These two amps require a for use in mono-bridge mode. In an, you can see that the speakON connector is only using two wires.The for these amps says:Only the middle Speakon® jack can be used when operating in the Mono Bridged mode. (heavy duty mono bridge speaker cable provided.Why can't a standard 4-pole speakON connector be used? What is special about the output in mono-bridge mode that somehow causes the cabinet's speakON jack to no longer be correct for receiving signal from the typical 4-pole plug? A two channel power amp (such as one used for stereo amplification or mono bi-amping) is two power amps in one box. Each power amp will have its own output with two connectors, one positive and one negative.

On an amp with five-way lugs, banana plugs or similar outputs, it may look something like this:+ -+A single four-pole SpeakOn cable can carry both signals to a bi-amp capable cabinet with just one cable. Usually the two amps in a two-channel amp have the same rated output power. So, for example, you might have two channels that can put out 200 Watts RMS each into a certain impedance.What bridged mono mode allows is using both power amps to drive a single load, which gives you approximately double the power of using just one amp. So in the above example, while 'stereo' mode is two 200 Watt channels, bridged mono mode turns that into a single channel that can put about about 400 Watts RMS. In practice it's usually a bit less than the sum of the channels, maybe something like 380 Watts in this case.The way it does that is by connecting the amps together in series internally. The labeling on the outputs doesn't change, but if it could it might change to this:- 00 +The indicates the internal connection between the two poles.
So where before there were two pairs of positive and negative connectors, now there is a single positive connection and a single negative one, and also two connectors that should not be connected to at all. They are internally connected to each other.When wiring using banana plugs or spade lugs or something like that, you can just manually connect the wire ends to the correct terminals. With a SpeakOn cable, you can't change the internal wiring of the connector on the fly, so you have to use a cable that has been wired correctly internally. If you use a four-conductor cable, you risk the two connectors that should be connected to anything getting connected to something. That would be bad. So a two-conductor cable is the safe option.
It is safest to have a dedicated, specially marked lead just for use when the amp is bridged. I guess it would only be used for one speaker then. Or if two are used, again, another marked two wire cable would be a good idea. Till someone being helpful plugs in a 4-pole.Are all SpeakON connectors the same, so accidentally 2-pole can be connected to 4-pole? Doesn't sound like too good an idea if so.
Although once a 4-pole is connected to the dedicated 2-pole, it should be o.k. Assuming they're all connected properly at both ends?–Apr 29 '18 at 7:22.
Hi, I'm a newb!Been playing guitar for years, just starting to dig the bass thing. Bought myself an 88 G&L SB-1, black, maple neck, mojo all over, thing just freakin rocks!Bought a combo amp, too. It's a 1991 Ampeg SVT-15T. I played a ton of amps in this price range and this one killed em all. It sounds fantastic. I can't seem to find any info on the thing, is anyone here familiar with it?

I emailed Loud Technologies to get a manual, but haven't heard back yet.Thanks in advance! Glad I found this board, looks like a really great resource!
