Soundstream mc-140x Guía Del Usuario

The 

 is conservatively rated at 

 watts. This power can be divided into: Four

channels   x 35 watts), Three channels (2 x 35 watts, 1 x 90 watts), Two channels (2 x 90
watts).

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 

 

 100 watts).

The design topology of both amplifiers utilize multiple 

 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 

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 over-
heating. 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. 

 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 

 to match any tuner/

deck, these amplifiers can even be interfaced with most OEM speaker level signals. Both the

 and MC245 incorporate built-in Staggered Asymmetrical Electronic Crossover.

The 

high pass 

crossovers are set at 

 with a slope of 6dB per octave. The low pass

crossovers are set at 75Hz with a slope rate of 

 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
