Gold Member Username: N2audioLawrence, Ks USA Post Number: 1245 Registered: Mar-04 | ac volts 100-200v range |
|
Silver Member Username: Holt_champHtown, MI Post Number: 504 Registered: Oct-06 | how would you find the voltage to set the gains at...would it be sqrt(2500 x 2) for a kx2500.1? |
|
Gold Member Username: N2audioLawrence, Ks USA Post Number: 1249 Registered: Mar-04 | yup, 70.7v |

Silver Member Username: Holt_champHtown, MI Post Number: 507 Registered: Oct-06 | alright thanks alot!!! |

Platinum Member Username: GlasswolfWisteria, Lane USA Post Number: 11930 Registered: Dec-03 | nice idea, but every CD is recorded at a different reference level, unfortunately, so one may sound louder tahn another from a different label. This is why I use a pink noise generator to tune the system. |

Silver Member Username: Holt_champHtown, MI Post Number: 557 Registered: Oct-06 | what is a pink noise generator and where can i get one?? |

Silver Member Username: Holt_champHtown, MI Post Number: 560 Registered: Oct-06 | what is a pink noise generator and where can i get one?? and what would i set the amp to...like all the crossovers at 0 or somethin? |

Platinum Member Username: GlasswolfWisteria, Lane USA Post Number: 11947 Registered: Dec-03 | IASCA has a reference CD that has a pink noise track. that works very well. pink noise is just a signal delivering the same power to every frequency from 20-20KHz. It sounds like static, like a TV station with no broadcasting. C weighted curve pink noise takes into account the "curve" for human hearing, so the audible signal to the human ear sounds even across the spectrum, even though it actually isn't equal power throughout. It's an inversed bell-curve. bcae1.com has guides for setting amplifier gains. several in fact, if I recall. |

Silver Member Username: Illwill577Post Number: 108 Registered: Jan-06 | ok i have kx2500 so the gain should be sqrt(2500 x 2) for a kx2500. 70.7v <--- correct? but question. ive got my kx2500 to 2 15" l7s which are 1000rms with both total is 2000rms should i caculate my gain at 2000rms thats the subs or 2500rms the amps specs. i dont want to overpower the subs. i am just a little confused on which to set the gain by the amps specs or the subs rms because the amp can handle both subs rms |

Gold Member Username: N2audioLawrence, Ks USA Post Number: 1328 Registered: Mar-04 | I would use 2000 |

Gold Member Username: Nd4spd18Southeast PA Post Number: 2868 Registered: Jul-06 | ^^^^^ X2 With the build quality of L7s as bad as it is, I wouldn't put any more than their rated power on them. |
|
Silver Member Username: Illwill577Post Number: 109 Registered: Jan-06 | thanks alot i just didnt want to set the gain to high for the subs. |
