Genz Benz Shuttle 9.0 Appreciation Thread Part II Shuttle 9.2 included

Very subtle alteration to Q/slope... really it's a fairly minor change, maybe a little bit rounder but when you consider the whole package, including the 3DPM, it's hard to assign attributes of each part to the overall sound. It's part and parcel of the package.

I'm sorry could you be a little more vague please?:D

Trimmed some of the low end out, made the mid scoop a little less, added hi-definition 3D glasses, or an extra kanuter valve, etc......?

A mild adjustment to the framastat and a refinement to the muffler bearing's real loaded thrust washer.

Really, the changes are so minor that it's hard to describe because it's inclusive to the more substantial effects of the 3DPM circuit. They can't be separated apart. Overall, the effect is a little smoother rounding out of the low end, a very subtle change to the depth and Q of mid scoop action character and an even smaller change in the flavor of the HF attack. These changes compliment the effects of the 3DPM.

My 2c is that I never use distortion; so the 3DPM thing isn't of interest to me for its advertised characteristics (not to say the new amps are not smokin).

I have started using the shaping buttons more recently for my Fender Jazz; which can be a little harsh sounding. For that instrument the scoop button can help the big down low and big up top thing. Of course, my Sadowsky pre does that even a little better...

The 9 is a real workhorse for me.

For me, IMO/IME, the real kicker here is the 3DPM circuit. It is one of the things that has made the Streamliner amps and the Shuttle Max 9.2 "feel" so good when you're pushing the amplifier hard. Now that the feature is included in the new Shuttle 6.2/9.2 and the Max 12.2 just makes the entire GB lineup even sweeter!

Kind of have to play it to see what I'm talking about, but in essence, and Andy correct me if I'm wrong, but a simplified explanation of the circuit is that when the power amp is pushed to limiting, it is the low-end frequencies that get the 3DPM treatment, leaving the mids and highs essentially unaffected. In doing so, the bottom end gets warm and thick when pushed, not unlike an all-tube power amp when driven hard, but leaves the mids and highs sweet. This is opposed to regular SS amps, and especially Class-D amps, which can sound and "feel" less than stellar when they've reach their amplified limits.

I don't believe the 3DPM circuit is about creating distortion, per say, I believe t is about limiting it at the most obvious place - the low end, as this is where the greatest amounts of amplified power requirements happen when you are pushing the amp into limiting. By controlling the low-end, it frees up the mids and highs to remain free of bad sounding SS artifacts when you are pushing the amplifier really hard.

Heck... I'm not a engineer. I can only speak from personal experience and say that my Steamliner 900, Shuttle Max 9.2 and Shuttle 9.2 absolutely "feel" wonderful when I drive the amplifier section really hard. This happens whether or not I'm going for a distorted sound via the gain control or a clean tone, so the benefits should be usable and felt by any player. It's good stuff!!! :bassist:

For sure though, if you don't find yourself pushing your 9.0's amp really hard, then no reason I can see to make the switch.

Sounds more to me like a throttle on the main power consumtion discumbobulator.

I suppose one way I could tell the difference is use my Streamliner 900 as a power amp for my 9.0 and compare that feel to the feel of the 9.0 on it's on.

The 3DPM is not part of any distortion generation, it governs and moderates the negative characteristics that can occur when a power amp is overdriven. In fact, it reduces some of the negative artifacts of power amp distortion while allowing the positive sapects to contribute.

Correct, in that it's not about the distortion. It's a complex compression and limiting circuit that has some dynamic parameters that operate differently depending on how hard the amp is pushed, the frequency spectrum and the risetime of the signal, allowing it to respond differently to say a slap type signal. It's release also related to the decay envelope of the bass signal, again to help eliminate the negative artifacts that can be attributed to the feeling of lost dynamiics. There's a lot of moving parts involved that does not lend itself to a simple explanation.

Also, it really doesn't come into play until the last 3dB of power amp headroom, so if you aren't driving the amp hard, it's unlikely to have much if any impact BUT if you are driving the amp hard, it's contribution is certainly significant.

OK, but if I played my amplifier that loud in the stage mix, my band would disown me.

I'm still getting used to my Shuttle 9.0, but I like it. I have the bass and treble buttons pushed, but dial the treble back a bit.

From reading all the posts in part 1 of this thread, I'm trying not to freak out about the limit light coming on intermittently. It doesn't sound like it's squashed or "running out of room" like my F1 could at high volumes.

The Shuttle 9.0 is heaven. Along with Avatar B410 Neo (4 ohm), no need for any pedals. Plenty of power and plenty of tone at a very light weight. Wonderful product

I run mine through Avatar 210 on top a 112 NEO. Standing up right it makes for great monitors on big stages and I have plenty of volume in any rehearsal situation.

I still want Ubers some day, wondering if I should get two 210s a 410 or a 210+1288. I'm getting use to the tower set up and it's sound projection, don't know if I'd like one Uber 410 sitting so low.

So my 9.0 started acting a bit weird tonight. I gigged with it last weekend and haven't turned it on since then. Anyway I turned it on and it did its usual warm up. Then I got a lot of noise. The noise sounded like an AM radio that wasn't quite tuned in to it's station quite right. Know what I mean? So I started playing anyway cuz my son wanted me to show him how to play a Beatles tune. As I played it popped a few times then the noise went away and didn't come back. Yet. So what do you all think, a little dust somewhere?
