This auction is for pre-owned SoundStream MC 245 5-Channel 240 Watt Car Amplifier with Staggered Electronic Crossover (Made in USA) in good physical and working condition. The MC245 is conservatively rated at 240 watts. This power can be divided into; Five channels (4 x 35 watts, plus 1 x 100 watts), Four channels (2 x 35 watts, plus 1 x 90 watts, plus 1 x 100 watts), Three channels (2 x 90 watts, plus 1 x 100 watts). The design topology of this amplifier utilizes multiple Darlington output devices with a total output capability five times the total rated output of the amplifier. With such reserves and no current limiting, the amplifier operates without strain even at maximum output. Power, ground, and speaker connectors are rated to handle up to 80 amps and accommodate up to 8 gauge stranded cable. To prevent potentially damaging turn-on and turn-off thumps, a built-in delay circuit allows this amplifier to fully stabilize before sending the audio signal to the loudspeakers. The MC245 provides superior, non-intrusive protection from overheating in two ways: First, the Soundstream “Chassisink” has been custom designed to guarantee the lowest possible thermal resistance (maximum cooling), greatly reducing the possibility of overheating. Secondly, if this should occur, all Soundstream amplifiers incorporate a “Smart Power Supply” which temporarily modifies the power supply’s operating parameters, allowing the amplifier to run much cooler. Full output capability is restored once the amplifier returns to normal operating temperature. This entire process is automatic and inaudible. In the case of an actual amplifier malfunction, secondary fuses will shut down this amplifier in a conventional manner. Only premium parts are used, such as 1% metal film resistors, gold-plated input connectors, double-sided masked glass epoxy circuit boards and immersible sealed potentiometers. Input sensitivity is adjustable to match any tuner/deck, this amplifier can even be interfaced with most OEM speaker level signals. The MC245 incorporates built-in Staggered Asymmetrical Electronic Crossover. The high pass crossover is set at 180Hz with a slope of 6dB per octave. The low pass crossovers are set at 75Hz with a slope rate of 12dB per octave. By selecting two staggered frequencies, a dip in the acoustic response is created, which is most useful to compensate for common vehicle response peaks between these two fixed points.
Fantastico amplificatore soundstream old school, a 5 canali, con questo amplificatore si può pilotare l'intero impianto audio essendo anche molto flessibile come configurazione, nelle foto potete ammirare la prova svolta da una nota rivista audio con i valori e i grafici, basta osservare la tritim in regime impulso a 2 ohm risulta a una potenza di 80 w molto musicale in complesso con timbrica soundstream
