New Exodus JR Filters

Kevin P · « **on:** 14 Oct 2004, 11:18 pm »

We have some updates to the JR Filter that are worth noting.

#1. New PCB which allows us to offer the assembled version at the price of the old kit. (labor cost is signficantly reduced).

#2. The PCB has an option for a parrallel inductor network for high current applications. It can be populated for a number of configurations so there is plenty of flexibility in layout.

#3. All boxes are now powder coated. The finish is excellent and a big improvement over either paint or anodizing.

#4. Options for various outlet choices allow for total customization.

#5. All assembled filter outlets will come with discounted Asylum Cable options. Alternately or our new "Red Coat" Belden 83803 based power cable is offered.

Pricing for the two outlet version start at $145 assembled & progress upward from there based upon outlet options, filter networks & power cord choice.

I'll drop some pictures on here and add more as I get them taken.

Both high current (parallel inductors) & low current sections. This allows isolating digital equipment which often have noisy switching power supplies across two filter networks.

Kev,
What is the pricing for the options??

Kevin P · « **Reply #2 on:** 15 Oct 2004, 02:23 pm »

I'm working on it.... the web page should be done today. I'll give you some rough details.

As with anything you can get really crazy with options. The FIM outlets alone cost $68 each and three of them would be more than the cost of the entire unit. Any of the Acme outlets are also options and drive up the price based on the model selected.

Two Outlet Version with one filter network: $145 Assembled
P&S 5252-I Outlets & no power cord.

Assembled 6ft Asylum Cord add: $55
Assembled 6ft Red Coat (Belden 83803) add: $135
Second Filter Network add: $15
Parrallel Network add: $27
Upgrade to 5262-AW outlets add: $8

Three Outlet Version Base Price with one filter network: $165

Assembled 6ft Asylum Cord add: $55
Assembled 6ft Red Coat (Belden 83803) add: $135
Second Filter Network add: $15
Parallel Network add: $27
Upgrade to 5262-AW outlets add: $12

We can also leave out the circuit breaker & Varistors for no charge. The price doesn't change because the breaker has to stay in place to fill the hole in the chassis. We also have built these as straight outlet boxes without the filter network period. It would be a straight power strip using 12AWG wire. Removing the filter network completely brings the price down about $35 from the base price above.

All of these are fantastic bargains for what you get. The quality is really top-notch and the parts used are much better quality than used in products anywhere near this price point. The parts cost has gone up due to powder coating the new PCB & assembly but our price has gone down. Overall.... these should be a big hit.

Nice job! It looks GREAT, and bet it sounds just as good

Thanks Vinnie.....

How they sound depends on a lot of variables. Our build quality is top-notch though and we are constantly improving everything we make.

We feel the current version of the filter is competitive in price with many of the mainstream mass-market products while using parts that are much higher in quality.

Kev,
What does the Second Filter Network and Parrallel Network do/add to the the overall performance?
Thanks

The second filter allows extra isolation from RFI line noise. Poorly designed switching power supplies in digital equipment are often the largest source of AC line RFI. Having a single filter on the offending piece of equipment can help drastically cut the RFI from entering other equipment. The extra filter further cuts RFI from the digital equipment by effectively having two filters rather than one between pieces of equipment. It provides a separate filter for the other components so that line noise generated by outside sources is filtered.

The parallel inductor section provides a single high current network for use with power amps and other high current devices. Alternately we can leave one outlet unfiltered for those who like to run the power amp without a line filter. Having three different outlets allows the user to experiment with various filtering options to objectively see which configuration works best with their system. The flexibility of this design is one of its greatest strengths because we cannot always predict what changes on the AC side of things will do for subjective preferences. Much of this is still voodoo so giving people advice on what is going to sound the best is tricky. Our advice is to have multiple options so that you can experiment within the context of your system to see what sounds the best for your given situation.

Ok.... the page for the 3-outlet version is done. The price came in lower than I have listed above after calculating my cost.

I've also finished a page on the new power cord using Belden 83803.

The unit looks nice and I am interested, but not sure about filtering. I would want to use the unit for two power amps, crossover and a CDP. Filter, or no Filter?

Kevin P · « **Reply #9 on:** 27 Nov 2004, 02:32 pm »

With the amps you need to experiment. Many people are convinced you shouldn't have a filter between the amp & the outlet. I have yet to use it with an amplifier where it was a problem but come to your own conclusion by trying it both ways. Plug in everything to the JR Filter and then try it with the amps running straight to the wall. If you notice the filter causes a negative effect on your amplifiers just don't run them through the filter.

Assuming the rocker switch is an on/off and not a circuit breaker

Does it matter which way you use it?

Plug everything in, leave them turned on and use the rocker for on/off

plug everything in, leave the rocker on and use the individual component on/off

plug everything in, use the individual component on/offs and the rocker on/off

Kevin P · « **Reply #11 on:** 7 Dec 2004, 08:02 pm »

The rocker is for a 12A circuit breaker... not power on/off.

Having a single switch for powering on/off all the components can be problematic. Some equipment powers up more gracefully than others and depending on the equipment, you can have noise & transients in the speakers during on/off. It makes the most sense to me to use the on/off provided by the manf. of the equipment.

So the filter is always "On"?

How much of a power draw is it?

Kevin P · « **Reply #13 on:** 7 Dec 2004, 11:04 pm »

It is a totally passive circuit so it doesn't draw any power.

last question

How long for delivery?

Appreciate the help

Just a suggestion, but I have implemented my own version of the JR filter as follows:

all separately choked outlets, 4 of them
1 one also has the JR digital isolation transformers after the chokes for digital devices (very highly recommended)
2 are just standard choked outlets for source components
1 is for the amps, using a DPDT switch to select between un-choked or parallel choked

I have found that my amp prefers unchoked with extra X rated capacitors across the + to - (aka Audio Prism Quiet line filter).

Just a thought that you may want to consider for those who are unsure about what their amp might prefer. A DPDT switch is a fairly simple solution and allows them to A-B much easier. Unfortunately if the amp prefers no chokes then they have paid for those extra parallel chokes for no reason (and the chokes are the expensive part of this product).

Enjoy,
Bob

If you can build something you have all kinds of opportunity to experiment and play. It really is impossible to tell people what is going to sound best in their system simply because power conditions vary & all equipment responds differently to RFI on the line.

Typically our turn-around time on a filter order is 24-48 working hours (not weekend hours).

I see your asking about other solutions on the general board. If you want the full monty for power filtering I'd recommend the Furman IT Reference. I've just become a dealer because they offer what I feel is one of the best engineered solutions on the market. They are the largest company in the world doing power conditioning and they have the resources and engineering talent to do a lot of things that the audiophile brand companies cannot.

The RI-1220 is all the unit you will ever need. Take a look at their training video for more details.

I am looking for a PC to use with my vintage amp pre amp set up. Most imporantly my monoblocks do not have an on/orr switch and i am a bit concerened about running them through my vintage pre amp's power inputs.

given this situation can anyone provide any expereinces witht he jr regarding "sound, compression of dynamics and noise reuduction and all the other fun stuff about Pc's. I just cant seem to fathom dropping a 1-2K on a bpt or similar fancy pc.

Another related issue....anyone think it would be possible to built an exodus filter where the on off swtich applies only to two inputs (monoblocks) and the rest of the jacks as an always on?

I have limited space so the idea of running another strip of an "always" on exadus seem a bit rundundant...

thanks all , including kevin for your suggestions

Kevin... what would that as well as their 15amp PC cost?

Give me a call.... it may be easier just to chat on the phone and get your situation squared away rather than posting on the forum.
