SUBJECT: Old School Soundstream MC245 5 Channel amplifier ready for a new home.
ITEM BRAND & MODEL #: Soundstream MC245
CONDITION: 7.5 of 10 Really Clean minus a fin ding.
PRICE: Asking $375 Shipped CONUS
SHIPPING: Included UPS Ground CONUS
ADDITIONAL INFORMATION: 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 both amplifiers utilize 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, both amplifiers operate 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 these amplifiers to fully stabilize before sending the audio signal to the loudspeakers. The MC 140x/245 provide 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 our “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 these amplifiers 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 adiustoble to match any tuner/ deck, these amplifiers can even be interfaced with most OEM speaker level signals. Both the MC140” and MC245 incorporate built-in Staggered Asymmetrical Electronic Crossover. The high pass crossovers are set at 18OHz 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.
