I braved the cold and ran the LG1000 up in the garage yesterday. Firstly it works out of the box which is a good start. The I tried it into my pair of Epifani 1x12s, which are 8-ohms each, and then just one channel into Berg NV610, which is 4-ohms. Using the passive Duck Dunn I found I had to have the input gain wound right up to make the indicator lights operate. I haven't tried an active bass yet. The tracking of the volume control is certainly different to the Epi UL502. When driving the two 8-ohm cabs I needed to wind it quite a way up for it to be loud, but then I'm half deaf so it could have been VERY loud. Difficult to tell in the confines of the garage, the test will be when I use it at a venue. Difficult to comment on the Ashdown woolly thing but it's certainly not as clear as the UL502 although with the EQ out and no presets it sounded quite clean. I also took the opportunity to use an EBS Microbass as a pre-amp and go straight into the Fx Return, so bypassing the pre-amp. That sounded pretty good. Verdict. It works. I reckon I can eventually dial in my sound. It seems to prefer 4-ohm load to 8-ohm, probably more than other amps I've owned. It's a very light and cheap 500+500-watt power amp. It will make a good back-up and jam session backline amp. I think it would work very well into one or two 4-ohmcabs, preferably a pair of Berg NV610s of failing that a pair of UL310s.

How many speakers? Just the one? If so then connect the red or + terminal on the speaker chassis to 1+ on the Speakon and the other speaker terminal to 1- on the Speakon.

I believe that this '78 is Ash.

Have a look at [url="http://www.neutrik.com/Secure30/getMedia?encoding=ISO-8859-1&client=neutrik&saveAs=true&saveAsName=3%20Plugs+Jacks%20PG%20V7%202008.pdf&mediaPath=D:\DATA\CLIENT\neutrik\media\downloads\&mediaSavedName=Media_1475462113.pdf&contentType=application/pdf"]this.[/url]

[quote name='Merton' post='371318' date='Jan 5 2009, 08:04 PM']You kept that quiet [/quote] I had an rethink on my half rack stack you saw when you came over. I thought about an F1 but it's too wide and three times the price. The LG1000 is under 1/2 rack wide so it fits the bill nicely and will drive each of my 1x12s. Physically it'll fit well with the dBX compressor and the wireless monitoring. What I need now is a half rack flight case. If I'd have known that this was coming I'd have never have sold the UL310 and bought the NV610, I'd just have bought another UL310.

I received my LG1000 from Sounds Live last week but haven't had the chance to plug it in yet as it's too cold in the garage. I have a possible gig on Friday so I may well use it then.

Google wasn't massively helpful at establishing a point of sale for 1/4 jack connectors, where do you normally get them?[/quote] I tend to use Neutrik (because they are a well known brand) and get them from the Neutrik dealer from whom I used to buy miles of cable and thousands of connectors for building TV and radio studios and outside broadcast units. Amphenol have been supplying connectors to equipment manufacturers for donkey's years. They make a very compact and reasonable priced right-angle jack which I have been considering supplying. I bought some right-angle stereo plugs to evaluate and they seem very robust. You can get them from [url="http://uk.farnell.com/amphenol/acpm-rb/plug-6-35mm-jack-90deg-2pole/dp/1349048"]Farnell[/url]. Switchcraft are very good but more expensive than Neutrik.

[quote name='warwickhunt' post='369791' date='Jan 4 2009, 11:23 AM']IMHO Switchcraft are as good as Neutrik and I'd be happy with either of those.[/quote] Also Amphenol are very good.

[quote name='benwhiteuk' post='366586' date='Dec 30 2008, 08:41 PM']Looks good. There's also this that's rack mountable with a similar power output but at a slightly lower cost - [url="http://www.chemical-records.co.uk/sc/servlet/Info?ref=gbase&Track=DIMENSION3"]http://www.chemical-records.co.uk/sc/servl...rack=DIMENSION3[/url][/quote] Interesting find but judging by the weight I would not think it is Class D digital.

Whilst searching for info on Class D power amps I came across the Vestax VDA 1000. 2-channels, 500-watt each into 4-ohms, etc, or bridgeable at 100-watts into 8-ohms all for £249. Down side is that it's not rack.mountable. Details [url="http://www.vestax.com/v/products/active/vda1000.html"]at Vestax[/url] Available [url="http://www.htfr.com/more-info/MR244814"]here[/url] I know you can get an Ashdown LG1000 for £40 more including a pre-amp whch I suppose makes the LG even better value.

[quote name='bremen' post='359459' date='Dec 20 2008, 11:28 AM']Balanced cable is usually screened with foil or braid and has a twisted pair of inner cables. The idea is that any interference picked up on one wire is picked up equally on the other. The balanced input stage on the preamp rejects any noise that's common to both cores. Stereo cable ideally has a separate screen round each wire, so the two signals are kept separate. You can of course use a TRS jack for either.[/quote] Perfect explanation. If you use a balanced cable for stereo you will induce left/right crosstalk and the signal will be permanently and irrevocably impaired.

[quote name='jake_tenfloors' post='358930' date='Dec 19 2008, 04:20 PM']off topic/ If you use a stereo jack cable with and EBS head and active bass you can take the battery out [/quote] Neat idea but do you mean a stereo cable or a balanced cable? They are different. Also it must be dependant on how the bass is wired. If the bass uses the ring of the jack to connect the negative of the battery to ground, removing the battery would leave no connection to the positive side of the pre-amp. Do you have to fit something in place of the battery? Better still have you got a circuit diagram?
