Soft limiting starts to occur when you approach the maximum output of your powered speaker allowing you to get more usable power out of your system without severe clipping. However, when you hear distortion, hard clipping or cutting out, reduce the overall level as you have exceeded the system's capacity. POWER/PROTECT When the system has been activated by the power switch, the LED will indicate GREEN. If the system should go into protect, the LED will indicate YELLOW which may occur if; a) one of the internal drivers short or b) if the power amp should require service. AC POWER The 742P is available in either 120V or 240V models. Always use dedicated circuits for powered speakers. Every Carvin SPSTM powered speaker is designed to be left on continuously in the case of permanent installations. ACTIVE MODE/PASSIVE MODE Normally this switch is left in the ACTIVE MODE setting, which uses the speakers internal amplifier to power the speaker. If desired, switch to PASSIVE MODE to bypass the internal amplifier and connect an external amplifier directly to the speaker through a 1/4" speaker cord. Note: Make sure to use the SPEAKER INPUT jack, and not the audio input jack for this purpose. The power cord does not need to be connected to the speaker in PASSIVE MODE- it will function like a regular, non-powered speaker. Passive Input Internal Amp Bypass speaker cable from outboard amp Switch ACTIVE MODE INTERNAL AMP 742P Read general information about the 742 enclosure for specs, warranty and precautions on the other side. REAR POWERED CONNECT PLATE SPSTM POWERED SPEAKER FEATURES Carvin's SPSTM SMART POWERED SPEAKERSTM are more than just another "power amp in a cabinet". They offer advanced electronics to perfectly control every speaker component. Woofers are power-managed through active filtering, allowing more low-end punch and preventing over excursion. The mid range has exceptional detail without harshness and the top-end remains crystal clear. The exclusive optoisolator limiter helps keep your peaks under control reducing distortion. Surprising transparency is delivered by pure, uncolored power from ultra-fast slew rate power amps. The heart of every Carvin SPSTM powered speaker is our exclusive Digital Powered Processing Amplifier (DPPATM), which is fundamentally, a very sophisticated delta-sigma V/A converter. The amplifier's THD is less than . 1% from 20-20k Hz. [. . . ] 0B MADE IN THE 742P SPEAKER INPUT 8 / 300W PASSIVE MODE !
