ROCKFORD FOSGATE (T600-4) POWER 600 WATT 4-CHANNEL AMPLIFIER T600-4 The Power T600-4 is a 4-channel amplifier capable of producing 150 Watts into each of its four channels at 2-Ohms. The T600-4 can run a 4-way full-range system or use component speakers on the front with subwoofers on the rear. The T600-4 amplifier offers the perfect balance of power output and compact design required for high performance audio systems. The 4-channel configuration allows fine tuning adjustments between front stage component systems and rear surround speakers. The built-in crossover also allows the rear channels to be configured for running one or two subwoofers. FEATURES: 24dB/octave crossover MOSFET output stage 4 Gauge power/ground connectors 2/4 channel input switch MOSFET power supply Audiophile grade speaker connections RCA pass-thru outputs TECHNOLOGIES: DSM: DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature. Engineered In The USA: These Avatars are a personal signature from the Rockford Fosgate team member(s) who designed and engineered this fanatic product. This statement illustrates our commitment to being Designed and Engineered in the U.S.A. DTM: Dynamic Thermal Management evenly distributes excess heat across entire amplifier heatsink. MEHSA3: MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span. NOMAD: NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances. CTA-2006 Compliant: Power ratings on Rockford Fosgate amplifiers conform to CTA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings. Punch EQ2: Onboard equalizer with up to +18dB @ 45Hz and/or up to +12dB boost at 12kHz. TRANS•ana: Trans•ana is a Class A/B topology that simplifies the signal path of the amplifier allowing the signal to travel through the amplifier at a lower voltage. The result is greater reliability and exceptional sound quality. TO-247 MOSFETs(left-OLD | right-NEW): Rockford Fosgate amps use custom TO-247 MOSFETs. These have 60% more metal tab area for more power capacity, lower impedance and improved heat dissipation over traditional TO-220 MOSFETs found in competitor amps.
