Potencia Rockford Fosgate 800.4 De La Vieja Escuela

vendo potencia rockford fosgate en excelentes condiciones, nunca reparada, mueve lo que quieras, varios juegos de componentes, subwoofers, etc. 4 canales puenteables 100rmsx4 a 4ohms, 200x4 a 2ohms y 400x2 a 4ohms una bestia, son rms de rockford no de cualquier marca, la distorsion es minima 0.05thd a los rms que declara, o sea una calidad impresionante, el unico detalle que tiene es un potenciometro de punch bass que le falta un pedacito de plastico pero se puede operar tranquilamente, cuesta un poco mas nada mas.

puedo tomar algo de audio de marca

Features

TRANSana (TRANSconductance Active Nodal Amplifier): TRANSana is a circuit that allows the audio signal to pass through the amplifier at low voltage. The signal is directly level-shifted to the fixed high voltage rails via a pair of drive transistors. Signal linearity is assured by an active node formed  by the drive transistors at ultrasonic frequencies. The result is crystal clear sound quality, even at high volume levels.

MEHSA (Maximum Efficiency Heat Sink Application): MEHSA is a Rockford Fosgate proprietary process that increases the heat transfer from the MOSFET devices to the heatsink. The multi-layer insulated metal MEHSA substrate operates with minimal thermal resistance, spreading heat both downward and outward to quickly dissipate heat from each device across the heatsink. This allows greater power output, enhanced thermal stability, and maximum reliability.

TOPAZ (Tracking Operation Pre-Amplifier Zone): TOPAZ is a circuit that simply eliminates noise. The TOPAZ circuit allows the amplifier ground to move with the source unit ground, creating a "noise elimination" zone just before the preamp section. If there is any noise in the ground coming down the RCA line to the amplifier, TOPAZ amazingly tracks it down and eliminates it. The result is a 30-40dB improvement of the isolation between input ground and chassis ground. 

DSM (Discrete Surface Mount): In the manufacturing process high speed robotics are used to place 0% tolerance resistors and large board traces providing greater reliability and efficiency.

NOMAD (NOn-Multiplying Advanced Decision): NOMAD is an intelligent protection circuit that uses an analog computer to make real time decisions regarding temperature, voltage, current and impedance. The unit is protected without limiting sound output unless needed.

Internal Crossovers: There are two  internal crossovers (one for the front and one for the rear) channels. Either crossover may be turned to Low pass, High pass or the crossover can be turned off for full-range output.

Crossover Frequency: The crossover frequency control is variable from 50Hz to 210Hz for either the front or rear crossover.  The slope of the crossovers is 12dB per octave.

RF Center Badge: Upon arrival, the RF center badge is not adhered to the amplifier. For installation flexibility, the badge can be rotated 180 degrees. Once you've decided in which direction the badge looks best for your installation, the peel-and-stick backing on the badge can be used to attach it to the amplifier.

Variable Punch Bass: Allows you to correct acoustical deficiencies by helping reproduce full range sound without adding excessive boost.  There are two controls (one for the front and one for the rear channels) which allow you to vary bass at a fixed 45Hz frequency by 0 dB to +18 dB.

Controls

Left Side Of Amplifier:

• Two Crossover Switches : Allows you to select full range,  hi-pass or low-pass crossover operation at 12 dB/Oct.
• Two Crossover Frequency Knobs: Allow you to continuously vary the crossover frequency for either crossover from 50Hz to 210Hz.
• Front Gain: This variable gain control allows you to adjust the output level of the front channels
• Rear Gain: This variable gain control allows you to adjust the output level of the rear channels
• 4-2 Input switch: Allows the unit to be driven with either 1 or 2 pairs of inputs without requiring the use of "Y" connectors.
• Punch Bass Knobs: Two knobs (one for the front and one for the rear channels) allow you to continuously vary bass boost centered at 45Hz by 0dB to +18dB. 

Inputs and Outputs

• Input: Two pairs of Gold-plated RCA jacks (one for front and one for rear channels)
• Output: One pair of Gold-plated RCA jacks (This is a full-range, pass-thru output) 
• High Level Inputs:  Two Molex plug inputs for included harnesses
• Speakers: Gold-plated set screw for four loudspeakers and accept wire sizes from 8 AWG to 18 AWG
• GND (ground): Two gold-plated set screw terminals; each terminal will accept 8 gauge wire
• B+ (power): Two gold-plated set screw terminals; each terminal will accept 8 gauge wire
