Genz Benz Shuttle 9.0 discussion thread

Not open for further replies.
I would give my left N*T to retro my MAX12.0 with dual 9.0 power amps... tru enough
The power of the 9.0 is the bomb and I would kill for a retrofit



What would be more fun: the ShuttleMax 18.0, with 2 channels of 900 watts @ 4ohms, or the Shuttle 12.0, with a full 1200 watts into 4ohms in the same 4lb package as the Shuttle 6.0 and 9.0? I'm loving the 9.0 so much that I hardly see the need for even more headroom, but is there ever such thing as too much power?
 
hmmmmm the plastic C gave it away....

The Genz amps are powered by Bang & Olufsen's new ASX2 series of integrated output board / power supply boards (thier latest & greatest according the press release :p)

The 6.0's use the model 125ASX2, conservatively rated at 550 watts. From your description, you're looking at the 250ASX2.. rated at 640 watts down to minimum 8 ohms. I'm thinking this is where GB's PHAT topology comes in... some propriety something or other that allows that board to operate down to 4 ohms, thus the 900 watt rating. I bet its a beast. Here she is:

Sooooo based on the somewhat established schedule..... I think we can expect the Shuttlemax 9.0 to be announced right around June - July 2010? Yeas?

:D:D

lol

Having just bought one of these, I researched this power module some more to satisfy my own curiousity. I'm interested in knowing a bit more about what Genz has done to enable the 900 watt output at 4 ohms from this unit. I realize there is additional thermal dissipation designed into the Shuttle 9.0. I'm also interested in the harmonic distortion at the rated 900W output, as well as how long a pure 900W/4 ohm output could be sustained. I know that in BTL mode, this 250ASX2 is rated for 640 Watts into an 8 ohm load with 10% THD. In addition to the thermal design, I'm wondering if Genz has obtained a customized module that reduces the current limiting, allowing for the operation at 4 ohms in BTL mode. This seems to be a logical path.

I realize this inquiry is pretty academic. According to B&O, the modules were designed with the knowledge that they would be used for highly dynamic musical signals, so their technical specifications are very rigorous, and come from a worst-case scenario.

I'd love to hear from agedhorse on any details about this - the technical side of this unit is extremely interesting. Of course, I understand if parts of it aren't meant for public consumption. ;)
 
It is my my understanding that Genz Benz is pretty hush hush on the Phat subject. I believe they would like to keep that to themselves and I can understand why.

I can see that too. But, given that the module specs are public domain, I'm thinking there is some detail that may be open for discussion. I could be wrong.

Patents pending allow for disclosure, but of course it's up to the Genz Benz crew to determine what they discuss.

The unasked question is always unanswered.
 
Well, Just picked up a shuttle 9.0 and a Berg AE210. I still have my AE410 as well and may pick up AE112 again and see what I like best.

I've been using the 9.0, AE210 combo on smaller gigs for a
while now. I've loved the sound from the stage. The other
night I had a friend sit in for a while. They played through a
number of styles using fingers, pick, and slap. This little cab
and head sounded just great with my Fender Am Dlv J V.
 
This is what the manual states:

For a clean tone and using a Passive bass your Tube Gain and Preamp Volume settings may be set to similar positions. For a clean tone using an Active bass your Tube Gain setting should be set more towards the 9 o’clock position and the Preamp Volume at noon to 2 o’clock positions.

I've had good luck keeping the gain and pre volume the same up to about noon - 1 o'clock. After that I turn up the master to get more volume.

I suppose you could max the pre volume and use the gain to get more volume (up to about 1 o'clock). This assumes the grit comes only from the gain and the preamp volume doesn't introduce any noise. This might work but I like to keep both volumes below about 3:00 (so to not introduce any potential noise).


I'm looking for the cleanest volume I can get from the 9.0.
What's the highest setting you guys have found for the tube
gain before it starts to sound too affected? I still haven't
quite gotten the feel of it.
