rockford fosgate power t400-4 400 watt multi channel amplifier
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 ensures it can be installed in any location -- like under front seats . rockford fosgate power series amplifiers power gt size . these compact amps deliver the same gut wrenching power as its big brother but their chassis designs are up to 40 smaller . dtm dynamic thermal management allows efficient heat transfer that minimizes physical size and enables installs under seats and other compact areas when abundant power is required . 400 watt 4-channel amplifier . click to enlarge . perfect for front rear fading stereo systems or when dedicated amplification is required between front stage speakers and rear subwoofer s . click to enlarge . small chassis designs with serious power . click to enlarge . t400-4 features 2 4 channel switch 24db octave crossover 4 gauge power ground terminals audiophile grade speaker connections mosfet output stage mosfet power supply 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 input circuitry measures the voltage of both the and - input signal . the circuitry subtracts the voltage common to both conductors noise resulting in only the clean signal . this allows only clean signal to enter the amplifier . dsm dsm utilize 1 tight-tolerances improving efficiency of the circuit decreases cross-talk from other discrete components and lowers operating temperature . dynamic thermal management heat is often inefficiently dissipated across a heatsink causing hot spots . rockford fosgate engineers have developed an award winning cooling design called dtm . this patent pending design seamlessly manages the output of power supply temperatures while evenly distributing the excess heat across the entire amplifier . mehsa 3 mehsa 3 maximum efficiency heat sink application -- gen. 3 reduces mosfet temperatures lowers distortion increases durability and prolongs the output device life span . nomad nomad non multiplying advanced decision is a real time analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances . punch eq2 in the early 70 s jim fosgate studied the acoustical properties of automobiles . utilizing a real-time analyzer and pink noise he would graph out the acoustical characteristics of each car he tested . jim discovered three problems that were common to all cars a midbass hump between 100-275hz a steep roll-off of high frequencies from 2khz up to 20khz and reduced bass response below 50hz . the punch eq on-board equalization circuit helps correct for these acoustical deficiencies in the listening environment . when set to low-pass lp operation it becomes a variable bass boost . when set to high-pass hp operation it acts as a variable mid-bass and treble boost . when set to all pass ap operation both bass and treble frequencies are boosted . rockford fosgate avatar these avatars are a personal signature from the rockford fosgate team member who designed and engineered this fanatic product . this statement illustrates rockford s commitment to being designed and engineered in the u.s.a. 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 trans conductance active nodal amplifier 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 . t400-4 specifications number of channels 4 rated power 60w x 4 4-ohms rms 100w x 4 2-ohms rms 200w x 2 4-ohms bridged rms 2-ohms x 2 bridged stable total power 400 watts dynamic power front channels 90 watts x 2 4-ohms 0 degrees res 154 watts x 2 2-ohms 0 degrees res rear channels 90 watts x 2 4-ohms 0 degrees res 154 watts x 2 2-ohms 0 degrees res bridgeable yes efficiency average 69 4-ohm 68 2-ohm crossover controls front high-pass hp 50-500hz 24db octave butterworth front low-pass lp 50-500hz 24db octave butterworth rear high-pass hp 50-500hz 24db octave butterworth rear low-pass lp 50-500hz 24db octave butterworth tone controls front channels -
