Title: New lower priced Bryston ‘IS Series’ BIT Product
Post by: James Tanner on 25 Jan 2012, 07:28 pm
MEMO: To All Bryston North American Dealers
SUBJECT: New ‘IS Series’ BIT Products


Premium Power Conditioning at Entry Level Prices

Bryston is pleased to introduce the new BIT ‘IS Series’ of premium power conditioning at entry level prices.

Like all Bryston BIT products, IS Series models provides true isolation from the external power grid, noise filtration using toroidal isolation transformers featuring proprietary NBT technology and high levels instantaneous (peak) current on demand.

To achieve the lower price point, the ‘IS Series’ does not include ‘series mode surge suppression’, which remains available in other Bryston BIT models.

There is no compromise in the IS series – it performs like all Bryston BIT conditioners, offering sparkling performance with noticeable increase in dynamic range, imaging, bass response, depth in audio, and increased definition in video.

There are 3 models available: 5 Amp, 15 Amp, and 20 Amp, - 120 Volt/60Hz
                              
Specifications:

•   Input Voltage and Frequency: 120VAC Range ± 10% (57-63)Hz
•   Input Current Limiting: N/A
•   Input (inlet) connector Rear panel: 15A inlet (20A on IS-20)
•   Output voltage: 120V AC
•   Output connector: Medical Grade Duplex 15A  Outlets
•   Surge Suppression: Not supplied
•   Noise Reduction: Performs as low pass filter, attenuating noise from 2kHz to 1mHz, with attenuation of 12 db/decade to 500 kHz.

You've tweaked my ears with this new product.  Could you share the Canadian and U.S. list prices for all models?
 
In addition, with a 4B-SST2, which would be the recommended model.  I have noted that the 4B-SST2 manual states that the actual current draw into 4 ohms at maximum output is 2100 watts, which actually equates to 17.5 Amps @ 120 volts, which is what is confusing me.

IS Series Single Phase Input  -  120V
            

BIT-IS 5 B 17   IS Series Single 5 Amps/120V/60Hz        1,095.00
BIT-IS 5 S 17            
            
BIT-IS 15 B 17   IS Series Single 15 Amps/120V/60Hz     1,495.00
BIT-IS 15 S 17            
            
BIT-IS 20 B 17   IS Series Single 20 Amps/120V/60Hz    2,395.00


That power draw is not continuous.  I usually recommend a minimum of 10 amp Torus unit with a 4B SST2

It protects you against surges and electrical spikes on the power line. Some areas have serious issues with power spikes and many areas with lightning affecting the power grid.

Hi Steve

I would have to get that from engineering - what I can say is I have had people call me and tell me that they had a lightening strike and all that survived were the units attached to the Torus.

That's one I can testify to as my gear is connected to three Torus Piu's.
 A few years back we had a storm here,all my gear was safe except my computer as it was connected to...               a :finger:,monster  conditioner.She was fried.
Besides what the Torus does for the music,I wouldn't be without one as the protection is superb.
Could have been out around 70-80 grand :o.

Thanks....that's all I need to know.  Eight months ago, I moved to a house that is on a elevated ridge and there are  several tree on the property with lighting strike scars.   I just did a quick calculation of replacement costs for Bryston gear, B & Ws, etc. and it was north of $70k USD.  $3k for a BIT is looking like cheap insurance.

When will the 19" silver face plates become available for the BIT 20? 

(There is also tornado damage about 1/4 mile away but I don't think that a BIT will help that problem. :>)

I must have misunderstood the availability of 19" face plate for the Bit 20.  I ordered a BIT 20 with 19" silver front; AA just called and said that they had talked to Bryston and 19" aren't available and aren't on the "drawing board" for the BIT.

Hi James,

I'm really interested in adding one of your conditioners to my system shortly, going on what you said above, unless I've missed something, I take it for the UK are we getting different model numbers compared to the US?

I've got a very similar system to Alpha with 7B's instead of a 4B and a BCD-1 + a TT, I take it as long as the budget will stretch I will be best to go with the UK equivilent of the BIT20?

Yes the 240 volt 50Hz BIT versions are BIT-4, BIT-8 and BIT-16 and are the maximum AMP ratings.

I'm guessing I need a bit 20. The 7's are connected to a dedicated 20 amp line.
2 7/BSST2
BDA-1
BDP-1
BDC-1
Bat 32SE
any thoughts?

Hi bjski

If you have the new 7B's then the instantaneous current draw the BIT provides is not required so a BIT 15 for everything else makes sense. Also remember that the BIT also provides Surge protection and Isolation from the outside power grid as well so if you wanted those features on your 7B's then I would recommend the 20 amp BIT.

I ordered my Bit 20 today from GTT Audio in New Jersey. Looking forward to having protection and a constant 120v in the summer months. We are notorious for having brown outs and low voltage. Wondering if I'll hear a difference in sound.

I don't believe the BIT 20 will help with brown outs, as I don't see AVR capabilities.  I purchased a Torus AVR to solve my power supply issues [but returned it due to issues].

My town is one of 10 in the state of NJ that supplies it's own power to the town. The town then uses this as another revenue source by adding an extra 7 cents a kilo watt.
The system is very antiquated. The power sub station floods out several times a year. We loose power constantly in the summer. The voltage will dip down to 106-104 volts during peak demand. The circuit board was ruined on my central air conditioning from the fluctuations in power. My refrigerator had problems caused by the low power. My home theater sub was ruined by one of the power surges. (before the Monster avs 2000)

We were without power for 6 days this past summer from the hurricane.

I don't play my 2 channel system when the voltage is low.However the home theater will play.

BJ

I had purchased the Torus CS 15 AVR which is an amazing product and it kept the voltage 120V +/- 5V.  However, my unit [I have no idea if this has happened with others] would make an electronic crackle sound when the relays would make the change to the output voltage.   I'm not a big fan of additional noise so I returned the unit to my dealer.  I have a Torus CS 15 now and love it.  Kudos to Plitron.

Hi - we are looking at offering the BIT in 220 and 240 volt versions - so far there has not been much demand outside North America.

Hi James,
any update on the 240 Volt versions?
I'd be looking for a price for a pair to feed the 14BSSTs.
I haven't seen the system demand over 2.8 kVA so a pair
of 8 Amp units would be ideal.

James, Just to clarify, my system is 2x7B's, SP3, BDA-1, BDP-1, BCD-1, BHA-1 soon, making 7 items in total, if I were to go with a BIT 16, would this be my best option? and would this give surge protection to my whole system including the 7B's as well as a clean supply, basically optimising my system?

I guess as there are only 6 outputs though I'd have to maybe sacrifice the BCD-1 to just plug into the wall socket as this is my least used component nowadays.

I live in the US mid-West where the weather can be very electrically active, especially in the summer;   purchased the BIT mostly for surge/isolation protection.  (no help for those odd looking funnel clouds, however)  I have three heavy duty Belkin multi-outlet boxes to add additional outlets.

The other option that I have done is to make my own using multi gang electrical boxes, high grade outlets and 12 gauge wire.  When I decided to plug everything into the BIT 20, I used the four, 10 outlet Belkin boxes that I had sitting around unused.  (For scientific accuracy, I just counted the stuff plugged into the BIT 20; twenty-five.

I'm beginning to realise why they all have so many sockets now!
I'm thinking of a pair of BIT 8s with one plug into each.
Don't think the cheaper IS series have the full surge protection so do we have any indications on pricing yet?

Probably could manage with a smaller unit doing surge only for the cdp etc then use the optical out from the
computer and we're fully isolated.

Hi Folks,

Be aware if you add a 'power bar' or some such like product to get more connections do not plug your amplifiers into the power bar.  One of the advantages of the BIT is a very low output impedance and with amplifiers that is a really good thing (low impedance - high current).  So if possible you want the power amp as close as possible to the BIT.

Hi James,

Could you please explain, for us non-techies, what this means, why this is? I've got my 28b's in a power bar, (actually 2, the one plugged into the other) together with all my other equipment, on a separate 20amp fuse/wall socket, and wouldn't know or notice why that shouldn't be the way to plug them up. Sounds terrific....

Seem to remember the 28's don't benefit from the BIT? Soundwise that is?

Hi Marius,

Before we were developing the BIT products (Torus) we asked ourselves what would be the perfect power source for a large amplifier. Answer - a really low impedance/high current source.  The advantage of that is on transients the amplifier can deliver huge instantaneous power when needed.  The bigger the amplifier the more it seemed to matter in our testing. 

So what was the best way to accomplish this - a huge transformer :thumb:  What is important though is that you need an Isolation transformer - not just a filter transformer. There is a Primary and a Secondary and you are working off the magnetic field between the two halfs. That way you are never in Series with the outside world. We also found we had to increase the size of the transformer about 1.5 times the rating it required in order for the sound not to become a bit 'sluggish' . So the BIT transformers are double the size needed for a specific rating - EX - the 20 amp unit has a 40 amp transformer. It is a much more expensive way to go but it works!

Now once we looked at that we decided that maybe we could offer the instantaneous current draw application to the amplifiers directly by redesigning the internal transformer to have the same characteristics. So we did, and the newer 7B's, 14B's and 28B-SST's have those type of transformers internally installed.

So you are correct that one of the main features of the BIT is already part of the larger amplifiers design.

probably easiest to do that in the consumer unit for the room.

Hi Marius,

Bryston BIT Isolation Transformer Motivation

The concern Bryston had with a lot of power line conditioners available in the market was that many of them could restrict the current available to the amplifier. An amplifier can draw very high peak current, and wants to 'see' a very low impedance high current source from the power line. In fact, we even stated in our owners manuals not to plug our amplifiers into power conditioners. The Transformer based line conditioners we tested were too small to supply the peak current required and many of them were just Filters and did not provide Isolation -(Isolation means there is no mechanical connection between the outside power grid and your inside system power supply).

Also most of the surge protection was done using MOV’s, which are sacrificial and eventually will be destroyed with repeated spikes. Other issues with these MOVs is that they allow much more voltage through before they reacted (typically 300 volts and higher) and they shunt the voltage spikes to ground.

So we decided to try and develop a powerline Conditioner, Isolation and Protection unit that would not have the restrictions of the many units currently on the market from an amplifier performance perspective.

Benefits of Bryston BIT Power Isolation Units:

Benefit #1: Very low source impedance and high current for the power amplifier
BIT power isolation units present low impedance to any electronic device that is connected to them. A Single 20 amp BIT PIU has an output impedance of 0.2 ohms and can deliver 400 amp peaks (instantaneous current). The 100 amp unit only has .04 Ohms of output impedance. A typical 200 watt audio power amplifier demands 10 amps RMS current from a 120 volt line (1200VA) but may demand up to 50 amp instantaneous peaks. The standard residential wall receptacle can't supply the 50 amp peaks because they typically have higher nominal impedance. A BIT 20 amp PIU plugged into the same wall plug can supply these peak current requirements quite easily.

Benefit #2: Power surge protection using Series Mode Surge Suppression rather than MOV's
The BIT power products use the finest, most elaborate surge suppression technology available. Series Mode Surge Suppression does not shunt the spike to ground like MOV's do, and therefore the ground is infinitely more stable in a Torus power device. Additionally, most MOV-based surge suppression units allow as much as 300 volts through to the protected components, easily enough to do substantial damage, where as BIT surge suppression has clamping voltage onset of around 2V above peak nominal voltage. Torus units are built to meet 6000 volts, 3000 amps at 1000 repeats standard.

Benefit #3: Total isolation from outside power grid
BIT power products provide isolation through its finest designed toroidal transformer between the outside power grid and the devices being protected. Such isolation helps to reject external noise sources such as motors, lights, and dimmers commonly found in the home environment. BIT power products provide noise filtering at a range from approximately 2000Hz to over 1MHz – other regular transformer based products do not start operating until nearly 10,000 Hz.

Benefit #4: High Power Capability
There are 6 models of BIT power products available ranging from 5 amps to 100 amps and 120/240 Volts. BIT has recently introduced NEMA wall-mount units, which are typically placed at the hydro panel for whole-house or whole-room power line isolation and protection.

Benefit# 5: Low Noise
Bryston BIT products utilize ‘LONO’ (Low Noise) transformer design technology that eliminates audible noise in the power transformer regardless of line conditions, DC offset and over-voltage. BIT products perform at the NC10 level measured on the standard NC (Noise Criteria) – which makes them suitable for use in very quiet environments such as professional recording and broadcast studios.

Benefit # 6: Cleaner Power
Bryston BIT products utilize “NBT” (Narrow Bandwidth Technology) to attenuate differential and common-mode noise without external circuits or components, and starting at a lower corner frequency (2Khz) than other systems.

Hello James, sorry for the late reply ( I did not get an auto email ), I did contact PMC and took a while to get the correct information, for some reason they did not know about the product and hence was a little long winded.
The price quoted, well lets say I got the feeling its was a little inflated, so I went for the Torus AVR 2 16 amp it was better priced and came with more features being delivered tomorrow.
Sadly not a Bryston product but I did try my best and would pay a "bit" more for the branding ( no pun intended ).
Regards Clive.
