These ultra-efficient, super compact amplifiers are designed with Massive Audio’s exclusive \"Massive Core\" which adds tons of headroom for clean, undistorted, pure sound.\u003c\/p\u003e\n\u003cp\u003eThe \"Massive Core\" power supply with oversized toroids and transformers delivers plenty of current to drive even the most demanding woofers and speakers. Top-quality parts and construction ensure years of reliable, trouble-free service. Four-layered circuit boards, with surface-mount computer-assembled parts, are tested as they are placed on the board, to help optimize the signal paths and minimize the need for point-to-point wiring while keeping the board temperature even for more predictable operations.\u003c\/p\u003e\n\u003ch5\u003eManuals \u0026amp; Downloads\u003c\/h5\u003e\n\u003cdiv class=\"support-data\" style=\"display: block;\"\u003e\n\u003cp\u003e\u003ca rel=\"noopener\" title=\"Massive Audio GT \/ GTR Amplifier Manual\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0658\/1297\/files\/GTR_GT_MANUAL-2025.pdf?v=1737655265\" target=\"_blank\"\u003eGT \/ GTR AMPLIFIER MANUAL\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch5\u003e \u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e2 Ohm Stable Class D Digital Design\u003c\/li\u003e\n\u003cli\u003eMil-Spec Multi-Layer PCB with SMD Parts\u003c\/li\u003e\n\u003cli\u003eBuilt-In Noise Reduction Circuitry\u003c\/li\u003e\n\u003cli\u003eFull MOSFET with High-Grade \/ High-Speed Switching\u003c\/li\u003e\n\u003cli\u003eBuilt-In Auto Sensing Turn-On via RCA Inputs  \u003c\/li\u003e\n\u003cli\u003e12V Remove Output for External Devices (when Hi-Level is used.)\u003c\/li\u003e\n\u003cli\u003eNext-Generation Advanced 5-Way Protection Circuitry\u003c\/li\u003e\n\u003cli\u003eWorld Wide Standard Compliant\u003c\/li\u003e\n\u003cli\u003e4 AWG Recommended Input\u003c\/li\u003e\n\u003cli\u003eClip LED Indicator\u003cbr\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/h5\u003e\n\u003ctable border=\"0\" cellpadding=\"0\" cellspacing=\"0\" width=\"612\" style=\"border-collapse: collapse; width: 460pt; height: 299px;\"\u003e\n\u003ctbody\u003e\n\u003ctr height=\"23\" style=\"height: 23px;\"\u003e\n\u003ctd height=\"23\" width=\"306\" style=\"height: 23px; width: 230pt;\" class=\"xl63\"\u003e2 Ohm RMS\u003c\/td\u003e\n\u003ctd width=\"306\" style=\"border-left: none; width: 230pt; height: 23px;\" class=\"xl63\"\u003e120w x 4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"23\" style=\"height: 23px;\"\u003e\n\u003ctd height=\"23\" width=\"306\" style=\"height: 23px; border-top: none; width: 230pt;\" class=\"xl63\"\u003e4 Ohm RMS\u003c\/td\u003e\n\u003ctd width=\"306\" style=\"border-top: none; border-left: none; width: 230pt; height: 23px;\" class=\"xl63\"\u003e75w x 4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"23\" style=\"height: 23px;\"\u003e\n\u003ctd height=\"23\" width=\"306\" style=\"height: 23px; border-top: none; width: 230pt;\" class=\"xl63\"\u003e4 Ohm Bridged\u003c\/td\u003e\n\u003ctd width=\"306\" style=\"border-top: none; border-left: none; width: 230pt; height: 23px;\" class=\"xl63\"\u003e230w x 2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"23\" style=\"height: 23px;\"\u003e\n\u003ctd height=\"23\" width=\"306\" style=\"height: 23px; border-top: none; width: 230pt;\" class=\"xl63\"\u003eInput Level\u003c\/td\u003e\n\u003ctd width=\"306\" style=\"border-top: none; border-left: none; width: 230pt; height: 23px;\" class=\"xl63\"\u003e310mV ~ 7V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"23\" style=\"height: 23px;\"\u003e\n\u003ctd height=\"23\" width=\"306\" style=\"height: 23px; border-top: none; width: 230pt;\" class=\"xl63\"\u003eFreq.
