Description The T400-4 amplifier is perfect for front/rear fading stereo systems or when dedicated
amplification is required between front stage speakers and rear subwoofer(s). Thanks to the
Dynamic Thermal Management, the small chassis design insures it can be installed in any
location – like under front seats.
CEA-2006
Power ratings on Rockford Fosgate amplifiers conform to CEA-2006 industry standards. These
guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated
marketing ratings.
Differential Inputs
Differential inputs eliminates noise picked up the signal cable.
DSM
DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from
other discrete components and lowers operating temperature.
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.
Punch EQ2
U.S. Patent (Patent Pending)
Onboard equalizer with up to +18dB @ 35Hz and/or up to +12dB boost at 12kHz.
TO-247 MOSFETs
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.
TRANS-ana
Trans-ana 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.
Features:
2/4 channel switch
24dB/octave crossover
4 Gauge power/ground terminals
Audiophile grade speaker connections
MOSFET output stage
MOSFET power supply
