Pardon my lack of knowledge, talkbass gurus and wizards. I recently acquired an svt 5 pro with a hartke cab . It sounded AWESOME, but for the type of drop tuning we play in, I couldn't get the volume from the 4x10 due to it only having 400w. I traded STRAIGHT ACROSS for an ampeg svt 7 pro with an ampeg 8x10 (Gods be praised!) . I am curious ,what is the optimal way to connect it to the amp to the cab? I have never ran something mono bridged, and I don't know how to do it without damaging the amp. I have read the entire instruction manual, but it wasnt very clear on how to specifically do it. Any and all help is appreciated !
You just need to run a single speakon cable from the amp to the 810. The speaker outs on the amp are wired in parallel so it doesn't matter which one you use. See page 7 of the attached manual. The 810 is 4ohms. The SVT7-Pro can develop 1,000 watt at 4 ohms. Do not connect any more speakers as the 7-Pro is not rated for lower than a 4 ohm load.
Thank you . So, at any given time I use this amp, it's always pushing 1000w at 4 ohms? I was reading something in the manual about being 600w at 8 ohms . That's what was confusing me. The way I interpret that is that I should never connect anything less than a 4 ohm load to this cab . Is that correct?
So, in theory, if I wanted to connect , say, a 1x15 to this, while running something else , I would need two 8 ohm cabs , a 4 and an 8, ect?
Two 8 ohm cabs. A 4 and 8 ohm cab together will result in 2.67 ohms, which is out of safe operating range.
Yeah, but the cab you are pushing is a 4ohm cab, so the power will be maxed with the 810. One 4ohm cabinet = One 4ohm load. Just dont worry about it, and run the one cable.
When you connect two cabs with the same impedance in parallel, just divide the impedance by two. So if you have two 8 ohm cabs: 8/2=4 ohms. You can run two 8 ohm cabs with your SVT7-Pro. If you connect two cabs with different impedance in parallel, use this formula where Z is impedance: for example if you have an 8 ohm cabinet and a 4 ohm cabinet. Since 2.67 ohms is lower than 4 ohms, this combination of speakers should not be used with your SVT7-Pro.
