conductors While The Shield Is Connected To Ground, The Input Amplifier Will Amplify The Noise Relative To The Grounded Rca Shield. When There Are Multiple Rca Connections Or Any Other Conductors Subjected To A Magnetic Field, This Will Cause A Difference In Potential Across The Rca Loop To Be Amplified At The Grounded Rca As Noise (A Classic Ground Loop). - Jl Audio’S Differential-Balanced Input Circuits Measure The Center Pin Of The Rca Connection Relative To The Rca Shield, Even When The Shield Is Not Connected To Ground, And Even When The Voltages At Both Conductors Are Moving Relative To Ground. Because Both The Center Conductor And The Shield See High Impedance To Ground At The Input, A Ground Loop Cannot Be Formed, As There Is No Current Flow To Induce A Voltage As Noise. This Works Equally Well With Differential-Balanced, Or Unbalanced Signal Sources, Making This Input Architecture Compatible With All Standard Car And Marine Audio Equipment, Using Standard, Unshielded, Twisted-Pair Rca Cables. No Special Cables Are Required, Unlike The Fully Balanced Connections Used In Professional Audio.
