Have re-posted in this section to see if anybody can give me some more input about these Matamp Crossovers.
More of the Concert System cabs are with Tony and we have another batch on the way to us so no new boxes to look at yet. Anyway went and dug the Matamp analogue crossovers that will be controlling the rig out of the lock up yesterday. Got the top one from Ian (JBL Man), middle one from Ken (knet94) and the bottom one has just been lying around here for about ten years. Noticed for the first time that the bottom one has some fluted knobs. They look fine on the unit but not sure they are original.

Have had hardly any time to really look inside these, wonder what the link connectors are for on the left of the rear panel?

This looks like unbalanced ins and outs which I find quite surprising even though my SuperNova has unbalanced outputs. This could be a minor pain in the backside as a result.

This one has LD after the serial number (does this mean Line Drivers?) Looks like we could have balanced outputs which is a step in the right direction.

So although I would dearly love to keep an analogue signal chain it might not be possible if the amp racks are far away in the case of two of these crossovers. We will be using an ASS processor/filter too to control the subs at the beginning of this thread, that should take care of distance between FOH/Decks and the amp racks. Looks like we need to have a look at BSS/KT or even Lake to get a nice sounding unit. No point compromising at this stage of the game. So does anybody have any further info on these crossovers? Let the debate begin and all comments welcome.

Matt only made one series of this crossover, I think the only difference would be batch numbers, As well as fluted knobs, the bottom unit also looks like a slightly Silver. When I had mine I had 6db line drivers put on every output channel so that I could drive amps like Crown. ------------- http://www.facebook.com/tony.rossell.3" rel="nofollow - http://www.facebook.com/tony.rossell.3 |

saved my skin these photos appearing! I've been changing mine to balanced outputs and hadn't remembered the location of input on filter boards... would never have found it myself. anyways, balanced outputs required rewiring the power supply to have a centralised ground point for which i used a simple plastic screw terminal commoning block. Shield of outputs to chassis. +ve normal -ve added 100uf electrolytic caps with negative pin to a 93ohm resistor to match output impedance of line driver circuit then to my new ground. On my power amplifiers i have fitted 10K:10k transformers on the line inputs. (including 2 Quasar 1000s) Great crossover and no equivalent on market today really. |

the link connectors are to connect signal common to chassis and earth. this is often disconnected to as an unsafe fix to solve hum problems. or as with some Matamp products connected via a capacitor |

I had the ATC, it was designed by Tim Issacs I believe who was at ATC in the early days. This was bought direct from them to drive the 3 way ATC studio Monitors I had just built. It later formed the basis of one of the first SMS's that EAW used. It primary function was Studio work, so it was a very high spec. ------------- http://www.facebook.com/tony.rossell.3" rel="nofollow - http://www.facebook.com/tony.rossell.3 |

Pretty sure you need to hand that over to Paul Axis. He needs it to drive the valve system and will maybe swap with you.  ------------- music is the message |

| Sorry to revive an ancient thread but i found a Matamp crossover today in the scrap. I was wondering if it's still a decent unit or whether it's too noisy by modern standards? |

its a worthy relic from a bygon age ,probably one of the first active crossovers ,Matamp (Radiocraft Huddersfield,made Orange guitar amps ), We had one of those in plain silver and black with a H&H V800 rig , There is very little circuitry in them to go wrong ,But the push buttons were a liability , they sounded great at the time , but there are way better vintage options about (not Gauss or Ashley). The aformentioned ATC 3 way with optical limiters was one I used regularly before getting into BSS340s and 360s (which are still good if they are properly serviced) ------------- "couldn't we just like... use headphones?" |

If anyone could help, it would be Paul Axis from Huddersfield He and his mate Mac know the Matamp guy. He would certainly be able to point you in the correct direction

Heres a picture, not sure if it was modified or factory built like this Edit pics wont upload, its built in to a flight case with all the ins and outs on a separate 2u panel underneath. I’m not expecting anything crazy from it, just throwing together a system from various bits ive found like EAF KF650’s, a pair of TOA P300D’s and now need some kind of preamp

| obscure vintage gear tends to fetch decent prices. if you are more into using it as a simple solution i think you would be best to sell it as vintage gear and go for a simple "new"crossover like a dBX 223/234. likely will end for you with some pocket money besides a crossover which hasn't its own mind. |

| Yeh i know, ive got a BSS too but this looks like way more fun to experiment with. someones been messing around with it inside, do any schematics exist? |
