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 AmplifiersPower > 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 Features2/4 channel switch24dB/octave crossover4 Gauge power/ground terminalsAudiophile grade speaker connectionsMOSFET output stageMOSFET power supplyCEA-2006Power 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 InputsDifferential 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.DSMDSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.Dynamic Thermal ManagementHeat 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.MEHSA3MEHSA3(Maximum Efficiency Heat Sink Application--gen. 3) reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.NOMADNOMAD (Non Multiplying Advanced Decision) is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.Punch EQ2In 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 AvatarThese 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 MOSFETsRockford 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·anaTrans·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 SpecificationsNumber of Channels:4Rated Power:60W x 4 @ 4-Ohms RMS100W x 4 @ 2-Ohms RMS200W x 2 @ 4-Ohms bridged RMS2-Ohms x 2 bridged StableTotal Power:400 WattsDynamic Power:Front Channels90 Watts x 2 @ 4-Ohms 0 degrees Res154 Watts x 2 @ 2-Ohms 0 degrees ResRear Channels90 Watts x 2 @ 4-Ohms 0 degrees Res154 Watts x 2 @ 2-Ohms 0 degrees ResBridgeable:YesEfficiency (average):69% @ 4-Ohm68% @ 2-OhmCrossover Controls:Front High-Pass (HP): 50-500Hz 24dB/octave ButterworthFront Low-Pass (LP): 50-500Hz 24dB/octave ButterworthRear High-Pass (HP): 50-500Hz 24dB/octave ButterworthRear Low-Pass (LP): 50-500Hz 24dB/octave ButterworthTone Controls:Front Channels - Punch EQTreble: 0dB to +12dB @ 12kHzBass: 0dB to +18dB @ 45HzRear Channels - Punch EQTreble: 0dB to +12dB @ 12kHzBass: 0dB to +18dB @ 45HzSignal Input:Front Low level: 1 RCA pairRear Low level: 1 RCA pairSignal Output:n/aPower Input Connector:BlockPower Wire Gauge:4 AWGSpeaker Output Connector:Screw terminal barrier stripSpeaker Wire Gauge:8 AWG to 18 AWGHeat Sink Type:Cast aluminumCooling:ConvectionRemote Controls:Optional Remote Punch EQ (overrides built-in Punch EQ)Visual Indicators:PowerThermalProtectCircuit Topology Class:Class A/BFrequency Response:20Hz to 20kHz +/- 1dBShipping Weight:11.90 Lbs.
